Hello everyone, in the previous post thelivingchristmascompany.com guided you to use PLC FX5U to connect with Omron E5CC Controller, today thelivingchristmascompany.com will continue to write a tutorial for you to connect to Autonics Controller TK4S via Modbus RTU.
To be able to communicate using Modbus RTU, we need to choose Model TK4S with RS485, in this project I use TK4S-T4SN.
