General

The LocalNet - Basics

The LocalNet is used as a basis for unlimited, individual application of theDatCom components. The LocalNet is a data network that enables dataexchange by several FRONIUS IG’s with the DatCom components.

The LocalNet data network operates as a ring-shaped bus system. Asingle data link between the individual components allows communicationbetween one or more FRONIUS IG’s with the DatCom components. Thisreduces the cabling requirements for the DatCom components to a mini-mum.

DatCom com-ponents /Plug-in cardprinciple

DatCom components are alsoavailable as units with an externalhousing (boxes), to increase flexib-lity.

DatCom components are availableas plug-in cards (similar to on aPC). The FRONIUS IG has beenprepared for the insertion of fourplug-in cards within the housing.

9

Datalogger The Datalogger is the core of the LocalNet. It coordinates the data trafficand ensures that even large data quantities can be distributed quickly andsecurely. The Datalogger also stores the data for the whole system overlong periods of time.

Each Datalogger has two RS 232-interfaces- one for data transfer direct to the PC- one for remote data enquiry to a PC in another location via modem

and telephone line

Since June 2003, two versions of the Datalogger have been available:

Datalogger pro:The Datalogger pro stores the data from up to 100 inverters and 10 Sen-sor Cards / Boxes.

Datalogger easy:The Datalogger easy only stores data from the inverter and from theSensor Card / Box addressed with “1”.

Important! The term “Datalogger” refers to both the Datalogger pro andthe Datalogger easy, unless specifically referred to by name.

DatCom com-ponents /Plug-in cardprinciple(continued)

COM Cards The COM Cards enable data linking of the FRONIUS IG to the LocalNetand to the DatCom components connected with it. Additionally, the COMCards provide considerable safety through the galvanic isolation betweenthe DatCom components and the inverter. Each inverter connected to theLocalNet must contain COM Cards.

Note! Every FRONIUS IG that is to be monitored requires a COMCard, even if the system contains only one FRONIUS IG. TheCOM Card provides the interface between the FRONIUS IG andthe Datalogger.

The following number of DatCom components and inverters can be con-nected as a maximum to a total system (as of December 2003):- 100 FRONIUS IG inverters (the combination of different types is

permitted)- 1 Datalogger pro- 10 Sensor Cards / Boxes- 10 Public Display Cards / Boxes

The system has, however, been designed so that DatCom componentsdeveloped in the future can easily be added to the system.

Inserting plug-in cards

Warning! Supply voltage can be a hazard to life and limb. Theconnection area may only be opened - by licensed electricians -when not under voltage.

Warning! Supply voltage and DC voltage from the solar modulescan present a hazard to life and limb. The plug-in cards may only beinserted when the FRONIUS IG- is disconnected on the power side (AC side)- is disconnected on the solar module side (DC side)

To install any of the FRONIUS IG plug-in cards, proceed as follows:- Set the FRONIUS IG to “Standby” (see “The Setup Menu” section in

the FRONIUS IG Operating Instructions)- Disconnect the FRONIUS IG on the AC side as well as the DC side- Open the connection area - see the FRONIUS IG Installation Instruc-

tions- Push the display aside and lift up forwards- Loosen the fixing screw (1) and remove the plate associated with the

plug-in port that will be used.

The plug-in cards communicate within the FRONIUS IG via its internalnetwork. External communication (LocalNet) takes place via the COMCards. Each COM Card has two RS-485 interfaces: an input and anoutput. The input is marked “IN” and the output “OUT”.

Cable connec-tion

The DatCom components withexternal housing also have an input“IN” and an output “OUT” for datacommunication within the network.

A FRONIUS IG with a COM Cardor a DatCom component with exter-nal housing is referred to below asa “LocalNet client”.

Inserting plug-in cards(continued)

DatCom com-ponents withexternal hous-ing

DatCom components with external housing are designed in accordancewith “Degree of protection IP 20” (NEMA 1). DatCom components withexternal housing (boxes) are therefore suitable for interior applicationsonly, or must be placed in an appropriately rated weather-proof box.

Note! Danger of damaging the plug-in cards. Please follow thegeneral ESD rules when handling plug-in cards.

In principle, each plug-in card can occupy any available plug-in port.However, the following recommendations should be taken into considera-tion:

- When all plug-in spaces are to be used:Insert the COM Card in the far left slotInsert the remaining plug-in cards in the other slots

- When not all slots are used: Insert plug-in cards as required

- Insert the plug-in card (2) into the slot- Secure the plug-in card (2) using the screw (1)- Close the housing- Connect the AC and DC lines on the FRONIUS IG

12

The data connection for the LocalNet client uses 8-pole data cables (1:1-connection) and RJ-45 plugs. A commercially available crimping tool canbe used to easily assemble the cable.

Data cable

To do this you require:(1) One 8-pole ribbon cable(2) Two RJ45 plugs (8-pole network plugs)(3) One crimping tool

The above mentioned items are available from FRONIUS under the fol-lowing item numbers:(1) 8-pole ribbon cable 100m (328 ft) roll (40,0003,0384)(2) RJ 45-plug (43,0003,0815)(3) Crimping tool (42,0435,0019)

Proceed as follows to assemble thedata cables:- Shorten cable to the required

length using the crimping tool- Strip the cable ends using the

crimping tool

Note! When fitting the RJ45plugs, remember that thecores must have the sameposition in both plugs (e.g.black = PIN1, white =PIN8)

For increased data security in an insecure environment, we recommendan 8-pole 1:1 LAN network cable (e.g. CAT5 cable, screened and twisted)as an alternative to the ribbon cable. These cables are obtainable pre-assembled from FRONIUS:- CAT5-cable 1m (43,0004,2435)- CAT5-cable 20m (43,0004,2434)- CAT5-cable 60m (43,0004,2436)

Should you wish to assemble these twisted cables yourself, it is vital thatyou adhere to the following pin assignment for the RJ45 plug:- Pin 1: +12V (white/orange)- Pin 2: GND (Orange)- Pin 3: RX+ (white/green)- Pin 4: TX+ (blue)- Pin 5: TX- (white/blue)- Pin 6: RX- (green)- Pin 7: GND (white/brown)- Pin 8: +12 V (brown)

Note! The data cables are not UV resistant. When laying the datacables in the open air, protect them from sunlight.

