    • An transfer body is provided for interfacing between field devices and a field master. One form of the transfer body is an input/output (IO) body. The IO body has a plurality of in-data registers for accepting data from the field devices, a plurality of out-data registers for sending data to field devices, and an identification register for identifying the data in relation to the field devices. The IO body also has an interface portion having an identification port communicating with the identification register, an in-data port communicating with the in-data registers, and an out-data port communicating with the out-data registers. The body can directly attach to and communicate with a plurality of different types of communications adapters through the interface portion for communication with a field master. The body can also directly attach to and communicate with a PLC type of field master through the interface portion. Each communications adapter is configured to directly attach to and communicate through the in-data port, the out-data port, and the identification port, and wherein each communications adapter is also configured to communicate with one or more types of field masters.
    • 提供传送体用于现场设备和现场主站之间的接口。 转印体的一种形式是输入/输出(IO)体。 IO主体具有多个用于接收来自现场设备的数据的数据寄存器,用于向现场设备发送数据的多个输出数据寄存器以及用于识别与现场设备相关的数据的识别寄存器。 IO体还具有接口部分,其具有与识别寄存器通信的识别端口,与数据寄存器通信的数据端口,以及与输出数据寄存器通信的输出数据端口。 身体可以通过接口部分直接附接到多个不同类型的通信适配器并与之通信,以与现场主机通信。 身体还可以通过界面部分直接连接到PLC类型的现场主机并与之通信。 每个通信适配器被配置为直接附接到数据端口,输出数据端口和识别端口并且通过它们进行通信,并且其中每个通信适配器还被配置为与一个或多个类型的现场主机通信。
