One of the features in DeltaV version 13 is an easier way to manage recipe formulas. When there are dozens of formulas with hundreds of parameters for a given recipe, viewing and editing the values wasn't all that easy prior to V13. We now have the ability to copy, edit and paste formula values with Excel.
First, let’s take a look at a recipe I have in my demo system appropriately named DEMO_WITH_TRAINS along with its 4 configured formulas:
I can right-click on the recipe and select Edit Formulas:
The interface in DeltaV Explorer looks like this:
From here, I can change any of the values just by typing into the fields (remember the values contained within the <> are default formula values). But instead of 10 parameters and only 4 formulas, I could have a lot more, making this a less than ideal interface.
So now with V13, I can select everything and copy it, including parameter names and descriptions to the clipboard:
Open up Excel and paste the data in (I added the green highlight):
You can make any required changes to any of the formula values. What you can’t do is add a recipe parameter (that’s pretty straight forward, right?) or add a new formula (maybe not so obvious – I’ll come back to that in a minute). You could create a master formula Excel file and use a different worksheet for each recipe.
When you’re ready to bring the changes back into DeltaV, highlight the data cells (some or all of the green highlighted data), hit CTRL-C, then go back to the formula dialog in DeltaV Explorer, select the EXACT same size range of cells, right click and select Paste (or CTRL-V). If you don’t make the destination range the exact same size as the source range, you’ll get this type of error message:
If you need to add a new formula, right click on the recipe object and select New Formula:
Fill in the new formula dialog box as necessary:
Now editing the formula values will include your new formula:
There is one final step you have to do in order for the new formula to show up in DeltaV Operate – back in the DeltaV Explorer view, right click on the new formula and select Properties:
You need to check the “Operator can load” box which will then cause a Yes to appear in the “Release to production” column in the Explorer view.
