PM864 ABB 控制器单元

Description

CPU板包含微处理器和RAM存储器、实时时钟、LED指示灯、INIT按钮和CompactFlash接口。
PM866/PM866A控制器的基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。控制器支持CPU冗余以获得更高的可用性（CPU、CEX总线、通信接口和S800 I/O）。
简单的DIN导轨连接/拆卸程序，使用独特的滑动和锁定机构。所有基板都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基板上的以太网地址标签上找到。

PM864

The CPU board contains the microprocessor and RAM memory, a real-time clock, LED indicators, INIT push button, and a CompactFlash interface.

The base plate of the PM866 / PM866A controller has two RJ45 Ethernet ports (CN1, CN2) for connection to the Control Network, and two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is an RS-232C port with modem control signals, whereas the other port (COM4) is isolated and used for the connection of a configuration tool. The controller supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interfaces and S800 I/O).

Simple DIN rail attachment / detachment procedures, using the unique slide & lock mechanism. All base plates are provided with a unique Ethernet address which provides every CPU with a hardware identity. The address can be found on the Ethernet address label attached to the TP830 base plate.
