现场设备系统集成商(FDSI) Modbus主驱动程序可以集成独立于供应商的单端口或双端口Modbus设备使用几种Modbus协议中的-种I/A系列系Modbus Master驱动允许I/A系列系统从附件中获取实时数据Modbus设备,使用先进的控制算法操作数据,并将输出数据写入的设备。Modbus Master驱动下载到适当的单一或冗余FBM, 并允许FBM转换发送到/A系列的数据系统从现场设备，反之亦然。图1展示了一个典型的配置单路FBM230与串口通信Modbus设备。图2展示了一个典型的例子与FBM通信的配置以太网Modbus设备。FBM230配备四个端口，每个端口它可以配置为使用RS-232, RS-422, 或RS 485物理接口标准。的FBM230支持单端口设备Modbus RTU或Modbus ASCII通信协议,并提供串行/A系列系统与设备。参考PSS 21H-2Z30 B4。 The Field Device System Integrator (FDSI) Modbus Master Driver can integrate single port or dual port Modbus devices that are independent of the supplier. The I/A series Modbus Master Driver allows the I/A series system to obtain real-time data from attachments, operate data using state-of-the-art control algorithms, and write output data to the device. Modbus Master driver downloads to appropriate single or redundant FBM and allows FBM conversion to be sent to/A series data systems from field devices, and vice versa. Figure 1 shows a typical configuration of a single channel FBM230 and serial communication Modbus device. Figure 2 shows a typical example of configuring an Ethernet Modbus device for communication with FBM. The FBM230 is equipped with four ports, each of which can be configured to use RS-232, RS-422, or RS 485 physical interface standards. The FBM230 supports single port device Modbus RTU or Modbus ASCII communication protocols and provides serial/A series systems and devices. Refer to PSS 21H-2Z30 B4.
