Options - Shop Floor Tab

Select the Shop floor tab of the Options dialog box to access the options described here.

Lock the following options for shop floor operations

Use the options in this group box to lock options/specifications so that they cannot be modified from the shop floor without a password. After determining which options to lock, you can specify and verify a password, and then lock those features by clicking the Lock button. Once a feature or option has been locked, it will be grayed out on its respective dialog. Note that the locking and unlocking of options will apply to all projects currently on the screen.

Chart specifications

Select these options to lock the control limits, specification limits, runs tests specifications (see Specs tabs of the respective result dialog) and/or set definitions (see Sets tab of the respective result dialog).

Causes, actions, and comments

 Select this check box to prevent the shop floor operators from modifying options on the Alarms tab of the Options dialog box. You can also lock the assignment and/or removal of causes, actions and comments.

Inclusion/exclusion of samples

Select this to lock the option of which samples to include/exclude in calculations and graphs. See the Brushing tab on the respective results dialog box for more details.

Suppress warnings & errors, print them (to text window)

When you set this check box, all warning or error messages that are issued during the auto-updating of charts will not be shown in an alert box (dialog), but instead printed to the current output device ( text window). Use this option if you do not want warning and error messages to interrupt the continuous updating of charts.

Buffer incoming commands/data for x milliseconds

This option controls the delay between the time that the data file is updated, and an update message is sent to the graph. Use this option to fine-tune the performance of a chart that is linked to a continuously updating data file ( via Statistica Enterprise).  

For example, suppose the data file is updated one sample at a time, with n per sample equal to 5. Further assume, that the data are passed to the Statistica data file one point at a time, always 5 individual observations ( one sample) one after another. If the individual observations (as they are passed to Statistica) are separated by some delay, the chart may update five times per sample, (once for each individual observation as it is transferred into Statistica). To avoid this inefficiency, and to update the chart only once per sample, you may need to adjust this parameter.  

For most data collection devices and data gathering applications, the default parameter does not have to be changed.
