MotoHawk:Blocks:Data Write Block

Data Write

Current Version Help Data Write Help

This MotoHawkâ„¢ block writes a value to data defined by a MotoHawk Data Definition block.

Block ID

motohawk_data_write

Library

MotoHawk_lib/Data Storage Blocks

Description

Write value(s) to data defined by a MotoHawk Data Definition block. No type, bounds, or data structure checking is provided on the target. Such issues can be caught by simulation, with explicit warnings.

Block Parameters

Parameter Field	Values	Comments/Description
Data Source		Select method of obtaining source of data. An error is given if this does not match when the data source is by name. However, if the source is by input reference, the tool will not provide static error checking.
	Lookup by Name	Get data from source selected by name as entered in Data Definition block; if this option is selected the "Data Name" field is available for name entry.
	Input Reference Signal	Get data from explicitly provided dynamic reference signal.
	Lookup by Name in Structure	Get data from source selected by name of data and of structure as entered in Data Definition block (for Data Type "struct"); if this option is selected the "Data Name" field is available for name entry.
	Lookup by Name in Structure by Reference	Get data from explicitly provided dynamic reference signal in structure.
Data Structure		Select Structure of Data (must match that of Data Definition Block)
	Scalar	Single discrete value.
	Vector	Array of values (single row or column). Enables "Operation" selection field.
	Matrix	Table of Values (rows/columns). Enables "Operation" selection field.
Data Type	Drop-down list	Specify data type (must match that of Data Definition Block), or choose to obtain by reference.
Data Name	Alpha-numeric text, single-quote enclosed	Name of data source, if Lookup by Name is selected for Data Source. Must match exact name as defined in a Data Definition block. No special characters, such as spaces, dashes, commas (underscore allowed).
Allow writes to read-only data.	Check box (enable)	Check to enable writes to read-only data. The over-written data is not included in generated code.
Operation		Select method for obtaining structured data (field not available for "Scalar" selection in "Data Structure").
	Write scalar from location by index	Write single scalar, according to coordinate(s) index.
	Write entire data structure at once	Write entire vector or matrix; enables size fields per structure selected (Vector Size for Vector, or Numbers of Rows/Columns for Matrix).
Vector Size	Numeric	If Vector is selected, and entire data structure is to be written (per "Operation" selection), then set the vector size here.
Number of Rows	Numeric	If Matrix is selected, and entire data structure is to be read (per "Operation" selection), then set the number of rows of matrix here.
Number of Columns	Numeric	If Matrix is selected, and entire data structure is to be written (per "Operation" selection), then set the number of columns of matrix here.
Structure Instance Name	Alpha-numeric text, single-quote enclosed	Name of data source structure; field available if Lookup by Name in Structure is selected for Data Source. Must match exact name and structure as defined in a Data Definition block. No special characters, such as spaces, dashes, commas (underscore allowed).
No operation when null reference is input	Check box (enable)	Check to enable no operation when an input by reference option is selected, and the input reference is null.
