Standard Control Keys in PM
I would like to understand the Standard Control Keys available in the System.
Actually I am learning in IDES and the below is what system is showing. Looks not correct.
If anyone can share PM Standard Control Keys available and explain the difference between each of them, it would be good for undrestanding of all.
PM01 Plant maintenance - internal
PM02 Plant maintenance - external
PM03 Plant maintenance - external (services)
PM05 Plant maintenance - internal (service)
PM07 Compatible units - no costs
