• Power module rework with major speed improvement (SP1)
• Steps recorder for bug reporting
• Setup lock to a license allows system integrators to sell setups
• Encryption of setup and data files
• Multithreaded trigger allows faster calculation (each condition has it own thread)

NOTE: Dewesoft X3 is fully backward compatible and will read setup and data file from X2 version.

DEWESoft X3 is now available in a 64-bit version

For the first time in its history, Dewesoft software is also available in a 64-bit version. This allows DEWESoft to take full advantage of the resources that are physically available in modern computers. Users can expect better performance in large-scale applications and be able to use more channels and math modules, more memory, export more data at once and have a clearer overview of signals on visual controls.

Recommendation: use X3 - 32 bit version whenever it’s possible, in special cases (for example with lots of channels) use X3 - 64 bit

Modern flat design, with an even more intuitive user interface

The user interface has been reworked in order to make the program feel more modern and user-friendly. Apart from the robust visuals, major improvements have also been made in the grid system, which has been unified across the standard modules. The so-called »DSGrid«, which was already available in »Channel setup«, offers a comprehensive overview of channels, gives the user a range of customization options and offers a wide array of convenient shortcut features.

Improved graphs and better tick marks and axis for better handling

The entire visual control settings tab has been redesigned and features new display options, which improve the readability of data and make displays even more configurable to satisfy every user’s needs. The recorder has received a major upgrade, now being able to display the time axis as a continuous stream of equidistant time stamps, rather than just showing statically placed time varying points. In addition to that, “pinch to zoom” has also been added, making DEWESoft a bit easier to operate for touch screen users. Regular users that control DEWESoft with a mouse and keyboard will find that they can now drag the signal up and down the y axis, scale the signal using the scroll wheel and have multiple channels auto scaled on the same visual control, which wasn’t possible in the past.

POWER MODULE

Power module rework with major speed improvement and improved NET interface with flat list for analog channels add convenience and guarantee a better user experience!

The power analyzer have seen drastic improvement. The power module is now easier to use, due to its redesigned user interface, while at the same time being less performance heavy and featuring advanced computational algorithms. X3 is more than 10 times faster than X2 in most configurations.

With three phase power module and all options enabled Dewesoft X3 can calculate power module with 600 ks/sec while Dewesoft X2 speed with is 50 ks/sec.
When disabling current flicker, which is very specific to grid measurements, a three phase module can be calculated in Dewesoft X3 speed with full speed 1 Ms/sec, two three phase power modules can be calculated at 800 ks/sec. For the reference Dewesoft X2 speed with 1 power module is 200 ks/sec.
The performance was measured on SBOX2 + SIRIUS HS.

The power module is used more and more for high speed inverter measurements, driven by hybrid and electrical vehicle development. The inverters speed can change very fast, for example from start to full speed in ten seconds. Dewesoft X3 can handle this high variation of frequency as shown on the screenshot below. This along with a chance to acquire all other vehicle parameters makes Dewesoft power instruments perfect for e-mobility measurements.

Devices support

DEWESoft X3 supports new devices and implement device functionality which will make everyday measurements even easier and more enjoyable.

Devices improvements:

• Ethercat speed boost makes Sirius Ethercat even more attractive with 200k sampling on USB AI and CNT with different rates (SP1)
• Parallel TEDS reading allows faster scans
• Buffered mode for Krypton DI devices
• Unbuffered mode for Krypton and Sirius devices allows users to connect to third party master
• Buffered mode for CAN devices on transmit in measure mode
• New GiGE camera driver/new 600fps camera firmware a must-to-have upgrade
• NTP and GPS sync for Sirius Ethercat and Krypton devices
• Safe mode for dual mode doesn’t allow stopping devices when in control mode
• Offline setup for Krypton modules (SP3)
• New devices support for Krypton 4xDI (SP0), Krypton 1xAO (SP0), Krypton 4xDO (SP2), Krypton 1xACC (SP3), Krypton 4xACC (SP3)

Ethercat Speed boost

On the EtherCAT side of the instruments, »speed boost« can now be used on multiple SiriusE devices, which allows faster sampling on your already existing EtherCAT chains. If you connect any SiriusE device in an EtherCAT chain with a USB cable as well, that unit will be able to store data with 200 kS/s, while remaining in perfect sync with the rest of the devices in that chain.

