3.1 PM CPU modules

PM CPU模板

 

The PM CPU module is the basic component of the AC 900F controller. It comes with a high-performance processor for multitasking and for processing tasks with short cycle times.

 

PM CPU 模块是AC 900F 控制器的基本组件。它具备短周期多任务多处理高性能处理器。

The module is equipped with three or four on-board Ethernet network connections of 100 Mbit/s and two serial interfaces. A third serial interface is provided for diagnostic purposes and for the connection of a radio clock

该模板配备3到4个板载100Mbits/s以太网接口和2个串口。第三个串行接口用于诊断目的和无线电时钟的连接.

Additional modules can be added on the left and right sides of the CPU module using the coupler bus slots and an I/O bus interface

可以使用耦合器总线和IO总线接口在CPU模板左右两侧添加模板

The TD display unit shows the system status and diagnostic data directly at the module. The operating mode can be changed using the switches provided on the front panel of the CPU module

TD 显示单元直接在模块中显示系统状态和诊断数据。使用 CPU 模块前面板上提供的开关可以更改操作模式。
