	typedef struct MPIMotorEventConfig { MPIAction action; MPIMotorEventTrigger trigger; MPI_BOOL direction; float duration; /* seconds */ } MPIMotorEventConfig;
	Change History: Modified in the 03.03.00

Description

MPIMotorEventConfig is a structure used to configure Motor Events.

action	The action to be taken on the associated axis when the event is triggered (when the event status changes from FALSE to TRUE).
trigger	The trigger configuration for an event.
direction	Only used for Hardware and Software limits. Setting *direction* to TRUE requires the direction of motion to be in direction of the Limit to trigger the event. If *direction* is set to FALSE, a limit event can be generated regardless of the direction of motion.
duration	time that Limit (e.g. Home, Pos. and Neg. Limits, User Limit) must be asserted before Event is generated. Value in seconds. NOTE: The duration parameter for the home limit should be zero for standard configurations. A non-zero value will result in the home limit being missed.

Description

MEIMotorEventConfig is an enumeration of encoder feedback inputs for a motor.

condition	is a structure that configures the conditional statements evaluated to generate a Limit Event. Each limit may have up to two conditions (MEIXmpLimitConditions = 2). This structure is described in further detail on the User Limits page.
status	an enum that defines what actions the XMP will take when a user limit evaluates TRUE. Always set Status to at least MEIXmpStatusLIMIT to notify the motor object that a limit has occurred. Valid Status values are listed in the Values of Status table below.
logic	an enum that sets the logic applied between the two condition block outputs, Condition[0] and Condition[1]. Valid Logic values are listed in the Values of Logic table below.
output	is a structure that allows specific action to be taken when the Limit Event is generated. In addition to generating a Motion Action, a Limit can write to any other valid XMP Firmware register defined in the *OutputPtr with value described by AndMask and OrMask. This structure is described in further detail on the User Limits page.
count	For internal use only. The MPI method, mpiMotorEventConfigSet(...) will not write these values.
state	For internal use only. The MPI method, mpiMotorEventConfigSet(...) will not write these values.

Values of Status	Action to be taken
MEIXmpStatusLIMIT	None
MEIXmpStatusLIMIT \| MEIXmpStatusPAUSE	Axes attached to the motor will be Paused
MEIXmpStatusLIMIT \| MEIXmpStatusSTOP	Axes attached to the motor will be Stopped
MEIXmpStatusLIMIT \| MEIXmpStatusABORT	Axes attached to the motor will be Aborted
MEIXmpStatusLIMIT \| MEIXmpStatusESTOP	Axes attached to the motor will be E-Stopped
MEIXmpStatusLIMIT \| MEIXmpStatusESTOP_ABORT	Axes attached to the motor will be E-Stopped and Aborted

Values of Logic	Evaluates	Motor object notified that a limit has occurred if...
MEIXmpLogicNEVER	Nothing	No event is generated
MEIXmpLogicSINGLE	Condition[0]	Condition[0] = = TRUE
MEIXmpLogicOR	Condition[0], Condition[1]	(Condition[0] \|\| Condition[1]) = = TRUE
MEIXmpLogicAND	Condition[0], Condition[1]	(Condition[0] && Condition[1]) = = TRUE
other MEIXmpLogic enums	For internal use only.
