I am attempting to relace a few tags with other tags. This is probably a simple scripting command but I can’t seem to find it. For example, when I press a button I want tags 1,2,3, and 4 to be replaced with tags 5,6,7, and 8.

Thanks.

are you talking about taking the values from those tags and putting them in the other tags or actually replacing the tag paths on a component or renaming the tags to different names?

I need to replace the tag path tied to a component. When I navigate to a “change” screen I want certain tags to be tied to the components on that screen. And when I navigate to the same “change” screen using a different button, it will bring it’s own tags along with it.

I believe I need something along these lines:  
but to change the “replace” and “system.tag.writeToTag” with the appropriate swap commands

value = ‘AF Chamber Pressure’  
system.tag.writeToTag(“Memory Tags/1”, value)

replace = “_Tags_/Global/AF\_Chmbr\_Prs/SP\_active”  
system.tag.writeToTag(“Memory Tags/2”, replace)

replace = “_Tags_/Global/AF\_Chmbr\_Prs/SP\_req”  
system.tag.writeToTag(“Memory Tags/3”, replace)

Thanks for the help.

This is the type of Parameter I am trying to recreate in Ignition.

! Parameter files are used with graphic displays to specify the tags a  
! display uses at runtime. The parameter file is passed to the graphic  
! using the /P option of the Display command.  
! Syntax:  
! #replacement=tagname  
! Example:  
! #23=A\_COLOR  
! #23 in any expression in a graphic would be replaced by the tag A\_COLOR.

yes you want to use indirects

[inductiveautomation.com/supp … /ignition/](http://www.inductiveautomation.com/support/usermanuals/ignition/)

also you can look at some of the ignition training videos on the website, but I think you will need to get a password from your account rep.

also youtube has a few examples
