Hi, some day ago the lights on the panel just shut down. I disconnected the panel to test it and when I turn it on the light was just fine (very stange). SoI connected the panel again, thats where the problem begin. All the input/output fields appeared like this #####. I think that the port was damaged but make a backup with protool. The hmi is connected to the s7-200 cpu with a MPI cable, I get connected to the cpu and check baut rate, the 2 ports have 19.2kb. In HMI the serial channel is enable and the mpi channel is disable.When I connect the mpi cable no message of establishing connection of panel. If connection to plc is through PPI, serial channel should be enable??What´s happening????

Before disconnecting the panel all the fields were with numeric values, connection was fine.

Thanks.