Unbuffered mode for Sirius and Krypton devices allows users to connect to third party master

Sirius Ethercat and Krypton devices are now proven and tested as standard Ethercat slave which enables them to connect to any third party Ethercat master. In fact, that makes Krypton really unique - with lossless buffered acquisition and perfect Dewesoft support making it ideal for data acquisition and on the other hand as standard Ethercat device, such as Beckhoff Twincat, Acontis Ethercat master or others.

Parallel TEDS reading allows faster scans

With the bigger systems like R8 with 8 slices the scan of TEDS could take up to 20 seconds. X3 scans all the slices in a single run reducing the scan time by a factor of eight as if you would have one single device.

Counter channels can operate with reduced rates

Sirius devices can acquire the data from various sources - analog, digital, counter, CAN. The so called master sample rate is used to set the speed of acquisition fo all these channels. So far the users were able to reduce the speed for analog channels on a channel-per-channel basis (master rate would be 200kHz, channel 1 will be acquired at 50 kHz, channel 2 will be acquired with 20 kHz). Now this sample rate reduction can be done also for counter/digital channels which were so far always acquired with highest possible rate. Since this reduction will be done already on the device, a firmware upgrade is required to use this function.

Alias free filtering on Sirius HS

The Sirius HS slices are by default SAR type. This means that they have no filtering and the measurement will include also signals above Nyquist frequencies - a so called aliasing effect. With some measurements this is wanted, but usually the data should be clean from those signals. That is why we have introduced new AAF filtering. In this case Sirius will filter the data in analog, always acquire the data at high rate of 800 kHz and filter it and reduce it and filter in digital afterwards to the wanted sample rate. Be careful, this filtering is very demanding on the CPU so check your configuration uup front if a specific computer can handle the additional processing. In addition to that the user can also select in Settings - Advanced - Hardware that the alias free filtering is also switched on when manual IIR filters are selected.

Buffered mode for Krypton DI devices

Krypton digital input devices can now operate in buffered mode with speeds up to 40 kHz, fully synchronized with analog devices. With this feature digital data can be perfectly aligned with analog data.

Buffered mode for CAN devices on transmit in measure mode

CAN devices can receive data, but they can also transmit messages. Transmit can be used to operate a CAN based device to start, stop, operate a protocol like CCP or to transfer data from a measurement systems to another device. Data consistency can sometimes be the most important parameter. That means that the device on the other side requires data in regular time intervals. Buffered CAN transmit allows this since it will prepare the message queue up front with the data from input channels and transmit it in regular intervals. There will be of course some delay between the input and CAN output. This delay is defined manually and can be set from 200ms up to 5s.

New GiGE camera driver/new 600fps camera firmware a must-to-have upgrade

We have new camera firmware and the driver increasing the stability and performance of the camera. Is it a must-have upgrade for all DS CAM300 and DS CAM600 users.

NTP and GPS sync for Ethercat slices and Krypton

Krypton and Ethercat slices can be now synchronized with absolute time over NTP (accuracy <20ms) and GPS (<10us). This allows long term acquisition without time drift.

Safe mode for dual mode

Dewesoft solutions were always perceived as high end data acquisition solutions, but with technologies like dual mode (ability to send the data to control devices in parallel) they are used more and more as control/command frontends. With the increase in the usage of EtherCAT devices for data acquisition and control, we've made an improvement to the dual mode, called safe mode. It allows users to “lock” the EtherCAT data transmission with a password, so that it will continue without interruption in case of any software glitches. If DEWESoft needs to be restarted, the transmission will still continue until the user enters the chosen password.

Coming soon: Krypton devices available in simulation mode (SP3)

While not yet available in the current release, the much anticipated and highly requested support for offline Krypton amplifiers has been added to the development SP3 branch of DEWESoft X3. This allows users to fully configure their measurement even without connecting the actual hardware. This means you can create new setups or make adjustments to already existing ones in the comfort of your office, while the hardware can be used in ongoing measurements.

Applications

DEWESoft X3 adds several new features to different applications.

