how to swap the redundant AC900F controller manually from DigiVis?

From my understanding, i can swap the redundant controller via toggle button on the controller itself.

However, I would like to create a button on DigiVis and manually swap the redundant controller controller.

Is that possible? Is there a system tag for toggling the redundant controller?

hi,

What is usecase ? once a while you need to use this function and should not be operator accessed. And that is the reason system function block is not having faceplate for that. one can create internal variable connect to P/S block and configure it on digivis to trigger redundancy toggle. it's possible but I don't recommend it. but you want this way use it with some user access control.

better way toggle redundancy from controller hw button or if controller is located at far place trigger redundancy from CBF commissining mode. In project tree double click on redundant resource node(or rightclick, header from context menu) > click button Prim/sec. redundancy toggles only if resource is in Running,synch status.
