    Good day to all!

    We have a S7 PLC in our plant. However when we try to connect our programming device (laptop) the CPU automatically detects a system fault and switch active to its redundant.

    What could be the reason for the SF and how can we connect to the PLC without experiencing the fault?

    Thanks! :)
