Good evening,

I have some issues regarding update rate of an 6ES7 531-7KF00-0AB0 used for  motion control. According to the technical manual its possible to set the intergration time at:

-2,5 ms, 16,67 ms, 20 ms, 100ms.

But the only thing I can set in device view is the interference voltage suppresion and smoothing.

Although it seems that intererence frequency setting = 1 / integration time above?

Does anyone know how to set this integration / covnersion time now the update is approximately 100 ms.

Thanks in advance,
Daniel

Dear Denilson,

Thanks for your reply. Interference frequency does not have any relation with integration time. One is the surpressing frequency the other the time for data acquisitioin. 

But according to the manual of the card you can set the integration time but I can not find it in the hardware settings. The only thing that can be set is interference frequency.

Do you or anybody know if it is possible to set the integration time and if yes how.

Thanks in advance,

Daniel

Hello Daniel;

Since you seem to have already strong opinions on the subject, I will not try to convince you of anything.

But it is interesting, at least, to find that every setting of integration time (in ms) is the inverse of every available value of interference frequency in Hz... 2,5 ms inverted becomes 400Hz; 16,67 ms transforms to 60 Hz...

See the screeshot below, taken from this manual:

Analog input module AI 8xU/I/RTD/TC ST (6ES7531-7KF00-0AB0)

It's too bad that you have decided that it is impossible to set the one value by entering the inverse of the other that you can find in the parameter setup...

Hope this helps,

Daniel Chartier

Now, now Daniel, this isn't Facebook.

So you're saying, that to set the integration time, you ignore the "Smoothing" value and set the "Suppression" value as follows:

400 means integration time of 2.5ms
60 means integration time of 16.667ms
50 means integration time of 20ms
10 means integration time of 100ms

Is that what you're saying?
