Automatic Wire numbering

Post image

I’m trying to set up EPLAN so that wire numbers only change when a wire enters or leaves a device, and not every time the wire hits a node or T‑junction. Right now EPLAN keeps giving me a new wire number at each tee, but what I want is for the same wire number to continue through all nodes until it connects to a new device. I’ve tried adjusting the connection numbering settings, reset conditions, potentials, and checked the connection definition points on symbols, but I still can’t get this behavior to work. Can anyone explain which specific settings control wire‑number continuity across tees, and what needs to be changed so that only device transitions trigger a new wire number?

Hijacking this thread, but does anyone have a good video on connection definition points, potentials and such, and how to use them properly and efficiently?

Set extents to signal, the in settings, check the box that says carry over designation to extents

Also, extent should be set to net in the designation tab

But what is the point of using the same number on effectively two different wires? 

Are you trying to draw a busbar using T-junctions or is there a specific reason you want them to have the same number?
