Hello,
I want to write a MPI-driver in Delphi to communicate with a Siemens S7 plc. However, I can't find anything about the MPI frame and/or protocol. Does anybody has information how this works or where I can find this?
Regards,
S. Olinga
P.S. In the past, I already wrote an unitelway driver for the Modicon TSX 37/57. So if anybody needs some information about this?