Data cable(continued)

Insert the termination plugs as follows:- On the “IN” input for the first LocalNet client- On the “OUT” output for the last LocalNet client

Two termination plugs are includedwith the Datalogger.

The power for DatCom components is supplied independently of theFRONIUS IG. This ensures a power supply even when the FRONIUS IGis not being supplied by the photovoltaic modules. The DatCom compo-nents are supplied via the COM Cards or by plug-in power packs, allowingthe Datalogger to save all data at night as well.

Note! It is possible to deactivate the power supply of some COMCards in PV systems with more than 12 FRONIUS IG’s. This canbe done by removing the AC fuse (MST 315mA/250V) from everysecond COM Card, as shown in the illustration. This reduces thepower consumption of the DatCom system. Note that the poweredCOM Cards are distributed equally to all phases.

Note! Once wiring between the system components is completeand the FRONIUS IG has been connected to the grid, the greenLED must light up on all LocalNet clients. If this is not the case:- Check the cable connections- Check whether all FRONIUS IG are connected to the mains

If the green LED is not alight for individual DatCom components:- Plug a supplementary power pack into the appropriate DatCom com-

ponent.

The COM Cards are responsiblefor powering the DatCom compo-nents. The integrated power packon the COM Card is supplied withpower via special contacts in theplug slot. These contacts are liveeven when there is no DC powerfrom the photovoltaic array.

One COM Card can supply threefurther DatCom components. Aspower supply is provided via thedata cable, the DatCom boxes arealso kept supplied.

Power Pack Each DatCom component, whetherit is a plug-in card or an externalbox, has a 12V connection socketfor a power pack.

Note! Should a system onlycontain one FRONIUS IG,but more than 3 DatComcomponents, the COM Cardwill not be able to supplysufficient power for all Dat-Com components. Thatmeans the green LEDwould no longer be lit up onall DatCom components. Inthis case, plug the addition-al power pack to a DatComcomponent on which thegreen LED is not lit up.

A power pack can supply up to eight DatCom components. No additionalsupply cables are needed for this. The power supply between the compo-nents for the data communication is provided via the communicationcable.

Note! Only the power pack available from FRONIUS is guranteed tosupply the DatCom components. Do not plug in any other power pack.

Note! The power pack is also available with the correspondingplug for the USA and UK.

18

The LocalNet automatically recognises different DatCom components(Datalogger, Sensor Card, ....). However, no automatic differentiation ismade between several identical DatCom components. In order to defineevery system component (FRONIUS IG or DatCom component) clearly inthe LocalNet, each system component must be given an individualnumber (=address).

The FRONIUS IG’s address may be set directly using the display. CertainFRONIUS IG designs have no display. In this case, the address is set viatwo keys. The remaining DatCom components have a special settingwheel for addressing. A small slotted screwdriver is required for this.

See the FRONIUS IG Operating Instructions for details on how to set theaddress on the FRONIUS IG.

Note! Two identical devices in a network must not have the sameaddress. If this occurs, the Datalogger will not record dataproperly.

Example:- Permitted:

FRONIUS IG “Address 1”, Sensor Card “Address 1”- Not permitted:

FRONIUS IG 20 “Address 1”, FRONIUS IG 30 “Address 1”

Detailed description of the DatComcomponents

Datalogger

General The Datalogger is available as a plug-in card and as a box. The Data-logger is required to cross-reference several DatCom components or IGs.

Note! The total network must not contain more than oneDatalogger.

The Datalogger takes over the system control as the only systemcomponent with a real-time clock. It constantly determines whichequipment is in the system and regulates the data traffic betweenindividual system components.

The following DatCom components are available at the present time (asof December 2003) and are discussed in the following sections:- Datalogger- COM Card- Sensor Card / Box- Public Display Card / Box- FRONIUS IG.access

General

Proceed as follows for all DatComcomponents, irrespective ofwhether they are a plug-in card or abox:- Turn the setting wheel (16) to

the desired address using asuitable slotted screwdriver

Important! The Dataloggeraddress does not need to be set,as there can always only be oneDatalogger in a system.

The connection to external data processing using a PC is also made viathe Datalogger. Additionally, the Datalogger pro saves the data from allinverters and Sensor Cards / Boxes in the system.

The Datalogger pro can administer the following maximum number ofsystem components, and save their operating data:- 100 FRONIUS IG inverters (the combination of several types is per-

mitted)- 10 Sensor Cards / Boxes- 10 Public Display Cards / Boxes

Note! The Datalogger easy only stores the data of the FRONIUSIG and of the Sensor Card / Box addressed with “1”.

General(continued)

The Datalogger has the following connection points:- Card: Two RS232 interfaces with 9-pole submin connectors- Box: One USB port and one RS232 interface

These ports are used for data transmission:- direct to the PC- for remote data enquiry to a PC in another location via modem and

telephone line

Note! The 9-pole standard-AT-AT or null modem cablemust not exceed a length of20 m (66 ft).

Important! The interface cable isnot included with the Datalogger. A1.8 m (6 ft) long interface cable canbe purchased from FRONIUS(43.0004,1692).

