This article contains assorted tips on using Simcenter SCADAS RS
hardware with both the Simcenter SCADAS RS Recorder App
and Simcenter Testlab Neo
Tips include:1. Zero Before Acquisition
2. Custom Displays
3. Digital IO
4. Creating a Template
5. SCADAS RS Configuration Builder1. Zero Before Acquisition
When taking strain measurements, it is a common practice to “zero out” strain channels before starting a measurement.
It is possible to setup the SCADAS RS to automatically zero channels at the start of any acquisition. To set this up, click on "Recording Setup" from the main menu of the Simcenter SCADAS RS Recorder App as shown in Figure 1
Figure 1: From the main menu of the Simcenter SCADAS RS Recorder App, select "Recording Setup".
In the “Recording Setup” section, “Auto zeroing” can be turned ON as shown in Figure 2
Figure 2: Turning on “Auto zeroing” in the Recording Setup.
The measurement might contain several channels of non-strain data. So not all channels should be zeroed.
In this case, it is possible to exclude certain channels from being automatically zeroed. This is done in the “Offset Calibration” section of the software as shown in Figure 3.
Figure 3: In the “Zeroing” column, select which channels should be zeroed.
Using the “Zeroing” column, channels can be toggled on and off based on whether they should be zeroed or not.
2. Custom Displays
The Simcenter Testlab Recorder App has built-in strip chart and statistic displays that are active during acquisition. These built-in displays show all channels in a predesigned display. These displays are found in the “Monitor” section of the Recorder App.
However, custom displays can be created as well. This is done in the last tab of “Monitor” as shown in Figure 4:
Figure 4: In the “Custom” tab (right most tab in “Monitor”) users can create custom displays.
Gauge displays, XY displays, numerical displays are available in the custom display area.
3. Digital IO
On the main unit (REC unit) of the SCADAS RS, there is Digital Input and Output ports a shown in Figure 5.
Figure 5: A four channel digital input and output port is located on the SCADAS RS REC unit.
The digital output can be used to send out a voltage signal when levels are exceeded on a channel, at the end of an acquisition, etc.
In the “Recording Setup”, there is a tab called “Digital IO” where the outputs on the four different digital input output port pins can be defined as shown in Figure 6.
Figure 6: Setup menu for Digital IO port.
The Digital IO setup can evaluate many different conditions as shown in Figure 7.

The Digital IO feature can be used to trigger the shutdown of a test stand if vibration becomes too high, etc.
Templates are setup files that contain all the information needed to run a test. This includes channel information, trigger settings, and acquisition settings.
After setting up a test measurement, all the settings can be stored in a template. Templates are managed in the “Topology” and “Templates” icons of the main menu of the Simcenter Testlab Recorder App (Figure 8 below).
Figure 8: Both the “Topology” and “Template” icons are used to manage measurement templates.
To create a template of the current active measurement settings, click on the “Topology” icon.
In Topology area, click on “Save As” on the left side of the screen as shown in Figure 9.
Figure 9: Click on “Save As” to create a template with the current measurement settings.
After clicking “Save As”, fill in the template name and press the “Save” button. Press the back arrow (upper left) to go to the main menu.
To activate a saved template, from the main menu, click on the “Templates” icon. A list of all available templates should appear on the screen (Figure 10):

At the bottom of the template, press the “Load Template” icon to activate the settings.
5. SCADAS RS Configuration Builder
Want to setup a test template for the SCADAS RS, but don’t have the hardware?
Create a frontend configuration file (*.nfec) that can be used to set up a test without being connected to actual hardware using Simcenter Testlab Neo.
In the Windows search area, look for “scadas rs”. Start the “SCADAS RS Configuration Builder” as shown in Figure 11:
Figure 11: Search for “scadas rs” in Windows to start the “SCADAS RS Configuration Builder” utility.
In the SCADAS RS Configuration Builder, acquisition modules can be dragged from the library on the right to the measurement chains on the left as shown in Figure 12.
Figure 12: In the SCADAS RS Configuration Builder, move conditioning units from the library on the left to the measurement chain on the right.
A UPS and REC unit are already active by default.
Press the “Save” button (top row) after finalizing the hardware selection. The SCADAS RS hardware configuration will be stored in a *.nfec file. Exit the program after saving the file.
When starting Simcenter Testlab Neo acquisition, if selecting work offline mode, the *.nfec file can be selected as shown in Figure 13.
