EX500 Serial System
9 -2. Communication wiring
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 )
