FOXBORO FBM242 P0916TA通道隔離輸出
每個從設備中的設置點也可以從主設備更改。在使用S1 PQM SETUP\COM1 RS485串行端口\MODBUS通信地址設置點運行通信之前，鏈路中的每個PQM必須使用不同的從屬地址進行編程。EnerVista PQM設置軟件是GE Multilin開發的通信程序，可用于查看狀態、實際值和設定值。有關EnerVista PQM設置軟件的更多信息，請參見第6章。前面板上提供的9針RS232C串行端口允許用戶使用個人計算機對PQM進行編程。該端口使用與后端RS485端口相同的通信協議。要使用此接口，個人計算機必須運行繼電器附帶的EnerVista PQM設置軟件。9針和25針連接器的計算機RS232端口布線如下圖所示。
Setpoints in each slave can also be changed from the master. Each PQM in the link must be programmed with a different slave address prior to running communications using the S1 PQM SETUP \ COM1 RS485 SERIAL PORT \ MODBUS COMMUNICATION ADDRESS setpoint. The EnerVista PQM Setup software, a communications program developed by GE Multilin, may be used to view status, actual values, and setpoints. See Chapter 6 for more information on the EnerVista PQM Setup software.A 9-pin RS232C serial port provided on the front panel allows the user to program the PQM with a personal computer. This port uses the same communication protocol as the rear terminal RS485 ports. To use this interface, the personal computer must be running the EnerVista PQM Setup software provided with the relay. Cabling to the RS232 port of the computer is shown below for both 9-pin and 25-pin connectors.
