Overview

Description

The Motor General Input block is used to read a single bit of data from the Motor General Input memory. This memory often contains state information for general Inputs/Outputs, and varies from device to device. The block is updated at the update rate, determined by the Evaluate Block.

Motor Number	The number of the motor from which to get the input. This number may be absolute or linked to the Model Number.
Bit Number	Bit to be used as input. Valid bit numbers are defined in MPIMotorGeneralIo.
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.

Arc Tangent Simulink Block

The Motor Number of the Motor General Input block specifies which Motor object will be used for input.

The Bit Number defines which bit should be used for the input. Bit 0 is always the LSB for the input. The MSB is 31.

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:

Declaration

Public Method

	class MOTOR_GENERAL_INPUTBlock: public virtual Block { public: // User accessible coefficients long BitNumber; };
	Required Header: mechaware.h

Description

The Motor Dedicated Input block is a special case of the Bit Input block. Used as a convenient way of targeting the motor’s input bits, abstracting the need for a source address and data type. See Overview for more information.
