6.10 Edit a Sequence
Once you open a new sequential chart file, the initial step is displayed. The execution
of a step always starts from here. In order to add new elements to the drawing
you can either use the toolbar or the keyboard.

the SB list and load the SB “OpenMain-
Gate”. Do the following exercises:
1. Select the " Mixed Mode "
2. Move the pointer under the the initial
step and click the left mouse button.

again.
4. Follow this format.

Draw a connection:
Once the sequence is finished the program
is finished also. If you want the program to
restart, then add a loop. You cannot draw
a connection between two steps or between
two transitions. A loop always starts
at a transition and goes to a step.
1. Select the "Select Mode"
2. Mark the transition you start from.
3. Select the "Link Mode"
4. Click on the step that you want to connect
to the transition.
