1. Refer to table 4‐14 for transducer block parameter descriptions and table 4‐25 for AO parameter descriptions.
Status Handling
The AI block only gets Good Non‐Specified Unlimited or Bad Device Failure for status from the transducer. This is
reflected in FIELD_VAL.STATUS [19.1]. PV.STATUS [7.1] is the same as FIELD_VAL.STATUS [19.1]. OUT.STATUS [8.1]
can also reflect Bad, Out of Service in addition to PV.STATUS [7.1] values.
In the STATUS_OPTS [14] parameter, you can select from the following options to control the status handling:
Propagate Fail Forward—If the status from the sensor is Bad, Device failure or Bad, Sensor failure, propogate it to OUT
without generating an alarm. The use of these sub‐status in OUT is determined by this option. Through this option,
you may determine whether alarming (sending out an alert) will be done by the block or propagated downstream for
alarming.

PV_FTIME
Uncertain if in Manual mode—The status of the Output is set to Uncertain when the mode is set to Manual.
Note
1. The instrument must be in Out of Service mode to set the status option.
2. The AI block only supports the Uncertain if in Manual and Propagate failure. Unsupported options are not grayed out; they
appear on the screen in the same manner as supported options.
