Hello,
I'm dealing with a strange problem when trying to read tags from a S7-300 PLC.
This is our configuration:
When I'm trying to read something from the PLC I'm getting this error: 'Received 12 bytes: '32-02-00-00-00-00-00-00-00-00-00-00', expected 20 bytes.'
If I'm connecting to the PLC by MPI network, everything works as expected.
Any ideas what could cause the problem?
