Re: [?]: change plc1 to plc2 have problem ?
hello, i often use this configuration and all working fine.
I think that you use a IM153.2 for et200. The error is only into monitoring system or is real ? --> red led active on IM153 and or red led on cpu )
In any case which bit you reset from monitoring system ? Which OB's do you use to check the problem ?
my suggest in this case is : clear complete both cpu and reload all !! sometimes i have had strange problem. With reload procedure, i have resolve
