14.2.5 Example of Working with Address Locations
You want to determine at which locations output Q1.0 (direct/indirect) is set. The following STL
code in OB1 is used as an example:
Network 1: ...........

Network 3:
//comment line only
SET

Network 4:
A I 1.0
A I 2.0
= M2.0 // assignment
This results in the following assignment tree for Q1.0:
