I need clarification and guidance - consider me a total noob
There are a few things I am not understanding and I am sure that is due to my in-experience with this design concept. My background is 2 years of windows desktop hardware support and then jumping into the industrial automation control world at the HMI GUI development level with no prior training for a OEM. 98% of my experience has been hands on learning, on the fly, with Rockwell Automation Factorytalk View Studio in both Site Edition and Machine Edition, that last 2% was a single Siemens job we stumbled our way through.
What I am not understanding and not able to find any detailed information on is how external data is connected and communicated in Storyboard. I am used to working with PLC controllers and ladder logic, structured text is not a new concept for me but the addressing I am used to seeing probably differs greatly from the practice used in applications like Storyboard. I can work my way through ladder logic and find the "tags" I need but part of that is because our tag structure for touch screens is specifically unique compared to the rest of the logic we use.
I assume this is a place where I need a OPC to do the translation between the tag structure in the Allen-Bradley controller and the storyboard IO connector, but again I don't see how I get from Storyboard to the Rockwell Gateway software - or to any external source for that matter. Even if I was using Basic on a BeagleBone Black I don't see where that addressing occurs in Storyboard.
obviously I am missing something that is in most cases very clear, but I think I lack the experience in this side of Automation control to make the information connections I need; can someone point me in the right direction?
