Plc engineer Posts: 34 Rating: (0)	Hi Guys, I have been working on S7-400H system wd CPU417-4H.I posted this thread before but couldn't have exact answer.I wana take some decision in STEP-7 on the basis of which CPU is Master?and which CPU is Standby??i mean something like that if CPU0 is master a particular bit should be set and if CPU1 is master it should be reset. I have a document which shows that i can have information abt CPU if i use FB523.But i couldn't find FB523 anywhere in Library....I dont want to use CFC also. Can anybody help me?? Thanks PLC Engineer
