Description
Behaviour on
K-Bus timeout
Behavior when the local bus watchdog is
triggered (“Local bus communication
faulty”):
Deactivated
No response from the channel. The output
stage retains its last output value setting.
The local bus “RUN” LED also lights up
green when local bus communication is
faulty.
Hold last output value
The output stage retains its last output
value setting. The local bus “RUN” LED of
the channel goes out when local bus
communication is faulty.
Set output to high-
impedance
*)
The output stage of the channel switches
off; the output becomes high-ohm.
Set output to user
substitute value
A specified output value (parameter: User
substitute value) is written to the output
stage. (Value setting = “process value“)
User
substitute
value
[Input field]
Substitute value relates to the K-Bus
setting “Set output to user substitute
value.”
Note: Scaling/calibration still occurs
before the output stage sets the substitute
value.

7.1.3.3 Scaling
Under the “Scaling” menu item, you can enable and modify the user scaling for
each channel. You select the corresponding channel via the tabs in the
application area.
The manufacturer scaling can be switched on or off, but the gain and offset
values cannot be changed.
