140CPU67160? Quantum RIO主站通訊適配器模塊
140CPU67160熱備系統(tǒng)介紹:
熱備系統(tǒng)最基本結(jié)構(gòu):
Quantum 140CPU67160 CPU模塊
Quantum 電源模塊
Quantum RIO主站通訊適配器模塊
熱備系統(tǒng)可選模塊:
Quantum 140NOE771xx以太網(wǎng)通訊模塊
Quantum 140NOM MB/MB+通訊模塊
I/O 信號(hào)處理:
Quantum Unity 熱備系統(tǒng)支持RIO,也支持以太網(wǎng)IO掃描,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可以在熱備系統(tǒng)中配置,可以運(yùn)行,但不能當(dāng)做冗余系統(tǒng)的一部分。
主、備控制器的工作狀況
主控制器執(zhí)行應(yīng)用程序,控制RIO,在每次掃描周期與備控制器做數(shù)據(jù)同步。備控制器不執(zhí)行全部的應(yīng)用程序,只執(zhí)行應(yīng)用程序的第一部分代碼段。備控制器不控制RIO模塊,只檢驗(yàn)熱備系統(tǒng)的可用性。注:RIO模塊只由主控制器來控制
上電處理
上電時(shí),MAC地址最低的控制器為主控制器,另一個(gè)控制器自動(dòng)成為備用控制
熱備系統(tǒng)正常狀態(tài)燈顯示
主機(jī):CPU顯示“Run Primary”,CRP顯示“Ready”、“Com Act”燈綠色常亮。
備機(jī):CPU顯示“Run Standby”,CRP顯示“Ready”燈綠色常亮、“Com Act”燈綠色均勻慢閃爍。
主機(jī)以及備機(jī)的HSBY Link的“COM”燈黃色常亮、“STS”燈黃色閃爍。
與Concept熱備系統(tǒng)的區(qū)別
Quantum熱備系統(tǒng)沒有采用Concept Quantum熱備系統(tǒng)的熱備模塊140CHS11000,而是采用嵌入式Copro處理器來提供專用的通訊鏈接,在主控制器和備控制器之間交換數(shù)據(jù)。這個(gè)專用通訊鏈接不能用于其它通訊。
2.在Concept Quantum熱備系統(tǒng)的熱備模塊140CHS11000上使用的光纖連接不能用于Unity Quantum熱備系統(tǒng)。
Quantum熱備系統(tǒng)使用系統(tǒng)字%SW60讀取、寫入熱備系統(tǒng)命令寄存器,使用%SW61讀取熱備系統(tǒng)狀態(tài)寄存器,使用%SW62、%SW63做為反向傳輸寄存器,為反向傳輸過程預(yù)留。而Concept Quantum熱備系統(tǒng)采用定義非傳輸區(qū),非傳輸區(qū)定義后前4個(gè)字用于熱備系統(tǒng)的命令寄存器、狀態(tài)寄存器、反向傳輸寄存器。即Unity Quantum熱備系統(tǒng)的這四個(gè)字不再保存在State RAM的4x寄存器中。
Quantum熱備系統(tǒng)不再需要在軟件中加載CHS Loadables。
140CPU67160實(shí)驗(yàn)用熱備系統(tǒng)結(jié)構(gòu)
1.主機(jī)與備機(jī)的CRP模塊通過分離器與一個(gè)分支器連接一個(gè)遠(yuǎn)程分站,同時(shí)軟件中選擇“At Least One RIO drop”,連接光纖型號(hào)490NOR00003。
2.主機(jī)與備機(jī)的CRP模塊之間直接使用一根銅軸電纜連接,同時(shí)軟件中選擇“No RIO drop”,連接光纖型號(hào)490NOR00003。(前提條件:Unity 軟件版本高于V3.1,140CPU67160 CPU固件版本號(hào)高于2.5,協(xié)處理器固件版本號(hào)高于2.5)
熱備系統(tǒng)程序傳輸方式
模塊前面板上熱備子菜單上操作“傳輸”
2.命令寄存器系統(tǒng)位%SW60.5置1
3.當(dāng)備用控制器為空,沒有任何程序配置時(shí),主機(jī)將自動(dòng)將程序傳輸?shù)絺錂C(jī)

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
