Material data capture

The material data capture tab is used to configure data acquisition for the materials in the TPU. This type of data acquisition is used when data is to be collected when materials reside on a specific position in the process. The materials that are destination for the captured data are not referenced directly by ID, but referenced according to the process position. When material data capture is used, new ports will be available on the TPU for collecting the actual data.

This parameter tab is based on the parameter matrix concept. Use the Add button to add a new row and the remove button to remove a selected row. The columns of the matrix are described below.

Data Name

This is the name of the data definition on which to store the data. The data definitions available are governed by the database configuration.

Data type

This is a read only parameter displaying the data type of the selected data definition. In order to change the data type of a specific data definition the portal must be used.

IMPORTANT! Before the data type of a data definition is changed in the database, it is required that the data definition is removed from the tracker process unit. If not, the tracker process unit will will not function properly. 

Dimension

This is a read only parameter displaying the data dimension of the selected data definition.

Value source

This parameter displays the name of the port used for collecting the actual data to collect. The ports are named MDC <DataDefinitionName>  where <DataDefinitionName> is the name of the actual data definition.

Aggregation

This is a read only parameter displaying how to aggregate the data on the TPU. The aggregation type can only be changed through the data definition configuration page in the portal.

  • Min. The minimum value of the corresponding MDC port when the material is inside the TPU is stored.
  • Max. The maximum value of the corresponding MDC port when the material is inside the TPU is stored.
  • Average. The average value of the corresponding MDC port when the material is inside the TPU is stored.
  • First. The value present on the corresponding MDC port when the material enters the TPU is stored.
  • Last. The value present on the corresponding MDC port when the material leaves the TPU is stored.
  • Std.dev. The standard deviation of the corresponding MDC port when the material is inside the TPU is stored.
  • Integral. The integral of the corresponding MDC port when the material is inside the TPU is stored.
  • OnChange. A new value is stored on the material when the material enters the TPU or the value of the MDC port changes.
  • None. No aggregation. Same functionality as First.

Eng. Unit

This is a read only parameter displaying the engineering unit of the actual data definition.

Description

This is a read only parameter displaying the description of the actual data definition.
