Software Verification and Validation

MTS software is developed using established quality practices in accordance with the requirements detailed in the ISO 9001 standards. Because MTS-authored software is delivered in binary format, it is not user accessible. This software will not change over time. Many releases are written to be backwards compatible, creating another form of verification. The status and validity of MTS’s operating software is also checked during system verification and routine calibration of MTS hardware. These controlled calibration processes compare the final test results after statistical analysis against the predicted response of the calibration standards. With these established methods, MTS assures its customers that MTS products meet MTS’s exacting quality standards when initially installed and will continue to perform as intended over time.

3.0 Designing a Test

3.1.0 Introduction

About this chapter

This chapter contains information about the MPE and Station Manager software, basic test design principles, how tests are executed, and how information about test results is made available. If you already feel comfortable with these test design principles and are ready to begin creating a basic ramp and cycle test, see Creating Ramp and Cycle Test on page 38.

MTS Multipurpose Elite application overview

The MTS Multipurpose Elite (MPE) application is a sophisticated, general purpose test design application that allows you to quickly and easily define complex test designs. The role of either Administrator or Engineer is required to access full functionality of MPE. Operators are allowed to access MPE but only with the same rights they have in MPX.

Note:

MTS offers a companion application to MPE named Multipurpose Express (MPX). You cannot create or modify tests with MPX; it is only to run existing tests. In cases where this manual refers to functionality shared by both applications (such as running tests), the term “Multipurpose application” is used.

The Multipurpose Elite Test Design Guide contains the information you need to begin designing tests and test reports with the MPE application. It includes the fundamental concepts of using the MPE application with the MTS controller software to create and run tests.

This guide does not explain every MPE application feature. Its goal is to introduce the most important features of the application in the context of designing tests and test reports.

This chapter contains conceptual information pertinent to test designs. New users should read this chapter before using the software to gain an overall understanding of the design process. Experienced users can read this chapter to review the high-level activities associated with each design task. Detailed instructions to perform the tasks in this chapter are included in other parts of this guide.

3.2.0 Test Design WorkFlow

This table shows the tasks a test designer may perform to prepare a test for an operator. The order in which the tasks are shown is typical.

3.2.1.0UsingtheMultipurposeApplicationwithControllerSoftware

3.2.1.1.0 Launching MPE or MPX

Note:

If you have a desktop shortcut that opens the Station Manager application and then opens the MPE or MPX application, you do not have to perform this procedure to start the Station Manager application and load the station configuration. For more information about creating this desktop shortcut, see

Creating a Desktop Shortcut That Includes a Controller on page 18.

1.Start the Station Manager application by double-clicking the Station Manager icon located in the MTS 793 Software folder on the desktop; or from the Start menu, go to All Programs > MTS 793 Software > Station Manager. The Open Station window appears.

2.In the Open Station window, select the station configuration file (.cfg) required to run the test (MTS FlexTest 40 with 2 Channel configuration). The .cfg file defines all the station resources that are available for a test.

3.Click Open.

4.The Station Manager window appears, which can be minimized.

Multipurpose Elite Test Design Guide 17

3.0 Designing a Test

Important:

You must leave the Station Manager application open, but you can minimize it so it does not appear on your screen.

MTS TestSuite MPX is the intended operator interface. Do not make configuration changes in the Station Manager application without training from MTS.

5.Open MPE or MPX by double-clicking its icon on your desktop; or from the Start menu, go to All Programs > MTS TestSuite. The MP main window opens. You can now open a test.

Note:

If you have multiple stations, you can create individual shortcuts that are specific to each station.

3.2.1.2.0 Creating a Desktop Shortcut That Includes a Controller

Access:

Tools menu > Create Desktop Shortcut

Note:

This procedure only applies to MTS FlexTest controllers.

There are two types of desktop icons. One opens just the MTS TestSuite application, and the other will open the controller and then open the MTS TestSuite application. The desktop shortcut that includes opening the controller includes the configuration file name in its name, for example, “Multipurpose Express (Station_Configuration.cfg).” If you have multiple stations, you can create a shortcut for each configuration file.

To create the desktop shortcut that includes opening the controller:

1.Open your MTS TestSuite application: From the Start menu, select All Programs > MTS TestSuite > application name.

2.From the Tools menu, click Create Desktop Shortcut. The Create Desktop Shortcut window opens.

3.Browse to the Station Configuration file you will be using, or type the file name in the Station Configuration box. Ensure that this configuration file contains the parameter and tuning sets that you want the operator to use for the tests.

4.If the Controller Name box is not already populated, type the name of the controller you will be using.

5.Click OK. The configuration message that states that the shortcut was created on the desktop appears. Click OK.

6.To avoid confusion, delete other MTS TestSuite application desktop shortcuts.

