Real-Time SPC™  Support

Create a Minitab Connect® data table for automatic data collection

Learn more about Real-Time SPC
You can import data from a Minitab Connect table into your Real-Time SPC data collection sampling plans.

Each Minitab Connect table includes data fields and data records. Each column in the table is a data field that has name, type, and format attributes. Each row in the table is a data observation.

To link a data table to a data collection form, your data table must have at least three columns.
  1. Data column — must be a numeric column. See the sections below to set up data columns that contain defects and/or defectives.
  2. Time column — must be a date/time column. The acceptable date and time format is yyyy-mm-dd hh:mm:ss.
  3. Subgroup column — must be a numeric column or a text column.
Note

By default, Real-Time SPC uses the first numeric column as the data column, the first date/time column as the time column, and then the next numeric or first text column as the subgroup column unless you specify other columns.

Follow these instructions to create a standard table for manual data entry. You can also create a table from an existing file or template, create a mashup table, create a custom SQL table, or import data through a connection with a third party application. For more information on specific Minitab Connect connectors, go to Connections.
