Setting Property at design time and run time differ outputs

[Developer 162]

On AI OCX Object I have set property in BUFFER>>Number of Scan to acquire = 600, Allocation Mode = Host Memory, Return data type = scaled data only And in Clock >> Clock=Scan, Clock Sourec Type = Internal,Scan/Second = 600 And in CONDITIONS>> Condition=Stop and Continuous..

But when I want to set them at runtime I am not getting proper output


I have defined at runtime...
CWAI1.NScans = 600
CWAI1.ScanClock.Frequency = 600
CWAI1.AllocationMode = cwaiHostMemory
CWAI1.ScanClock.InternalClockMode = cwaiFrequency
CWAI1.ScanClock.ClockSourceType = cwaiInternalCS
CWAI1.UseDefaultBufferSize = True
CWAI1.Configure CWAI1.start


Please guide me ... where I am gettin
g wrong

Hmmm, it looks like everything you have is correct. Except that it appears you haven't specified the channels you want to acquire from. I would expect to see something like this:

CWAI1.Channels.RemoveAll
CWAI1.Channels.Add "1,2,3"

I have attached one of the shipping examples that also programatically specifies the properties. You might use it as a comparison to your code. I hope this helps.

Thanx Russel for your suggestion!

Actually I have not written this in question beacuse without this how can I get data...

These lines are written before my code..

CWAI1.Channels.RemoveAll
CWAI1.Channels.Add Channel_name

I dont understand the problem, Graph plotted is very when we directley specify in OCX properties... rather then at run time..

Does the attachment have the same problem as your code? If so, then perhaps you could tell me a little more about what the data does look like verses what it is supposed to look like. Exactly, what is different about it? Maybe some screen shots would help too?
