LoopUpdateTooFast
The LoopUpdateTooFast flag is set by the PID algorithm when the PID
update is not executed cause of the PLC scan time limitation.
To solve this, speed down the PID loop control or use PIT interrupt.
ProcessValueInDeadBand
The ProcessValueInDeadBand bit is set when the PV(Process Value) is within
the Zero-Crossing Deadband range.
ZeroCrossingDeadband
The deadband extends above and below the setpoint by the value entered and
is entered at the zero crossing of the process variable and the setpoint.
This means that the deadband is in effect only after the process variable enters
the deadband and passes through the setpoint.
The valid range is 0 to the scaled maximum, or 0 to 16,383 when no scaling
exists.
