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 plc247.com 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, plc247.com 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)
