good afternoon, dear friend, I need to redundancy CPU, but not of perfiferia (my I / O are not redundant) systems S7300 use the im-153-3 module, but this does not help me as i / or redundant the sitema S7400H. Is there any module that allows me to do this? thanks for your reply soon |

Hello josé; The picture you showed in your first post is taken from the S7-400H manual, and shows a typical arrangement for CPU redundancy: Extract from Section 4,2, describing requirements for the example used in the S7-400H manual: The modules required for the hardware setup available: ● An S7-400H automation system consisting of: – 1 UR2–H rack – 2 PS 407 10 A power supply units – 2 H–CPUs – 4 synchronization modules – 2 fiber-optic cables ● An ET 200M distributed I/O device with active backplane bus with – 2 IM 153–2 – 1 digital input module, SM321 DI 16 x DC24V – 1 digital output module, SM322 DO 16 x DC24V ● All necessary accessories such as PROFIBUS cables, etc. This is not the only way to setup the IOs for CPU redundancy, but it is the most comman and gives the best (and fastest)results when the active CPU switches to the standby. Study the S7-400Hmanual for more details on how to setup the IOs differently, for example in chapter 13, "Using I/Os in S7-400H"which not only describes the different configurations but also discusses the efficiency of each. Hope this helps, Daniel Chartier |
