The gateway would have RS485 port/s and Modbus RTU protocol drivers for communicating with the EM6400 energy meters. Serial Modbus Slave devices are identified by a station number which precedes the general message structure. Generally, up to 32 stations are supported as that is the limit imposed by most RS485 serial drivers. General characteristics BMS (Building Management Systems) are systems providing integrated management of all the technological functions of a building, including access control, security, fire alarms, lights, intelligent lifts and air-conditioning. 连接到电脑上用串口助手看,数据很正常; 2. The Modbus protocol was developed in 1979 by Modicon, Incorporated, for industrial automation systems and Modicon programmable controllers. You should start with configuring the Comm port for "2 wire Modbus" (I'm presuming "2 wire" means 2 wire half duplex RS-485). NET Framework 4. Energy Meter (RS485) ---> RS485 to RS232 converter ---> RS232 to USB converter ---> Windows PC By doing this I successfully got the data in ModScan Software from WinTech. ModbusはModicon社が1979年、同社のプログラマブルロジックコントローラ (PLC) 向けに策定したシリアル通信 プロトコルである。 産業界におけるデ・ファクト 標準の通信プロトコルとなり、現在では産業用電子機器を接続する最も一般的手段となっている。. 輸入Smartlink modbus 的 Device ID. I just cant figure how to tell the plc to read them. The communications interface is RS485. Release Notes: Modbus/UDP and Modbus/RTU (master only) implementations were added along with support for RS485 Echo, a missing standard function (write multiple coils), and facade pattern TCP and UDP masters. (So you might have up to 10 RS232 devices, 100 RS422, 320 RS485 or many Modbus and TCP/IP devices. 232 or RS-485. Introduced in 1979 by Schneider Electric (Modicon), the Modbus® fieldbus is an essential, open communication standard, supported by a large number of products and vendors on the market today. This software utility is written for testing Modbus slave devices. I was not certain about the ground requirements and left this unconnected to start. The DEM uses the Modbus/RTU protocol.
