henriks Posted March 22, 2015 Report Posted March 22, 2015 Greetings! I just have one question. Is it possible to get pulse time down to 5ms? I have only been using down to 10ms so far. Im using the M8011 timer memory. Thanks in advance! Best Regards Henrik. Quote
JRoss Posted March 23, 2015 Report Posted March 23, 2015 Which PLC model? The short answer is no, 10ms is the limit for pulses. Even if you could, you would have a problem with scan time. If the scan time of your program is longer than the pulse cycle, you could easily miss a pulse. 5ms is on the low end. What are you trying to do? Is it something you could use a 1ms timer for instead? Quote
henriks Posted March 23, 2015 Author Report Posted March 23, 2015 Thanks for the answer. Will look closer on the 1ms timer. I'm using the FX3U and working with 110 valves. Point is to make a "picture" in the "waterfall", so in need for quick pulsing to the valves. Quote
Inntele Posted March 23, 2015 Report Posted March 23, 2015 I'd recommend you to look at M8099/D8099 0,1ms high-speed ring counter and to REF instruction. Quote
