I-O Display Systems Basic I/O Product Introduction, Digital inputs, Read, Pulse widths, One Shot

	Introduction 1
	Digital inputs
Read	Read the on or off of all inputs
Pulse widths	The duration of a single or total on/off time of consecutive
	pulses can be resolved to the nearest 0.00 seconds for a max
	total of 10.9 minutes, or 46.6 hours with multiplied resolution.
	Positive or negative edges initiate measurements. The time
	scale can be multiplied by a factor of 1-256 on a system wide
	basis.
Pulse counting	Pulses can be counted up to a total or 65,535. To be reliably
	counted, pulses must have minimum on and off times of 1
	mSec. Thus the maximum counting rate for a 50% duty cycle
	squarewave with equal on and off times for a total of 2 mSec.
	Would be 500Hz.
Edge detection	Off to on and on to off transitions can be detected within 1
	mSec. Of their occurrence. Action is only reported every
	10mSec.

Note: The response time performance of digital input instructions can be limited by the delay in the input modules themselves which can nave on plus off delays of up to 40 mSec.

	Digital outputs
Set Outputs	Can set individual or multiple outputs on or off Modifiers
One Shot	Can generate on or off pulse durations of up to 655.35 seconds
	with a resolution of 0.01 seconds. Resolution can be further
	multiplied by a factor of 1-256on a system wide basis.
Delayed	Can generate on or off pulse durations of up to 655.35 seconds
	with a resolution of 0.01 seconds. Resolution can be further
	multiplied by a factor of 1-256on a system wide basis.
