[darren221170]

Hello all, I had a sf fault on a s7 plc. I turned off the plc pulled out the mcc card and did a reset. I then put the mcc card back and reloaded it to plc.Now i have no communication with the hmi.please help!

sounds like your network settings are not there since you reset the plc..netpro etc

Does your io work? this is the hardware config

do you have the original project and siemens plc programmer etc, if you do u could reload it or recreate it if needed

Has this cured your sf fault ?

Yes i can see all the blocks on the plc,i can even see the hmi on the network and yes resetting it cured the original sf fault. It's a micro innovations hmi i think maybe the problem is with this?
