Hi all,
As you might have picked up I’m trying to use a string in a group level custom property (Root Container.Group 9.Base = “[Client]NDFTags/FactoryPower/SUS1”) so that components within the group can use that base for calculating values. The easy way to get around this is to have half a dozen group level properties directly bound to the appropriate tag values, but that doesn’t scale very well past this sandbox project I’m using. What already works looks like this:
{Root Container.Group 9.CurrLoad}/{Root Container.Group 9.ParentLoad}What I would like to do is have value expressions that look more like this:
{{Root Container.Group 9.Base}/CurrLoad}/{{Root Container.Group 9.Parent}/CurrLoad}But of course Ignition doesn’t like nested paths.
There’s an obvious benefit to being able to include something like a variable in the tag path: I can put this in the Custom Palette and when I need to place copies all I have to change is one or two tag paths instead of 6 (and likely much more in similar components as the system develops) tag links. Is there a way to work around this? Is my problem syntax or is there just no way to do what I’m trying to do?
Thanks.
