A-B 81000-199-53-R Pcb電路板
一般操作條件07KR51-HSB中央單元是根據(jù)歐洲EC指令、主要國家和國際IEC 1131-1和IEC 1131-2標(biāo)準(zhǔn)以及有關(guān)自動化設(shè)備的EN61131-2產(chǎn)品標(biāo)準(zhǔn)開發(fā)的。同一07KR51-HSB中央單元可以配置三種不同的操作模式，具體取決于冗余CS31體系結(jié)構(gòu)中所需的功能：熱備用主中央單元、熱備用自遠(yuǎn)程中央單元，如果熱備用主中心單元電源開啟失敗，則可以單獨(dú)啟動。熱備用遠(yuǎn)程中央單元、，僅當(dāng)之前熱備用主中央單元已在電源打開時正確啟動時，才能啟動。熱備用主、熱備用遠(yuǎn)程中央單元以及遠(yuǎn)程單元可以在總線上以任何順序定位。1.4.2配置軟件界面配置：點(diǎn)擊AC31GRAF編程軟件控制菜單中的“啟動PLC配置工具”圖標(biāo)。然后從“中央控制單元操作模式（CS31總線上的CS31 MODBUS）”線路列表中選擇熱備用配置（見下文）。只有在主控設(shè)備發(fā)生故障時，熱備用遠(yuǎn)程中央控制單元才會啟動對CS31的控制。這意味著熱備用主中央單元必須初始化，并與熱備用遠(yuǎn)程中央單元同步。否則，熱備用遠(yuǎn)程中央單元將無法啟動對CS31總線的控制。如果熱備用遠(yuǎn)程中央單元沒有收到來自熱備用主中央單元的請求，則它將在3-30秒后啟動對CS31總線的控制。如果電源接通后熱備用主中央控制單元可能出現(xiàn)故障，并且應(yīng)用程序必須啟動，則建議使用此配置。
內(nèi)部輸出：
在07KR51-HSB內(nèi)部，存在多個用于管理冗余功能的內(nèi)部輸出。這些內(nèi)部輸出為%O62.08：當(dāng)在熱備用中央單元、主中央單元和遠(yuǎn)程中央單元之間實(shí)現(xiàn)同步時，位%O62.008設(shè)置為1。如果同步丟失，則在兩個熱備用中央單位中位%O62.08重置為0。%O62.09:熱備用中央單元中的位%O62.009設(shè)置為1，該中央單元根據(jù)事件控制CS31總線、主控或遠(yuǎn)程。為了了解CS31總線%O62.10上熱備用中央單元的狀態(tài)：當(dāng)熱備用主中央單元的系統(tǒng)常數(shù)設(shè)置為-5%O62.11時，位%O62.10設(shè)置為1：如果其中一個熱備用中央機(jī)組將位%O62.11設(shè)置為1，則熱備用中央機(jī)、主中央單元和遠(yuǎn)程中央單元都將重新啟動（如熱啟動命令）。此命令是完全重置系統(tǒng)所必需的。%O62.12：位%O62.12用于在一次故障后對主中央單元上的熱備用功能作出反應(yīng)。故障后，如果位%O62.12設(shè)置為1，則熱備用功能啟用，并等待當(dāng)前熱備用主中央單元的下一次故障，以再次恢復(fù)對CS31總線的控制。如果位%O62.12設(shè)置為0，則熱備用中央單元不能在CS31總線上主控。%O62.13:位%O62.12用于強(qiáng)制熱備用中央單元控制CS31總線。如果位%O62.13設(shè)置為1，并且位%O62.10為1，則熱備用中央單元將控制CS31總線，位%O6 2.09將下注設(shè)置為1。
General operating conditions
The 07KR51-HSB central units were developed according to the European EC directives, the main national and international IEC 1131-1 and IEC 1131-2 standards and the EN61131-2 product standard concerning automation devices.The same 07KR51-HSB central unit can be configured with the three different operative modes, depending to the function wished in the redundant CS31 architecture: Hot-stand-by master, Hot stand-by self remote central unit, is able to start alone if hot stand-by master central unit fails on power ON. Hot stand-by remote central unit, is able to starts only if previously the hot stand-by master central unit has started properly on power ON The hot stand-by master, and hot stand-by remote central units, as well as the remote units, may be positioned in any order on the bus. 1.4.2 Configuration Software interface configuration: Click on the "Launch PLC configuration tool" icon in the control menu of the AC31GRAF programming software. Then select the hot stand-by configuration from the list of the "Central unit operative mode (CS31 MODBUS on CS31 bus)" line (see below)The hot stand-by remote central unit will start the control of CS31 only if the master fails. That means that the hot stand-by master central unit has to be initialized and synchronized the hot stand-by remote central unit. Otherwise the hot stand-by remote central unit will never start the control of CS31 bus.The hot stand-by remote central unit will start the control of CS31 bus after 3-30 seconds if it receives no request from the hot stand-by master central unit. This configuration is recommended if the hot stand-by master central unit can be defective after a power supply ON and if the application has to start.
Internal outputs:
Inside the 07KR51-HSB, several internal outputs exist for the management of redundant functionality. These internal outputs are %O62.08: When the synchronization is realized between hot stand-by central units, master and remote, the bit %O62.08 is set to 1. And if the synchronization is lost, the bit %O62.08 is reset to 0 in both hot stand-by central units. %O62.09: The bit %O62.09 is set to 1 in the hot stand-by central unit, who controls the CS31 bus, master or remote depending on events. In order to know the status of the hot stand-by central units on the CS31 bus %O62.10: The bit %O62.10 is set to 1 when the hot stand-by master central unit is with the system constant setting to -5 %O62.11: If the bit %O62.11 is set to 1 by one of the hot stand-by central units, the both hot stand-by central units, master and remote are restarted (like Warm start command). This command is necessary to reset completely the system. %O62.12: The bit %O62.12 is used to reactive the hot stand-by function on the master central unit after one failure. After failure, if the bit %O62.12 is set to 1 the hot stand-by function is enabling and it is waiting for a next failure of the present hot stand-by master central unit to recover again the control of CS31 bus. If the bit %O62.12 is set to 0, the hot stand-by central unit can not be master on CS31 bus. %O62.13: The bit %O62.13 is used to force the hot stand-by central unit to take the control of CS31 bus. If bit %O62.13 is set to 1 and if the bit %O62.10 is at 1, the hot standby central unit will take the control of the CS31 bus, and the bit %O62.09 will bet set to 1.
