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.
Register for writing Modbus register number
ModbusSw1 46337
ModbusSw2 46338
N :
OTE
The LSB of ModbusSw1 (46337) corresponds with LBO "ModbusSw1"
The LSB of ModbusSw2 (46338) corresponds with LBO "ModbusSw17"
The Values ModbusSw1 and ModbusSw2 have the position of LSB opposite-wise.

Power Formats

IGS-NT family allows user to choose from several Power Formats that affect dimensions in which values and
some setpoints are interpreted or adjusted. Power formats may be changed in Miscellaneous tab in
GenConfig. There are following Power Formats available:

1 kW kVAr kVA kX V

0,1 kW kVAr kVA kX V

0,01 MW MVAr MVA MX kV

0,01 MW MVAr MVA MX V
N :
OTE
Range of some setpoints and values is changed significantly when different Power Formats are selected.
Last Power Format is designed to be used in combined Power/High Voltage and Low Voltage instalations.
High voltage is then interpreted in Volts (e.g. 33256V instead of 33kV).
Last two Power Formats can be used in combination on one CAN bus.
