Hi, sure you can turn off the M580 plc and replace the DRA card. Then turn on the plc and it will starts normally.

In case you set the cold start of the PLC - the PLC will lost all current values and load the initial values.

 

You can also remove connector from DRA card during PLC is in RUN. Then replace the DRA card and put the connector back without to stop or turn off the PLC.