21

Modem We recommend the following modem to connect to the Datalogger:US Robotics (or 3COM Courier) “V.Everything 56 K”.

You can also connect other 56K modems that support the V.90 Standard.However, please note the following:- Correct functioning together with the Datalogger is only assured with

the modem listed above- When using another modem, it might be necessary to adjust the

initialisation string (see section “FRONIUS IG.access”)

Note! Correct function together with the data logger is only en-sured if automatic call acceptance has been activated on themodem.

Automatic call acceptance is activated as follows:- Set the DIP switch (5) on the bottom of the modem to the “OFF”

position

Before: After:

ON ON

- The LED “AA” on the modem must be lit up

If a modem is connected to the Datalogger, a special configuration of yourDatalogger is possible. Within this configuration, the Datalogger sendsone SMS to a maximum of 3 mobile phones. To do this, the Dataloggerautomatically dials the number of a special service. This service is offeredby the telecom providers and is called SMS Centre (SMSC). The SMSCgenerates SMS messages out of the data.

The following providers have been tested by FRONIUS:- Germany: “D1 alphaservice” +49 171 2092522- Austria: “A1” +43 900 664914- Great Britain: “Vodafone” +44 7785 499993- Great Britain: “One 2 One” +44 7958 879889

Connections(continued)

To connect the Datalogger Box to the PC, please use a USB A/B cable.To connect the Datalogger to the modem, please use the cable thatcomes with the modem. For details on the wiring of this cable, pleaseread the operating instructions of your modem.

The general connections and display elements are described in the sec-tion “Connections and displays”.

Dataloggercard

23

The Datalogger stores the current data for all FRONIUS IG and SensorCards / Boxes connected in the system at defined time intervals. Thesave interval can be selected from a range of 5 to 30 minutes using thePC software “FRONIUS IG.access”.

The stored data are downloaded for further processing by PC. The PCsoftware “FRONIUS IG.access” enables you to pre-process, archive andvisualise your data in an efficient and easy-to-follow way.

The Datalogger’s memory lasts up to 3 years (approx. 1000 days) if thesystem only has one inverter. The duration of the Datalogger’s memorydiminishes depending on the number of FRONUS IG’s or Sensor Cards /Boxes connected in the system. If the LocalNet contains 10 FRONIUSIG’s or Sensor Cards / Boxes, the memory duration is only one tenth aslong (=100 days).

Important! Even if the maximum number of 100 FRONIUS IG’s and 10Sensor Cards is made use of, the memory duration of the Datalogger isstill 1000/110 = approx. 9 days (with a 30-minute memory interval).

Please observe the following information when the save interval is re-duced using the PC software “FRONIUS IG.access. If the save interval isreduced from e.g. 30 to 15 minutes, the memory duration is reduced byhalf (e.g. from 1000 days to 500 days).

Important! When the Datalogger memory is full, not all data are deletedimmediately. The latest data always overwrites the oldest data. The cur-rent data from the last PC download always remains in the Dataloggerover the total memory duration.

Saving data

The average consumption of a Datalogger is approx. 1.2 W when thesystem is in operation.

The COM Card has two RS 485-interfaces for data transfer(11) Input data communication “IN”(12) Output data communication “OUT”

The exact details of the design of the plugs and cables for data transfercan be found in the section “The LocalNet - Installation of the systemcomponents”.

The general connections and display elements are described in the sec-tion “Connections and displays”.

Connections

Power supply COM Cards are fitted with an integral power pack for powering the Dat-Com components. The integrated power pack for such a COM Card issupplied via special contacts in the plug slot. These contacts are also livewhen there is no network supply operation. A COM Card with an integrat-ed power pack can also supply three additional DatCom components.

The COM Cards enable theFRONIUS IG to be data-linked tothe LocalNet and the DatComcomponents connected with it. Forthis reason, the COM Cards areonly available as plug-in cards.One COM Card is required in eachFRONIUS IG.

(11)

(12)

COM Card

General

25

Important! Supplying additional DatCom components also functions ifthese are located in another FRONIUS IG or an external housing.

Each DatCom component has an LED with a green light that displays thatthe power supply is adequate. In the case of the COM Cards describedhere, the green light signals that the integrated power pack is functioning.

Note! The LED must light up if a COM Card is inserted and theFRONIUS IG is connected on the AC side.

If this is not the case, possible faults are:- The COM Card has not been inserted correctly.- The FRONIUS IG is not connected on the AC side.- There is a short circuit in the connecting cables to the other system

components.- The COM Card must supply more than three DatCom components.

If too many system DatCom components are being supplied by one COMCard, proceed as follows:- Plug a plug-in power pack into a DatCom component where the

green LED is not alight.

Note! Should a system only contain one FRONIUS IG, but morethan three DatCom components, the COM Card can no longersupply sufficient power for all the DatCom components. Thatmeans the green LED would no longer light up on all DatComcomponents. In this case, plug the additional power pack into oneof the DatCom components on which the green LED is not alight.

Further information on the COM Cards is to be found in the section “Pow-er Supply”.

Power supply(continued)

The output of a COM Card with integrated power pack for the supply ofadditional DatCom components is approx. 3 W max. (dependent on thesupply voltage).

Note! With particularly weak supply points (AC voltage less than200 V) it is possible that a COM Card may only supply two Dat-Com components.

