Caution
When installing the CP for use as a PROFINET IO controller, note the following
points about the power supply:
When using the CP in the central rack or in a universal rack operating as central
rack, you should not insert or remove the CP when the power is on. If you remove
the CP when the power supply is on, the CPU changes to STOP and indicates
