Symbols are used in the single-line diagram. Each symbol has at least one state that represents the graphics of a symbol at different positions.
Symbol Editor supports three types of symbol standards. New symbols can only be created under the custom standard.
- ANSI
- IEC
- Custom
Symbor Editor can be used to create dynamic symbols that have different states corresponding to the different signal values supported by the symbol. For example, the symbol states of a breaker (open, close, intermediate and faulty) can be illustrated in Symbol Editor with the help of drawing tools such as line, rectangle, ellipse, curve or polyline. The symbol State value should match the signal Enum value. On the LHMI the symbols are displayed according to the signal value and the matching symbol state value. One of the states is always the default state. Symbols used in SLD Editor show the default state graphics.
There are several options for the symbol size: 1x1 (normal size), 1x2 (height is doubled), 2x1(width is doubled) and 2x2 (both the height and width are doubled).
Custom symbols can be exported from the Graphical Display Editor and reused in other projects.
