Analog Output Saturated. The analog and digital outputs for the Primary Variable are beyond their limits
and no longer represent the true applied process.
Analog Output Current Fixed. The analog and digital outputs for the Primary Variable are held at
the requested value. They will not respond to the applied process.
Additional Status Available. More status information is available than can be returned in the Field Device
