The Simcenter SCADAS Mobile and SCADAS Recorder (formerly called LMS SCADAS) are part of a family of modular data acquisition devices used for capturing dynamic signals at a rate up to 204.8 kHz sampling rate per data channel.

 

The systems can read a variety of transducers, including strain gauges, accelerometers, microphones, thermocouples, speed encoders, GPS, digital CAN-bus, and more…

 The Simcenter SCADAS Mobile and Recorder are modular, and consist of a combination of:

  • Frame: Housing unit which contains all cards, controllers, and power supply. Comes in variety of sizes.
  • Master-Slave Module: Option used to combine or link multiple SCADAS frames together.
  • Power Supply: Contains battery for autonomous operation, also accepts external AC or DC power.
  • Mobile OR Recorder Controller Card:
    • The controller card is referred to as a XSI or Syscon card.  It is included with all SCADAS frames with the exception of slave frames.
    • Mobile: Ethernet interface for linking to control PC with Test.Lab software, two source outputs, two tachometer/encoder inputs.
    • Recorder: Same as Mobile with addition of Compact Flash for un-attended data acquisition, WiFi or Bluetooth for remote control, GPS/IRIG-B, and CAN-bus inputs.
  • Data Acquisition cards: Typically 8 or 24 input channels per card; see variety of card options in table below.

 

SCADAS is an acronym for Signal Conditioning and Data Acquisition System.

Frames:

Each SCADAS Mobile or SCADAS Recorder can be configured to customer-specific testing preferences:

  • SCADAS frames include either a SCADAS Mobile or SCADAS Recorder controller card, unless ordered as a slave frame. Any frame size can be ordered either as a Mobile or as a Recorder.
  • Empty slots are allowed. Expansion slots do not need to immediately be filled with a data acquisition card, since they can be installed later. Additions will be automatically recognized with no additional software configuration, etc.
  • Frames can be daisy-chained or linked through master-slave option (models 02-09 only).
  • For Vibration Control applications, the SCADAS can be ordered with a modified source.  The modified source has shutdown capability to avoid unintended test article and shaker system damage.

Cards: SCADAS_Card.png

 

Below is a list of cards available for the SCADAS frames.  Some key points:

  • Cards need to be placed in either an existing SCADAS frame or new SCADAS frame to function.
  • Cards typically consist of either 8 or 24 input channels.
  • Base codes in table below (e.g., VB8).  Cards when ordered will have extensions, for example "E" for Enhanced, or "-II" or "-III" for 2nd or 3rd generation (e.g., VB8-II).
  • Cards often have cable adaptors included.  For example, LEMO to BNC adaptors, etc.  Check with your sales representative to understand which cables are included when purchasing a specific card.
  • Some cards can have options for connector type, for example D-Shell connector instead of individual inputs.

One of the SCADAS at my work has vbiii, vc8e, and vd8e cards.

 

I did not see these listed in this article, but there are similar names like vb8, vc8, and vd8. Are these the same cards?

Siemens Phenom Siemens Phenom

Hi, those are the same cards!

 

In the article, the main name of the card is used, but there have been different models of each card over time, which is indicated by some extensions on the card name.

 

For example, extensions could include:

  • E - For Enhanced, which had a higher dynamic range than previous generation card
  • Roman Numerals - II, III, etc which indicate new models of the same card

Some more popular name variations:

 

V8:

  • V8-E

 

VD8:

  • VD-E

 

VS8:

  • VS8-E

 

V24:

  • V24-II

 

VB8:

  • VB8-II
  • VB8III-RT

 

VC8:

  • VC8-E
  • VC8-QS - Has suitable time constants for measuring pressure offsets like combustion

 

Hope that helps!

Mixing high sampling rate cards (V8, VB8, etc) with lower sample rate cards (V-24) in the same SCADAS Mobile frame? The V8/VB8 cards sample data at 204 kHz, the V-24 samples at 51 kHz.

 

 Wondering what sample rates are possible? Concerned that the sampling rates will be restricted to the lower rates?

 

Fear not, higher sample rates are possible.  Here is the breakdown:

  • Lower Rate - If data is acquired on channels from both the V-24 and the V8/VB8/etc than the highest possible sampling rate is 51 kHz.
  • Higher Rate – If data is only acquired on the channels of the higher sampling rate cards, then a sampling rate of 204 kHz is possible. The higher sample rate cards need to be the first cards in the frame.

 

Maximum Sampling Rate Scenario

 

Here are some of the particulars to ensure the maximum sampling rate:

1. First the V8 or VB8 cards should be the first cards in the frame.scadas_high.png2. In the Acquisition Setup worksheet of Signature, click on the “More…” button and set the ADC bandwidth to 102400.

 

acq_setup_max.png

 

 

Now the maximum sampling rate (204800 sampling rate is double the bandwidth) can be used.

 

Minimal Sampling Rate Scenario

 

Here are scenarios which would have the minimum sampling rate:

  • Channels active on both V-24 and V8/VB8 cards
  • Channels active only on V-24 cards

 

scadas_low.png

 

The ADC Bandwidth field is now maxed at 25600 Hz bandwidth (half the sampling rate of 51200 Hz).
