國產(chǎn)PLC可編程控制器控制系統解決方案-UHC-5000-CPU非對稱(chēng)冗余系統搭建

Publication At: 2024-03-02
View: 29988


CPU非對稱(chēng)冗余系統搭建如下:(CPU0與CPU1可任意假定)

啟用CPU0冗余(參見(jiàn)撥碼開(kāi)關(guān)配置)

配置CPU0以太網(wǎng)地址,網(wǎng)關(guān),子網(wǎng)掩碼(參見(jiàn)UHCDesigner工程開(kāi)發(fā)通訊口配置部分)

配置COM1,COM2的波特率,起始位,停止位,校驗位(參見(jiàn)UHCDesigner工程開(kāi)發(fā)通訊口配置部分)

下裝工程(參見(jiàn)UHCDesigner工程調試工程下裝部分)

給CPU0重新上電,等待CPU0到RUNNING狀態(tài)(燈板顯示 03)

啟用CPU1冗余(如果已經(jīng)啟用,這一步可以跳過(guò))如果CPU1在與CPU0搭建冗余系統時(shí),并沒(méi)有啟用冗余,上電以后CPU1將會(huì )處于錯誤狀態(tài)(燈板顯示E1)。

連接CPU1與CPU0的專(zhuān)用冗余電纜

給CPU1重新上電,這時(shí)CPU1會(huì )從CPU0中獲取配置信息,CPU1進(jìn)入CONNECTED(燈板顯示 H3)狀態(tài)


CPU非對稱(chēng)冗余系統搭建如下:(CPU0與CPU1可任意假定)

9.   CPU1進(jìn)入UPDATE(燈板顯示 H4)狀態(tài),開(kāi)始同步所有變量

10. CPU1進(jìn)入BACKUP(燈板顯示 HA)狀態(tài),冗余系統搭建完畢

CPU1的配置信息依賴(lài)于CPU0的配置信息的同步,同步后,CPU1原有的配置信息將會(huì )被刪除。

CPU0向CPU1同步的配置信息包括:

A.所有通訊口配置信息

B.用戶(hù)工程

只有CPU0可以被在線(xiàn)修改以上配置信息,當涉及到以上配置信息被修改時(shí),CPU0會(huì )立即生效,而CPU1會(huì )從BACKUP(燈板顯示 HA)狀態(tài)切換到CONNECTED(燈板顯示 H3)狀態(tài),重新同步配置信息,以及變量。同步完成后,使系統再次進(jìn)入冗余狀態(tài),即CPU1狀態(tài)從CONNECTED再切回到BACKUP。
