Honeywell 51401583-200网络接口卡
一般设置规则为了确保此功能，体系结构必须有一个07KR51-HSB中央单元配置为主热备用，一个从07K51-HSB-中央单元配置为从远程热备用。每个07KR51-HSB中央单元包含特定数量的二进制输入/输出。通过增加不同的分机直接连接到07KR51-HSB中央单元，可以增加二进制或模拟输入/输出的数量。这些扩展与标准40和50系列中央单元相同。（见技术文件内的参考资料–1SBC260400R1001）可以通过CS31双绞线使用分散输入/输出装置：-ICMK14F1或ICMK114N1远程装置+其自身的基本扩展-07KR51或07KT51基本中央装置，配置为从模式。-DC551远程单元+其自身的基本扩展在AC31GRAF编程软件下无法使用以下功能块（MT_CS31、MR_CS31，ST_CS31和SR_CS31），以简化07KR51-HSB主中央单元和基本从中央单元之间的通信。为了使用S500远程装置DC551+自己的基本扩展，需要使用特定的功能块来配置输入/输出参数。这些功能块仅适用于AC31GRAF编程软件。两个中央单元（主HSB和从HSB）的周期时间必须设置得完全相同，以实现完美同步。建议不要加载超过50%的内存

General set-up rules
In order to assure this functionality, the architecture must have one 07KR51-HSB central unit configured in master hot stand-by, and one slave 07K51-HSB central unit configured in slave remote hot stand-by. Each 07KR51-HSB central units incorporate a specific number of binary inputs / outputs. And it is possible, to increase this number of binary or analog inputs / outputs, by addition of different extensions directly connect to the 07KR51-HSB central units. These extensions are the same that used with standard 40 and 50 series central units. (See references inside technical documentation – 1SBC260400R1001) It is possible to use decentralized inputs / outputs units via the CS31 twisted pair: - ICMK14F1 or ICMK14N1 remote units + its own basic extensions - 07KR51 or 07KT51 basic central units configured in slave mode. - DC551 remote units + its own basic extensions It is not possible to use the following function blocks (MT_CS31, MR_CS31, ST_CS31 and SR_CS31) under AC31GRAF programming software, to simplify the communication between the 07KR51-HSB master central unit and basic slave central units. In order to use the S500 remote units DC551 + its own basic extensions, it is necessary to used specific function blocks in order to configure the inputs /outputs parameters. These function blocks are only available with AC31GRAF programming software. The cycle time of both the central units, master and slave HSB, have to be set exactly similar for a perfect synchronisation. It is not recommended to load more than 50% of the memory
