Note
To increase service of life of your relays and to protect your modules from reverse voltage damages, externally
connect a clamping diode in parallel with each inductive DC load or externally connect an RC snubber circuit in
parallel with each inductive AC load.

Communication Channels
The CPU-700-C3 has 3 communication channels that supply the user with 3 independent channels
(ports) identified as P1 (EIA-232), P2 (EIA-485) and P3 (EIA-485).
All of the 3 channels can be used at the same time with the following features:
¨ P1 (RS-232- C) is for programming and monitoring, point-to-point short connections.
¨ P2/P3 (RS-485) is for programming and monitoring, point-to-point or multi-drop in long distance
industrial connections.
¨ Any of the ports can be connected to the ENET-700/ENET-710 (Ethernet/Serial) converter
module.
In one Network it is possible to have up to 31 CPU-700 modules. In order to make the correct
communication, each CPU-700 module must have an unique MODBUS ID (address) and a
baudrate for P1 (Modbus) and other baudrate for P2 and P3 (Modbus). Modbus baudrates are
configurable by software throughout the use of CONF700.
