About Projects About Projects Understanding Projects A Series 793 Project folder (or Project for simplicity) contains the various types of information you typically acquire while testing. Project 1 Project folders contain various files centered around test design and test execution. Projects also contain settings that include references to common support file stored elsewhere (as shown to the right). Project folders are displayed with a double-red line notation.
Understanding Projects Projects include information: Benefits of Projects Your initial Project • Required to perform tests, such as configuration files and test design files; and • Generated by testing, such as test data, scope images, and specimen files. • Captured as a result of unexpected shutdowns (Shutdown Recorder directory) The Project Manager (and the ability to create Projects) became available in version 4.0 of Series 793 System Software.
Using Project Manager to Modify Projects Using Project Manager to Modify Projects Every Project contains a Project Settings file. Most Project settings are folder path specifications. To configure Projects, you use the Project Manager application to edit the Project Settings file. A Project Settings file acts like a switchboard that directs the flow of information within a Project.
About Hardware Interface Files About Hardware Interface Files Understanding Hardware Interface Files The resources in your Station Builder application resource lists are defined by the hardware interface file (or .hwi file) installed with your system software. Resource examples include conditioners, valve drivers, digital inputs, and so forth. The .
Understanding Hardware Interface Files Editing .hwi files with the Hwi File Editor MTS has a software utility for editing .hwi files, called the Hwi File Editor. This utility minimizes the chance of introducing syntax errors when making changes to existing .hwi files or creating new .hwi files. The built-in logic of the Hwi File Editor streamlines the process of adding new resources. For instance, when you add or remove analog resources from an .hwi file, the .
About Station Configurations About Station Configurations About the Station Builder Application The Station Builder application defines the parts of a station configuration from a pool of system resources listed in the hardware interface file. With the Station Builder application, you can allocate all or a portion of your system resources to create station configuration files.
Using the Station Builder Application to Create Using the Station Builder Application to Create Station Configurations When you create station configurations with the Station Builder application, you are not required to apply power to your station or handle station hardware--you are simply creating files.
Station Builder Application Window Station Builder Application Window The Station Builder application has one main window that enables you to create station configurations.
About Assigning Parameters to Station About Assigning Parameters to Station Configurations About Parameter Sets In the pretest phase, you use the Station Manager application to optimize how the parts of your system work together. A product of the pretest phase is a parameter set that you save with the station configuration. A parameter set adapts the way the resources in your station configuration operate to suit your test requirements. Parameters include everything from tuning values to detector settings.
Using the Station Manager Application to Create Using the Station Manager Application to Create Parameter Sets When you optimize your station configuration with the Station Manager application, you perform many of the activities required to perform a test: You apply power to the station, manually position the actuator, apply tuning programs, monitor waveforms, and so forth. While doing these activities you adjust parameter values accordingly, which you save with your station configuration.
Using the Station Manager Application to Create To complete this task, make sure the force tuning values established in your parameter set are suitable for the test you are about to run.
Using the Station Manager Application to Create Where parameter sets are stored A station parameter set is not a discrete file that you can see on your desktop. It is a discrete attribute set that is saved within a station configuration by the Station Manager application. By default, configuration files are located at C:\MTS 793\Controllers\Controller Name (for example, FlexTest GT)\Config. Configuration files are referenced from the Project you selected when you started the Station Builder application.
Station Manager Application Windows Station Manager Application Windows With the Station Manager application, you can perform the following to optimize your station configuration prior to running tests.
About Compensators Station Setup window About Compensators Compensators are control techniques that improve the tracking and accuracy of your controller. They play an important role in optimizing system performance. Various compensators are available to suit specific test requirements. Null Pacing Null pacing ensures that desired levels are achieved on the initial command pass without over programming the input.
About Compensators Amplitude and Phase Control (APC) The Amplitude and Phase Control (APC) compensator monitors feedback from sine and sine tapered commands for amplitude roll-off and phase lag. APC works well when you need to control the amplitude of the fundamental frequency component.
About Compensators AIC is typically used in tests on linear specimens in which road profiles developed on a separate system must be accurately reproduced without having to iterate. AIC is also used on fast sine sweeps, particularly when the sweep rate is too fast (>1Hz/s) for APC, and on any component being tested with random or time history signals on a linear system.
About Compensators ALC is typically used in matrix depletion fatigue tests where only one or two cycles of a particular amplitude are executed before new amplitudes are introduced. Example of feedback dropping off in a test waveform without ALC compensation. The same waveform with ALC compensation Adaptive Harmonic Cencellation (AHC) Adaptive Harmonic Cancellation (AHC) works with Amplitude Phase Control (APC) to minimize spurious harmonic distortion.
About Compensators Adaptive Harmonic Cancellation is typically used when programming with pure sinewave commands or sine sweeps in acceleration control. Also, ALC is typically used in high-frequency MAST systems for ground vehicle testing. How AHC Works Because cancellation occurs at the system output by means of a signal at the system input, the phase response of the system must be known.
About Test Designs About Test Designs Understanding Test Design Files MTS Series 793 Software offers several applications you can use to create test design files. When you save test design files, they are automatically stored in the current Project. Note The Basic TestWare application is the only test design application that comes standard with Series 793 Software.
Designing Tests with the Basic TestWare Application Designing Tests with the Basic TestWare Application The Basic TestWare application is included in the Series 793 System Software bundle, and is the easiest software tool for creating simple monotonic and cyclic test designs that do not require complex signal management or mode switches. An on-screen panel lets you create tests by defining the rate, frequency, amplitude, and mean for sine, triangle, square, and ramp command signals.
