Testing Modbus Plus networks


Thread Starter

Do you know if there are other software tools available other than DOS 'MBPSTAT' to test MODBUS PLUS networks? I've looked at the Modbus protocol and decided it was possible to write a windows program, but I can't be the first to think about this (reinventing the wheel).

Look at the files on the driver disk that came with your Modicon MB+ card.

It should have C library files. I haven't used them myself, but I imagine you may find something useful in them.
