evaluated.
Notes
o
In this example, both dynamic measurements are started
simultaneously. They can also be started independently.
o
The time-triggered measurements are stopped in different ways:
measurement 1 is stopped after a certain time, measurement 2 is
stopped after a certain number of samples have been taken. Using
the time-triggered dynamic measurement, both methods are
equal.
In reality, one would use either of these methods for both
measurements.
o
The do-while-loop is finished, if all dynamic measurements are
finished. Since the first dynamic measurement stops earlier, it
would be possible to evaluate its measurement values earlier.
o
Measurement channel T2 is used in both dynamic measurements.
This is not a problem, since both dynamic measurements use an
independent recording of the measurement values.
8.10 Bit I/O
The exchange of Bit I/O data is similar to the static measurement.
The following figure shows the steps for the start of the Bit I/O data
exchange:
