How fast can output be set on a Picolog 1216?

Postby kstoffer » Fri Sep 13, 2013 9:13 am

I have been playing around with setting the digital output on the picolog 1216 device using the pl1000.dll api interface (pl1000SetDo command) it takes about 16 ms for the function to return which for my application is way to slow - is this the expected behavior - is there a way to set outputs faster? The same is true for the pulsewidth modulation output. Other functions return much quicker (eg.: pl1000MaxValue) in about 0.002 ms so it is not overhead in calling the dll.

HI Kristoffer,

This is the expected behaviour of the driver. For historical reasons, there may be an enforced delay to allow settling of the outputs following a live write. Please note that there is an overhead on the USB write which will be PC/OS dependant.

I hope this helps.
