Hello, I am using a SEN0246 ultrasonic sensor from the DFROBOT brand and I wanted to use it with the OPTA PLC, this sensor works through the RS485 protocol, but I can't find how I could test it, in the manuals I see that there are tutorials on communication between two OPTA PLC devices. RS485, but not how it is used with a sensor, can you help me with this topic?
