B & R project problem

Experts in sps-forum have been always kind to me in solving some automation problems.
Now I'm trying to diagnose some B&R servo motors and the goal is to build a B&R project for testing B&R motors.
there is a list of what I have for this aim:

- Acopos 1022 servo drive with AC 110 and AC 120 card.
- some B&R 8MSA servo motors
- PP15 power panel (to say exactly 4PP015.E420-36)
- Automation studio AS_3.090.24 installed on my laptop.

Am I miss any requirments?

1. What is a sink or a source project?
2. Which sample projects is suitable for my goal?
3. and What is automation runtime version mismatch of which prevent building avery project annoyingly?

Any Idea would be appreciated.

Best regards