DYNAMIC SIGNAL ANALYSIS (DSA)

Order tracking (SP2):

3D graph y axis is now improved with lin, log, dB and sound dB scaling. This is especially useful in order tracking to show waterfall runup/coastdown frequency or order plots. Logarithmic scale can reveal low amplitude resonant frequencies.

Sound power (SP1):

Sound power is already available since some time to evaluate the amount of sound energy emitted from certain source like home appliance. We have added ISO 639 standard support making it even more universal and useful.

Reverberation time (SP1):

In Dewesoft X3 SP1 we added reverberation time measurement. The RT60 and alpha coefficient calculation is useful for building acoustics as well as for determining the characteristic of damping materials.

FFT (SP2):

The FFT analyzer is one of the most important features of DSA package, It is tuned with general improvements, channels are now set with automatic decimal places providing perfect visualization of data, Peak-to-peak amplitude type is added, when averaging is used, “stop after” function is added, FFT resolution can be defined in lines, delta frequency or block time duration. 2D graph got new FFT domain delta cursor.

Synthesized and true octave analysis (SP2):

Octave analysis is a-must-to-have tool for sound and vibration analysis. Dewesoft supports both: synthesized and true octave analysis. Synthesized analysis is calculated from frequency spectrum, it required low computing power and can be therefore used for fast evaluation. True octave spectrum is calculated like the old standard analog instruments were operated with a series of filters. It requires more computing power, but is a perfect match compared to standard SLM meters.
In recent Dewesoft X2 linear, peak and exponential averaging is added for octave analysis.

Envelope detection (SP2):

Envelope detection is very useful math function for bearing analysis. It filters the higher frequency band and creates envelope to detect outer ring, inner ring, balls or cage failures of the ball bearings. SKF standard bandwidths were added for easier setup (Envelope 1, 2, 3 and 4).

Acoustic weighting filters (SP1):

A new math module is added for calculation of acousting weighting: A, B, C, D. Input channel to the math can be analog signal where the output is time weighted signal. Input channel can be also spectrum where the output will be weighted spectrum.

Angle sensor math (SP1):

Angle sensor is a math module which extract frequency and angle out of analog sensor like tacho or geartooth with missing or double teeth. The module improved that the lower frequency limit can be set easier, and RPM/Hz unit for output frequency is implemented.

Orbit plot (SP3):

Orbit plot is used for oil bearing analysis where two displacement sensors are installed near the bearing. Orbit plot shows the movement of the shaft of turbine or generator inside this bearing. In the SP3 we have added the arrow to show the direction of harmonic movement. This is very useful for analysis of the behaviour of the rotor since the reverse direction can cause severe damage to the rotor and the bearing.

AUTOMOTIVE

Kistler KiRoad plugin

For road load data analysis Dewesoft is working since years with integrated acquisition of Kistler Roadyn2000. Kistler has made great improvements to the product line with new Kiroad device, implementing lossless TCP/IP protocol compared to UDP in Roadyn.

Dewesoft can now acquire the data from both devices. The most important is that the data from Kiroad and from other devices are acquired perfectly synchronized. For this purpose Dewesoft can use Kistler as clock master providing the clock to Dewesoft devices connected to the same system.

Pass by noise plugin upgrade

Pass by noise plugin was upgraded to work with latest hardware and Dewesoft X3.

Industry 4.0 Unilever Magnum digital

Did you notice that Magnum ice cream this summer tastes better than ever?
Believe it or not, Unilever has now optimized its production process using Dewesoft technology.

Mr. Luke Byrne (Process Manager, Unilever R&D Colworth, UK) and Mr. Roberto Sepe (Automation Engineer, Caivano Ice Cream factory, Italy) had a clear focus in their mind: the production process needed to be just perfect in order to guarantee the best taste, quality and stability of Magnum products, whilst minimizing waste…which is a winning combination!

It was clear since the beginning that these targets could be achieved only by introducing and embedding Industry 4.0 concepts in their manufacturing process and Dewesoft was the best partner to achieve that.

Byrne stated "This is great example of how R&D, supply chain, factory teams and key suppliers like Dewesoft can work together to deliver Industry 4.0 solutions that help deliver improvements in operability and line performance."

Our krypton extreme product line allowed us to distribute acquisition along the production process, integrating modules in existing electric cabinets, exactly where needed, in order to reduce analog signal cable length and improve the signal quality. It also reduced installation cost while ensuring perfect synchronization among all channels.

