Perception Software 64-bit
Perception 8.60
This is a major release of Perception. Fixes::
Averaging in Spectral Display always Peak hold average
In the Perception Spectral display, the averaging was always peak-hold rather than the selected linear or exponential. This issue is fixed such that now the proper averaging is done. Fundamental calculation issue on RT-FDB
A problem with cross-board cycle signals used for doing fundamental calculations was solved. Change of conditional Start/Stop time does not work during the recording
In Perception it is possible to conditionally start or stop a recording. Up until now it was possible to change the conditions during a recording which might lead to unexpected or undefined situations. In this release it is no longer possible to change conditions during a recording such that the conditions are always well-defined. Graphical problem in Report sheet tables in Perception
A problem with columns width when automatically generating a report was solved. User defined display color is not permanent stored
User-defined colors are now stored as part of the PC settings. Switching display mode to ReviewSweep does show the full recording instead sweep
A problem with switching between Review and ReviewSweep in the time display was solved. Using macro function auto scale active display y-axis is takes only action on first page of the display
The macro function auto scale active display y-axis now works on all pages of a display. The format of the displayed value in a marker does not reflect the format set in Properties for the marker
A small formatting discrepancy between marker field and the properties of a marker was solved. Suppress overrange drawing does not work as expected
Some related issues concerning drawing or suppressing overrange data where solved. Trace marker not connected to trace line
A trace marker is now always connected to a trace. Load Settings menu option doesn't load workbench settings completely
A problem with incomplete loading of working bench settings was solved. Apply a Thermocouple type C sensor, Perception shows type B
A thermocouple type C sensor is now shown as such. Redo an existing Experiment and load existing Experiment data does not include data
On opening Perception and selecting 'Redo an existing experiment and load existing experiment data', the data was not always loaded. This problem is solved. Recordings got locked up by Perception
When a recording is finished, it is unlocked and can be accessed by other software. Sometimes the recording was not unlocked and this problem is now solved. No MDF4 file when exporting using automated processing
The problem of a missing MDF4 file when exporting using automated processing was solved. Sluggish behavior when loading a virtual workbench
In some case, Perception could react in a sluggish manner when loading a virtual workbench. This problem is solved. NEW Features:
Add hardware settings to a recording stored on a mainframe
Up until now, when a recording was made by storing all the data directly on the internal disk of each mainframe (as opposed to storing all or some of the data on PC), the hardware settings of each mainframe were not available in the recording. In the new release, it is possible to include the hardware settings of a mainframe in the recording written to the mainframe's internal disk, in order to know exactly how a recording was made. Automatic merge of mainframe data
In the GHS/Perception system, it is possible, and sometimes necessary, to store a recording partially or completely on the internal disc of a GHS mainframe. In this release it has been made possible to automatically merge the different parts of a recording into a single recording file on a PC. An additional improvement in this context is that the speed of transferring a recording from a mainframe to the PC was increased by a factor 2. Rework of the Spectral Display including new features such as: - Selection of signals in the time domain Display for which spectrum is shown.
- Display of near-real-time spectra in Review while recording.
- Adding individual spectra one at a time to the average in Review mode, making it possible to see how the average changes over time.
- Choice of cursor colors making it easier to link time intervals to spectrum in the new Spectral Display.
- Addition of the Kaiser-Bessel window possible for time domain.
- Display of spectra as A-weighted useful for spectra related to sound signals.
