Use Fault State value on Restart—Use the value of FSTATE_VAL [24] for SP [8] when power is restored or if the device is
restarted, otherwise use the last value saved in non‐volatile memory. This does not act like Fault State, it only uses the
value of FSTATE_VAL [24].
Fault State to Value—The output action to take when a fault occurs (if not selected, use hold last value; if selected, use
FSTATE_VAL [24]).
Increase to Close—If the Increase to Close bit is set the value to the transducer is inverted, e.g. 20% becomes 80%.
SP-PV Track in Man—Permits the setpoint to track the process variable when the target mode of the block is MAN.
SP-PV Track in LO or IMan—Permits the setpoint to track the process variable when the actual mode of the block is LO
or IMan.
SP Track retained Target—Permits the setpoint to track the RCas or Cas parameter based on the retained target mode
when the actual mode of the block is LO or Man. When SP‐PV track options are enabled, the SP Track retained target
will have precedence in the selection of the value to track when the actual mode is Man and LO.
Simulation
When simulate is active, the transducer sub‐parameters show the actual transducer block status and value as normally
passed back to the AO block. The Simulate sub‐parameters are writable and replace actual transducer values.
Note
When simulate is active, the output block no longer writes values to the transducer block. If the Output Blk Timeout period is
exceeded, the transducer block may move the valve to the Zero Power Condition depending on the configuration of the Output
Block Timeout Alert.
Application Information
The configuration of an AO function block and its associated output channels depends on the specific application. A
typical configuration for the Analog Output involves the following attributes:
PV_SCALE
BKCAL_OUT
IO_OPTS
SHED_OPT
Set the range and engineering units to values that correspond to the operation range.
For the digital valve controller, PV_SCALE [11] is typically set between 0 and 100%.
If you are using the CAS_IN [17] connector wired from another block, wire the
BKCAL_OUT [25] attribute to the other block's BKCAL_IN [27] attribute.
Set the type of tracking and action upon fault state.
Set the action to be taken when the set point or output are not updated in a remote
mode.
