Scada Courses

I want to brush up my Scada Skills since I am the only person in my company who works in Scada. Is there any way I can do Online Scada courses of vendors like Schneider, Siemens Online like I do schneider university courses. I have contacted the local training centers of Schneider, Rockwell and Siemens here but they are too expensive costing me more than month's salary at beginner level courses only. Advanced are even more expensive. Any help would be appreciated.

Have you tried looking at the user manuals for tutorials?

I know that RSview has several tutorials.
