2. DESCRIPTION
FC BACNET GATEWAYS are dedicated for inverters with a communication port Modbus RTU (connected to port RS 485-
2). FC BACNET GATEWAY use port RS 485-1 to connect with main system (BMS, main PLC etc.) by Modbus RTU or
BACnet MS-TP in standard RS-485.
The module with an application that enables the operation of up to 10 LG inverters of the M100 or G100 series. The
application allows you to control and read the parameters of the inverters via BACnet MSTP. Configuration of the module
and control of inverters in accordance with the attached list of BACnet variables.
3. SETTING OF THE COMMUNICATION PARAMETERS FOR RS-1
FC BACNET GATEWAYS are dedicated for inverters with a communication port Modbus RTU (connected to port RS 485-
2). FC BACNET GATEWAY use port RS 485-1 to connect with main system (BMS, main PLC etc.) by Modbus RTU or
BACnet MS-TP in standard RS-485. The module address / BACnet instance is set using DIP Switch in the range of 1-
255.Switches are configurable in binary mode.
BACnet MS/TP RS-485 default speed value is 76k8.
Setting the RS-485 speed, parity, stop bits and setting the communication protocol is carried out by a DIP Switch. Steps
description below (CONFIGURATION DESCRIPTION section).

CONFIGURATION DESCRIPTION
1. Turn the power module Off, all DIP Switches set to On and switch the power module On
2. After turning the power module On, all DIP Switches set to Off
(LEDs COM and ALR should start flashing alternately)
3. Set on the DIP Switches necessary parameters according to the tables (PROTOCOLE, STOP BITS, PARITY, SPEED) above.

4. FIRST CONFIGURATION (STEP BY STEP)
1. Connect 24V supply to power connector
2. Connect RS-1 to main system (converter, main PLC, BMS e.t.c)
3. Use BACnet tool to connect with GATE by default parameters [BACnet, speed 76k8, instance 1]
4. Configure gate to your system using parameters below

5. ALARM LIST
ALARM ALARM TYPE DESCRIPTION
ComSupFC… Declining Alarm for the lack of communication between the module and the supply /
ComExhFC… exhaust inverter:
Normal state - there is no alarm, communication is correct
Emergency state - there is an alarm, communication is not correct
Reaction to the alarm state: alarm, check the inverter and the way it is
connected to the controller, determine the cause of the error, after removing
the cause, the alarm disappears automatically
SupFC…badSeries Declining Alarm for incorrect model supply / exhaust inverter:
ExhFC…badSeries
Normal state - there is no alarm, the physical model of the inverter is as set in
the application
Alarm condition - there is an alarm, the physical model of the inverter is not
compatible with the set in the application
Response to an alarm condition: alarm, check the inverter and configure the
system properly