Sensor Cards

General The Sensor Card is available as a plug-in card and as a DatComcomponent with external housing (Sensor Box). The Sensor Card / Boxoffers inputs for a total of six measurement signals to connect a variety ofsensors.- Two analogue inputs for two PT1000 temperature sensors- One analogue input for the evaluation of a voltage signal from an

irradiation sensor- Two digital inputs, e.g. for a power consumption sensor and a wind

speed sensor- One analogue input for evaluating a current signal

(0 to 20 mA; 4 to 20 mA)

The PC software “FRONIUS IG.access” enables visualisation of thecollected data from all sensors connected to the Sensor Card / Box.Some parameters of the Sensor Card / Box can also be displayed on theFRONIUS IG display.

The following information describes the different sensor types and inputs.FRONIUS offers pre-assembled sensors for measuring ambienttemperature, module temperature, insolation, wind speed and power.

Note! Each signal input must be configured using the PC software“FRONIUS IG.access”. Always connect configured inputs with theappropriate sensor. Otherwise, the Datalogger will register theempty inputs. The consequence is then a misleading value for thisparameter.

Channels T1 /T2

General explanation:Channels T1 (15) and T2 (16) are used for temperature measurementusing PT1000 temperature sensors.

Note! PT 100 temperature sensors and thermocouples are notpermitted.

Temperatures can be read on the FRONIUS IG display or through the“FRONIUS IG.access” software. Channel T1 is reserved for the moduletemperature, and channel T2 is reserved for the ambient temperature.

Example of channel assignment:- Channel T1 (15) for the mod-

ule temperature- Channel T2 (16) for the exter-

nal temperature

Theory of operation:- The temperature sensors

consist of resistors that altertheir resistance value when thetemperature changes

- The Sensor Card / Box meas-ures the voltage drop on theresistor when there is a con-stant current flow

- The Sensor Card calculatesthe temperature from thisvoltage drop

Example of set-up and commissioning:Measuring the temperature on the solar modules using a PT1000 temper-ature sensor on the T1 input (15).- Fix the PT1000 temperature sensor on the back of a solar module- Connect the PT1000 temperature sensor to T1- Activate channel T1 (15) using the PC software “FRONIUS IG.access”

- Name the channels (e.g. “Module temperature”)- Select unit (°C / °F)

Note! Do not allow the cable length to exceed 20 m (65 ft.) as thismay adversely affect the measurement.

(15) (16)

29

Analogueinput for volt-age signal

General explanation:The analogue input (17) is used to evaluate a voltage signal from anirradiation sensor. Values can be read on the FRONIUS IG display or byusing the “FRONIUS IG.access” software.

Example of channel assignment:- Irradiation sensors in the solar

module level

Function principle:- An irradiation sensor outputs

an increasing voltage withincreasing irradiation.

- The Sensor Card / Box meas-ures the voltage between the“+” and “-” inputs (17).

- The irradiation can be deriveddirectly from the voltage meas-ured.

Characteristic values:The Sensor Card has three measuring ranges on the analogue input (17).Select the appropriate measuring range using the “FRONIUS IG.access”PC software- Measuring range 1... 0 to 100 mV- Measuring range 2... 0 to 200 mV- Measuring range 3... 0 to 1000 mV

Important! For the proper irradiance measurement to be displayed, theirradiance sensor’s calibration factor must first be entered into FRONIUSIG.access. This factor is unique for each irradiance sensor. It is typicallylisted on the sensor’s data sheet or is printed on the sensor itself.

Example of set-up and commissioning:Measuring the insolation on the solar modules using an irradiation sensoron the analogue input (17).- Fix the irradiation sensor parallel to the solar modules- Connect the irradiation sensor to the analogue input (17)- Activate the analogue input (17) using the PC software “FRONIUS

IG.access”- Input the channel name (e.g. “Insolation”)- Set the measuring range- Input the conversion factor

Note! Do not allow the cable length to exceed 30 m (100 ft.) asthis may adversely affect the measurement.

(17)

30

Digital inputs General explanation:

The digital inputs D1(19) and D2(20) are used for evaluation of voltagepulses (e.g. from a current meter). The sensor data are evaluated usingthe “FRONIUS IG.access” software.

If a sensor is connected to one of the digital channels (19), (20) of theSensor Card / Box, the signal can be evaluated on the FRONIUS IGdisplay as well.

Example of channel assignment:- Channel D1 (19) for current

meter- Channel D 2 (20) for wind

speed sensor

Connect sensors that do not havetheir own voltage supply to:- D1 (19) or D2 (20)- “+ 5 V” (22)

Connect sensors with their ownvoltage supply to:- D1 (19) or D2 (20)- “GND” (21)

Theory of operation using a currentmeter as an example:- The Sensor Card / Box counts

the current meter impulses- The Sensor Card / Box calcu-

lates kWh used from the puls-es

- This requires the input of theconversion factor using “FRO-NIUS IG.access” (e.g. 10240impulses correspond to akWh)

(22) (19) (20) (21)

Theory of operation using a wind speed sensor as an example:- The Sensor Card / Box counts the wind speed sensor pulses- The Sensor Card calculates the wind speed from the number of

impulses per second- This requires the input of the conversion factor using “FRONIUS

IG.access” (e.g. 7 impulses/second correspond to one km/h)

31

First example of set-up and commissioning:Measurement of the power consumed using a current meter on channelD1 (19).- Install the current meter on the relevant AC lines- Connect the pulse output of the current meter to channel D1 (19) and

“+5V”.- Activate the channel D1 (19) using the PC software “FRONIUS

IG.access”- Give the channels the desired names (e.g. “Power consumption”)- Select unit (e.g. “kWh”)- Input the conversion factor

Second example of set-up and commissioning:Measurement of the wind speed using wind speed sensor on the channelD2 (20).- Install the wind speed sensor in a suitable position- Connect the wind speed sensor on the channel D2 (20) and “+5V” or

“GND”- Activate the channel D2 (20) using the PC software “FRONIUS

IG.access”- Give the channels the desired names (e.g. “Wind speed”)- Select unit (e.g. “km/h”)- Input the conversion factor

Note! Do not allow the cable length to exceed 30 m (100 ft.) asthis may adversely affect the measurement.

