For example, if I add a device in order to setup tag binding for a new device, enable it and disable the old device, and then switch back to the old device (and tags) by disabling the new device and re-enabling the old device, would I be able to browse the (bad quality) tags of the new, disabled device from my project to continue working on binding the new tags.
If you’ve brought in tags from the OPC browser into the Tag Browser, you’ve created tags in Ignition - no matter what happens to the device, those tags will still be there. If you are talking about browsed/discovered OPC tags, those will not be available if the device is not connected - while some drivers do “cache” browse results, they won’t use that cache if the device is disconnected or disabled.
Perfect, yes I meant bring them in through the Tag Browser within the project. I just wanted to make sure I can work “offline” when I inevitably have to roll it back because I have run out of time to commission the new HMI. Thanks!
