Hithere, I assume you use software redundancy with S7-300? And now you want to connect a WinCC Advanced RT station? With WinCC flexible it was possible to activate and deactivate connections. We've used this possibility to connect a single HMI (panel) to an S7-400H system. The solution is described here: http://support.automation.siemens.com/WW/view/en/23842653 Especially chapter 5of the pdf document added to this FAQ may be interesting for you. You could try something similar for your solution. The idea is to use the "change connection" function when the S7 PLC is no longer available. This function is also available for WinCC V11 advanced. Please note: The S7-400H is not released for TIA Portal. I'm not sure about software redundancy. My preferred solution would have been to use a small S7-400H (CPU 412H) bundle and WinCC flex Advanced RT, but then again when you are on a tight budget... You could give it a try and see if it works.. Please let us know if this was useful for you. Best regards, Gerard |
