Modbus Switches
The “Modbus Switches” contains of two groups of LBOs named “ModbusSw1” and “ModbusSw2”. Both
registers are available on Modbus for simple writing (using command 6 or 16). The particular bits of these
registers are available as binary status for universal use in logical binary outputs of the controller as
“ModbusSw1..ModbusSw32”. No password is required for writing of those registers. There are two Values
“ModbusSw1” and “ModbusSw2” in group “Log Bout” available for back-reading.

:
The LSB of ModbusSw1 (46337) cor
responds with LBO “ModbusSw1”
The LSB of ModbusSw2 (46338) cor
responds with LBO “ModbusSw17”
The Values ModbusSw1 and ModbusSw2 have the position of LSB opposite-wise.

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.

There is “electronic” type of sensor available for Shared Analog Inputs which can be used to interpret shared
data over CAN bus.
