Written by plc247.com

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.
