Lag CANOpen controller and DAQ filters-CPU spikes

[mtamim]

I am writing this one here because my basic LabVIEW skills are entirely exhausted,

This VI's main job:

-Aquire two analog signals, apply same filters(single USB-6009)

-Timely send a CANOpen message populated from the different controls(PCI-8531)

Problem:

-Non periodic CPU spikes on the 32bit dual core remote PC running the executable(no labview, only up to date .NET, XP USB Hotfix, DAQMx and NI-VISA ) we have built here (on a 32-bit dual core), when the CPU spikes, the gauges freeze, Toggle switch LED slaves dont light until the 3-8 second lag is over, happens every 10-40 seconds,

Kindly (I stress kindly, I read what you guys do to the other noobs) let me in on where I went wrong,

Regards,

Hi mtamim,

start with the most prominent problem: there are a lot of loops in your code that run at unlimited speed - grabbing all the CPU power they can get.

Use some decent waits in those loops!

When you have done that:

- using a statemachine approach might be applicable to the big sequence structure!

- using TimedWhileLoops is probably overkill when you just call the DAQAssistent in there...
