Configure a characteristic’s sample data attributes

The Characteristic Data section includes a list of the sample data attributes that can be configured for the currently selected characteristic.

Sample ID

Specifies the ID of the sample record generated for the characteristic which is to be recorded in the MES database.

Can Collect Result Data

Specifies whether the SRO can collect measurements for a characteristic at run time. If the status of this attribute is set to False, the measurement data for the characteristic is not collected at run time.

Note: In the current version of MES, the Can Collect Result Data attribute is set to True and disabled.

Can Collect Automatic Data

Specifies whether the characteristic should always collect automatic data, never collect automatic data, or use the specification configuration for a sample to determine whether it should collect automatic data at run time. If the status of this attribute is set to Never, no automatic measurements are collected for the characteristic. If the status of this attribute is set to Always, the characteristic collects automatic measurements. If the status of this attribute is set to Use Configuration, the automatic data is collected during run time, depending on the characteristic and the QM specification that is used to generate a sample.

When a characteristic collects data automatically, the SampleID attribute is updated to the most recent sample containing the characteristic. It is not possible to write to older sample characteristic records.

Delay Timer

Specifies a value that identifies the time interval between each measurement data for a variable characteristic. If there is a non-null value for the characteristic's delay timer setting in the database, the attribute contains a default value from the MES database. You can change the default value in the Configuration Editor. This attribute is used when the status of the Can Collect Automatic Data is set to Always or Use Configuration, and there are more than one measurement per sample for the variable characteristic. This setting does not apply to attribute characteristics.

Note

Specifies any additional information that you want to record in the MES database for the characteristic within the specified sample.

Cause Group

Specifies a cause group for the characteristic within the specified sample.

Cause

Specifies a cause for the sample characteristic within the specified sample.

Equipment

Specifies a string that indicates the equipment used to measure the sample characteristic data.

Expose Statistics

Specifies a Boolean value that indicates whether the statistic object attributes for the characteristic are exposed at run time. If you enable this setting, many additional object attributes are exposed at run time. The object attributes are updated when results are recorded.

You should enable the Expose Statistics setting only if statistics are required. For more information, see Characteristic attributes available at run time.

Operator

Specifies a value that identifies who measured the sample characteristic. The user name provided does not have to be an MES user.

Value Number For Result Attributes

Specifies a value number that identifies the measurement data for the characteristic sample. This identifies the particular measurement value (result) within a subgroup for which the result MES attributes are to be updated. For ungrouped variables (individuals) and attributes, the value number is always 1.

Note: In the current version of MES, the Value Number For Result Attributes field is disabled.
