When concurrently developing an Ignition project alongside PLC code, what is the best way to get the updated tags? Example, when I add new code/tags to the PLC, and then want to use these new tags in Ignition. What I currently do is delete the tags folder from the designer tag tree, and then import all PLC tags which brings in the new ones. Is there a better/quicker way? I tried right clicking and selecting “refresh”, but this does not seem to import new tags. PLC is AB compactlogix L32E connected with OPC-UA. ---

You mean in the OPC browser? There’s a refresh button next to the dropdown that re-enumerates the entire list. That one always seems to work. ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/2/2582b26e9289cd617d3cb72e2f10b8dedbba8d89.jpg) ---

I meant the tag browser; As seen above I have added the tag “HMI\_DN” in the PLC. I want to import this for use in Ignition. I guess with one tag I can add it from the OPC browser to MainProgram in tag browser. But what if I made multiple changes and had many new tags. Is the simplest way what I am currently doing - deleting the folder in tag browser and re-importing from OPC browser? ---

You’ll have to drag any new tags you create from the OPC browser to the SQLTag browser. ---

Consider not adding tags to Ignition unless you actually need them in your application. Even with leased drivers, there’s still going to be unnecessay PLC traffic if you’ve created SQLtags for every PLC tag. Also, many PLCs don’t have structured naming capabilities (or they weren’t used), and you may need to organized your SQLtag names differently to take full advantage of templates and parameterized windows. ---

Only subscribe to what you need.
