Overview

Description

The Delay block will delay the output of the input signal by the amount defined by the delay parameter. The units of the delay parameter are samples. The Delay block is useful when a Unit delay is required, often present in simulation models, or summation routines.

Example

This example shows you how to make a summation routine, where the model starts with 1 and after each sample, the output is added to the start value of one.

The configuration values for this block are as follows:

Delay	Delay. Out = in(t-delay) delay can be up to Maximum Delay samples.
Maximum Delay	Upper limit the Delay value in units of samples.
Evaluate Block	This block allows you to specify whether the block executes Every Sample, Every Other Sample (Odd or Even), or Every Fourth Sample (and specify the First, Second, Third, or Fourth). This provides greater flexibility in controlling the execution of a model and to preserve performance for other areas of motion control.
User Defined Block Priority	When selected, allows you to enter a Priority Code to modify Execution Ordering of this block. For more information, see Block Execution Order and User Defined Block Priority.
Priority	For an explanation of how the Priority field is used by the MechaWare Model Downloader, see Block Execution Order and User Defined Block Priority.
User Data 0	Application-specific data. See User Data Storage.
User Data 1	Application-specific data. See User Data Storage.

The Delay block will delay the output of the input signal by the amount defined by the delay parameter. The units of the delay parameter are samples. Out = in(t-delay) delay can be up to Maximum Delay samples.

The block has two user data fields (User Data 0, User Data 1) to store application-specific data for convenient storage and retrieval. See User Data Storage for details.

The block's update schedule is determined by the Evaluate Block. The following Parameter Dialog Box can be opened by double-clicking on the block in a Simulink Model:

Declaration

Public Method

	class DELAYBlock: public virtual Block { public: double Delay; };
	Required Header: mechaware.h

Description

The Delay block will delay the output of the input signal by the amount defined by the delay parameter. The units of the delay parameter are samples. Out = in(t-delay) delay can be up to Maximum Delay samples. The value of Maximum Delay cannot be configured through the C++ API. It is configured when the Simulink block is created.
