Perception 8.28

This is an minor release of Perception mainly improving stability, fixing known problems and adding minor new features.

This is not shipped out with the hardware but only available via web download.

Details about fixed issues and new features can be found in the release notes.

Note: Perception includes the instruments firmware for GEN DAQ systems. So there is no separate firmware available for GEN DAQ systems.

When you connect to hardware using a new version of Perception, the firmware in the hardware will be upgraded accordingly to the same release level.

Perception 8.30

This is a major release of Perception: We strongly recommend to update all Perception 8.22 installations to Perception 8.30, due to important bug fixes.

Note : Before you can upgrade to Perception 8.30, you must upgrade to Perception 8.28 first!

This step is required due to changes to the update mechanism

Harmonic Analysis

Functionality has been added to calculate and display harmonic information according to the IEC 61000-4-7 standard. This standard specifies how harmonics must be calculated for signals with a 50Hz or 60Hz fundamental frequency which typically appear in power grid and power line applications. This new functionality contains the following parts. A new RTFDB function is now available called HarmonicsIEC61000 which calculates the spectrum of a signal following IEC 61000-4-7. The resulting harmonics can be made visible in a new Harmonic Analysis Display in Perception, both in graphical and tabular form. Harmonic Analysis is also fully integrated in the ePower suite as an optional analysis where it comes with several ready-to-use grid application setups. The Quick Start Guide for this new functionality is part of the documentation that comes with the installation and is also available from the Perception website.

Measurement Uncertainty

Perception Enterprise now contains a dedicated sheet to calculate the Measurement Uncertainty (MU) of DC, AC, and mechanical power values. Given inputs like the measured AC power, the type of acquisition card used, and the type of transducer used, this MU Estimation (Basic) sheet calculates the absolute and relative MU of the measured quantity. If the sheet is not visible, in Perception choose from the menu bar Sheets and then ‘MU Estimation (Basic)’. Once the sheet is loaded, the Quick Start Guide can be found by opening the context menu of the sheet's tab and choosing Quick Start Guide...

EtherCAT Distributed Clock

The Genesis mainframes support EtherCAT Distributed Clock to synchronize the internal clock with the EtherCAT clock.

RTFDB number of channels available for storage

The number of RTFDB channels available has be improved. The number of RTFDB channels available for storage has been increased to the table below.

Mainframe type | Available number of RTFDB channels for storage before | Available number of RTFDB channels for storage, after update

GEN2tB | 256 | 256

GEN3t / GEN3i / GEN3iA | 256 | 300

GEN4tB | 256 | 500

GEN7t / GEN7i / GEN7iA | 256 | 1000

GEN17tA | 256 | 1000

Perception 8.40

This is a major release of Perception

Inversion of analog signals

The polarization of the signal can be inverted for GN61xB, GN31xB, GN120xB, GN1640B, GN840B and GN810xB

Support for the measurement uncertainty of efficiencies in the Measurement Uncertainty sheet

The Measurement Uncertainty sheet now also allows calculating the uncertainty in efficiencies based on the uncertainties calculated for the DC, AC and mechanical power numbers. The efficiencies and their measurement uncertainty can be made visible by clicking the dotted button at the bottom of the sheet, by choosing the eta symbol in the Perception toolbar, or by right-clicking the 'MU Estimation (Basic)' tab and selecting 'Show Efficiency Calculation Results'. If the Measurement Uncertainty sheet is not visible, in Perception choose from the menu bar Sheets and then ‘MU Estimation (Basic)’. Once the sheet is loaded, the Quick Start Guide can be found by opening the context menu of the sheet's tab and choosing Quick Start Guide... .

EtherCAT control

The GHS mainframe settings and acquisition control can be controlled via EtherCAT. The protocol and commands are the same as CAN remote control. Sending command SDO triggers execution of the command with provided parameters.

New functions for mean and standard deviation in the

Several new functions were added to the Real-Time Formula DataBase (RTFDB) related to determining the average and standard deviation of signals. The first new function is CycleStdDev(). and forms a pair with the exisiting CycleMean() function: where the CycleMean() function determines the mean (or average) over all samples between two cycle events, the CycleStdDev() calculates the standard deviation over the samples. We further introduce the pair of functions TimedMean() and TimedStdDev(). Those functions repeatedly calculate the mean and standard deviation, repectively, over a user-defined time interval. For example, if the user-defined time is set to 1 second, every 1 second, a mean (or standard deviation) for the input signal will be generated over the previous 1 second. The next new pair of functions is NumSamplesMean() and NumSamplesStdDev(). Those functions repeatedly calculate the mean and standard deviation, repectively, over a user-defined number of samples. For example, if the user-defined number of samples is set to 10, for every 10 samples of the input signal, a mean (or standard deviation) will be generated over the previous 10 samples. It is important to note that the outputs of the last four functions cannot be used as the input of another RTFDB function, but they can be published on the fieldbuses. With the proper setup, the standard deviation functions, possibly in combination with the corresponding function for the mean, make it possible, for example, to get an indication on the field buses if a system is in steady state.

Fixes:

In some special situations, not all setpoints were stored in the setpoint table. This is now solved. (solves SUPEPT-253)

A problem with applying a virtual workbench to an identical but different mainframe. (solves SUPEPT-257)

In some situations it could happen that modifications made in Perception were not saved in a virtual workbench. This problem is now solved. (solves SUPEPT-261)

A problem with restarting a mainframe with specific user settings was solved. (solves SUPEPT-256)
