Station settings
The station settings are in a pane that can be expanded to change settings and collapsed to view the control charts more easily.
The station is online.
The station is offline.
- Product/Process
- Select which product and process to monitor. Many products and processes can use the same station, and each combination has its own sampling plans and control charts.
- Status
- Select whether the online station is Running, Idle, or Shutdown.
- Sampling Plans
- Lists the sampling plans for the current product, process, and station.
For on-demand and scheduled collections, select Start to open the data collection form. Open the Settings
to skip the next collection.
Data collection controls
Pause or resume data collection
Select Pause Data to pause the station data at any time. Select Resume Data to continue collecting data at this station.
Open the Settings
to
change the control chart display options.
Chart and date selector
Use the chart and date selector to control how data is displayed for each measure. Toggle between the control charts, data tables, and Pareto charts for each measure of the station.
Specify the data range for this dashboard. Generally, this view is for the last 4 hours of data, but can display up to 90 days of available data.
Recent subgroups
When you select All subgroups, the control chart displays the maximum number of subgroups per the global setting maximum.
For more information on the maximum number of subgroups preferences, go to Display options.
Charts and data views
- Control charts
- Displays control charts for each measure. The control charts also
indicate the percentage of plotted points that are out-of-specification,
out-of-action, or out-of-control. For more information on these
calculations, go to Current Performance Summary.Engineers can hide control charts by measure on the station dashboard. This setting is on the Components page in the process step on the product. For each control chart, you can display all the charts, only the first chart, or no charts. For more information, go to Control chart settings for each measure, then select Display on station dashboard.
Note
Real-Time SPC may limit the amount of data that is shown in the control charts to ensure optimum readability. To display more data, if available, select the link in the footer of the chart.
- Data
- View and edit chart data on a spreadsheet. Each row includes appropriate
descriptors, tags, and specification limits. For more information on
interpreting the data tables, go to View data for each measure.To edit, select a row and then select Edit Subgroup or Edit Observation. You can also edit the data from the control chart view. For more information, go to Edit observations and descriptors.
Note
You cannot edit calculated measures directly. You can only edit them by editing one of the measures within the equation.
- Pareto charts
- Pareto charts are available for both defects and defectives. Defects
represent individual defect occurrences, while defectives represent
units with one or more defects.
- Defect types
- Pareto charts identify the most frequent defect types. Use Pareto charts to focus improvement efforts on areas where the largest gains can be made. Real-Time SPC creates a separate Pareto chart for each defect severity.
- Defective types
- Real-Time SPC creates a separate Pareto chart for individual
defective types and grouped defective types.
Use Pareto charts to investigate the types of defectives and the assignable causes and corrective actions.
Data export
You can export the data from the selected time range to a Minitab worksheet (MWX) or to a CSV file.