Designing Tests with MultiPurpose TestWare Designing Tests with MultiPurpose TestWare MultiPurpose TestWare (MPT) is a powerful and flexible application that enables you to quickly and easily define complex test designs. MPT allows you to create complex test designs with discrete processes. Each process represents an individual test activity. This diagram shows how a test waveform may correlate to individual process icons.
Designing Tests with MultiPurpose TestWare Types of information in MPT test procedures Working with Processes An MPT test procedure contains two types of information: • Process information, which defines your processes (command, data acquisition, signal monitoring, and so forth) and the sequence in which each process executes • MPT application information, which includes test unit and dimension assignments, the behavior of hold and resume functions, the data file format, and so on You begin designing
Designing Tests with MultiPurpose TestWare For example, suppose you create a test procedure that includes several command processes that all use the same frequency. Rather than entering a frequency value for each process separately, you could associate all the frequency parameters with a “Frequency” variable.
MPT Process Types MPT Process Types Command Processes ICON PROCESS NAME DESCRIPTION Segment Command Produces a monotonic command signal. Cyclic Command Produces a cyclic command signal. Dwell Command Produces a dwell (or hold) command signal. Profile Produces a command signal based on the contents of a “profile” created with a text editor or the Profile Editor application. External Command Enables a command signal from an external program source.
MPT Process Types Data Acquisition Processes ICON 70 PROCESS NAME DESCRIPTION Peak/Valley Acquisition Records the peak/valley data for each cycle execution. Timed Acquisition Records data at user-specified time intervals. Max/Min Acquisition Records data at the highest peak and lowest valley during the life of the process. Level Crossing Acquisition Records data each time the selected signal changes by a specified amount. High Speed Timed Acquisition Records bursts of data at a high rate.
MPT Process Types Event Processes ICON PROCESS NAME DESCRIPTION Data Limit Detector Monitors one or more signals for sensor limits you specify. Digital Input Detector Detects digital transition states from external devices. Operator Event Enables operator interaction during the test. (For example, Operator events can display buttons the operator must click to continue the test.). Peak/Valley Change Detector Detects changes in the peak and valley amplitudes of cyclic waveforms.
MPT Process Types Other Processes ICON 72 PROCESS NAME DESCRIPTION Program Control Performs user-defined program actions such as Program Hold, Program Resume, Interlock, and user defined actions. Group Defines a process sub-group that can contain one or more other processes. MPT Calculation Adds mathematical functions to variable parameters. Operator Information Enables operator data entry (to be written to a data file) during the test.
MultiPurpose TestWare Windows MultiPurpose TestWare Windows MPT control panel The MPT control panel appears in the application area of the Station Manager application, as shown. MPT main window is nested within the Station Manager application main window. When you select the MPT application from the Station Manager application, the run, stop, and hold controls on the Station Controls panel pertain to running MPT test procedures.
MultiPurpose TestWare Windows Procedure Editor The MPT Procedure Editor contains a table on which you build MPT test procedures by selecting, assigning parameters to, and sequencing individual test processes. Test processes represent individual test activities. Navigation pane Status and progress indicators A blue arrow pointing toward a process (not shown) indicates it is executing. This lets you watch the progress of a test.
MultiPurpose TestWare Windows Process Palette The Process Palette displays the types of processes you can drag to the Procedure Editor. Process Palette Individual processes are arranged on the palette by type. You can double-click a process on the Process Palette to copy an instance of it to the table on the Procedure Editor, or you can use the drag-and-drop method.
About Running Tests About Running Tests Understanding Files Used for Testing During the testing phase, the Station Manager application controls how the parts of the system work together to maintain precision servo control. Command is typically provided by an application such as Basic TestWare or MultiPurpose TestWare.
Test Desktop Test Desktop With the Station Manager application window controls, you can perform the following to run tests: • Load and reload stations • Configure limit and error detectors • Control hydraulic pressure to the test station • Manage the execution of the Basic TestWare and MultiPurpose TestWare applications • Monitor signals on the built-in scopes and meters Windows typically open while running a test.
Monitoring Test Information The Scope displays the waveforms of selected signals. Monitoring Test Information MTS Series 793 Software includes several features for monitoring test signals and test progress. MPT Counters 78 Run time counter The Run Time counter displays the elapsed time of the current test since the last time it was reset. Channel counters Channel Counters display a cumulative count of segments or cycles that have been applied to a specific channel since the start of the test.
Monitoring Test Information Sequence counters Sequence Counters display the progress of individual processes within the test. They can be especially useful for procedures that contain nested groups, because you can configure them to show test progress within the nested structure of the procedure. This sample procedure includes a group process labeled “Cooling Cycles,” which contains four nested processes (with indented label names, “Trigger at 75C,” and so forth.
Monitoring Test Information Meters display The Meters window can display up to 16 meters per station simultaneously. The following data can be displayed for any defined input signal: • Timed data • Peak/valley data • Mean/amplitude data • Maximum/minimum values Meters can be aligned on the desktop vertically, horizontally, or in a grid. Meter displays can be sized to your preference. Scope display The Scope window in the Station Manager application is an oscilloscope.
Monitoring Test Information When you place the cursor on the trace, it becomes a crosshairs. With the crosshairs, you can select individual data points on the trace and see their precise coordinates on the axes in the associated display box.
