1. Login and Start Page
When first accessing the Simcenter SCADAS RS Recorder App via a browser, the user is usually prompted for a login and password. This can be found in the SCADAS RS manuals.
After logging in, the Simcenter SCADAS RS Recorder App main menu appears (Figure 2).
Figure 2: The main menu of the Simcenter SCADAS RS Recorder App.
From the main menu of the Simcenter SCADAS RS Recorder App, all functionalities can be accessed. Functionalities include setting up channels for data acquisition, defining triggers, recording data, and viewing already recorded measurements.
After entering a menu function, use the main menu icon (nine squares in the lower left) to return to the main menu. The back button in the upper left can also be used in the same way, although it may take multiple back operations to return.
If a Wi-Fi connection to the SCADAS RS is desired, but not yet enabled, click on the “Topology” icon. Find the REC unit, choose the “…” button and under “Wi-Fi settings” turn it on as shown in Figure 3.
Figure 3: The Simcenter SCADAS RS Wi-Fi settings via the Topology menu choice.
See the SCADAS RS manual for more information on the Internet Protocol (IP) address and wireless network name.
2. Channel Setup
Use the “Channels” icon from the main menu to configure the sensors and channels to be used in the data acquisition (Figure 4).
Figure 4: Use the “Channels” icon to setup measurement channels.
An overview of available modules in the SCADAS RS and their channels will be shown (Figure 5).
Figure 5: Use the double arrow icon (>>) in the upper right to collapse/expand the view of channels on available hardware acquisition modules.
The available channels are shown by hardware module. Available modules for the SCADAS RS include:
REC: Recorder module, the “brains” of the SCADAS RS. Hosts the Web App, 250 Gb of storage, GNSS/GPS, four CANbus inputs, and nine digital counters.
To view the available channels for a given SCADAS RS hardware module, use the separate single arrow shown in Figure 6.
Figure 6: Use the arrow on the left side to see available channels on a module.
Each row is one channel. Highlighting a channel brings up a “Channel Properties” menu on the right side of the screen (Figure 7).
Figure 7: Highlighting a row/channel opens a “Channel Properties” menu on the right side of the screen.
The “Channel Properties” menus contain key settings. They are organized groups:
Channel Conditioning: Voltage, ICP, Quarter Bridge, Half Bridge, Full Bridge.
Point Identity: Name the measurement in the Point field, for example “Left front suspension vertical”, “Control arm lateral”, or whatever will be used to identify the location of the measurement for later.
Transducer Factors: Set the engineering unit (strain, acceleration, displacement, etc) and enter the transducer sensitivity.
Bridge: Set the completion resistor, gauge factor. Only appears if one of the bridge options is selected in the “Channel Conditioning’ section.
When setting up the channel, the “Setup Channel” view is helpful. Click on the “…” to open the menu (Figure 8).
Figure 8: Click on the “…” to select “Setup channel” from the channel list.
The setup channel option shows some additional information (Figure 9):
Real-time Channel Levels
Real-time Time Signal
Real-time Frequency Spectrum
Figure 9: The “Setup Channel” option shows live signals, levels, and a wiring diagram for a given channel.
By showing the levels and signals in real-time, any problems in the channel setup can be changed and addressed quickly.
3. Multi-Channel Setup
When setting up the data acquisition channels, there are options to edit/change multiple channels at the same time. This can make channel setup faster, especially when dealing with hundreds of channels (Figure 10).
Figure 10: Multiple channels can be highlighted (in blue) using the control keys.
Multiple channels can be selected by clicking on them while holding down the CONTROL key. A range of channels can be selected by holding down SHIFT while selecting the first and last channel in a range.
In the “Channel Properties” any changes made will be applied to all channels.
Another useful feature is an indicator light for identifying where a module in the list is physically located (Figure 11).
Figure 11: The unit detection button causes a magenta light to blink on a module.
