User MODBUS
Users can define Modbus registers from 42873 to 43000. Values, setpoints and Alarm states can be
specified for these new Modbus registers to prepare the Modbus protocol for batch reading and writing or to
standardize Modbus protocol between FW versions or branches.

Analog Input Sensors and User Sensors
Controller and/or some extension modules allow connection of sensor outputs to Analog Inputs. There is
whole variety of common sensor output characteristics prepared in configuration by default. Although if there
is sensor that is not in the list, it is possible to prepare custom characteristics (up to 16) with up to 31
definition points.
