Generates the point-by-point value of a step signal.

connector_pane_image
datatype_icon

reset

A Boolean that specifies the initialization of the internal state of the node.

True Initializes the internal state of the node by returning the output at time t = 0.
False Does not initialize the internal state of the node.

Default: False

datatype_icon

amplitude

Amplitude of the step signal.

Default: 1

datatype_icon

offset

Lower limit of the step signal.

Default: 0

datatype_icon

step time

Simulation time, in seconds, at which the output changes from offset to offset + amplitude.

Default: 0

datatype_icon

dt

Loop-cycle time or interval, in seconds, at which this node is called.

dt must be greater than zero.

datatype_icon

step output

Point-by-point value of the step signal.

Algorithm Definition for the Step Signal

The following equations define the step signal:

y = { u ⁢               if ⁢   t < step ⁢     time u + a ⁢           if ⁢   t ≥ step ⁢   time

where

  • y is the step signal
  • u is the lower limit of the step signal
  • a is the amplitude of the step signal
  • t is the current simulation time

Where This Node Can Run:

Desktop OS: Windows

FPGA: This product does not support FPGA devices

Web Server: Not supported in VIs that run in a web application
