Refresh counter for process values
Measured values are calculated every 10 ms in the SIWAREX module. A counter is

zero. The counter can be used as a time stamp for data record DR 31.

DR 32 Message display
Data record 32 indicates all pending message bits. The bit "Error status changed" is present in
the status bits of the DR30. If this bit is set, the message area of the DR32 has been changed.
The DR32 indicates which message has been newly added or deleted. The data record is
automatically read by the SIMATIC FB in the event of an error. Following successful reading,
the status bit is reset in DR30.
