redundant communication between two Masters S7-400 and Yokogawa?
Hello! I have recently run into a problem regarding my recent project. I need to create a redundant communication interface between two masters, a siemens S7-400(as master) and a unknown yokogawa(also as master). We need to transfer parameters between these controllers, in both directions that is. They have stipulated that it needs to be a redundant. So i will need to have a DP/DP coupler to allow two masters to communicate and a secondary one to create the redundancy. My idea was to use OR gates on both sides to make up for the redundency. Is there anything else I should think about? Should I use the diagnostic bit to determine if one the the DP/DP couplers have failed or isnt recieving and information from it(like profibus fail och other fault like line break)? Thanks in advance
