Split from IO access error in S7 -1200 CPU.

Hello,

TJ Matthew

This is my bad, I forget to turn off the power of CPU/any module while connecting new additional DI DQ module s7-1200. This mean i slide the connector when the PLC in running mode. The new additional module have RED LED blinking (just one led blinking). Is that the module short circuit? Can i still use the module? Or the module have safety protection for my case? I really need ur answer please

no other way as do cfg with HW as it need to be, Compile HW and download to PLC. Turn power OFF and ON and you'll see. If some diag is still red, run Diagnostic and check what is wrong.
