FEEDBACK FEATURE
The status of the output can be shown via the
object “Status”. Additionally the value of the
feedback telegram can be inverted.
When the feedback telegram is enabled, the status
information is transmitted every time that a change
occurs on the output. However, it is also possible
to define a periodical sending of the status through
the parameter “Feedback Periodical Sending”.
Thereby, the current value of the output is
transmitted with the period configured.
Additionally, to reduce the bus traffic after any
failure, a delay for the status feedback transmission
at startup can be parameterized. When this option
is used, the status of the output after a bus voltage
failure is sent once the time delay configured has
elapsed.
The delay configured only affects the
sending of the feedback. The behaviour of
the outputs has no effect and they can
even be switched during the course of the
delay.
BUS VOLTAGE FAILURE
The behaviour of the output during and after bus
voltage failure can be parameterized. The combo
is equipped with bistable relays. That is why the
reaction of the output during bus voltage failure can
be configured too.
The combo actuator allows three different
behaviours for bus voltage failure:
No Reaction/Last State: The relay of the output has
no reaction and remains the last state received.
ON: The relay is closed.
OFF: The relay is opened.
