Hello everyone, in the previous post plc247.com guided you to use Mitsubishi’s FX3U to control Read/Write data to Omron’s E5CC temperature controller.
Today I would like to continue to guide you to use Omron’s own PLC to control E5CC via Modbus RTU communication. The project uses PLC CP1H (combined with Module CP1W-CIF12 (or CP1W-CIF11)
Connection diagram CP1W-CIF12 with E5CC
If communication distance is far, we should use 120Ω end resistor
E5CC – Communication Specification Configuration
In the project I use 2 E5CC should set the parameters as follows:
+ CN E (Controll Mode) = 6
+ U No ( Slave Number) = 1 (Slave #1) = 2 (Slave #2)
+ bPS (Baud Rate) = 9.6 (9600)
+ Prty (Parity Check)= EVEN
+ Stop bit = 1

+ E5CC SV Write Command
+ E5CC Read PV Command
+ Read Data Reponse

If you have any problems connecting E5CC with PLC CP1H, please comment below the article, plc247.com will reply to you as soon as I read it.
Thanks and Best Regards!
