I have been watching this project now for a couple of years and congratulate the developers on a fine comprehensive package. I was involved in the SCADA industry for some 30 years and now retired. I though I would get to know the package better by trying to implement my own project of controlling traffic on small railway, that way you find out quickly what you don't know.

So I have come to a problem I will explain using the demo project AGLKS. On the Mainstation page, if you left click on the ball valve KSH1 and bring it into focus, this then opens on the control page "Element cadr". The parameter value shifr of KSH1, some how gets to parameter prmShifr of Element cadr. I cant seem to find how this happens. I must be missing or not understanding some point in the comprehensive documentation.

I would be very grateful if some one would point me in the right direction.

Bob

In whole that is performed by the dynamic links by the reserved group "<page>".
And how it work you can see in the VCA session context.

Learn, learn and learn better than work, work and work.

Leads followed with success. I was making the problem more complicated than needed. In my version of pg_ElCadr configuration template I typed <Page> instead of <page>.
All now well and I can proceed with my endeavors.

Many thanks Roman for your time and guidance from downunder.