3.2.1.3.0 Multipurpose Application Startup Overview

After you open your station configuration with the Station Manager application, you open the Multipurpose application, which automatically connects to your station configuration.

Multipurpose projects

When you select a new test, the test is automatically associated with an MTS TestSuite Project. A project is a directory that organizes your test procedures, specimen information, and test run data.

18 Multipurpose Elite Test Design Guide

3.0 Designing a Test

Note:

MTS TestSuite projects are independent of the underlying controller, and are not related to MTS controller projects or the MTS Project Manager application.

3.2.2.0 Creating Tests Overview

From the File menu, you can create new tests as follows:

Creating New Tests

File Menu Option

New Test

Creates a new test that does not contain test

 

data and has an undefined workflow. When

 

the workflow is defined, it can be extracted by

used to collect data and contains a copy of the

 

template. Each time you run the template on

 

a physical specimen, the application creates

 

a test run. The test run is a data set that

 

populates the test.

 

Note:

 

Only templates that are licensed appear

 

in the New Test from Template list.

New Test from Existing Creates a new test that includes a copy of the

Test test without test run data.

New Test from File Creates a new test from an XML file; typically used in automation.

3.2.3.0 Test Activities Overview

Test activity sequence

Test activities execute from top to bottom in the order in which they appear on the Procedure tab. To execute activities simultaneously, add Parallel Path activities to the test flow. You can also add While Loop, If-Else Condition, and Periodic Time Event activities to control the test flow.

Test activity property definition

To define the properties of an activity, select the activity icon on the Procedure tab, and then click the Properties tab.You can choose to define properties as fixed values or variable values. The following example shows the property definitions for a Cycle test activity.

3.2.3.1.0 Deleting and Disabling Test Activities

If you want to remove a test activity from the test procedure, you can either delete the test activity or disable the test activity.

When you delete the activity, the activity is permanently removed from the test procedure. This action cannot be undone, and you will have to either recreate the test activity or revert to a previously-saved version of the test that contains the activity.

If you do not want to delete a test activity, but you also want to temporarily prevent the activity from occurring during a test run, you can disable the activity. When you disable a test activity, the test activity becomes grayed-out in the test procedure and the activity is ignored when the test is run. After you disable an activity, you can enable the activity and it will once again occur during test runs.

You may find it helpful to temporarily disable some test activities when you are creating a test or when you are troubleshooting suspected problems in the test. For example, you can disable certain portions of the test in order to focus your time on a few specific test activities that you believe are causing problems. Alternatively, if you want to remove a troublesome test activity, but you are unsure of the impacts, you can temporarily disable that test activity and replace it with a modified activity and perform a test run to view the results. If you determine that you do need the disabled test activity, you can later "retrieve" the test activity by enabling it.

To delete, disable, or enable a test activity, right-click the test activity and select Delete, Disable, or Enable (if the test activity is currently disabled).

3.2.3.2.0Variables Overview

Typically, when you enter a value for a property in an activity, you can change the value only when the test is stopped and the test procedure is unlocked. In this sense, the property is “fixed.”

With the use of variables, you can associate a property of an activity with a variable.This allows you to change the variable value without selecting the activity.

For example, suppose you create a test procedure that includes several command activities that all use the same frequency. Rather than enter a frequency value for each activity separately, you could associate all the frequency properties with a “Frequency” variable. Then, between tests (with the test stopped and the test procedure unlocked), you could use the Variables Editor to change the frequency value of all the activities at the same time. For more information about the Variables Editor, see the Multipurpose Elite User Guide. The following example shows how to make the Frequency property of the Cycle activity a variable.

Variable use in MTS TestSuite software

MTS TestSuite software uses variables extensively throughout its applications:

22 Multipurpose Elite Test Design Guide

3.0 Designing a Test

The MPE application uses variables to simplify test creation and modification, allow operator interaction in the test flow, and facilitate monitor display.

The MTS TestSuite Reporter Add-In for Microsoft Excel uses variables to capture test data for test reports.

The various MTS Analyzer applications use variables to create “what if” scenarios using specimen variables and data from test runs.

Test activities and variables

The MPE application allows you to define many of the individual properties of test activities as variables. The MPE application also includes test activities you can use to manipulate variables in the test flow, as follows:

Assign Variables activity

Calculate Variables activity

Input Parameters activity

You can use these activities in a variety of ways to manipulate variables. For example, you can use an Input Parameters activity to allow the operator to change variable values while the test is running.

Adding calculations to variables

You can add mathematical operators to variables to create calculated variables.You can do this in two ways, depending on test design considerations:

Click the Variables tab in the main window to add calculations to individual variables.

Add the Calculate Variables activity to the test procedure. This activity allows you to add calculations to variables in the test flow.

Adding and editing variables

You can add or edit variables from within the various variable editing windows and editors (such as the Map Variables window or the Calculation Editor). You can click the Add Variable (green plus sign) or Edit Variable (...) icon or right-click and select New Variable. To edit a variable, right-click a variable name and select Edit Variable.

