Editing stage sequence

Note: You will need the add-on module Vissig.

You can form stage sequences from the stages defined and create the interstages.

1. Open the SC Editor (Opening and using the SC Editor).

2. Double-click the desired SC in the Navigator.

3. In the navigator, click Stage sequence editing.

The existing stages are displayed in the upper pane. The currently selected stage sequence is displayed in the lower pane.

In the upper pane, you define individual interstages and stage sequences.

Tip: You can change the ratio between the upper and lower pane using the horizontal divider.

Defining interstages

1. Click on the From stage.

The From stage is marked.

2. Hold down the Ctrl key and click on the To stage.

The stages are called 1 and 2.

3. Right-click in the window.

4. From the context menu, choose Create an interstage.

The interstage is created and graphically displayed.

Tip: You can define several interstages, for example, with and without minimum duration, between two stages.

Notes:

In Vissig, a signal group in an interstage can be switched once at most: The signal group can change from Free to Blocked or from Blocked to Free.
If you model an interstage in which a signal group is switched twice, in Vissig you must define a pseudo stage and two interstages, one directly before the pseudostage and the other one following the pseudostage.

Defining stage sequence

You can define a stage sequence for calculating the signal program in the upper pane.

1. Hold down the Ctrl key and click on the desired stage sequence.

2. Right-click in the window.

3. In the context menu, select the entry Create sequence.

The new stage sequence is displayed in the lower view.

4. To add an additional stage to the already defined stage sequence, mark an individual stage and choose Add to sequence in the context menu or double-click the stage.

Deleting stage and stage sequences

To delete a selected stage from the stage sequence, choose Remove stage in the context menu.
To delete the entire stage sequence, choose Clear sequence in the context menu.

Exporting stage sequence as graphic file

1. In the menu, choose Edit > Options Export tab.

2. Make the desired settings for formatting the graphic.

3. From the context menu, choose Export entry.

Creating signal program with fixed cycle time

You can create a signal program with a fixed cycle time via the following functions from the stage sequences:

Enter the cycle duration in seconds in the Cycle time field.
Click on the Create stage based signal program button.

A stage-based signal program with a prescribed cycle duration is calculated. The editing view of the signal programs is opened for further processing of your signal program.

Click on the Create signal group based signal program button.

A signal group based signal program with a prescribed cycle duration is calculated. The editing view of the signal programs is opened for further processing of your signal program.

Manually defining interstages

You can manually define the interstages that you want to use to calculate the signal program.

1. Right-click the gray area between the two desired stages.

2. In the context menu, select the entry Interstages > Create or an existing interstage.

If the interstages are not manually selected, the system checks whether a suitable interstage already exists for each stage change of the stage sequence.

If a suitable interstage exists, the first suitable interstage is used for the calculation.
If a suitable interstage does not exist, a new interstage is created. The new interstage is saved for stage-based signal programs.

The interstage is deleted again for signal group-based signal programs after the calculation of the signal program.

Editing interstage

1. Double-click on the interstage.

The editing view of the interstage opens.

2. Make the desired changes.

3. Click on the icon .

The Stage sequence editing window opens.

4. Click the Save button.
