Hello, I have a CNG compressor that is run by a PLC. I tried to get team viewer on it to be able to view it remotely, I accidently disabled the ethernet ports causing data loss. I then right clicked on station HMI and pressed use older or previous version. Now when I open station HMI, it is unable to load the mer file and access my compressor settings. I have no knowledge in PLC systems and messed with something out of my range. Is there anything I can do to get back to my settings to be able to run my compressor again? Thanks for any help. It is factorytalk machine edition version 7.00
