The Allen-Bradley RIO link creates data com-munication between the controller and the slaves(e.g. valve terminal/valve sensor terminal orremote I/O) distributed throughout the system.Baud rates up to 57.6K, 115.2K or 230.4 K Baudcan be set.
The valve terminal as a decentralized outputdevice proceses the RIO signals transmitted andcontrols the actuators which are connected. Thevalve terminal is supplied with current via an ex-ternal power unit (AC 115V/230 V/DC 24V).
The valve sensor terminal as a decentralizedinput/output device functions like a valve termi-nal. It also processes up to 30 inputs for valveposition sensors.
The actuators produce motion via air controlledby the valve terminal/valve sensor terminal.
The sensors provide digital valve position infor-mation and pass this on to programmable con-troller through the terminal.

Function
The valve terminal or valve sensor terminalshould be placed in the immediate vicinity of theprocessing unit. Connection to the control level ismade via the RIO link which operates on themaster-slave principle. The RIO scanner of theA-B PLC ® functions here as master, and thevalve terminal/valve sensor terminal as slave.The scanner transmits a message to the valveterminal/valve sensor terminal. The valve termi-nal sends a reply message to the RIO scanner.

Explanation of the function summary
The RIO node controls the following functions:
• The connection of the valve terminal/valvesensor terminal to the A-B RIO scanner of theprogrammable controller and to further RIOslaves via the RIO interface.
• The control of data transfer to/from the RIOscanner.
• The internal control of the valve termi-nal/valve sensor terminal.
The valve coupling unit of the valve terminalcontains the operating voltage connection anda decoder. This decodes the signals from theRIO node and transmits the pulses to the valves.
The valve-sensor coupling unit of the valvesensor terminal contains the operating voltageconnection and a decoder. This decodes thesignals from the RIO node and transmits thepulses to the valves. The electrical inputs forvalve position sensors, as well as two additionaloutputs are also situated here.
The valves control the flow of air to the actua-tors.
The valves are supplied with compressed air viathe common channels of the connection block.The exhaust and pilot exhaust from the valvesare also ventilated via these channels.
The connection block is connected to the com-mon cables of the pneumatic system via thepneumatic interfaces.

INSTALLING THE PNEUMATIC COMPONENTS
WARNINGBefore installation or maintenance work iscarried out the following must be switched off: • the operating voltage for electronic
components and/or inputs. • the operating voltage supply.• the compressed air.
You thereby avoid:
• uncontrolled movement of loosened hoses.
• undesired movement of the actuators con-nected.
• undefined switching states of the electroniccomponents.

Laying the hoses
PLEASE NOTE• A suitable seal should be placed under each
screw connection or each silencer.• If elbow connectors or multiple distributors
are used the air flow will usually be reduced.
General
• Connecting1. Push the hose as far as it will go into or
over the screw connection.2. Pull the locking ring over the hose connec-
tion or tighten the locking screw.3. For reasons of clarity the hoses should be
grouped together with:– hose straps or – multiple hose holders.
• Disconnecting1. Loosen the locking screw or locking ring
on the connection.2. Remove the hose.3. If necessary, replace the screw connection
by blind plugs.

24 V operating voltage connection
The connection for the operating voltage is onthe left-hand edge of the base unit of the valveterminal/valve sensor terminal.
Warning
• Use only PELV circuits as per IEC/DIN EN60204-1 (Protective Extra-Low Voltage,PELV) for the electrical supply.Consider also the general requirements forPELV circuits in accordance with IEC/DIN EN60204-1.
• Use power supplies which guarantee reliableelectrical isolation of the operating voltage asper IEC/DIN EN 60204-1.

