First post.
We recently upgraded our machine from an SLC to compactlogix. In the SLC 5/05 we used analog 1746-ni8 cards for pressure and position sensors. When we moved over to the compactlogix 1769 l36erm with 1769-if16c cards we seen issues where the analog values had very little definition accuracy. This can be resolved by changing the filters but then the response time of the card is to slow and we miss data.
All of the relevant code from these sensors are in their own task and ive tried periodic, event and continous tasks but none of this helps.
The strange thing is with the SLC we never seen these issues.
Any ideas how i can improve the reponse time when the filters are set low?
