PM865 处理器单元 以太网端口

PM865 处理器单元 以太网端口

PM866  控制器的底板有两个用于连接控制网络的 RJ45 以太网端口（CN1、CN2）和两个 RJ45 串行端口（COM3、COM4）。

其中一个串行端口 (COM3) 是带有调制解调器控制信号的 RS-232C 端口，而另一个端口 (COM4) 是隔离的，用于连接配置工具。该控制器支持 CPU 冗余，以实现更高的可用性（CPU、CEX-Bus、通信接口和 S800 I/O）。

使用独特的滑动和锁定机构，简单的 DIN 导轨安装/拆卸程序。所有基板均配有唯一的以太网地址，为每个 CPU 提供硬件标识。该地址可以在 TP830 基板上贴的以太网地址标签上找到。

The baseplate of the PM866 controller has two RJ45 Ethernet ports (CN1 and CN2) and two RJ45 serial ports (COM3 and COM4) for connecting to the control network.

One of the serial ports (COM3) is the RS-232C port with the modem control signal, while the other port (COM4) is isolated and used to connect to the configuration tool. The controller supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interface, and S800 I/O).

Simple DIN rail installation/removal procedure with unique sliding and locking mechanisms. Each substrate is equipped with a unique Ethernet address that provides a hardware identity for each CPU. This address can be found on the Ethernet address label attached to the TP830 substrate.
