A-B 81000-199-53-R Pcb电路板
一般操作条件07KR51-HSB中央单元是根据欧洲EC指令、主要国家和国际IEC 1131-1和IEC 1131-2标准以及有关自动化设备的EN61131-2产品标准开发的。同一07KR51-HSB中央单元可以配置三种不同的操作模式，具体取决于冗余CS31体系结构中所需的功能：热备用主中央单元、热备用自远程中央单元，如果热备用主中心单元电源开启失败，则可以单独启动。热备用远程中央单元、，仅当之前热备用主中央单元已在电源打开时正确启动时，才能启动。热备用主、热备用远程中央单元以及远程单元可以在总线上以任何顺序定位。1.4.2配置软件界面配置：点击AC31GRAF编程软件控制菜单中的“启动PLC配置工具”图标。然后从“中央控制单元操作模式（CS31总线上的CS31 MODBUS）”线路列表中选择热备用配置（见下文）。只有在主控设备发生故障时，热备用远程中央控制单元才会启动对CS31的控制。这意味着热备用主中央单元必须初始化，并与热备用远程中央单元同步。否则，热备用远程中央单元将无法启动对CS31总线的控制。如果热备用远程中央单元没有收到来自热备用主中央单元的请求，则它将在3-30秒后启动对CS31总线的控制。如果电源接通后热备用主中央控制单元可能出现故障，并且应用程序必须启动，则建议使用此配置。
内部输出：
在07KR51-HSB内部，存在多个用于管理冗余功能的内部输出。这些内部输出为%O62.08：当在热备用中央单元、主中央单元和远程中央单元之间实现同步时，位%O62.008设置为1。如果同步丢失，则在两个热备用中央单位中位%O62.08重置为0。%O62.09:热备用中央单元中的位%O62.009设置为1，该中央单元根据事件控制CS31总线、主控或远程。为了了解CS31总线%O62.10上热备用中央单元的状态：当热备用主中央单元的系统常数设置为-5%O62.11时，位%O62.10设置为1：如果其中一个热备用中央机组将位%O62.11设置为1，则热备用中央机、主中央单元和远程中央单元都将重新启动（如热启动命令）。此命令是完全重置系统所必需的。%O62.12：位%O62.12用于在一次故障后对主中央单元上的热备用功能作出反应。故障后，如果位%O62.12设置为1，则热备用功能启用，并等待当前热备用主中央单元的下一次故障，以再次恢复对CS31总线的控制。如果位%O62.12设置为0，则热备用中央单元不能在CS31总线上主控。%O62.13:位%O62.12用于强制热备用中央单元控制CS31总线。如果位%O62.13设置为1，并且位%O62.10为1，则热备用中央单元将控制CS31总线，位%O6 2.09将下注设置为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.
