Description
Measure blocks are used to create a sampling schedule for sensor blocks. The only time a
Measure block (or similar) is not needed after a sensor block is when the sensor block is set to
output data based on a specified change on the sensor input (Event mode).
Enter values for the Time and the Interval. The interval is how often the data from the sensor
should be sampled. The time is a synchronization time (not an start time). In the example below,
the sensor will be sampled every fifteen minutes, synchronized to the hour. If
Time had been set
to 00:01:00, the sensor would be sampled every fifteen minutes with a one minute offset – if
sampling was started at 4:00pm, samples would be taken at 4:16p, 4:31p, 4:46p, etc.
Sensor blocks configured in Event mode do not need to be hooked-up to Measure blocks, but
they can be if desired. Doing so will result in data being generated
either because of a specified
change in the sensor input or because the next scheduled sampling time has arrived.
