•Do not route network wires with power wires.
•Connect one Ethernet cable per controller to a 10/100 mbps ether- net switch. Both Mod- bus TCP and Ether- Net/IP™ are available on the network.
•A RUI may be con- nected at the same time using Slot C.

Adjacent terminals may be labeled differently, depending on the model number.
Note:
To prevent damage to the controller, do not connect wires to unused terminals.
Wiring a Serial EIA-485 Network
Do not route network wires with power wires. Connect network wires in
A termination resistor may be re-
quired. Place a 120 Ω resistor across T+/R+ and
Only one protocol per port is available at a time: either Modbus RTU or Standard Bus.
Note:
Maintain electrical isolation between analog input 1, digital
Note:
The control output common terminal and the digital common terminal are referenced to different voltages and must remain isolated.
Note:
Avoid continuous writes within loops. Excessive writes to EEPROM will cause premature EEPROM failure. The EEPROM is rated for 1,000,000 writes.
