How Tag import works
KRIS Tag import uses information from an existing PCS 7 project. This project is created on the Engineering Station, the program is loaded onto the controllers, and the visualization is transferred to the WinCC database (OS server). The WinCC database stores all data required to display the program, such as measuring ranges, locations, and technical hierarchies.
Tag import connects to the WinCC database, reads this information, and automatically creates matching data points with the same structure in KRIS. This ensures that the data between WinCC and KRIS always remains consistent. TagImport transfers the information either once or as needed, e.g., when a new plant component is added.
The data points are assigned a DB address, which is used for continuous reading and writing via the plant bus. Additional data, such as the location or unit, is transferred once from the WinCC database or directly from the controllers. If anything changes, Tag import must be run again to update the data.
