Tracking IDs are special input signals that are required for accurate material or product tracking in the line. ibaQDR uses these signals for internal management of the measured data, identification of the start of the product, the end of the product, and a change of product, and for subsequent precise assignment of the measurement values to the length.

The following HMI screenshot contains three tracking IDs (ID = 4 red, ID = 5 green and ID = 6 blue) in the line.

In ibaPDA or ibaQDR the tracking IDs are displayed as follows in the graph:

*)The snapshot in the HMI screen above is currently suitable. Welder ID = 6, Annealing, Galvanizing and Skin Pass ID = 5, Shear ID = 4

Tracking IDs must be unique in the line, i.e. a tracking ID may only represent a single complete section (tracked part). When a tracked part has completely left the line, the tracking ID can be assigned again.

In large lines, the tracking IDs are usually generated by a special control unit for material or weld seam tracking and transferred to ibaQDR. In smaller lines, this function can also be performed by a PLC.

In certain cases, it is also possible to use the virtual functions in ibaPDA to calculate corresponding signals, if the line control unit not fully provide them.
