How to get fast Indirect Tag Binding

Ignition
1

Good morning,

I'm creating some Indirect binding from a UDT in custom properties but I would like to make it easy to do.

For example my Tag Path are:
mypath{position}/Tec/{specific}/UM
mypath{position}/Tec/{specific}/VAL_AMM

and so one a lot of times

The custom property is an object structured like this:

Property1
 -> UM
 -> VAL_AMM

I can manage the parameter {position} without problem and now I'm setting the {specific} parameter manually as String ( in this case 'Property1').

How can I read the name of the Object Property1 and pass it directly to the parameter so I don't have to insert manually it every time?

Thank you

It isn't entirely clear how your UI is structured, but consider not using such unique indirect subexpressions.

Indirect bindings should always look like {1}/SomeSuffix, where {1} points at {view.params.tagpath}

Where you pass a tagpath from a view into a nested view, use an expression like concat({view.params.tagpath}, '/AnotherSuffix') so that the nested view gets a tagpath parameter already prepared for its own internal use.

Do you think using indirect addressing could put stress on the cpu? Ignition might not perform well. I noticed that some site takes forever to open, it takes long time to download resources to the local. When you click something, it takes a moment for the system to update the tag values, you can see the object turn from error to clear. I wish Ignition optimize performance.

No, not particularly.

That is almost always due to have a large number of resources in the project. Indirect binding is a way to re-use one resource in many places in your project, instead of creating many custom resources, reducing the startup time.

There are so many ways a developer can shoot their own foot when creating Ignition applications that I cannot list them. The ability to make Ignition do almost anything imaginable comes with the possibility of poor implementations. Consider sharing your troublesome projects here for advice in detail.

Thanks for your suggestions, I'll try to figure out a good solution improveing your indirect binding structure.