These units’ high protection grade (IP67) and wide temperature range (-40..+85°C) led them to be chosen by the experienced automation engineers from Unilever to be placed into these harsh environments.

Mr. Roberto Sepe felt that Unilever required a deep integration of the Dewesoft system with the already existing control systems.

We thank our developers who made possible a smooth integration with five different control systems for a total of 220 process parameters transferred using Siemens S7 native protocols, integrated with analog and digital values acquired by Dewesoft krypton frontends.

Acting as global supervisor, Dewesoft created a complete picture by gathering data coming from different parts of the production line and from various sources. Dewesoft tools then calculated complex algorithms in order to give useful indication to the operators and feed both the PLC control system set-points and the internal tools for statistics.

A red light alarm system instigates as soon as just a single parameter goes out of control within the production process. In such a case, the operators are advised to manually adjust valves if the control system cannot directly operate them.

This application offers proof that Dewesoft is not only a tool for acquisition and online analysis of data in industrial processes but also a comprehensive supervisor with a competitive price and fast implementation.

RT60 and alpha coefficient measurement

Introduction

Reverberation time is the time required for sound to decay 60 decibels from its initial level.

Reverberation time is measured in narrow bands and differs depending on the frequency band being measured. For precision, it is important to know what ranges of frequencies are being described by a reverberation time measurement.

Reverberation effects are often used in studios to add depth to sounds. Reverberation changes the perceived spectral structure of a sound, but does not alter the pitch.

Measurement setup

Let's say a customer is producing acoustic fillers for car interiors. The reverberation time is measured with and without the test specimen mounted in the alpha chamber.

The customer is using a DEWE-43 with MSI-BR-ACC adapter and a microphone. The reverberation time is calculated with the RT60 plugin and the absorption coefficient is calculated with the Excel template.

They are performing the measurement in the alpha chamber, which is a room with steel walls that fully reflect the sound.

In the picture below, there is a test specimen in the test chamber, two loudspeakers, and sound reflectors to disperse the sound in all directions.

Reverberation time measurement

The customer wants to calculate the reverberation time from 250Hz to 10000Hz. Because they cannot achieve a drop in the sound pressure level for more that 75dB, they are using the T20 evaluation range. For this evaluation range, only a 35 dB fall in each frequency band is required.

For the sound source, they are using a pink noise that is played on two loudspeakers placed inside the chamber. Pink noise is being played on the speaker, and after a couple of seconds the sound is turned off.

In the picture below, we can see how the sound pressure level falls. The blue curve is the sound pressure level in Decibels and the orange curve is the sound pressure from the microphone in Pascals.

The first cursor is locked at the beginning of the SPL fall, and the second cursor is placed at the position where the SPL level already reaches noise floor level.

The first measurement is an empty room measurement, where they acquire the reverberation time for an empty alpha chamber. The result is reverberation time T1 for each frequency band.

The second measurement is done with the test specimen inside the chamber. This test specimen is a foam that absorbs the sound in the doors of a car.

Alpha coefficient calculation

The Alpha Coefficient is a calculated using a formula in which both reverberation times are important parameters.

For calculation of alpha coefficient, they use an Excel templatethat stores all the formulas.

First, they enter the parameters about the room conditions and dimensions. The important parameter is the surface area of a test specimen.

Formula student noise measurement

Introduction

In order to pass the technical inspection for the formula student competition, all internal combustion engine cars need to pass a noise measurement procedure. In the unified rulebook it is stated:

IC3.3 Maximum Sound Level
At idle the maximum permitted sound level is 103 dBC, fast weighting. At all other speeds the maximum permitted sound level is 110 dBC, fast weighting.

IC3.2.1 The sound level will be measured during a static test. Measurements will be made with a free-field microphone placed free from obstructions at the exhaust outlet level, 0.5 m (19.68 inches) from the end of the exhaust outlet, at an angle of forty-five degrees (45°) with the outlet in the horizontal plane. The test will be run with the gearbox in neutral at the engine speed defined below. Where more than one exhaust outlet is present, the test will be repeated for each exhaust and the highest reading will be used.

