On retrieving data from Smart Electrical, Smart Instrumentation creates corresponding electrical tags. You can view these tags from the Domain Explorer or in the Engineering Data Editor.
-
Some tag number properties apply to Smart Electrical data only, and are read- only. You can edit other properties such as Service, I/O type, and Notes.
-
When you retrieve a Smart Electrical PDB (power distribution board) pre-assigned circuit signal, Smart Instrumentation automatically creates a cabinet with the name of the power distribution board associated with the signal. If you delete such a cabinet, its pre-assignment relationship with the signal is lost and you will no longer be able to find the tag for that signal when you select Pre-assigned signals only in the Signal Filter dialog. However, the next time you publish the signal from Smart Electrical and retrieve it into Smart Instrumentation, the cabinet is created afresh.
-
When you download electrical tags from Smart Electrical, after making the I/O assignments, Smart Instrumentation automatically assigns a control system tag to each electrical tag.
-
There are three categories of electrical signals, for each of which the user interface differs slightly, as follows:
-
Signals related directly to PDB circuits that are associated with main equipment; for example, a signal created in a feeder circuit that feeds a motor.
-
Signals directly related to main equipment; for example, a signal created under a motor or a transformer.
-
Signals associated directly with control stations that are associated with main equipment such as motors.
-
-
In the Domain Explorer, electrical tag numbers can be viewed by expanding the Electrical Tags folder.
-
In the Browser module, you can view electrical tag numbers from one of the following browsers:
-
Electrical Tag Browser — Displays data for all tag numbers derived from Smart Electrical signals for all items but does not retrieve data values of associated attributes for signals created under circuits. The software displays data for the main item and associated circuit data.
-
Circuit Related Electrical Tag Browser — Displays data for tag numbers derived from Smart Electrical signals for circuits. If a circuit relates to more than one electrical item, a separate data row appears for each item.
-
Electrical Power Element Browser — Displays electrical properties owned by Smart Instrumentation and Smart Electrical for instruments and cabinets.
