Opening and using the SC Editor

In the SC editor, you configure new SCs of the type Fixed time and Epics/Balance Local or edit existing SCs of this type. To do so, you can make the following settings:

• Defining SC with frequency (Defining SC with frequency)
• Defining signal groups of SC (Defining signal groups in the SC editor)
• Editing default signal sequences and signal states of signal groups (Editing signal groups)
• Defining intergreens (Defining an intergreen matrix)
• Editing intergreens (Editing intergreen matrices)
• Defining and editing stages (Defining and editing stages)
• Assigning stages to signal groups and selecting a default intergreen matrix (Editing stage assignment)
• Creating stage sequences, interstages, and signal group-based (also known as “phase-based”) signal programs (Editing stage sequence). Using the Vissig add-on module, you may also define stage-based signal programs.
• Defining signal programs (Defining signal programs)
• Editing signal programs (Editing signal programs)
• Editing the interstages created (Editing interstages)
• Defining daily signal program lists (Defining and editing daily signal program lists)

If you have added an SC, you must save the network file *.inpx to open the SC editor.

Note: When in Vissim you edit data that is saved to external files, for example *.sig files, Vissim does not provide the  Undo function for any previously selected commands.

The Signal Controllers list opens. The SCs defined are displayed (Defining SC and signal control procedures).
