TestWare-SX Program Control

The program control process is a special process and should be sequenced in parallel with command processes.

How it works

The program control process works like a custom interlock. Use this process to stop a test before it is complete. It is commonly used in conjunction with other event detector processes.

The other TestStar processes can prematurely end a step but not the test program. This process offers several levels of program control. For example, assume test is operating in force control, two limit detector processes monitor the displacement sensor and trigger a program control process. One process displays a message when the sensor output exceeds 2 mm. The second process causes a hydraulic interlock when the sensor output exceeds 3 mm.

More Information

The Program Control Design window names the process and sequences it in a test template.

The Program Control Parameters window defines the characteristics of the process.


Program Control Design Window

This window specifies when the process starts and stops. The information in this window is saved with the test template.

Label

Names the process. Type the name you want to call the process in the entry field.

Start Trigger

Specifies the beginning of the process. The start trigger for this process is usually the end trigger of an event process or data acquisition process.

End Trigger

Specifies the end of the process. Press the list icon and select a trigger.

More Information

You can find detailed information about this process in Chapter 6 of the 790.10 TestWare-SX Application Manual.

After you complete this window, you can double-click the name of this process in the Edit Template window to display the Program Control Parameters window. This allows you to assign parameters to the default procedure.


Program Control Parameters Window

You must create a program control process in a template with the Program Control Design window before you can access this window. The information in this window is saved with the test procedure.

Action

Selects the action that the process performs. None disables the process.

Message Only displays a message window.

Program Hold suspends the test. It functions the same as pressing the Hold pushbutton.

Program Stop stops the test. It functions the same as pressing the Stop pushbutton.

HPS Interlock stops the test, removes hydraulic pressure at the pump and generates a hydraulic interlock.

Error stops the test and generates an error. TestWare-SX must be reset using the Control menu.

Message

Enters the message that is displayed (or recorded) when the process occurs.

Send To

Selects where the message occurs. Any combination of the three locations can be selected.

Screen displays the message in a dialog box on the computer screen.

LUC Display displays the message in a pane on the load unit control panel.

Data File writes the message to the data file. This is ignored if a data file is not used..
