compact DAQ timing

[JR3]

Hi,

We have been trying to install a data aquisition in our gasifier system.  We measure temperature(9211), pressure(9203), RPM speed (9205) and an analog output to control the blower (9263).  I have been trying to log the data per second but I'm always having errors after I put a DAQmx timing.  Could you help me out a bit. Everything is set on sample on demand except for the Mass feedrate which is at 1k samples 1kHz.  I'm really a beginner on these things.

Thanks

Hey Amado,

You will get error when you put DAQmx timing, as there is only one AI and one AO DAQmx timing engine, you cannot have two AI lines sampled at multiple rates. So try creating Global Virtual Channel with multiple tasks and try to run them at the same rate. and have a seperate task for AO.

Good luck 🙂
