FP-2000

[grisel]

I need to do some polling on a FP DI 301 using a FP2000 to catch pulse and the precise time associated with each pulse (1msec accuracy). I ave used FP read and FP advise but with a very poor precision(best 1 msec and very often 10 msec). Is it normal or due to the way I have written my soft?Thanks for answer.

This is normal timing for a FieldPoint. The FP-DI-301 has a 1 ms propogation delay time from when the signal changes to when the network module sees the change. Performance tests of the FP-2000 have shown a maximum read rate (consecutively reading a single module at the maximum rate, including tweaking software priority levels) of 800 Hz.

There are a number of ways to tweak performance. One parameter that you can change is the "Pause" time. You can change the pause time from 0 ms to 1000 ms in 1 ms increments by right-clicking on the FP-20xx in FieldPoint Explorer and choosing Edit this Device.
The Pause time is the amount of time that the FieldPoint Control Environment goes to sleep. The FieldPoint Control Environment publishes the I/O module data to the ne
twork but is not directly used by an embedded program.