Digital inputs(continued)

Analogueinput forpower signal

The analogue input (23) is for connecting a sensor with a standardised 20mA current interface. To view the data of this sensor, “FRONIUSIG.access” should be used.

Example of channel assignment:- Connecting a humidity sensor

with current signal to the ana-logue input (23)

Function theory:- A humidity sensor with a cur-

rent signal is a sensor thatemits an increasing currentwith increasing humidity.

- The Sensor Card / Box meas-ures the current on both of theanalogue input legs (23).

- The humidity can be deriveddirectly from the current meas-ured.

(23)

32

Sensor Cardcurrentconsumption

The average consumption of a Sensor Card / Box is approx. 1.1 W whenthe system is in operation.

Characteristic values:The Sensor Card / Box has two measuring ranges on the analogue input(23). Select the measuring range you require using the “FRONIUSIG.access” PC software- Measuring range 1... 0 to 20 mA- Measuring range 2... 4 to 20 mA

Important! Input the conversion factor using the PC software “FRONIUSIG.access” so that the Sensor Card / Box can convert from mA to thedesired unit. The conversion factor is dependent on the sensor and mustbe determined from the sensor’s data sheet.

Example of set-up and commissioning:Measurement of the humidity using a humidity sensor on the analogueinput (23).- Install the humidity sensor at a suitable location- Connect the humidity sensor to the analogue input (23)- Activate the analogue input (23) using the PC software “FRONIUS

IG.access”- Name the channels (e.g. humidity)- Select unit (e.g. “%”)- Set the measuring range- Input the conversion factor

The Public Display Card is available as a card and as a box. The PublicDisplay Card is used to connect different large displays. Generalconnections have the same function as for the other DatCom components(setting wheel for addressing, bushing for plug power supply, LEDs).

The Public Display Card / Box has an RS232 interface through a 9-polesubmin plug. The 9-pole submin plug is used to connect a large display.Up to 10 Public Display Cards / Boxes can be located in one photovoltaicsystem. This means that a system can contain up to 10 different largedisplays.

Public DisplayBox

34

Configuration The Public Display Card / Box can be configured for two different displaytypes using the FRONIUS IG.access software.

Display type A:If the FRONIUS alphanumeric display or a display from Rico is connectedto the Display Card / Box, the setting “Display type A” applies. The PublicDisplay Card / Box is programmed to recognise which display isconnected automatically. This means that no further settings are required.

Important! If the display is to show values for irradiation, moduletemperature or external temperature, then the relevant sensors must beconnected to the Sensor Card / Box with Address 1.

However additional (not necessarily required) settings are possible viaFRONIUS IG.access. Please see the section on “FRONIUS IG.access” fordetailed information on these possible settings.

Important! In the case of the FRONIUS Public Display the Public DisplayCard is already integrated in the display, which considerably reduces thecabling requirement.

Display type B:If the setting “Display type B” has been selected, the Public Display Card /Box emits a defined data record via the serial interface.

Interface parameters:- 2400 baud- 8 data bits- 1 stop-bit- No parity- No handshake

The data record contains the following values:- Energy total (kWh)- Energy today (kWh)- Actual power (kW)- Irradiation (W/m²) … only available when a relevant sensor is

connected to the Sensor Card / Box with Address 1.

The output of the data record corresponds to the following format:- Energy total: 6-figure whole number, in KWh- Energy today: 4-figure whole number, in KWh- Actual power: 4-figure, two decimal places before the decimal point

and two after it, in kW (the decimal point is not transferred, becausebeing in the same place, it is superfluous)

- Irradiation: 4-figure whole number, in W/m²

35

The data record is made up of ASCII characters (97 bytes) and is set upas follows:- Start: #- Energy total: 6 bytes- Energy today: 4 bytes- Actual power: 4 bytes- Space: 16 bytes, 20 hex- Space: 2 bytes, 30 hex- Irradiation: 4 bytes- Space: 2 bytes, 30 hex- Space: 56 bytes, 20 hex- End: CR LF

There is no suppression of leading zeros.

Important! Applies to “Irradiation”: If there is no appropriate sensoravailable, this value is treated as a measured value of “0 W / m²”.

The average power consumption of the Public Display Card is approx.1.2 W.

“FRONIUS IG.access” 1.0 to 3.0.These versions of “FRONIUS IG.access” store all the data from the PVsystem in one single database. This database has the name “PV system”(e.g.: “Solar 1.fig”). On your computer, this database is located in thefolder “IG.access - Data”.

“FRONIUS IG.access” 4.0From Version 4.0, the database is split up into several smaller databases.This type of storage ensures fast access to the data even when very largevolumes of data are being managed. On your computer, the data may befound in the folder “IG.access - Data”. The data are divided into smallerdatabases here. The file “SystemName.fig” contains all the data neededfor displaying the bar diagrams. There are also files called “YearNos.igr”,containing detailed data for the years in question.

Updating from Version 3.0 to Version 4.0When you update your “FRONIUS IG.access” software to Version 4.0, adatabase distribution operation has to be performed the first time that youlaunch “FRONIUS IG.access”. You can either carry out this distributionoperation for all PV systems straight away, or do it one system at a time.Depending on the data volumes involved, and on the speed of your PC,the process may take 30 minutes or more.

Important! Database distribution is an operation that requires a great dealof “number crunching”. For large volumes of data, it is advisable toperform database distribution while the PC is not needed (e.g. overnight).

