Overview

Description

The Analog Output block is used to write analog values to outputs on Node I/O. The output is written at the update rate, which is specified by the Evaluate Block

Example

The following example illustrates a simple PID Control loop with a Clip to protect the motor from over current. Additionally, an analog input (another feedback source such as an Accelerometer) is sent into an AutoNull block and summed into the control loop.

Note the Node Analog Output is used to monitor the output of the AutoNull block. If this value is charted over time and the Analog Input varies, notice how quickly the output moves toward the Offset value and is determined by the Increment value specified in the AutoNull block.

The configuration values for this block arfe as follows:

Node Number	Node number for the input bit.
Channel	Defines which analog output channel to write to.
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 Node Number of the Analog Output specifies which SynqNet Node will be use for output.

The Channel defines which analog input channel on the node will be written to.

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

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:
