James WhiteKarma: 19Rank: PadawanIs there a way to move local/program tags to controller tags without doing it offline?
PLCGuruHi James,
Unfortunately there is no way to do this online. When you’re creating tags essentially what you are doing is allocating a block of memory whose size is based on the data type you choose. For example, an INT will allocate 16-bits of memory which can represent a number from -32,768 to 32,767. Whereas, a DINT will allocate 32-bits of memory for that tag which can represent a much bigger number -2,147,483,648 to 2,147,483,647. These memory allocations cannot be changed dynamically at runtime.
Hope that helps!
Ken SKarma: 172Rank: JediJust create controller tags with the same name, and change the tag for the instructions to use the controller tag. Then delete the program tags.
If you have a lot of them – I exported and edited the exported file in EXCEL and then re-imported it, that made it quick a 5 minute downtime operation versus a lot

Ken SKarma: 172Rank: JediWhat I mean is the excel file shows program tags one way and controller tags another way – just match the same pattern in the excel file for controller tags and you will have an easy import.
PLCGuruSome great tips here Ken! I’m seeing one of your posts here twice…hmmm. That’s strange.
