Hello Parmar; What makes you think that synchronization modules support redundancy inherently? From the S7-400H Fault-tolerant System manual, ch. 15, Synchronization modules:http://support.automation.siemens.com/WW/view/en/1186523 If you remove a synchronization module in redundant system mode, there is a loss of synchronization. The reserve CPU changes to ERROR-SEARCH mode for some minutes. If the new synchronization module is inserted and the redundant link is reestablished during this time, the reserve CPU switches to redundant system mode, otherwise it switches to STOP. Hope this helps, Daniel Chartier |
