Hello friends.
In the era of industrialization associated with IoT, automatic temperature control in factories and machines is a necessity for any factory. TK4S is a low-cost and high-quality Autonics temperature controller that is widely used in many factories.
Today plc247.com will guide you to use the Omron CP1H PLC to connect to the E5CC controller via Modbus-RTU. This will help us to store temperature data easily.

Note: If communication distance > 100m, need to use an additional 120Ω resistor
TK4S Modbus-RTU Configuration
Press Mode > PAr.4 (Watch the video below the article for detailed instructions)
+ AdrS: 1 (Address Slave)
+ bPS: 9.6 (Baudrate)
+ Prty: EvEn (Parity Check)
+ StP: 1 (Stop bit)
+ rSy.t: 20 (Response Time)
Register for Control
>>> Set Temperature Address = 0000 (hex) / Func: 06
Register for Monitoring
>>> Temperature Monitoring = 3E8 (hex) / Func: 04