With a complex setup consisting of multiple units, the unite detection button causes a magenta light to blink on one module, making it easier to find.
4. Channel Calibration
Channels can be calibrated in the “Setup Channel” view.
An example of shunt calibration (using a SCADAS RS on-board shunt resistor) is shown in Figure 12.
Figure 12: Select “Shunt Calibration” on the left side of the “Channel Setup” screen.
Press the shunt calibration button on the left side of the “Setup Channel” screen. The name of the button is different depending on the type of transducer. A calibration screen is opened (Figure 13).
Figure 13: Press “Start” to perform the calibration.
In the calibration menu, press the “Start” button. The shunt calibration consists of zeroing the gauge, taking a reading, shunting, and taking another reading.
The newly calculated sensitivity is shown and can be used with the “Accept” button.
With all the channels setup and calibrated, measurements can be started as shown in Figure 14.
Figure 14: Use the “Measure” button on the left and select “Monitor” to get ready to measure.
To perform a measurement, press the “Measure” button on the left side of the screen and choose “Monitor”. The “Monitor” function can also be directly selected from the main menu.
The “Record” button starts the recording. In the upper right, the recording status and duration is shown (Figure 15).
Figure 15: The record button starts the measurement. The duration and status of the measurement are shown in the upper right.
There are several real-time views of the measurements that can be shown including statistics, digital readouts, strip chart, and levels. They are selected at the top center of the screen and can be switched actively.
Use the stop button to end the measurement.
6. Data Review
Once data has been acquired, any previous measurement can be reviewed (Figure 16).
Figure 16: Use the “View Data” button to get an overview of all available measurements.
Use the “View Data” button on the left side of the screen to get an overview of all measurements previously collected. The “View Data” is also available from the main menu.
To see the contents of an individual measurement, choose the magnifying glass icon to see it (Figure 17).
Figure 17: Contents of a measurement can be viewed in strip chart display.
Once a measurement is selected, the contents can be viewed as statistics or strip chart with the menu across the top center of the screen.
7. Using Mobile Devices
The Simcenter SCADAS RS Recorder App can be viewed from any device with a web browser.
PCs, tablets, and mobile phones all have different size screens. The Simcenter SCADAS RS Recorder App adjusts its appearance automatically based on the screen of the mobile device being used as shown in Figure 18.
Figure 18: Mobile versions of menus.
These adjustments are done automatically, without need for specific user intervention.
8. Triggers and Calculated Channels
Instead of manually pressing the record and stop buttons to take a measurement, it is possible to setup triggers to automatically start the measurement.
Trigger settings can be found in the “Recording Setup” screen under “Measure” as shown in Figure 19.
Figure 19: Triggers are defined under “Recording Setup” in Measure.
Both start and stop triggers may be defined. Specific levels on any channel can be set for the triggers as shown in Figure 20.
Figure 20: In this example, a trigger is defined on a measured string pot to start when 10 mm of displacement is achieved.
Triggers can have pretrigger buffers that record data leading up to the trigger.
In addition to levels on actual measured channels, triggers can also be used with calculated (or virtual channels).
Calculated channels are setup under the “Channels” menu, in “Calculated Channels” as shown in Figure 21.
Figure 21: Press the “Create +” button on the upper left to start making calculated channels.
Channel calculations include:
General: Math functions including SIN, SCALE, SQRT, SUM, etc
Conditioning: INTERPOLATE, LOOKUP, etc.
Logical: Produces values between 0 and 1 based on GREATER, SMALLER, AND, OR, etc
Trigonometric: COS, SIN, TAN, ATAN, etc
The calculated channels create additional time channels in addition to the measured channels.
The calculations can have multiple steps as shown in Figure 22.
Figure 22: In this case, the value of the calculated channel changes from 0 to 1 when both the string pot displacement exceed 10 mm and the strain gauge exceed 30 micro-strain.
In addition to measured channels, these calculated channels can be selected for the trigger.
