How can i check the realtime ability of my program with LV 6.1?

[Alfred76]

Hi, i did use a PXI-6053E daq card with Labview RT 6.0.3, after upgrading to
LV 6.1 the single scan vi in my control loop displays no error, if i put too
much stuff in the loop. i check data remaining, everything exactly as in
the example i attached. With Labview 6.0.3 i did use the opcode "read
oldest" all the time and got a "1" at data remaining output if runnig too
slow. How can i check the realtime ability of my Program with LV 6.1? The
attached example is running with 35kHz and green RT-LED, even if i put a
"wait 1 ms" in the loop.
Thx4help.
Joerg

You should still be able to use the data remaining output of AI SingleScan to indicate that you are maintaining real-time as you did in LabVIEW 6.0.3. If this is not working properly for you, you might try wiping out the ni-rt folder on the RT system and re-installing the RT software on it through MAX on your host computer. Check the versions you have. If you are still seeing data remaining = 0 even when you are running your loop significantly slower than your scan rate, you might want to contact the LabVIEW RT group at National Instruments for additional assistance.
