If the controller function for the device is enabled and the controller type is configured to two-state con-
troller, all of the settings can also be configured on the device.

Controller parameters

The following table shows the parameters of a parameter block in the case of an activated two-state con-
troller (option). The transmission behavior is specified by the selection of the controller structure and de-
termined by the configuration of the parameters for the proportional band (P component), derivative time
(D component), and reset time (I component).

Relay Type of controller output.
The cycle time is calculated on the basis
of the type of controller output.

No selection Signal (active for rising edge) for starting
and stopping autotuning.
Autotuning is started by a rising edge. If
autotuning is active, it is stopped by a ris-
ing edge.
No selection Signal (high-active) for inhibiting autotun-
ing

Size of the proportional band
The controller structure is not ef-
fective with Xp = 0 (behavior
identical to limit value monitoring
function).
Influences the differential com-
ponent
of the controller output signal.
The greater the derivative time,
the more effect the differential
component has.
Influences the integral compo-
nent
of the controller output signal.
The greater the reset time, the
less effect the integral compo-
nent has.
