In the Redundant System
The IM 153-2 also supports the time stamp function in the redundant S7-400H
system.
Time Stamping Signal Changes in a S7-400H
The two IM 153-2 modules store the messages of the time-stamped signals. This
makes it possible, after a switchover operation from the active to passive IM 153-2,
for the new active IM 153-2 to forward the current messages to WinCC.
Note: During switchover between the two IM 153-2, signal changes are not time
stamped. You can see in WinCC when time stamping hasnt taken place.
You can find further information on time stamping in redundant systems in the
PCS 7 documentation.
