Schneider Electric M238 PLC

2 posts in this topic

Hello everyone, we have started to use a new Schneider PLC M238 and we have some problems with Modbus communication. We are reading holding registers (%MW49=400050) and writing to this modbus register. This work's OK. Now we need to write a coil. On the M340 this was done like this: %M100= modbus register 000101. How can we write a single coil to the M238? best regards