45

By default, the “General - General” tab is selected.- Enter the supply tariff for one kWh in “Earnings”. This is the rate that

the utility pays you for your solar energy.(e.g. “0.457” | “Euro”)

Energy comparison - General informationAfter every data transfer, “FRONIUS IG.access” enables an automaticenergy analysis to be carried out for your photovoltaic system. If an erroris detected here, you will receive a warning. Optionally, it is also possibleto forward this warning by e-mail.

For the “Energy comparison”, you must make the following settings:- Click on the “IG’s...” button- Specify which of the inverters in your PV system you want to have

checked.- Also specify the module capacity connected up to the FRONIUS IG

(provided that you have not done so already in the “PV power” field).

How does FRONIUS IG.access analyse the data ?After every data transfer, “FRONIUS IG.access” calculates the daily ener-gy fed into the grid, in kWp. This is done for every inverter for which moni-toring has been activated.

From the daily energy production fed into the grid by every FRONIUS IG,“FRONIUS IG.access” calculates a mean value. If one or more FRONIUSIG’s shows an inadmissible deviation from this mean value, FRONIUSIG.access generates an error message.

Important! In PV systems with only one FRONIUS IG, no such computa-tion is made. In this case, an error message is outputted if the invertergoes for all of one day without feeding anything into the grid.

Energy deviationThe reference variable for the maximum energy deviation is the meanvalue of the daily energy production of all FRONIUS IG’s per kWp. Themaximum energy deviation is determined by the greatest permissibledeviation of a FRONIUS IG from the mean. The max. permissible energydeviation can be set s, from 1 - 100 %.

Important! Do not set too low a tolerance (< 5 %), as this can lead to anincreased incidence of false error messages.

“General -General”

46

Threshold valueThe threshold value specifies the minimum level of grid infeed that mustbe achieved before an energy calculation will be carried out. If the meanvalue of the energy being fed into the grid per kWp is below this thresholdvalue, no energy comparison will be made. However, an error messagewill still be generated if a FRONIUS IG goes for all of one day withoutfeeding any power into the grid.

Entering a threshold value prevents false error messages beinggenerated on days with very low insolation or where the modules arepartly covered with snow. A value of 0.3 kWh / kWp may have either ofthe following meanings for grid infeed on the day in question:- Full power for only 0.3 hours- 3 hours’ operation at only 10 % power. This corresponds to a very

cloudy winter’s day.

Example of an energy comparisonThe following example is intended to illustrate how “FRONIUS IG.access”carries out an energy comparison. On one day, four FRONIUS IG’s (IG 1to IG 4) delivered the following infeed values (energy/day):

IG n° IG model PV power Energy/day Energy/day(Wp) (kWh) (kWh/kWp)

1 IG 60 5500 33 6

2 IG 30 2750 16.5 6

3 IG 30 2750 11 4

4 IG 30 2750 16.5 6

Mean value 5.5

Let us assume that the following settings were made in “FRONIUSIG.access”:- Maximum energy deviation: 10 %- Threshold value: 0.3 kWh/kWp

The mean value, 5.5 kWh/kWp, is well over the threshold value of0.3 kWh/kWp. This is sufficient to trigger an energy comparison.

The table shows that FRONIUS IG n° 3 has fed 4 kWh/kWp of energyinto the grid. This falls approx. 27 % short of the mean value (5.5 kWh/kWp) - a significantly wider deviation than the pre-set energy deviation of10 %.

The consequence would be an error message in “FRONIUS IG.access”.Where desired, a message can also be dispatched by e-mail.

A separate dialogue field appears. Clicking on the “OK” button ac-cepts the time set.

“Download” area:- For downloading the data to your PC, choose one of the following

options:- The content of the Datalogger since the last download (“From last

date”)- The complete contents of the Datalogger (“Total Datalogger con-

tents”)

Important! We recommend the setting “From the last date”, since thedownload takes place faster this way and data that is already archiveddoes not have to be saved again.

“Datalogger” - Select the “Datalogger” tab

“Delete data” area:- Only click on the “Delete” box in the “Delete data” area if all the data

saved in the Datalogger are actually to be deleted.

Note! You will not require the “Delete” box in normal operation.

“Administrator password” area:- Within the “Administrator password” area, a password can be granted

that protects the “Settings” area.- This password is independent of the modems (see explanation of the

“Datalogger modem” tab).

Important! In the ex-factory state (i.e. as delivered), no password isdefined. If you wish to access your photovoltaic system by modem, werecommend defining a password. This prevents any unwanted changesbeing made to the settings by other persons.

- Select the “Datalogger modem” tab

“Datalogger”(continued)

In the “Datalogger modem” tab, configure the modem that is connected tothe Datalogger. This is only possible if a direct connection to the Datalog-ger exists (via the PC interface).

- Select the modem “USR V.Everything”- Select your country: The Initstring (dialogue box “Initstring”) automati-

cally adjusts to the country requirements.

“Dataloggermodem”

52

Important! Personal editing of the Initstring is still possible if you insert ATcommands in the “Initstring” dialogue box or alter the existing AT com-mands.

- The maximum dial time is preset to 90 seconds. FRONIUS recom-mend retaining this setting. This setting determines the maximumtime that the modem is allowed for dialing in before the attempt isaborted.

- Entering password: You can protect your system by entering a pass-word. The password will be requested every time you dial up bymodem.

- Click on the “Initialise modem” button- Click on the “OK” button

In the event of an error in your photovoltaic system, you can be informedabout this via SMS. In order to activate the SMS mailing, proceed asdescribed below:- Choose the setting “SMS active (immediate)” or “SMS active (daily)”.

