The long-term diagnosis of the processor system includes the following events:
Reboot
Changed mode of operation
(INIT, RUN, STOP/VALID CONFIGURATION, STOP/INVALID CONFIGURATION),
Changed program mode of operation
(START, RUN, ERROR, TEST MODE),
Configuration load or deletion
Configuration and reset of switches
Processor system failures
Operating system download
Forcing (setting and resetting the force switch is allowed)
I/O module diagnostics
Power supply and temperature diagnostics
The long-term diagnosis of the communication system includes the following events:
Reboot of the communication system
Changed mode of operation
(INIT, RUN, STOP/VALID CONFIGURATION, STOP/INVALID CONFIGURATION),
User log-in
Operating system load
If the memory for the long term diagnosis is full, all data older than three days is deleted
allowing new entries to be stored. If no data is older than three days, the new entries cannot be
stored and get lost. A message in the long-term diagnosis warns that it was not possible to store
the data.
The short-term diagnosis of the processor system includes the following events:
Processor system diagnostics (setting the force switches and force values)
User program diagnostics (cyclic operation)
Communication diagnostics
Power supply and temperature diagnostics
I/O module diagnostics
The short-term diagnosis of the communication system includes the following events:
safe
ethernet
-related events
Start / stop while writing to the flash memory
Faults that can occur while loading a configuration from the flash memory
Unsuccessful time synchronization between the communication system and the processor
system
Parameter errors associated with the inputs or outputs are possibly not detected during the
code generation. If a parameter error occurs, the message INVALID CONFIG with the error
