Computed Channels; Computed Channel Generic Parameters - HBM SomatXR CX23-R User Manual

Viewing camera channels in Somat InField
To be able to view camera data in InField, it is necessary to create a channel with time information and add it to a
history. Make sure that the Time History sample rate is higher than the camera frame rate.
To view the recorded data:
1. Start InField and open the SIE file with the camera message data.
2. In the channels list, highlight the camera message channel and the time history channel and click the multiplot button.
3. In the resulting multiplot, use the cursor to scroll through the data. The image shows the camera frame at the time
value of the cursor.
Consider the following when viewing camera data in InField:
If a second cursor is enabled, the images from the camera channel are still tracked to the first cursor. Return to single
cursor mode to continue scrolling through the camera frames.
The timestamp of the image is indicated by the x -value on the multiplot. The timestamp is test run time. To calculate
the real time, view the test start time in the metadata viewer and add the x -value in seconds.
It is possible for the test not to record the full requested frame rate due to camera functionality. If the load on the
network or the data processor unit is high, the camera my drop frames to avoid a lag in the data stream.
When scrolling through the high sample rate time history channel, the camera image repeats itself for every sample of
time history data until the next camera frame in the data stream.
CX23-R and EX23-R
CAUTION
Video streaming is both CPU intensive and data intensive when using multiple
cameras. Long tests can easily fill the unit's hard drive or a large number of
channels can overload the CPU such that a test is not able to start. If either of
these issues occur, reduce the image quality parameters of the camera
channels.
4.4 Computed channels
4.4.1 Computed channel generic parameters
Name: Enter a name for the channel. The name must be unique and contain valid
characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<' and
'>'). Invalid channel names are 'true' and 'false' (case sensitive).
Collect: Select the Collect checkbox to write the channel data to the SIE data file
during a test run.
Enable notifications: Select the checkbox so notifications (through email or the
HBM Push application) may be sent for the Over range detector Computed
channel. See Notifications
sent from the system.
Description: Enter an optional detailed description of the computed channel.
Input channel with sample rate: Set the desired input channel. In the edit
dialog, the channel sample rate is displayed in S/s.
Measurand: Enter the quantity being measured or the type of measurement
associated with the computed channel.
