Hi!
I have little experience with Modbus but I coinfigured the Siemens LOGO as Modbus server and tried to get information using simplymodbus tcp client. I used port 502 since I believed that this is the correct one? In the siemens logo software it say that the server is on port 502, but after a while of testing I tried with Simplymodbus on port 510 instead and that worked. Despite that the siemens logo is configured for port 502?