- Immediate: The error message is sent directly after the erroroccurs.

- Daily: The error messages are sent once a day, at the statedtime.

- Choose one of the services mentioned below:- The recommendation for your country is to be found in the sec-

tion “Datalogger”.- If necessary, you can also enter the phone number (e.g. for using

a service in another country - after all, the modem connected tothe international telephone system, ...)Example: If you wish to use the D1 service (Germany) from alocation in Austria. This necessitates a change in the D1 phonenumber from 0.... to 0049.... .

Important! When using the “IG.message” software instead of anSMS (text-messaging) centre:- Enter the telephone number of the modem to be used with

“IG.message”.

- When using one of the services recommended by FRONIUS, leavethe field “Password of SMSC” blank.

- If you will be using another service, ask for any password that may beneeded, and enter it here if necessary

- If required for your telephone connection, please change the dialling

“Dataloggermodem”(continued)

53

“Dataloggermodem”(continued)

mode to “impulse dialling”.- Enter the number of the mobile phone that the SMS will be sent to

- It is possible to enter up to three phone numbers- Separate the single phone numbers by “;”, without any blank

spaces- Please note: Not all services support the mailing of more than

one SMS (see section “Datalogger”)- When using a foreign service: Enter the dialling code of your own

country (for the example mentioned above, 0043xxx)

- When the setting “SMS active (daily)” has been chosen: Set the timewhen the FRONIUS IG should mail the SMS.- The Datalogger daily checks at this time every day to see wheth-

er any error messages have arrived. If necessary, the Dataloggerwill start the SMS mailing.

- Enter the name of the photovoltaic system (e.g. “Solar 1”) in the “PVsystem identification” field.- When an SMS is received stating the name of the photovoltaic

system, this makes it possible to find out from which photovoltaicsystem this SMS comes.

Check if your settings are correct:- Start the mailing of a test SMS by clicking on the “Send test SMS

button”.

Via modem, the Datalogger will now dial the number of the SMS servicecentre (SMSC). Within a few seconds, you should receive the SMS at thephone number given. The SMS reads as follows: “Solar 1: Test SMS”

Important! Sending the test SMS is performed independently of the pre-set time for the SMS mailing. Usually, it will only take a few seconds untilthe SMS reaches you. Depending on how the frequent the SMSC serviceis, the arrival of the SMS may also take a few minutes.

Important! In addition to the FRONIUS IG itself, the Datalogger is alsoable to detect service codes. The Datalogger generates SMS messagesas well.

“State 998” service code:If the Datalogger detects a non-functioning DatCom system for 24 hours(e.g due to a cable break), proper functioning of the monitoring system isno longer assured. Because of this, the “State 998” service code helps inmonitoring the DatCom system.

“State 999” service code:If a FRONIUS IG does not communicate with the Datalogger for morethan 24 hours (e.g. modules are covered with snow), the Dataloggersends the “State 999” service code by SMS.

54

As well as in the Setup Menu of the FRONIUS IG, several settings canalso be made from within the “Inverter” tab.- Choose the FRONIUS IG whose settings you want to change.

The following adjustments are available for the SMS mailing:- No SMS- All service codes

(SMS message caused by temporary and extended service codes)- Extended service codes (SMS message only caused by extended

service codes)

A. Temporary service codes:- These service codes only appear for a short time and prevent feed-in

during this time. Example: Cut-off due to instability of the grid- An SMS mailing will be started if a temporary service code appears

more often than 50 times a day.

B. Extended service codes:- Service codes that (at the least) refer to a deficiency of the FRONIUS

IG and (at worst) lead to a complete black out of the FRONIUS IG(e.g. hardware deficiency).

- An SMS mailing is started if an extended service code is displayedfor longer than 4:15 hours

Important! If no modem is connected to your Datalogger - meaning thatyou do not have the option of receiving SMS messages from your photo-voltaic system - we recommend the standard setting “All service codes”.

“Inverter” - Select the “Inverter” tab

55

Sensor values on the display:If your photovoltaic system contains a SensorCard / Box, the display onyour FRONIUS IG can show the following parameters:- Two temperature values- One insolation value- The value of a further sensor

The default (ex-factory) setting is that the display shows the values fromthe Sensor Card / Box with address 1.

Earnings:Here you can adjust the feed-in tariff and the currency. These values areused by the FRONIUS IG as the basic data from which to calculate theearnings.

Important! The settings for feed-in tariff and currency refer to the valuesthat are shown on the display of the FRONIUS IG, and not to the values inthe archive of the FRONIUS IG.access software.

Other settings:- As described in the FRONIUS IG operating instructions, you can set

the display illumination to “ON”, “OFF” or “Auto”.- The “Status” field allows you to switch the inverter into standby mode

(e.g. for maintenance work).- The “Copy IG setup” button is interesting for photovoltaic systems

with more than one FRONIUS IG. If you want to transfer stettingsfrom one FRONIUS IG to other devices, click on the button “Copy IGsetup”:- In the right-hand area of the display window, all the FRONIUS IGs

appear that are active within the LocalNet at this moment.- Click on the “<” and “>” buttons to drop or select the FRONIUS

IGs.- The settings you have just made are transferred to the selected

inverters when you click on the “OK” button.

Important! When using the function “Copy IG setup”, only the settingsthat have been changed are transferred - i.e. not a complete transfer of allthe settings.

“Inverter”(continued)

56

- Click on the “Activate sensor”button

- Give a name to the channel tobe assigned in the “Channelname” box, e.g. “Wind”

The Sensor Card transfers the data from the sensors connected to theDatalogger at regular intervals. The “FRONIUS IG.access” software regis-ters the new data at every download.

