Hi,friends.
If change the bad one of the redundance,do the deltaV need to be downdoaded the changed part? the redundant controller,the redundant I/O module and the redundant SIS module is the same or what's their difference? I need to hear your experience.
Check SW, if differ - upgrade
In reply to Roman Kostuniak:
If SW is the same,changing the redundant module(controller,I/O,SIS) don't need to download,can the modules still be synchronous?thanks.
In reply to Leo He:
don't need, even if differ