In the Measurement Uncertainty sheet, support for new hardware was added The measurement uncertainty (MU) of a measurement depends on the properties of the used hardware (sensors, acquisition cards, etc.) which should be incorporated in the MU calculations. In the Measurement Uncertainty sheet, support was added for the T12 w-version torque sensor (but not yet for the minimal torque value of 100Nm). Furthermore, support for the GN610B/GN611B acquisition card was added, as well as support for burden resistors to allow for measuring both voltages and currents with those cards. Allow publishing any value on the fieldbuses in case of an invalid signal
Since not all external systems can easily handle NaN, it is now possible to select a user-defined value to publish when a signal is not valid. Allow triggering of signals in Live display based on cycles:
In the Live display in Perception, signals are often not stable but 'running', just like in an oscilloscope that is not triggered. In the new release, it is possible to trigger signals based on cycle signals. Periodic signals related to a selected cycle signal will then be stable in the Live display. NEW ePower Suite Features::
Using field bus signals, allow easy detection if a setup is in steady-state
A setpoint of an eDrive setup (e.g., the efficiency for a certain torque/speed combination), is commonly measured when a system is in steady-state. In the new release, additional RTFDB functions can be instantiated by the ePower suite which, for a number of relevant signals, determine the mean and standard deviation. The user can determine how the samples to determine if mean and standard deviation are selected in terms of a specified number of samples or as a time interval. NEW Features for Hardware::
XCP over Ethernet
This is the first major release which will support “XCP Over Ethernet” in our mainframes. This release supports the functionality of “XCP Over Ethernet – Output” which means data from the mainframe (slave) can be read by the master via XCP. In Perception, Real time data -> Publishing , a new column “Publish to XCP over Ethernet” will be available to allow publishing like existing fieldbus. For generating the A2L file, “Save A2L file as…” button is available. Known Limitations for 8.60 release: - This has been tested using CANape ONLY.
- There are known issues with ETAS Inca and is being worked upon for next minor releases.
- This is NOT supported for integrated systems.
Mainframe control via EtherCAT PDO This is the first major release which will allow mainframe control via EtherCAT PDO. On EtherCAT, several communication protocols are available. Up until now, GHS provided Remote Control via EtherCAT CoE (CAN over EtherCAT), but only SDO as the supported mechanism. From this release onwards, PDO will be supported as well. FieldBus Remote Control documentation may be referred for more information on the available commands and how to use them and return code description. Improvements in Perception ::
Modernized the look-and-feel of Perception
Many of the icons and graphics were updated to give a more modern look-and-feel and to improve usability. Prevent large MatLab/MDF4 export files due to asynchronous signals
In the new release, when exporting signals from Perception to Matlab or MDF4, it is now possible to export asynchronous signals as asynchronous signals, or resampled at a lower user-defined sample rate leading to significantly smaller file sizes for those formats. Improve how a user can see and print the hardware settings from a recording
Up until now, hardware settings of a recording could be printed by loading a recording as Active, and then selecting Settings. Two additional entries are shown in the Print sub menu to make this easier: 'Settings from active recording...' and ' Settings from current settings...' . Report CAN signal definition errors in Perception:
When a wrong definition of the setup of CAN channels is provided, Perception now gives an error message such that the setup can be corrected. Add key-mouse combination for temporarily grouping of cursors:
Currently the user has the option to group/ungroup cursors by pushing a button in the menu bar. To improve usability it is now possible to press the Alt-key, drag one of the cursors and the related cursors will move as a group. This works for horizontal, vertical and slope cursors. Improvements for Hardware::
Allow for unsigned/signed 16-bit CAN inputs
Next to 32-bit and 64-bit signed and unsigned CAN signals, we now also allow for 16-bit signed and unsigned CAN input signals. Allow integrating asynchronous samples
Up until now, the IntegrateGated() function could only handle synchronous signals to be integrated (such as instantaneous electrical power) but not asynchronous signals which are used, for example, to describe the instantaneous mechanical power. From this release, this function can also handle asynchronous signals. Additional CAN sample rates
In previous releases, all CAN input signals to a GHS mainframe were sampled at a rate of 100S/s. It is now possible to choose a different sample rate for each CAN recorder. When choosing a higher sample rate, the maximum number of allowed channels is reduced. The constraint is that the sum, over all CAN recorders, of the product of the sample rate and the number of channels should be lower than 100,000. Some feasible examples are as follows: - 1000 channels at 100S/s
- 500 channels at 200S/s
- 200 channels at 500S/s
- 100 channels at 1000S/s
- 40 channels at 2500S/s
- 25 channels at 2500S/s, and 30 channels at 500S/s, and 15 channels at 100S/s, and 75 channels at 100S/s.
