Hello LabVIEW Real-Time and DAQmx users,
National Instruments has recently released NI-DAQmx 7.4. Changes introduced in NI-DAQmx 7.4 provide increased flexibility when performing hardware-timed single-point operations on real-time platforms. The
Developer Zone Tutorial: DAQmx Hardware-Timed Single Point Lateness Checking has been created to help explain these changes. Information is also available in the NI-DAQmx Help.
In order to provide these changes in NI-DAQmx 7.4, the behavior of 'DAQmx Is Read or Write Late.vi', used in previous versions, had to be changed. In NI-DAQmx 7.4, the 'DAQmx Is Read or Write Late.vi' has been obsoleted and no longer performs any lateness checking. Applications being upgraded to NI-DAQmx 7.4 are recommended to use one of the lateness checking options discussed in the above tutorial.
Regards,
JR Andrews
