Hello, Automatic temperature collection and monitoring is a necessity of most factories today, Autonics TK4S temperature controller is also integrated with RS485 for Industrial Communication.
Today plc247.com will guide you to use PLC Keyence KV5500 (or KV3000, KV5000, KV7000 Series, KV 8000 Series…) in combination with Module KV-L21V to connect, monitor and control Autonics TK4S through Modbus RTU.

Note: A 120Ω terminal resistor should be used if the communication distance between PLC and Autonics TK4S is long distance.
Autonics TK4S Modbus-RTU Configuration
To be able to control Autonics TK4S with Modbus RTU we need to set the following communication parameters

Hi, just to know, do we need to add resistor 120 ohm at the end unit?
If the communication distance is long, it will need
Hi, how many units of TK4S we can link? is it by adding $3 to DM10101 for the 3rd unit?
yes sir
