Hi. I'v a Fox I/A AW70x running under Windows NT4.0
and I don't know why i have a very low cycle speed.
In other words when i move the MEAS parameter its take
about 63 seconds to update PNT parameter, ussing any
I/O block
If somebody knows why this is happening, please replay
to me as soon as possible. Thanks!!!!
We had a similar problem with I/A 6.1 on a Sun platform, so I don't know if
the solution will apply, but we found that having AIN blocks with filtering
turned on, but with the filter time set to 0.0 was causing a similar slowdown.
The answer was to either turn off filtering altogether (on a block by block
basis), or to give a non-zero filter time to blocks with filtering turned on.
Tim - I agree with the others on using an OSV of 10-15%. This is especially
true on level control loops.
