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 |

hi, yes, this seems right. there is also an FAQ about this topic now: How do you calculate the cycle time of the analog input module AI 2xU/I 2-/4-wire HF of the ET 200SP depending on the parameterized interference frequency suppression and what influence does this have on a digital filtering via a smoothing factor?the most other analog input cards are working in the same way hope this helps, regards, |
