Hi All!
just want to check if i understand the manual correctly since the omron support has not answered me for 3 days now...
basically, i need to know the max frequency for the input modules as i need fast input pulses that vary from a few hundred hz to max of 5khz. these pulses will be used to calculate for flow rate and total volume.
based on the manual, the CJ1w-IDP01 has max ON input pulse of 0.05ms and max OFF pulse of 0.5ms which makes one pulse cycle=0.55ms or freq of approx 1818Hz(1/0.55ms)...is my assumption and calculation correct?
also, CJ1W-ID212 has default setting of 8ms on and off time but says can be set to 0-32ms on the cx-programmer...and 0ms setting means 15us ON response time and 90us OFF response time... which i assume to have total pulse cycle of 105us or freq of approx 9523hz(1/105us)?
can i use these modules for my application or do i need the fast counter module? total of 18 points needed for fast inputs
btw, im using CJ2m-CPU13 as controller.
hope the omron gurus can clarify this so i can purchase the correct modules and start programming already =)
best regards,
Paul S.
