FOXBORO FBM242 P0916TA通道隔离输出
每个从设备中的设置点也可以从主设备更改。在使用S1 PQM SETUP\COM1 RS485串行端口\MODBUS通信地址设置点运行通信之前，链路中的每个PQM必须使用不同的从属地址进行编程。EnerVista PQM设置软件是GE Multilin开发的通信程序，可用于查看状态、实际值和设定值。有关EnerVista PQM设置软件的更多信息，请参见第6章。前面板上提供的9针RS232C串行端口允许用户使用个人计算机对PQM进行编程。该端口使用与后端RS485端口相同的通信协议。要使用此接口，个人计算机必须运行继电器附带的EnerVista PQM设置软件。9针和25针连接器的计算机RS232端口布线如下图所示。
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.
