Operating status monitoring is optional and monitors only blocks in a Switched on state. If a referenced
block is found to be switched off during active operating state monitoring, but that the block should have
been in the state Switched on, a process alarm is generated and the plant operating mode changes to
exception value [EcptVal].
The momentary alarm state is visible from the state flag [StaFlg].
Monitoring is active from the point when the corresponding sequence successfully completes the switch on
process, that is, the process value for block [PrVal] is not equal to Off and the transient state is completed
[TraSta] = No.
The [PrVal] of the block will be monitored. Hence, only those events which affect [PrVal] can be detected,
that is:
● Local fault shut down using interconnection of fault [Dstb] to enable safety, manual [EnSfty].
● Local shut down of the block in a higher priority application program.
● Switch-off by manual operation of the output module if the I/O module returns the manual setting
value.
● Block switched off via HMI operation or manual switch in control panel
Command control is only in a position to recognize fault-related deviations and act accordingly when the
interconnection of all relevant faults [Dstb] occur locally on a monitored output of value block to [EnSfty].
Its default value [DefVal] becomes the process value [PrVal], if a referenced output or value block is out of