The data graphs are updated accordingly. To activate a sensor and assigna channel name, units, a measuring system range and a calibration factor,proceed as follows:- Select the required Sensor Card in the pull-down menu

(e.g. “Sensor Card 1”)- Select the first channel to be assigned in the large selection box (e.g.

“Current”)- Click on the “Set” button

The dialogue window for the channel to be assigned appears(e.g. “Current”):

“SensorCards”

- Select the “Sensor Cards” tab

57

- In the “Unit” box, specify the unit for the measured variable that is tobe captured using the sensor (e.g. “m/s” for the wind speed)

The Sensor Card has several measuring ranges on some channels. Themeasuring range is dependent on the sensor used. Select a measuringrange that agrees with the range of the sensor output signal. This valuemust agree with the sensor data sheet. Select the measuring ranges asfollows:

- Specify the range of the sensor output signal in the “Measuringrange” box (e.g. “0-20 mA”).

On some channels, the Sensor Card calculates the display value of aphysical value based on a sensor measurement that is based on anotherphysical value.- This requires that the conversion factor is inputted using the

“FRONIUS IG.access” software (e.g. “30” m/s wind speedcorresponds to 20mA output current from the sensor)

- The conversion factor is dependent on the sensor and is given in thesensor data sheet

- Enter the conversion factor for the sensor mesurement in the box“Calibration factor” (e.g. “30” m/s = 20 mA sensor current)

- Click on the “OK” button

- To assign the remaining channels proceed as described for the“Current” channel

- Click on the “OK” button in the “Settings” dialogue window

All required settings have now been assigned and the DatCom system willwork without any further settings needing to be made.

“Publicdisplay”

“Display type”:The “Display type” setting determines the type of data transfer betweenthe Public Display Card / Box and the public display.

If a display from FRONIUS or Rico is connected to the Public DisplayCard / Box:- Select “Display type A”

If you want to use the output of the standard-data record (see “PublicDisplay Card” section):Select “Display type B”.

“Energy offset”:For corrections to the energy value, the “Energy offset” gives you theopportunity of inserting an offset. This applies for the display of the totalenergy for the photovoltaic system: The offset is added to the value thathas already been determined by your FRONIUS IG.

The offset is also used to correct the values “Yield total” and “CO2 savingtotal”. The offset is automatically added to the values given.

Important! Only positive values can be shown.

“System factor”:The “System factor” multiplies all power and energy data for thephotovoltaic system (as well as the data calculated from this, such as e.g.CO2 saving and yield). This makes is possible for e.g. only a certainportion of the photovoltaic system to be shown on the display.

- Select the “Public display” tab.

59

“Publicdisplay”(continued)

“Earnings”:The Public Display Card / Box calculates the yield of the overallphotovoltaic system from the energy data of the individual FRONIUS IG’s.For this, it is necessary to key in the feed-in tarif. The setting for the feed-in tarif is independent of the setting for the feed-in tarif in the FRONIUS IGand FRONIUS IG.access.

When using an alphanumeric display (text display), it is possible to inserta currency in addition to the feed-in tarif. The currency can be given insingle to three-character abbreviations.

“Displaying data from the energy meter”:Should your Photovoltaic-System also have Sensor Cards / Boxes withpower meters connected, the public display is able to display the data ofthe energy meters. The power and energy data of up to three meters isadded and displayed for this.

“Default”:Resets the settings back to the standard values.

“Energy reset”:The Public Display Card / Box determines the energy data by polling allFRONIUS IG’s in the photovoltaic system. If a FRONIUS IG is removedfrom the photovoltaic system, or given another address, its relevantenergy data (daily, annual and total energy) will be retained. An “Energyreset” deletes the values for FRONIUS IG’s that are not found in thesystem.

If the alphanumeric FRONIUS public display is connected to the PublicDisplay Card /Box, further settings are possible:

60

The tab is available as soon as an alphanumeric display (text display) isconnected to the Public Display Card / Box.

“Display interval”:With an alphanumeric display, it is possible to show several valuesalternately. The display duration of a value until the next value isdisplayed can be set between 1 and 60 seconds.

“Text setting”:14 different values are available. A maximum of 8 of these values can beselected: The value selected and its respective unit (this is determined bythe Public Display) is shown in the second line of the display. The first lineenables a text belonging to the value to be shown with 8 figures at themost.

Important! When the time and date are shown, no text can be displayedin the first line. Reason: The first line has already been reserved todisplay the date and time.

“Favourite parameter”:In addition, one of the eight values can be defined as a favourite value.This value is then shown every second time the display changes.

Example : Identification of the AC power as a favourite value, alongsidethe other values “Energy total” and “Irradiation”. The display sequence isthen:- AC power- Energy total- AC power- Irradiation- AC-power- Energy total

Important! The values Module Temperature, External Temperature andIrradiation are only available when the relevant sensors are connected tothe channels of the Sensor Card / Box with Address 1.

“PublicDisplay”(continued)

The display window “Data transfer” appears. The new data are now trans-fered to your PC and added to the file archive.

Data transfer takes place in 3steps:- “Data transfer”- “Data are being saved”- “Archive data are being calcu-

lated”

- Select the menu item “Datatransfer” on the start page ofthe “FRONIUS IG.accesssoftware.

Important! The procedure can take a few minutes and chiefly depends onthe following factors:- Type of connection (modem or direct connection)- System size- Data enquiry cycle- Speed of PC

Note! When transferring data by modem, you can save telephonecosts as follows:

- Break the modem connection after the first step (“Data transfer ...”)- To do this click on the appropriate button in the “Data transfer” dia-

logue box.

After the system has operated for several datalogging cycles, there is nowenough data in the Datalogger to be evaluated on the PC.
