Proface GP2400 to Siemens S7-200

Has anyone has any success connecting a Proface GP2400 to
a Siemens S7-200 via MPI. If you look in the driver list for the
Proface there is only a driver for the S7-300 and the addressing
seems to be slightly different, Thanks.

Usually you will need a PPI driver to connect a third party HMI to S7200. Sometimes you can get away with using the MPI driver but this is not to be recommended. The S7200 can connect to other devices using MPI but it uses an MPI emulator that doesn't include the full MPI protocol.

Depending on the software version you can select S7-200 via MPI.
