Add a data log value to a group

A data log group organizes related data log values that will be collected and stored together in the same row of the data log table.

You must have the May edit data logging user privilege to add, edit, and delete data log values.

Add a data log value to a group

1. Open or go to the Data Logger workspace tab.

2. Select the group or one of that group's existing data log value entries.

3. Do one of the following:

   • Right-click the group or value entry and on the context menu click New Data Log Value.

   • On the ribbon, go to the Home tab and on the New menu click New Data Log Value.

   The new value is added to the bottom of the group's list.

4. In the new value's Properties window, complete the following settings:

   • Value Name

     The name of the data log value. The name should be unique within a data log group so the created view does not have duplicate column names. However, it does not have to be unique across data log groups.

   • Value Type

     The type of data measured by this data log value.

     • String

     • Number

     • Logical

     • Datetime

   • Editable

     When selected, allows the data log value to be modified by an operator. This would typically not be selected only if the data log value is being entered through scripting and an MES API and you wanted to prevent an operator from entering or changing the value.

   • Specifications

     The global specification to which this data log value is linked. Global specification groups may be defined using the Create Global Specification Group option on the context menu of a Spec. Ver. node in the Process window or a Specs node in the Jobs window.

   • Current Value

     The last measured value for this data log value or defines the upper or lower limit value.

   • Data_Log_Value spare1-4

     Optional, user-definable fields for this data log value.

   • Meaning

     The purpose of this data log value, in relation to other data log values.

     The system allows for defining reasonable limits for data log values that can be used in custom interfaces for recording data records. For more in-depth data collection, refer to the MES Quality characteristics and specifications capabilities.

     • None: This value is independent of other values; it represents data to be collected.

     • Upper Reasonable Limit: This value will be used as the Upper Reasonable Limit for the value indicated in the Meaning To Value Index field. If the measured value exceeds this limit, a warning is generated by Data Logger.

     • Lower Reasonable Limit: This value will be used as the Lower Reasonable Limit for the value indicated in the Meaning To Value Index field. If the measured value exceeds this limit, a warning is generated by Data Logger.

   • Meaning To Value Index

     The data log value, belonging to the same data log group, to which this value will be applied as a limit.

5. Save the changes.

You can use the Copy and Paste functions to copy one or more data log values to the same data log group or to another group. You can use the Delete function to delete one or more values.
