Does Ignition provide an easy way to replace all the tag binding on a single page with new tags? I’m looking for something similar to Intouch’s tag replace feature.

For example, I make a page for a single pump which contains tags specific to that pump (pump1\_run, pump1\_stop,etc.)

Now I wish to create an identical page for another pump. It should be a simple matter of copying the original page and replacing every instance of my pump1 tags with my pump2 tags. (pump1\_run becomes pump2\_run, pump1\_stop becomes pump2\_stop, etc.).

Unfortunately, the only way I can see to accomplish this is to manually go through each component on the page and change the bindings in the property editor. Does anyone know of a solution to this?

BTW, I am aware of the Find/Replace function, but, as far as I know, that serves a very different purpose.

Any help much appreciated.

Hi there,

Ignition handles what you are describing in a different way. In Ignition you would handle this by using indirect bindings.

The idea here is to use the same window for different pumps – the binding changing depending on what pump you want to see. That way you don’t have to create multiple windows for the same functionality.

I suggest you watch this video about Indirect Tag Bindings:  
[inductiveuniversity.com/video/i … ag-binding](https://inductiveuniversity.com/video/indirect-tag-binding)

You can also read about Indirect Tag Bindings in the Ignition manual here: [docs.inductiveautomation.com/di … ag+Binding](https://docs.inductiveautomation.com/display/DOC79/Indirect+Tag+Binding)

Best,

Thanks very much. Still new to ignition so that’s a feature I’d missed completely. One more, small question.

Can I use indirect tags in a binding expression?

So, given a very simple expression “{PLC/CP2/pump1\_runs} && {PLC/CP2/pump1\_auto}”.  
I wish to copy this component and replace the tags for multiple pumps: “{PLC/CP2/pump2\_runs} && {PLC/CP2/pump2\_auto}”, etc.

Is this possible using indirect tag paths?

[quote=“conlonj25”]I wish to copy this component and replace the tags for multiple pumps: “{PLC/CP2/pump2\_runs} && {PLC/CP2/pump2\_auto}”, etc.[/quote]Indirect tag paths are really just strings, so you can create a computed tag path property with an expression that assembles the tag path the way you want (as a string) and then use that property in your indirect reference.

Hi conlonj25,

Yes, you can use indirect tag paths in expressions. You do this by using the tag expression function.

Here is an example:

```auto
tag("PLC/CP2/pump"+{Root Container.pumpNum}") && tag("PLC/CP2/pump"+{Root Container.pumpNum}+"_auto")
```

Best,
