1 General

1.1 Ethernet TCP/IP Protocol ConverterThe RS232/485 – Ethernet TCP/IP – converter is designed for the connection of digital LumaSensePyrometers to the Ethernet network. Devices equipped with RS232 (max 1 device) and RS485(1 … 32 devices) UPP interfaces can be connected to the converter. The pyrometers can be readand parameters can be passed to them via the Ethernet. The converter operates as master onthe RS485 bus and as server on the Ethernet network. The data is transferred between thepyrometer and the converter via an RS485 or RS232 interface. The data from the converter tothe control system is transferred using the Ethernet protocol.

It is possible to connect up to 32 pyrometers with RS485 UPP Interface to one converter.

The device features 1 Ethernet port. The data is exchanged via a Dual-RAM memory.

The length of the cable between the pyrometer and the converter should not exceed 20 m whena device with an RS232 interface is used.

* The device supports “autocrossover”

3.5 ShieldShielded twisted pair cables must be used for the supply!

The shielding is to be connected with large surface on the mating connector housing!

The connection to the potential equalization automatically takes place when the device ismounted on the DIN-rail. Ground the top hat rail to which the converter has been clipped. Theconnection wire must have a cross section of at least 10 mm².

3.6 Electrical InstallationConnect the 24 VDC power supply on the connector X2 to clamp 1 (24 V) and 2 (0 V). Thepyrometer bus will be connected on the connector X1 to clamps 4 and 5 (for RS485) or clamps 1und 2 (for RS232). For operation with RS485 the pin 4 on connector X1 must be connected to pin6, and the pin 5 must be connected to pin 7. The rotary switches S4 and S5 must be set to 0.

If the converter is physically the first or last device in an RS485-bus then the bus must beterminated. The RS485- switch must be set to ON, the RS485+ switch has to be on OFF. Theresistor integrated in the converter is activated. In all other cases leave the switches in theirs OFFposition. The data cable of the pyrometer must always form an in-line connection between thefirst and the last node. This in-line connection must end with a terminator.

3.7 Pyrometer Bus WiringThe pyrometer’s A1, B1 connectors need to be wired to the A2, B2 connectors of the previouspyrometer in the bus so that a series connection of the devices in the RS485 bus is created. Bothends of the RS485-bus must be terminated with a 120 Ohm resistor. For the wiring of the RS485we recommend the PROFIBUS-wires made by Siemens.


The following picture illustrates the RS485 interface connection of 3 pyrometers to theconverter.

Ethernet TCP/IP Protocol Converter Ethernet ∂ 13

4 Ethernet

To use the Ethernet converter with a client system platform independent commands and datacan be ex-changed by TCP/IP. The converter was designed to act as a TCP/IP server.

The network settings can be changed only if the converter is in polling mode.

4.1 Network-addresses, network-connectionsAfter switching on, the converter is waiting for data communication with a network-participant.In this case the converter is always prepared to react to ICMP messages (e. g. PING Request andReply). The functions of the ARP-protocol are also available.

4.1.1 IP-Address

The factory setting for the IP-address is 192.168.1.1, the IP-Address is modifiable by using thedelivery software “InfraWin-ET”.

4.1.2 Netmask

If the IP-Address is outside of the IP-Address range and/or the IP-Address range is subdivideddifferently, the netmask must be modified using the software “InfraWin-ET”.

4.1.3 Data Port

The TCP-transfer to send and receive is realized using the data port “default 2000”. Should thisbe a problem (e.g. due to a firewall), the port may be modified using the software“InfraWin-ET” or per software command.

4.2 TCP-connection setupIn the characteristic application in the TCP/IP-protocol, after switching on, the converter is in thestate "Passive Open" under an IP-Address and port number that was determined in theconfiguration. A connection must be established on the TCP/IP level before data can beexchanged. From this point onwards, commands can be sent from the client to the converter.After successful connecting, a full duplex data connection is available. The data stream isprotected by the TCPI/IP-protocol in both directions.

