  1. @ElectronGuru We tested the communication failure by removing the ethernet cable. The variables really do freeze. So now we know for sure!
  2. Hello! I have one Controlllogix project that communicates with a modbus slave through modbus TCP, using a Prosoft module model MVI56-MNETR. Does anyone know what happens to the data polled in case the network fails? Do all variables go to zero or do they freeze in their last value (or something else entirely)? I couldn't find anything in the Prosoft manual. Thanks for any help!
  3. @ElectronGuru thank you so much for the info! I would also bet that the data freezes. I will propose a short program to check for communication failure in order to take the appropriate response. If I manage to test the situation I will come back here and report.
