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

+ Transmission Distribution
+ 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!
Hello such a great tutorial, it’s just that I encounter with a problem in which my RS485 “comm” light didn’t light up.
Do you happen to know why? 🙏🏻🥲😅
need folow video sir
What is the password ican’t open the pdf file
password: plc247.com
dear sir can not working this password
password: plc247.com
This password is not working, why use password anyway?
using winrar v5.5 or higher
when use RDA- , RDB+, ?
WHEN USE SDA-, SDB+?
same sir
Hi, do you have example communication between CP1L,E5CC and PROFACE HMI? CP1L to E5CC use ModBus.. CP1L to PROFACE HMI use ethernet.. thank you.
easy sir. you can make them project
I can’t writing the data to the registers.
The reading has been corrected and it works.
What could be the reason for this?
you settings parameters for E5CC Correcly ?
All just like in the movie.
