Description

MPIUserLimitOutputType represents the type of the user limit’s output block.

Member (MPIUserLimitOutputType...)	Associated Structure (MPIUserLimitConditionType...)	The user limit writes to...
NONE	none	The default output configuration. The user limit will not write any output.
SINGLE_SHOT	none	The user limit will only fire once. Upon triggering, the user limit disables itself.
MOTOR_GENERAL_OUT	MotorIo	Motor general-purpose digital outputs.
CONTROL_DIGITAL_IN	ControllerIo	The controller digital inputs.
CONTROL_DIGITAL_OUT	ControllerIo	The controller digital outputs.
SQNODE_DIGITAL_OUT	SqNodeDigitalIo	A SynqNet node’s digital outputs.
SQNODE_ANALOG_OUT	SqNodeAnalogIo	A SynqNet node’s analog outputs.
USER_BUFFER	UserBuffer	A user buffer location.
CUSTOM	Custom	A custom limit.

Sample Code

MPI_RESULT         returnValue; 
MPIUserLimit       userLimit;

    /* Use a single condition */

userEventConfig.trigger.type = MPIUserLimitTriggerTypeSINGLE_CONDITION;

userEventConfig.trigger.condition[0].data.axisActualPosition.logic      = MPIUserLimitLogicGT;

    /* Setup output block:  Set a SynqNet I/O Node's analog output. */

    /* Set node 3's analog channel 7 to a value of 1234             */
