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.
