Commissioning > Notes on commissioning
WARNING
Safety function only ensured after validation
−
The planned safety function of the plant/machine is only ensured after
validation.
WARNING
Organizational or technical measures required for compensation of the CRC
checksum
Take technical or organisational measures to ensure that the correct project
for the application is started in the CPU by comparing the CRC checksum:
‘Comparison of the checksums’...page 123
−
After transferring a project to the CPU.
−
A valid but incorrect project for the application could be loaded.
−
After removing the SD card.
−
There could be a valid project in the internal memory but the incorrect
one for the application.
−
After inserting or changing the SD card.
−
There could be a valid project on the SD card but the incorrect one for
the application.
If you use a technical measure to check the CRC checksum, it must be
implemented in such a way that the check done by a third technical instance
outside the safety CPU.
WARNING
Safety and availability of the plant/machine
−
Ensure the safety and availability of your plant/machine by selecting the
appropriate watchdog time FSoE_WD_Time.
−
Select the watchdog time high enough so that the safety of your plant/
machine is still guaranteed with the highest possible availability.
WARNING
Avoid danger caused by triggering the safety function too late
−
Ensure that the maximum permissible values TI
FSoEWD_MAX
and
TO
FSoEWD_MAX
are not exceeded.
WARNING
Debug operation
−
Switching to debug operation means leaving normal operation.
−
Make sure that your plant/machine does not pose any danger to people
during debug operation and that no damage can be caused.
NOTICE
Acclimatization before start-up
Make sure that commissioning only takes place after the CPU and the associ-
ated modules have acclimatized!
