SST-PFB-CLX 扫描仪模块 冗余Profibus I/O控制系统
为了设计一个具有ControlLogix架构的冗余Profibus I/O控制系统,采用SST-PFB-CLX卡必须安装在远程ControlLogix机架上。在这个设置中,它与ControlLogix cpu通信通过1756-CNB系列的ControlNet桥接卡。
虽然SST的文档解释了如何设置SST- pfb – clx卡和ControlLogix CPU到通过本地机架进行通信,没有SST文档描述如何远程使用卡(作为冗余系统的要求)。
根据文档1756Soft_HBU.pdf,应用解决方案“软件输出系统”(出版号1756-AP001A-US-E),可以构建ControlLogix冗余系统没有1757-SRM模块,使用阶梯逻辑在cpu之间切换控制。

In order to design a redundant Profibus I/O control system with the ControlLogix architecture, the SST-PFB-CLX card must be installed on a remote ControlLogix rack. In this setup, it communicates with the ControlLogix cpu via the ControlNet bridge card of the 1756-CNB series.
While the SST documentation explains how to set up the SST-PFB-CLX card and ControlLogix CPU to communicate via the local rack, no SST documentation describes how to use the card remotely (a requirement as a redundant system).
According to document 1756Soft_HBU.pdf, the application solution "Software Output System" (publication number 1756-AP001A-US-E), can build ControlLogix redundant systems without 1757-SRM modules, using ladder logic to switch controls between cpus.