3.2.3.3.0 Information for an Operator

You can add information for an operator, such as hardware installation instructions or safety information, directly into your test design. This allows you to create the information visible to the operator during the test, and control at which point in the test flow to show the information.

To do this, add special test activities and run-time devices to your test.

The Custom Message Window activity allows you to show a custom message to the operator anytime the test is running.

The Run External Application activity allows you to show documents that require external applications to launch, such as word processing, spreadsheet, and video documents.

The Custom Help monitor display allows you to show custom help information, such as files in the .chm file format, that you create for the test.

When you start the test, you can see real-time test information on the Test-Run Display panel.

Add monitor display devices

To add monitor display devices to your test, click the Test-Run Display tab and drag monitor display devices from the toolbox to the work area. When you do this, error icons on the device icon and Error list guide you to define required properties. The following example shows a Signal Scope device, which simulates an oscilloscope on the Test-Run Display tab when the test executes. To view its properties, you select the Signal Scope device on the work area.

3.2.5.0 Test Execution Overview

Using Station Manager with TestSuite software

The Station Manager application runs in the background alongside the MPE application. When you design or run tests with the MPE application, minimize the Station Manager application to simplify your PC desktop.

The activities that an expert user may perform with the Station Manager application varies with your station and test setup, but typically includes:

• Design and use profiles. This is done using the optional Profile Editor in the Station Manager application.

Install new hardware resources. This is done using the Station Builder tool in the Station Manager application.

Adjust commands settings (such as ramp and taper times). This is done using the Channel Options tool in the Station Manager application.

Access the values of calculation parameters and variables. This is done using the Calculation Editor in the Station Manager applicationr.

Set limit levels and actions for detectors.

Position the actuator to install the specimen.

Apply offsets.

You can perform some station activities with the Multipurpose application, such as:

Energize and de-energize actuator power.

Reset and override interlocks.

Start, hold, and stop tests.

Perform Park, Unload, and Stop At operations.

Other station activities you may perform with Station Manager

You can perform some station activities pre-test or between tests, such as:

Check shunt calibration levels

Adjust tuning values

You can only perform these activities with the Station Manager application.

Test execution with the MPX application

Similar to the MPE application, the MPX application can be used to run tests. However, the MPX application cannot create or modify tests. In order to create or modify tests, you must use the MPE application.

Considerations for automatic background saves

It is important to keep in mind that when you start a test run, the application automatically saves the current state of the test. If you need to modify a test without necessarily saving your changes; that is, experiment with the test, you should perform a Save As of your test, modify as required, and then run the new test.

If you inadvertently run a modified test and have to undo the changes you made to the test before you ran it (and the application automatically saved it), you must do so manually.

3.2.6.0 Model 494.05 Handset Station Activities

If your station is equipped with a Model 494.05 Handset, you can use it to:

Manually position the actuator to install the specimen.

Apply offsets.

Note:

You cannot use the handset to set limit levels and actions for detectors. Perform these activities with the MTS Station Manager application.

4.0 Working with Resources

4.1.0 Resources

With the MPE application, you create test designs that cause controller resources to apply desired forces to your test specimen. Controller resources include control channels, control modes, sensors, digital inputs, and so on.

For example, suppose you design a test to apply a tensile force to your specimen and receive a digital pulse when the specimen fails. When you run the test, the controller uses a control channel with a force control mode resource to apply the tensile force to the specimen, and a digital input resource to receive the digital pulse.

Controller resources

A controller resource refers to a hardware resource in the controller as it appears in a station configuration file. For example, a control mode in a station configuration file named “axial force” is a controller resource.

Test resources

A test resource refers to a resource with equivalent functionality as it appears in the test definition. For example, a control mode in a test definition named “load 1” is a test resource. You can use test resources for various test elements, such as activities, monitor display devices, and variables.

Resource mapping

A test resource is not required to have the same name as the equivalent controller resource. However, if the names are different when the MPE connects to the station, you must map the test resource to the equivalent controller resource.

For example, suppose you design a test offline in which you name a control mode “load 1”. Later, you connect to a station in which the equivalent resource is named “Axial Force”. This mismatch of resources creates a resource validation error. To resolve this error, you must map the test resource to the controller resource.

4.2.0StartingMPEandConnectingtoaController

Controller resources are available to the MPE application through station configuration files. Before you start the MPE application, you typically start the MTS Station Manager application and open a station configuration file first. When you start the MPE application, it automatically connects to the station configuration, which allows you to design tests with the resources in the station configuration. If you do not already have one, you can create a desktop shortcut that will open the MTS Station Manager application and then open the MPE application. For more information about creating that shortcut, see Creating a Desktop Shortcut That Includes a Controller on page 18.