By the use of PELV circuits, protection againstelectric shock (protection against direct and indi-rect contact) is guaranteed in accordance withIEC/EN 60204-1 (Electrical equipment for ma-chines, General requirements).
The following components of the valve termi-nal/valve sensor terminal are supplied separatelywith +24V DC via this connection:
• The operating voltage for the electronic com-ponents and/or inputs (tolerance: ± 25%)
• The operating voltage for the outputs (tolerance: ± 10%)

PLEASE NOTEThe electronic components and the inputsshow a greater tolerance range of the 24V DCoperating voltage than the outputs. Under cer-tain circumstances this can cause the elec-tronic components to indicate the switchingstatus of the outputs, although the latter arenot in the switched position (operating voltageof the outputs outside tolerance range).
The 24 V DC operating voltage of the outputsshould be tested whilst the system is operating.Please see that the operating voltage of the out-puts is within the permitted tolerances even dur-ing full operation.
PLEASE NOTE• Always connect the earth potential to pin 4
of the operating voltage connection.• Connect the earth cable of the left-hand end
plate to the earth potential with low impe-dance (short cable with large diameter).
By means of low impedance connections,make sure that the housing of the valve termi-nal and the earth connection at pin 4 havethe same potential and that there are noequalizing currents. You can thereby avoid in-terference due to electromagnetic influences.

Recommendation
• Protect the 24 V DC supply to the outputswith a fuse.
• The 24 V DC output supply should be con-nected to the EMERGENCY STOP circuit(see figure below).
The valves can then be switched off in an emer-gency. The electronic components continue torun and can display the error status and reactaccordingly.
PLEASE NOTECheck your EMERGENCY STOP circuritry, tosee which measures are required in order toplace your machine/system in a safe state inthe event of an EMERGENCY STOP (e.g.switching off the power supply to the valvesand output modules, switching off the com-pressed air supply).

Fitting the terminating resistor
PLEASE NOTEIf a terminating resistor is used, one of theRIO plugs on the last valve/installation termi-nal of a RIO line is not assigned. Protection inaccordance with protection class IP65 as perDIN 40050 is therefore no longer guaranteed.For this reason a protective cap must be fittedto the non-used bus plug. A terminating resistor is required at both endsof the RIO cable.
If the valve terminal/valve sensor terminal to beconnected is at the end of a RIO cable, a suit-able terminating resistor must be fitted into thesocket of the incoming RIO cable. The non-as-signed plug must then be covered with a protec-tive cap.
VIFB8 – 02 4. Installation

Proceed as follows:
1. Connect the wires of the resistor together withthose of the incoming RIO cable between thewires S+ (pin 1) and S- (pin 3) of the sen-sor/RIO cable socket (see following figure).
To guarantee more reliable contact, we re-commend that the wires of the resistor andthose of the incoming RIO cable be crimpedtogether in common cable end sleeves.
2. Fit the sensor/RIO cable socket onto one ofthe plugs on the RIO node.
3. Cover the non-used plug with a protectivecap.

Outputs of valve locations
The outputs for the valves correspond to thevalve solenoid coils. They can only be used inthe intended form.In general the following applies:
• Outputs are not short-circuit protected• Two outputs per valve location• With unilaterally-operated valves the output
with the even bit number is used. The otheroutput cannot be used for other purposes.
Additional outputs
There are two additional outputs (O0.00 andO0.01) on the valve-sensor coupling unit of thevalve sensor terminal. These additional outputsare transistor outputs with positive logic (PNPoutputs).

COMMISSIONING
Configuring the programmable controller
Before commissioning or programming, the usershould compile a configuration list of the con-nected RIO slaves. On the basis of this list hecan:
• make a comparison between the ACTUALand NOMINAL configurations in order to eli-minate connection faults.
• access specifications during a syntax checkof a program in order to avoid addressing er-rors.

Allen-Bradley
If the valve terminal/valve sensor terminal isused on the Allen-Bradley RIO link the followingmust be observed:
• ConfigurationThe valve terminal/valve sensor terminal re-acts on the Allen-Bradley RIO link like a re-mote I/O block from Allen-Bradley. This corre-sponds to a quarter rack in A-B terminologywith a maximum of 32 inputs and 32 outputs.A special configuration software is notnecessary.
• The valve terminal evaluates only the outputinformation.
• The valve sensor terminal evaluates both out-put and input information.
Some versions of A-B programmable controllersrequire the RIO devices to be added on to a"scan list".Please consult A-B literature.

