描述

140CPU67160  Quantum RIO主站通讯适配器模块

140CPU67160热备系统介绍：

热备系统最基本结构：

Quantum 140CPU67160 CPU模块

Quantum 电源模块

Quantum RIO主站通讯适配器模块

热备系统可选模块：

Quantum 140NOE771xx以太网通讯模块

Quantum 140NOM MB/MB+通讯模块

I/O 信号处理：

Quantum Unity 热备系统支持RIO，也支持以太网IO扫描，但是不支持本地I/O和分布式I/O。

本地I/O和分布式I/O可以在热备系统中配置，可以运行，但不能当做冗余系统的一部分。

主、备控制器的工作状况

主控制器执行应用程序，控制RIO，在每次扫描周期与备控制器做数据同步。备控制器不执行全部的应用程序，只执行应用程序的第一部分代码段。备控制器不控制RIO模块，只检验热备系统的可用性。注：RIO模块只由主控制器来控制

上电处理

上电时，MAC地址最低的控制器为主控制器，另一个控制器自动成为备用控制

热备系统正常状态灯显示

主机：CPU显示“Run Primary”，CRP显示“Ready”、“Com Act”灯绿色常亮。

备机：CPU显示“Run Standby”，CRP显示“Ready”灯绿色常亮、“Com Act”灯绿色均匀慢闪烁。

主机以及备机的HSBY Link的“COM”灯黄色常亮、“STS”灯黄色闪烁。

与Concept热备系统的区别

Quantum热备系统没有采用Concept Quantum热备系统的热备模块140CHS11000，而是采用嵌入式Copro处理器来提供专用的通讯链接，在主控制器和备控制器之间交换数据。这个专用通讯链接不能用于其它通讯。
2.在Concept Quantum热备系统的热备模块140CHS11000上使用的光纤连接不能用于Unity Quantum热备系统。
Quantum热备系统使用系统字%SW60读取、写入热备系统命令寄存器，使用%SW61读取热备系统状态寄存器，使用%SW62、%SW63做为反向传输寄存器，为反向传输过程预留。而Concept Quantum热备系统采用定义非传输区，非传输区定义后前4个字用于热备系统的命令寄存器、状态寄存器、反向传输寄存器。即Unity Quantum热备系统的这四个字不再保存在State RAM的4x寄存器中。
Quantum热备系统不再需要在软件中加载CHS Loadables。
140CPU67160实验用热备系统结构

1.主机与备机的CRP模块通过分离器与一个分支器连接一个远程分站，同时软件中选择“At Least One RIO drop”，连接光纤型号490NOR00003。
2.主机与备机的CRP模块之间直接使用一根铜轴电缆连接，同时软件中选择“No RIO drop”，连接光纤型号490NOR00003。(前提条件：Unity 软件版本高于V3.1，140CPU67160 CPU固件版本号高于2.5，协处理器固件版本号高于2.5)
热备系统程序传输方式

模块前面板上热备子菜单上操作“传输”
2.命令寄存器系统位%SW60.5置1
3.当备用控制器为空，没有任何程序配置时，主机将自动将程序传输到备机

140CPU67160 Hot Spare System Description:

The basic structure of the hot spare system:

Quantum 140CPU67160 CPU module

Quantum power module

Quantum RIO master station communication adapter module

Optional modules of hot spare system:

Quantum 140NOE771xx Ethernet communication module

Quantum 140NOM MB/MB+ Communication module

I/O Signal processing:

The Quantum Unity hot spare system supports RIO and also supports Ethernet IO scanning, but does not support local and distributed I/O.

Local I/O and distributed I/O can be configured in a hot backup system and can run, but cannot be considered as part of a redundant system.

Operating status of the primary and secondary controllers

The primary controller executes applications, controls RIO, and synchronizes data with the secondary controller during each scan cycle. The secondary controller does not execute the entire application, only the first section of the application code. The standby controller does not control the RIO module but only checks the availability of the hot spare system. Note: The RIO module is only controlled by the master controller

Power-on process

During power-on, the controller with the lowest MAC address becomes the primary controller, and the other controller automatically becomes the secondary controller

The hot spare system is normal indicator

Host: The CPU displays Run Primary, and the CRP displays Ready and Com Act indicators are steady green.

Standby: The CPU is displayed as Run Standby, the CRP is displayed as Ready indicator is steady green, and the Com Act indicator is steady green and blinking slowly.

The “COM” indicator and the “STS” indicator of the HSBY Link on the host and standby are steady yellow and blinking yellow.

Difference from Concept hot spare system

Instead of using the 140CHS11000 hot spare module of the Concept Quantum hot spare system, the Quantum hot spare system uses an embedded Copro processor to provide a dedicated communication link to exchange data between the primary controller and the secondary controller. This dedicated communication link cannot be used for other communications.
2. The optical fiber connection used in the 140CHS11000 hot spare module of the Concept Quantum hot spare system cannot be used in the Unity Quantum hot spare system.
The Quantum hot spare system uses the system word %SW60 to read and write the hot spare system command register, uses %SW61 to read the hot spare system status register, and uses %SW62 and %SW63 as reverse transfer registers reserved for the reverse transfer process. The Concept Quantum hot spare system uses the definition of non-transmission area, and the first four words after the definition of non-transmission area are used for the command register, status register, and reverse transmission register of the hot spare system. These four words of the Unity Quantum hot spare system are no longer stored in the 4x register of State RAM.
The Quantum hot spare system no longer requires CHS Loadables to be loaded in software.
140CPU67160 Structure of the hot spare system for experimentation

1. The CRP module of the host and the standby host is connected to a remote branch station through a splitter. In the software, select At Least One RIO drop and connect the optical fiber model 490NOR00003.
2. Use a copper cable to connect the CRP module of the host and the standby host, select No RIO drop in the software, and connect the optical fiber model 490NOR00003. (Prerequisites: Unity software version is higher than V3.1, 140CPU67160 CPU firmware version is higher than 2.5, coprocessor firmware version is higher than 2.5)
Program transfer mode of the hot spare system

On the front panel of the module, select Transfer from the hot spare submenu.
2. Set the command register system bit %SW60.5 to 1
3. If the standby controller is empty and no program is configured, the host automatically transfers the program to the standby controller
