Note
Restriction during testing with breakpoints
•
When you test with breakpoints, there is a risk of overwriting the cycle time of the CPU.
If you are using technology objects and test them with breakpoints, the CPU switches to
STOP mode.
Note
F-System SIMATIC Safety
The setting of breakpoints in the
standard user program results in errors in the
Sequence of F cycle time monitoring
Error in communication with the fail-safe I/O
Error during safety-oriented CPU-CPU communication
Internal CPU error
If you still wish to use breakpoints for testing, you must deactivate
the safety mode beforehand. This will res
ult in the following errors:
Error in communication with the fail-safe I/O
Error during safety-oriented CPU-CPU communication
