The gentleman working on our PLC tags has assured me that he updated an OPC tag but when I look in the OPC tag browser, it is not updated. He is telling me that he 100% sure that he has updated the tag. Does anyone know of a reason this would be happening, or can I be confident that the tag has not correctly been edited? I went to the OPC tag browser and hit this refresh button:
But the tags remain the same. I am wondering if maybe there is a bug or odd behavior that people have encountered while trying to access updated tags. My device is a Bradley Allen ControlLogix driver.
