The numbers indicate the order in which the contacts are executed. As is shown,
the ordering is from innermost branch to outermost branch. The main branch is
followed until a merge point, at which the preceding split point is found and its
branch followed.

Run to Cursor

A third option is to execute all the way up to a specific block in the chart, by
selecting the desired block and clicking the Run to Cursor tool. A

temporary breakpoint is set on the selected block and the chart is executed only
up to it. The temporary breakpoint is cleared when reached and it does not
appear in the breakpoint list.

When using this tool, be aware that the breakpoint set on the selected block may
never be reached if, depending on the flow of the chart, the block is never
executed. In such a case, the temporary breakpoint will remain set until manually
removed using the

Remove Breakpoint

tool.

7.3.8 Forcing New Tag Values

When you double-click on any tag listed in the Browser tab or Watch Window, a
pop-up window is displayed that allows you to force a new value for the tag. The
new value is treated as real data by the Pointe Controller unit.

This is useful for testing hypothetical conditions that may not be reached in the
normal execution of your project. It can also be used to simulate inputs and
outputs when you are running your project with

I/O disabled

.

WARNING

: Please exercise extreme caution when using this function with I/O

enabled. Forcing a value while I/O is enabled can cause connected equipment to
exceed normal operating parameters.
