Following the Execution Order of Objects in a Program
As a VEE program runs, the objects execute in the following
order:
1 Start objects operate first.
Figure 70 shows a VEE program with two threads, which
are sets of objects connected by solid lines in a VEE
program. The Start objects, located under Flow
⇒ Start, are
used to operate the individual threads in a program. If a
program includes Start object(s), they execute first.

2 Objects with no data input pins operate next. Data ⇒
Constant objects are often in this category.
3 Objects with input pins will only operate when all
connected inputs are satisfied. (Recall that connecting
sequence inputs is optional.)
