Description

A measuring location with offset is used for measurement signals that are acquired at a distance x (offset) in the material flow direction after a standard measuring location. Therefore, a standard measuring location must be defined first, before a measuring location with offset can be configured.

The offset is the distance, specified in the base unit of length (m, cm, ft, etc.), that the material has to travel between the standard measuring location and the measuring location with offset based on the line geometry. This value can be determined from engineering drawings or by measurement.

A measuring location with offset does not require tracking signals such as Tracking ID or Entry/Exit length. Measuring locations with offset therefore have the advantage that they allow the number of standard measuring locations and thus of the material tracking signals Tracking ID and Entry/Exit length to be minimized. Provided the line geometry does not change and the speed is identical after a standard measuring location, downstream measurement signals or sensors can be assigned to one or more measuring locations with offset.

Multiple measuring locations with offset can refer to the same standard measuring location. In the data store configuration (tree) they are positioned under the node for the standard measuring location, sorted by the size of the offset.

These measuring locations do not support strip elongation. The Tracking ID and Length signals are created internally in ibaQDR by applying a length delay to the tracking signals from the reference standard measuring location. If the reference standard measuring location is disabled, the associated offset measuring locations are also disabled.

Measuring locations with offset are only possible in continuous strip lines, i.e. not in hot rolling mills, push-pull pickling lines, discontinuous tandem lines or inspection lines.

Typical applications

  • Coating lines

  • Annealing and pickling lines

Offset

Enter the distance to the standard measuring location in the base unit of length.

Maximum permitted value: 5000

Note that a point must be entered as the decimal separator.

The measuring location is skipped if no data is found

Enable this option, if measuring data may be missing temporarily while the plant and the ibaQDR system should run on. This can be the case, e.g. if machinery is temporarily taken out of operation for operational or maintenance purposes.

By enabling this option, the configuration of an "Enable" signal becomes obsolete in many cases
