One of my customers asked me this question...
I'm have an issue with a change in the execution order in TestStand 4.1.1. [he has upgraded from 3.1 to 4.1.1] It looks like ProcessModelPreStep runs earlier in 4.1.1 than it does in 3.1. This causes our model to error out because some required variables haven't been defined when it runs. I wish there was a big flow chart or state diagram for TestStand. Maybe there is and I don't know where to look?

Starting with TS 4.1, there is a flow diagram that can be displayed for a selected sequence...
Select "View -> Sequence File -> Display File Hierarchy"

The Callback you describe is an Engine callback and is independent of the process model. There is a list of every action and their order described in the TestStand Reference Manual in Chapter 3 in the section titled "Step Execution". You will see Action 11 is the Pre-Step Engine callback.
