A compound symbol is a symbol comprising two symbols or more, where there is a functional relationship between the item types the symbols represent. Compound symbols are created within SLD items. Draw and create the compound symbols in the Catalog Manager. You can view the compound symbol and generate the SLD in Smart Electrical. In this way you can use compound symbols to fully illustrate complex items such as circuits with their internals. When creating a compound symbol or combining two compound symbols or more, the items in the compound symbols must have valid relations.
The following guidelines apply when creating compound symbols:
General Guide Lines
A compound symbol is a group of symbols related to a main item with related item types. The following item types are used as placeholders for compound symbols:
-
Circuits / typical circuits
-
Loads
-
Conventional equipment
-
Generators
After creating a compound symbol, you can select an individual item within the compound symbol, and view the item properties and perform connections to auxiliary points.
After a compound symbol has been created, you cannot break the graphics into individual symbols that can be moved. The compound symbol is treated as a single unit and is moved as one group.
Compound Symbol Composition Guidelines
Circuit / typical circuits
-
Circuit data (main item data).
-
All internals (including metering equipment).
-
All I/O associated signals.
-
Cable item tags associated to the circuit.
-
Schematic item tag.
Loads/converting equipment/generators
-
Main item data (circuit information and properties).
-
Associated control station and associated cable item tags.
-
Associated instruments and their cable item tag.
-
Motor space heater for motors.
-
Schematics item tag.
-
I/O signals.
-
Control or instrument cables item, tags (embedded cable symbols retrieve cable data without referring to their category).
Transformers and generators:
-
Neutral grounding resistor data.
-
Neutral grounding cable data (as property only).
-
Neutral grounding metering equipment data.
