9.4 System redundancy S2
A redundant layout with two automation systems is necessary for processes that are in
continuous operation. If one system fails the second system guarantees continued,
uninterrupted operation. The measuring device supports S2 system redundancy and can
communicate with both automation systems simultaneously.
