The Error for the PID loop is the magni-
tude (absolute value) of the difference
between the Setpoint (desired value) and
Process Variable (actual value). The PID
output deviation signal [OD] (output
terminal function option code 04)
indicates when the error magnitude has
exceeded a magnitude you define.
