Termination Resistor
The RS-485 bus is terminated with 120 Ω termination resistors in both ends. NXL has a built-in
termination resistor which is switched off as a default. See the jumper selections in chapter 6.2.5.1

Modbus address area
The Modbus bus of NXL uses the ID numbers of the application as addresses. The ID numbers can
be found in the parameter tables of the Application manual.
When several parameters/monitoring values are read at a time they must be consecutive. 11
addresses can be read and the addresses can be parameters or monitoring values.

Modbus process data
Process data is an address area for fieldbus control. Fieldbus control is active when the value of
parameter 3.1 (Control place) is 2 (=fieldbus). The contents of the process data has been
determined in the application. The following tables present the process data contents in the Multi-
Control Application.
