Hello All, Hope you are doing well. Can anybody support me to get solution how I can make PRD\_POP2\_Index integer tag dynamic for different instances to read value. Tanks in advance. system.tag.readBlocking([’[Plant\_Model]PDM/SiteName/AreaName/LotName/LotNo/InternalTags/PopUp/PRD\_POP2\_Index’])[0].value ---

Hi, I think you’ll need to be a bit clearer, I have no idea what you mean. What do you have, and what do you want to achieve ? ---

Hi Pascal, i have created a UDT memory tag named- (PRD\_POP2\_Index) now i want to make this tag dynamic for different instances to read the value by using system.tag.readBlocking ---

What do you mean by “dynamic” ? Each instance will be a new tag, with its own name, its own value, etc. Reading a specific instance will return this instance’s qualified value, regardless of other instances. Can you give an example of what you mean ? ---

I agree that this is very unclear, but assuming that in the tag name “Index” is not literal and is a placeholder for a number index, @Atanu_Sanyal should use indirect binding ---

You can’t make a tag dynamic in the sense that it switches between connecting two or more tags in a PLC or other device. What you can do is create tags for each item you might want to monitor and then access those tags by making an [indirect binding in Vision](https://docs.inductiveautomation.com/display/DOC81/Indirect+Tag+Bindings+in+Vision) or an [indirect binding in Perspective](https://docs.inductiveautomation.com/display/DOC81/Tag+Bindings+in+Perspective#TagBindingsinPerspective-IndirectTagBindingMode)… ---

It would be good etiquette to share what the solution is so that others may benefit too.
