Read Data Register of Mitsubishi PLC A and Q Series

[winstonlorenzo]

Hi everyone,

I have a problem which I need to read the Data Register (DM) of a Mitsubishi PLC (Q and A Series) via UDP. I need to make a code in C Language that will be using low level socket programming to read the DM. Does anyone here knows what are the command message that i need to send to the PLC?
