1794-ADN
在石油、化工、冶金等行业的某些系统中,要求控制装置有极高的可靠性。如果控制系统发生故障,将会造成停产、原料大量浪费或设备损坏,给企业造成极大的经济损失。但是仅靠提高控制系统硬件的可靠性来满足上述要求是远远不够的,因为PLC本身可靠性的提高是有一定的限度。使用冗余系统或热备用系统就能够比较有效地解决上述问题。
在冗余控制系统中,整个PLC控制系统(或系统中最重要的部分,如CPU模块)由两套完全相同的系统组成如图2所示。两块CPU模块使用相同的用户程序并行工作,其中一块是主CPU,另一块是备用CPU;主CPU工作,而备用CPU的输出是被禁止的,当主CPU发生故障时,备用CPU自动投入运行。这一切换过程是由冗余处理单元RPU控制的,切换时间在1~3个扫描周期,I/O系统的切换也是由RPU完成的。
