Mike Hello Mike, Yes it is possible. You have to connect the three PLCs into one network. Profibus/MPI. Each CPU has an address. And in the WinCC flex. go to controller and define three connections. One for each CPU. Then connect the Panel to the network and it will work. Regards,

Bullmeister Posts: 33 Rating: (0)	Hi Manfred, Thanks for the reply. What HMI panel do you suggest for the example. Its all new to me at the moment so I am adjusting to the world of Siemens technology. Here is some more information which I hope will help .... The connection to the HMI panel would be made through the CPU card over Profibus. I am unsure what type of data is required yet from the PLC's but is there a HMI panel that can except data from both the Profibus network or the Industrial Ethernet. Thanks for the help. I apologise if my terminology is incorrectly at the moment but with practise I hope to get this correct Regards, Mike

I'm not sure I fully understand what you mean but if you are asking if Siemens Panels can be connected to redundant controllers (Either software redundancy or H-System), then the answer is YES for sure. If youaskifpanel itself can be redundant, you can have 2 panels communicating to the same controllers and showing the same data (and same screens if you want). BUT data archives might get different on both panels. Best regards. H-H Edit, download this video, I hope you will find it useful. http://support.automation.siemens.com/WW/view/en/21063246

Can Siemens HMI provide redundancy?? Hello Bullmeister, Actually I am not sure I have understand you correcllty. If your question is a general, I think H-H had ansered you. But you begin your thread by talking about 3 CPUs. So I think you are taling about three different controllers and you want to connect them to one HMI. In these cases I recommend you to create another thread for two reasons: 1. To make it easy for any body to search for the same subject (i.e. connected HMI to redundant CPUs). 2. To avoid mis understanding by us. Any way, Welcome to Siemens. Regards,