Switching on the operating voltage
Please note: The user should also consult the switching oninstructions in the A-B programmable control-ler manual.
When the controller is switched on, it may auto-matically make a comparison between the AC-TUAL and NOMINAL configurations. For thisconfiguration comparison it is important that theprogrammable controller and the connected RIOslaves are switched on either at the same timeor in the correct sequence.
• Common power supply: If the control system and valve terminal/valvesensor terminal are supplied with power froma common source, the devices should beswitched on simultaneously by means of acentral switch.
• Separate power supply: If the control system and valve terminal/valvesensor terminal are supplied with power fromseparate sources, the devices should be swit-ched on in the following sequence:
1. Switch on the supply to the valve termi-nal/ valve sensor terminal.
2. Switch on the supply to the control system.
If the controller detects a discrepancy betweenthe ACTUAL and NOMINAL configuration, theprogrammable controller reacts as follows:– the red LED lights up.

Diagnosis
The following error states are recognized on thevalve terminal/valve sensor terminal and com-municated to the programmable controller.
In accordance with the RIO protocol, this diag-nostic information is transmitted as commonerror to the programmable controller where it canbe analysed with the status bits.
Diagnostic information
Meaning Cause
Vvalve (Vval) Monitors the operating voltageof valves and additional outputs
Operating voltage at pin 2 ofoperating voltage connection< 21.6V
Voutput (Vout) Monitors the operating voltageof the valves andadditional outputs (no voltage, e.g.EMERGENCY OFF).
Operating voltage at pin 2 ofoperating voltageconnection < 10V
Vinput (Vinp) Monitors the operating voltageof the inputs/sensors withvalve sensor terminals
Operating voltage of sensors < 10V at pin 1(e.g. internal fuse triggered)
SA0 Monitors additional outputO0.00 of valve sensor terminal
Short circuit or overload
SA1 Monitors additional outputO0.01 of valve sensor terminal
Short circuit or overload

Testing the valves and additional outputs
You thereby avoid:
• uncontrolled movement of loose hoses.
• undesired movement of the connectedactuators.
• undefined switching states of the electroniccomponents.
WARNINGBefore the test is started the following mustbe switched off or disconnected:• compressed air supply • operating voltage supply for outputs• operating voltage supply to relay boards

The valve terminal/valve sensor terminal offersthe following test routines with which all outputsare switched on and off cyclically:
Starting the test routine:
If errors occur when the test routine is started,the red LED on the RIO node will blink quickly.The process must then be repeated.
1. Switch off the operating voltage supply of thevalve terminal/valve sensor terminal.
2. Open the RIO node.
3. Note the positions of the address selectorswitch and of the DIL switch elements.
4. Set address 99 and set DIL switch elements1 ... 4 at OFF.
5. Switch on the operating voltage.
6. Set the desired test routine on the address selector switches as follows:
7. Start: set DIL switch elements 1 ad 2 at ON.
Test routine Meaning
Parallel All outputs are switched on/off simultaneously in one-second pulses.
Serial All outputs are switched on/off one after the other in one-second pulses.

Stopping the test routine:
1. Switch off the operating voltage supply of thevalve terminal/valve sensor terminal.
2. Set the address selector switch and the DILswitch elements to their original positions.
Reaction during faults
The outputs are switched off in the followingcases:
• during transmission errors• if the controller is set at position "Program
mode" with a key
• if there is a cable fractureThe outputs are switched off after a delay de-pending on the baud rate set.

Short circuit/overload at the additional output
If there is a short circuit or overload:
• the additional output will be switched off,• the status of the status bits will be set at
logic 1.
In order to activate the output again, the follow-ing procedure should be adopted:
If the short circuit has still not been eliminated,the additional output will be switched off again.
Step Explanation
Eliminate short circuit or overload
Set additional output at 0 (RESET) • Manual (on-line operation, test system)• Automatic in controller program
Set additional output at 1 The status bits I1.14 and I1.15 of the valve sensor terminal are reset at logic 0.
