How to represent bus bars on schematics in Promis.e?
A bus bar is a metal bar or plate that conducts electricity, distributing it to devices. Therefore it serves the same purpose as a wire, and like a wires it is often represented by a line on a schematic. However, if Draw Wire is used to draw a wire to represent the bus, devices will appear as connected to each other instead of the bus bar on various dialogs and wire list reports. In that respect, bus bars would be better represented as devices than wires. This article describes some options for representing bus bars in this manner.
Pros: Simple and flexible. Less manual hiding/displaying device IDs and cross reference text than Option 2.Cons: Cannot share potential via potential group in symbol or family.
The green rectangle in the above screen shot is the Symbol On The Fly box. Two connection points have been inserted into the symbol on the fly.
Pros: Flexibility, can share potential via potential group in a family.Cons: May need to hide cross references.
Wire links can be used to continue the potential to other pages.
Pros: Ease of use after upfront work, can share potential via potential group in symbol or family.Cons: Not flexible, requires more upfront work
Similar to the individual connection symbol method above, symbols that span sections of pages or the entire page and include several connection points and the bus bar graphics can be created. For example, a symbol representing three phases of bus bar and spanning the entire schematic page could be created. Potential can be shared within the symbol definition, or across symbols via a family (specify the same value in the Group Name column in the Potential Groups pane on the New/Modify Family dialog).
Wire links can be used to continue the potential to bus bar symbols on other pages.
