9 -2 -1. Communication wiring to PLC

A. Remote I/O ( EX500 - GAB1 -X1 ) communication wiring

Remote I/O communication cable can be connected with any of the two M12, 4 pin connectors on GW Unit. ( Refer to section 4 -2 )

For pin out of M12 connector refer to section 3 -2.

Communication system has two connectors on the GW Unit and they are connected together inside the unit, therefore, either one of them can be use to connecting a PLC with the GW Unit and second one could be used for daisy chaining another GW Unit.

It is recommended to use SMC specified cable to connect a PLC with GW Unit. ( Refer to section 3 -6 -1 ) Rockwell Automation specified Remote I/O cable can be used too.

！CAUTION

1.If more than 1 GW Units are desired in the system, connect the units together one by one using a communication cable.

2.Set the terminating resistance at the last GW Unit. ( Refer to section 4 -4 -3 for detail )

3.Use the Water Proof Cap on an unused Communication connector. ( Refer to section 3 -6 -5 )

B. DeviceNet ( EX500 - GDN1 ) communication wiring

Communication between a DeviceNet GW Unit and PLC is accomplished through a M12, 5 pin connector. Refer to section 5 -2 for detail. For pin out of this connector refer to section 3 -2.

It is recommended to use SMC specified Communication Connector Cable. ( Refer to section 3 -6 -1 for detail )

！CAUTION

1.Follow the communication cable specification. ( Refer to section 5 -1 )

2.Use a terminal resistor at both ends of main truck line to absorb the reflection. ( Refer to section 5 -1 )

C. PROFIBUS-DP ( EX500 - GPR1 ) communication wiring

Communication between a PROFIBUS-DP GW Unit and PLC is accomplished through a M12, 5 pin connector. Refer to section 6 -2 for detail. For pin out of this connector refer to section 3 -2.

Be careful to wire the communication connector for PROFIBUS-DP, because there are for input and for output.

！CAUTION

1.Follow the communication cable specification. ( Refer to section 6 -1 )

2.It is necessary to set the terminating resistance to the units located at the ends of transmission line. ( Refer to section 6 -4 -2 )

9 -2 -2. Communication wiring to the SI Unit and the Input Unit

GW Unit is connected with SI Unit or the Input Unit through a M12, 8pin connector. Refer to sections 4 -2, 5 -2, 6 -2, 7 -1, 8 -1 for detail.

For pin out of this 8pin connector refer to sections 3 -2, 3 -3 -2, 3 -4.

Refer to section 3 -6 -2 for Cable part number to connect a GW Unit with SI Unit or Input Unit.

！CAUTION

If Input Unit Manifold is not connected with the SI Unit, a Terminal Plug should be hooked up with port C1 ( for SV series valve manifold ) or port 0 ( for VQC series valve manifold ). Without this plug COM LED on the GW Unit will not light up. ( Refer to section 3 -6 -4 )
