Single Pulse Settings Specifies when the pulse is generated. You can choose to have the pulse always be generated when the step executes or only generated when the step executes and the specified trigger condition is met.
Continuous Pulse Settings Specifies whether the generated pulse is an Immediate Pulse or a Triggered Pulse. If you select Immediate Pulse, a pulse train starts when the step executes. If you select Triggered Pulse, a single pulse occurs every time the state of the selected trigger line has the specified polarity.
