How time stamping functions in the redundant system
Both IM°152 save the messages of the time-stamped signals. After a changeover from the
active to the passive IM 152 the "new" active IM 152 can relay the current messages to WinCC.
During the switch between the two IM 152 the signal changes are not time-stamped. In WinCC
you can recognize in which time span not time stamping occurred.
