- Lighting system on metro stations is normally controlled using a standalone controller. The controller supported 3rd party integration using Telnet and it was required to control the lighting on the station using 3rd party logic controllers and SCADA application.
- Metro Station had lighting system connected to Lighting Controller.
- BMS was also located on the same site.
- Lighting Controller supports Telnet Protocol for 3rd party integration
- BMS understands Modbus RTU Protocol.
- For monitoring and controlling the lighting system on a metro station, authority wanted to control the switching on and off the lights. BMS also helps in getting the status of the lights.
- Since the lighting controller works on Telnet and BMS understand Modbus RTU, a direct exchange of data between them is not possible.
- On analyzing the situation, ProtoConvert has provided an effective solution.
- ProtoConvert Gateway suggested a Gateway which have 1xRS485 Port, 1xRS232 Port and 1xEthernet Port which understands Telnet and Modbus RTU Protocols.
- We connected Lighting Controller with our Gateway on RS485 Port and BMS on RS232 Port.
- We configured our Gateway such that it will fetch the data from controller and serve it to BMS on RS232 in Modbus RTU Protocol.
- Using our own Telnet Simulator we got the data to our Gateway and with the ModScan tool we could successfully display the same date on BMS.
