In a high speed application, I had to do a confirmity check on the first 8 to 10 mSec of a sensor "on" pulse which stretchs up to 16 to 17 mSec. My PLC scan time is 4 mSec. It is an inspection machine running 60 parts per sec. Desperately need some help, can a PLC do this or do I have to use some external high speed timers.
Thank you in advance.
