Overview

The Memory Out User Buffer block is used to output a MechaWare block’s output to a user buffer register. Any of the controller’s user buffer registers can be written to by the Memory Out User Buffer block. Currently there are 1024 user buffer registers (defined by MFWUserDataSize).

Example

In the following example, the output of the summation routine is written to a User Buffer, which can be read by an application. This provides communication from MechaWare to your software.

The configuration values for this block are as follows:

Memory Out User Buffer Number	Memory Out User Buffer Number. Defines user buffer register that is written to by this block.
Data Type	Defines the data type of the data being written into the user buffer. Float (32 bits) Double (64 bits) Short integer (16 bits) Integer (32 bits) Long integer (64 bits)
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) or background. 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.

Matlab/Simulink

Simulink Interface

memout

The Memory Out User Buffer Number defines the register location that will be written to by this block. Data Type defines the type data type of the internal variable being written to by the block.

0 = float (32 bits)
1 = double (64 bits)
2 = short integer (16 bits)
3 = integer (32 bits)
4 = long integer (64 bits)

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:
