Dimensionless number = PID control result; selection of assignment to
analogue outputs (O12 – O16, PWM or 0-10 V control, e.g. of
electronic pumps)
Differential between the actual value and the set value of the control
method that currently 'wins out'
Absolute value contrl
active
Status ON if absolute value control is active
Differential control active
Status ON if differential control is active
Status ON if event control is active
Status ON if the correcting variable is > 0
➢ With Enable OFF the correcting variable is zero
➢ If all control modes are switched off, the maximum correcting variable is always issued.
➢ If absolute value control and differential control are active simultaneously, the lower
correcting variable from the two methods 'wins out'.
➢ If two or more PID controls act on an output simultaneously, the higher correcting variable
'wins out'.
➢ As an output variable, the correcting variable is also available to other functions.
