Testing with breakpoints is not used.
No SYNCUP is performed during testing with breakpoints. You will find more information
on testing with breakpoints in the STEP7 online help.
SYNCUP system state
Synchronization in the SYNCUP system state ensures that the two CPUs can operate
redundantly. With the SYNCUP system state, the redundant system switches from RUN-Solo
to the RUN-Redundant system state. Afterwards, both CPUs synchronously process the same
user program.
Starting SYNCUP
The initial situation is the RUN-Solo system state. The primary CPU of a redundant system is in
the RUN operating state and the backup CPU is in the STOP operating state.
The operating states are shown on the displays:

Start SYNCUP by:
•
Starting the backup CPU via the PG/PC/HMI device or the display, and the mode selector is
set to RUN.
or
•
Switching the mode selector on the backup CPU from STOP to RUN.
or
•
Powering on the backup CPU (mode selector to RUN).