IC3.2.4 Test Speeds
The maximum test speed for a given engine will be the engine speed that corresponds to an average piston speed of 914.4 m/min (3,000 ft. /min) for automotive or motorcycle engines, and 731.5 m/min (2,400 ft. /min) for "industrial engines". The calculated speed will be rounded to the nearest 500 rpm. The test speeds for typical engines will be published by the organizers.

The test was normally performed by one person using a hand-held sound level meter. Each team needed to have a dash display or a computer connected to show the engine RPM during the test.

Measurement setup

DEWESoft was one of the sponsors of the Formula student Austria 2017 competition at the Red Bull Ring in Spielberg, Germany. The event was also a promotion of the company and as such it was decided to do the noise test at a higher level.

Used Hardware

• Sirius ACC with high dynamic range
• GRAS microphone (for example GRAS 146AE)

Used Software

• Dewesoft X3
• Sound level meter plugin

Setup

It is stated in the rulebook that the maximum permitted sound level is 103dBC for fast weighting at idle and 110dBC for fast weighting at maximum RPM. Using the microphone with an ACC input in IEPE mode, the sound pressure in Pa is measured. By using the sound level meter and selecting only the correct frequency and time weighting, the sound pressure level output is created.

The measurement was made more interesting by detecting the engine RPM only by using the microphone. For this, the FFT analyser was used with peak amplitude output. Array function "maxpos" were used to get the exact frequency of the rotating engine. Then this was divided by the number of cylinders, multiplied by two and converted form Hz to RPM.

In some engines, other unwanted frequencies were present which made RPM detection more problematic. An IIR band pass filter solved this problem. Cut-off frequencies needed to be set below idle and above maximum RPM. Caution needs to be taken, since the frequency depends on the number of cylinders in the engine. In the competition only 4-stroke engines are allowed, which have one firing per cylinder every two engine revolutions. If a 4-cylinder engine is measured, there are 2 combustion cycles each engine revolution. This means that at 6000RPM, the frequency of the engine is 200Hz (6000*2/60).

There is also an input field in the setup for determining the engine test speed. In the rulebook, chapter IC3.2.4, it is stated that the maximum engine RPM for the test is calculated from the mean piston speed, which depends on the engine stroke.
The setup that was prepared is very simple for the operator. The number of engine cylinders need to be selected, engine stroke entered and then the measurement can start. There are two big indicators showing if the idle and maximum RPM noise levels are exceeded.

Conclusion

The DEWESoft noise test raised a lot of interest at the competition and teams were impressed with the capabilities of the hardware and software. Organisers from other events saw a video from the DEWESoft noise test at the competition in Austria and invited DEWESoft to do the same test at the formula student competition in Brazil.

The Formula student event is a good promotion for DEWESoft and a great chance for people to start working in automotive and other areas to get to know DEWESoft. Every team that passed the noise test received a printed report and an USB pen drive with the datafile, software and product catalogues.

Dewesoft was one of the sponsors of the Formula Student race at the Red Bull ring in Spielberg 2017. Dewesoft team performed noise tests on all competing formulas. In idle mode, their sound pressure level must not exceed 103 dB(C) and at maximum allowed RPMs, their sound pressure level must not exceed 110 dB(C). Only the teams that passed the test were allowed to compete in a endurance race. Each team received printed report and a Dewesoft USB stick with a datafile.

New PRO training courses

DEWESoft^® PRO training is a new learning platform that was created for current and aspiring-to-be measurement professionals.

NEW COURSES

We have released the following new PRO training course:

• Combustion analysis
  

  DEWESoft Combustion analysis math module enables the analysis of internal combustion engines. From measurements of pressure inside the cylinder and the angle of the shaft, we can calculate the main indication values for engine development and testing, like maximum pressure, position of maximum pressure, heat release, knocking and other important parameters.

  The combustion analyzer is fully integrated inside the DEWESoft software, which means that alongside it we can use any functionality of DEWESoft including CAN bus, video, other analog signal acquisition and more.

  The ProTraining will explain how to set up the combustion analyser in DEWESoft, how to do real measurement and how to use file replay to simulate pre-recorded analog signals. Example on how to use combustion analyser in combination with other modules, like torsional vibration (to convert the calculated torsional values to 0°-720° angle domain) is also explained. The chapter on ECU and Testbed communication describes how to send out combustion analysis data to other systems.
