Have you ever had to respond to requirements in regard to recipe management that exceeded the means of PcVue's recipe module?
I am speaking about things like different user access levels for recipes, tracking of recipe version history, input validation for customizable recipes, export of recipes to a file server, GMP compliance and so on...
What would be the best way to offer such kind of thing? Writing my own custom recipe management in VBA? Buying a 3rd party product (if yes, is there anything independent that integrates well with PcVue)?
P.S.: I have just found the Recipe Sample Project (KB400) which seems to answer at least few of my questions. However, it is still relatively far away from what I need to achieve.

Unfortunately the VBA can't manage PcVue Recipes. There is no read nor send function as we have in Scada Basic.
I think our customers can only work with scada basic to manage our Recipes for their need. They also need to create their own mimics to display and configure their recipes.
I never heard about any external tool but it probably exist.

Sure. Maybe I was not clear enough: I was thinking about completly bypassing PcVue's recipes management and create something custom in VBA which would directly read and write the PcVue variables and which would have its own set of user forms.

No you were clear enough and I fully understood your idea.
But if you use PcVue recipes the writes will be optimized regarding communication protocol.
If you redevelop everything it will not be optimized and I think it can be a big issue.
That is why for me it is not a solution.

You are right! Optimized send is an important point to consider.
However, in the particular case of this potential project we are exclusively speaking of OPC communication and thus the writing is already optimized by default, or isn't it?

Hello,
It is also possible to create dynamic recipes with the SvMgr. They works exactly as PcVue ones.
I attached a small project I made for a customer.

Yes, for me this is the real good solution.
VBA doesn't have function equivalent to set/sendlist, so, no point sending a recipe!
