Samkoon HMI “Modbus RTU” Omron E5CC Tutorial

Written by

Hello everyone, automatic temperature control and storage is an increasingly necessary need for any factory. The Omron E5CC controller has Modbus Modbus-RTU support for this. That’s why today guides you to use Samkoon HMI to connect and control it.

The HMI model used is Samkoon SK-070HS and uses the COM.0 port (Other HMI models are similar). You must pay attention to choose Model Omron E5CC with RS485 support, uses Model “E5CC-RX2ASM-802”.

Omron E5CC Modbus Parameters Setting

To be able to control and monitor Omron E5CC via Modbus-RTU protocol, we need to set the following parameters:

Omron E5CC Registers Address

>>> Temperature Setting Address = 2103 (hex) = 8451 (dec)

>>> Temperature Monitoring Address = 2000 (hex) = 8192 (dec)
