Pulser Module

The Pulser module serves as a intermediary between other module’s pulse output registers and a hardware output channel on the device. It converts the instantaneous pulses to pulses or transitions on a hardware output channel. With the module setup registers, you must specify whether the output is a transition or complete pulse, if it will pulse high or low, and the hardware port where the pulses will appear. For each pulse received at the Source input, a single pulse is sent to the specified hardware output channel.

Pulser Module Setup Registers

Setup Register	Description
Output Mode	Specifies whether the output is a complete pulse (PULSE) or a change of state
	transition (KYZ)
Pulse Width	Specifies the width (on-time) of the output pulse (e.g. how long an LED is lit or
	relay is open)
Polarity	Defines the output polarity of the pulses if you have selected a complete pulse as
	the Output Mode. It has no effect if you selected transition mode
Ports	Defines the hardware port where the output appears

Detailed Operation

Source input

Pulse from another module's Trigger or Pulse output register.

Characteristics of output pulse and destination port defined by setup registers.

Each second, the Pulser module determines how many pulses it has received on its Source input and outputs a like number of pulses to the specified hardware output channel. Because the PulseWidth setup register limits the output pulse to a minimum width, the Pulser module may not always be able to output a pulse for every pulse it receives on its Source input. In these cases, the extra pulses are sent to the hardware output channel in the next second. In cases where the Pulser module can output the correct number of pulses, these pulses are spread evenly throughout the second.
