Communication interfaces: Setting and function
For the transfer of analogue signal values to setpoints, only the transfer ramp is now
defined. For this purpose, the minimum and maximum support points of the character-
istic curve are specified and the respective setpoints are amended (MIN signal/value as-
signment and MAX signal/value assignment).
Min signal/value assignment

When all signal/value assignments have been performed, the setting of the analogue
setpoint source is completed.
An editor for adjusting the substitute setpoint in the event of a cable break or wrong
configuration of the analogue input will open.
