Obey SP limits if Cas or Rcas
Normally the setpoint will not be restricted to the setpoint limits except when entered by a human
interface device. However, if this option is selected, the setpoint will be restricted to the setpoint
absolute limits in the Cas and Rcas modes.
No OUT limits in Manual
Do not apply OUT_HI_LIM or OUT_LO_LIM when target and actual mode are Man. Trust the
operator to do the right thing.

IFS if BAD IN
Set Initiate Fault State status in the OUT parameter if the status of the IN parameter is BAD.
IFS if BAD CAS_IN
Set Initiate Fault State status in the OUT parameter if the status of the CAS_IN parameter is BAD.
Use Uncertain as Good
If the status of the IN parameter is Uncertain, treat it as Good. Otherwise, treat it as BAD.
Propagate Fail Forward
If the status from the sensor is Bad, Device failure or Bad, Sensor failure, propagate it to OUT
without generating an alarm. The use of these sub-status in OUT is determined by this option.
Through this option, the user may determine whether alarming (sending of an alert) will be done by
the block or propagated downstream for alarming.
