ISPSoft User Manual

Chapter 12 Sequential Function Chart
After the users double-click the action or the transition created in the project management area, the
corresponding program editing window will appear. In the window for the transition, there is a
symbol name which is the same as the transition program name. Please refer to section
12.2.1~section 12.2.2 for more information about editing actions and transitions.
The action and the transition are edited in much the same way as a general POU is. However, there
are no local symbol tables in the window for the action and the window for the transition. If users
want to declare a local symbol table, they have to declare it in the window for the sequential function
chart. Besides, the actions and the transitions in a sequential function chart share the same local
symbol table. Please refer to chapter 8~chapter 11 for more information about programming
languages.
*. If the transition create is assigned to a transition in the sequential function chart, the window for the transition will
be opened after users double-click the transition in the sequential function chart.
If the users want to manage the action or the transition created in the project management area,
they can right-click the action or the transition, point to Action/Transition on the context menu, and
click an item. The users have to notice that the action can not be copied into the Transition section,
and the transition can not be copied into the Action section.
