example, if you apply a supply value to the left power
bus on a ladder, there are a bunch of pilot lights and
relay coils in the ladder. AutoCAD Electrical goes
down the left bus and checks each connected rung.
It reads through contact and terminals, but when it
hits a load on a rung, it accumulates the load value
(if present) and stops going any further on that rung.
The utility still checks the other rungs tied to the left-
hand bus and attempts to find more loads.
Tip: Adding Xdata to library symbols before insertion
You can add the Xdata on the library symbol before inserting it. If a drawing
already contains that block, use the Update Block option before running the
report. Open the library symbol and use the Xdata Editor to add Xdata directly
onto the appropriate TERM## attribute. The following xdata can be added at
the library level:
■ Source - VIA_WD_PWR_SRC
■ Load - VIA_WD_PWR_LOAD
■ Unit - VIA_WD_PWR_UNIT
■ Potential - VIA_WD_POTENTIAL
Set power source/load value
This utility marks a component with a power source and load value. A related
routine, when invoked, then scans the wire interconnections and reports if
there is too much load on a given power source.
