IO_OPTS and STATUS_OPTS
These parameters stipulate options about the block’s signal processing and mode
transitions. The settings of these options are made by setting or resetting the respective
bits: on = true, off = false. Table 37 shows the options available in AO block IO_OPTS.
Only the Propagate Fault Backward option is available in AO block STATUS_OPTS.
Table 37 IO_OPTS of AO Block
Bit Meaning Description
1 SP tracks PV if Man Equalizes SP to PV when target is MAN mode.
3 SP tracks PV if LO Equalizes SP to PV in LO mode.
4
SP tracks RCas or Cas if LO
or Man
(SP track retained target)
In LO mode, Equalizes SP to RCAS_IN if target mode is RCas
and to CAS_IN if target mode is Cas.
5 Increase to close Inverts the signal while it goes from SP through OUT.
6
Faultstate Type
(Faultstate to value)
Uses a FSTATE_VALUE in LO mode.
7
Faultstate Type
(Use Faultstate value on

Uses a value preset for fault state also at a restart.
8 Target to Man Sets the target mode to Man upon activation of the fault state.
9 PV for BKCAL_OUT Sets the value of PV in BKCAL_OUT and RCAS_OUT.

Bit Meaning Description
4
Propagate Fault Backward Stipulates the handling of the value, data status and related
alarm of BKCAL_OUT and RCAS_OUT to be performed.
If this option is true, then:
❑ Set the quality and sub-status components of the status of
BKCAL_OUT to Bad and sensor failure, respectively.
❑ Do nothing for the BKCAL_OUT value.
If this option is false, then:
❑ Set the quality and sub-status components of the status of
BKCAL_OUT to Bad and non specific, respectively.
❑ Generates a block alarm.
