You cannot create @-prefixed tags yourself. Only the WinCC PCS7 software can do this. You are not permitted to manipulate these system tags. The system tags are required so that the product works properly.
When configuring AS and OS monitoring using Lifebeat Monitoring, devices must have different names to pictures in the Picture Tree Manager or to internal tags with the @ name prefix.
是WINCC中的说明
