MCO 305 Design Guide__ APOSS Tools __118 MG.33.L5.02 – VLT® is a registered Danfoss trademarkTESTSETP OscilloscopeThe TESTSETP Oscilloscope is designed to display user-defined TESTSETP arrays created on the controller(i.e. with the TESTSETP command). As with the Single Shot Oscilloscope, values are recorded using aTESTSETP array and uploaded to the Oscilloscope after the test is complete. However, the TESTSETPOscilloscope relies on users configuring their own TESTSETP arrays from within their application programs.The arrays are not automatically configured by the Oscilloscope; the Oscilloscope simply reads alreadyexisting TESTSETP arrays that have been created by the user's application.The TESTSETP Oscilloscope is useful in the following situations:– Applications where the user has created a customized TESTSETP array from within the applicationprogram. This includes the use of multiple recordings within a single TESTSETP array.– Testing controllers that contain firmware that is too old to support the automatic configuration ofTESTSETP arrays. In this case, the Single Shot Oscilloscope cannot be used.Since the TESTSETP Oscilloscope simply reads existing arrays, there is no need to start and stop recording.Hence, the TESTSETP Oscilloscope operates slightly differently from the Single Shot and Free RunOscilloscopes. The steps are as follows:1. Before the TESTSETP Oscilloscope is started, the user must execute an APOSS program that recordsthe desired data using the various TESTSET commands. This program can be started in the normalway by using Development → Execute [F5].2. After the test has been completed, the TESTSETP Oscilloscope can be started. The TESTSETPOscilloscope will then automatically attempt to read the TESTSETP array from the controller.NB!:In previous APOSS versions this functionality was available using the Testrun → Display recordingmenu command. Starting with MCO 5.00, “Display recording” has been replaced by the TESTSETPOscilloscope.The TESTRUN functionality that existed in previous APOSS versions, allowed the results of Execute testrunand Display recording commands to be saved in “.txt” files. These old “.txt” files can still be read anddisplayed by newer versions of APOSS. See Reading Old Testrun Files.Tune OscilloscopeThis Oscilloscope is designed to assist the user in “tuning”, or optimizing, the controller's internal para-meters. This is a necessary step for ensuring the best and smoothest possible performance of the controllerin each specific application.NB!:In previous APOSS versions this functionality was available using the Testrun → Execute testrunmenu command. Starting with MCO 5.00, “Execute testrun” has been replaced by the “TuneOscilloscope”.