4.3 IT-FunctionsThe Ethernet converter also supports functions like Webserver and FTP functions. The ITfunctions can be used simultaneously with the Ethernet communication.

Ethernet TCP/IP Protocol Converter Ethernet ∂ 14


Ethernet TCP/IP Protocol Converter Communication Modes and Boot-up Sequence ∂ 15

5 Communication Modes and Boot-upSequence

The converter implements two separate communication modes, Polling mode and Burst mode,which are not active at the same time. The default mode of operation is the polling mode andthis is the mode the converter always enters following power-up.

The two modes are not active at the same time, but the user can command the converter toswitch from one mode to the other. The details of each mode and how to switch between themis described in the following sections.

5.1 Polling ModeThe Polling mode is a polled protocol in ASCII format, which allows the direct access to thepyrometer. The client system sends a request message to the pyrometer to obtain a readingvalue and the pyrometer sends a response message containing the requested value. In this casethe UPP command has to be sent as ASCII sequence corresponding to the manual of thepyrometer with address byte.

5.1.1 Request string structure

The data exchange occurs in ASCII format. These commands are ignored in burst mode.

∂ The device responds to the entry of a command with: output (e.g. the measuring value) + CR(Carriage Return, ASCII 13), to pure entry commands with "ok" + CR, or "no" + CR.

∂ Every command starts with the 2-digit device address AA, followed by two lower casecommand letters, and is finished with CR.

∂ The ASCII parameter "X” indicates a change to be made in a parameter. When used, thecommand contains the new value.

∂ A “?“ after the lower case command letters answers with the limits of the respective settings(only at setting commands, not at query commands).

To take a look at the commands and a short description, please see Section 5.1.2.

Example:Set emissivity of pyrometer with the address 05 to 60%:Request string: “05em0600” + in hexadecimal “30 35 65 6D 30 36 30 30 0D”Response string: “ok” + in hexadecimal “6F 6B 0D”

By simply replacing the pyrometer address from example 05 to 06 you can issue this command tothe next pyrometer.

Reference number: AAbn Output: XXXXXX (hex 6-digit)

Note: the letter “l” means the small type of “L”.

5.2 Burst ModeThe burst mode establishes “streaming” data flow from the converter with a selected samplerate to the user’s client system. The simplicity of this protocol allows for the maximum data ratemeasurements. The data is “streaming” asynchronous and therefore the client system mustreceive it carefully. There are only limited commands supported in the Burst mode, such as“Start”, “Stop” sending readings, Setting the “Sample rate”, “Dataport”, “IP-Settings”, “Baudrate” and “Device number”.

Note: Once you enter Burst Mode, the converter will no longer accept UPP commands.

5.2.1 Data Format of Measuring Values in Burst Mode

All measuring values recorded at a time are combined into a measuring value frame with fixedsize (one measuring value per pyrometer) and then transmitted together as a TCP packet.

Name Format Bytes Function

Index 16 Bit (Word) 2 0.. 65535 / every record contains a new number,so that the client system can detect duplicatedata and skipped records

5.4 Notes for ProgrammingAs soon as the operating mode burst has been set, the converter begins to send data on theRS485 or RS232 bus. In order to avoid the propagation of invalid data it is mandatory that avalid data record in the parameter region has been set (operating mode, number of devices andbus address of devices).

1. Set the device number and the bus address of the pyrometer with the softwarecommand “DN”

2. Set operating mode to burst with the software command “IF”

3. The data packets are a fixed size [6 Bytes + (4*number of devices)]

4. The cycle time is [(20 ms*number of devices) + configured wait time]

5.5 Example Program for a S7-1200Any Ethernet based programming tool can be used for connecting the Ethernet converter.The following example shows how the converter can be integrated into an Ethernetnetwork. The used control system is a Siemens PLC S7-1200.

The converter operates as a server, the Ethernet connection is established by the PLC. For aSiemens PLC the following blocks are required. The function blocks TSEND_C and TRCV_Cmanage the client connection to the converter. The two blocks simplify the implementationof a client application by encapsulating the functionality of three function blocks TCON,TDISCON, and TSEND or TRCV.
