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.

Description
Behavior when the local bus watchdog is
triggered ("Local bus communication
faulty"):
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.
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.
The output stage of the channel switches
off; the output becomes high-ohm.
A specified output value (parameter: User
substitute value) is written to the output
stage. (Value setting = "process value")
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.
