Dear Enigmamachine, I still cannot understand why you want to connect an ET200M on to a Y-Link? See attachment. I am also curious if the tech support told you about this possibility, why they did not give you futher details like FAQ number / link to the download etc.?? Strange...

Hi, Now things are beginning to make sense. Basically you are looking for controller redundancy but not I/O (or rack)redundancy. What you need is single-channel one-sided I/O (for example ET200B). Check chapter 10 in the following manual: S7-400H |
