Hi All, I have S7-300 Software redundancy with following
My S7-300 R system is working fine. I am facing problem for HMI connectivity with CP343-1. If CPU-A is master then HMI is communicating with CPU-A via CP343-1. If CPU-A is fail then HMI also switching to CPU-B via CP 343-1. I need solution for following problem. If CPU-A is master and HMI is communicating with CPU-A via CP343-1. Suppose CP343-1 communication cable is break so HMI communication will break but still CPU-A is master so HMI is trying to communicate with CPU-A only. On the event of communication break between HMI and CP 343-1 I want to Switch Master CPU to Standby CPU ( CPU-A to CPU-B ) or vice versa. Please find the attached System Architecture for reference. Please let me know how to achieve this. Regards, Yogendra AttachmentSA.pdf (34 Downloads) |
