Communication
6.5 Communication via PROFINET
CAUTION
Shutdown on faults can only take place if both monitoring functions are activated!
When the PROFINET interface is in operation, parameter P8840 should also be set to a
value of > 0. The process data monitoring function is thus activated/deactivated solely using
the PROFIBUS process data monitoring function. The monitoring time then corresponds to
the process data monitoring time setting plus the time set in P8840.
Note
Process data whose complete control word (PZD1) is set to zero are not transferred from the
PROFINET interface to the inverter.
Result: Alarm A0703 and possibly fault F0070.
