Description
MPIUserLimitConditionAxisPosition represents an axis position condition’s data for a user limit’s trigger.
| axisNumber | The axis number whose position is used for the trigger condition. |
|---|---|
| position | The position value to which the position will be compared. |
| logic | The logic used to compare the position to the position member. If logic is MPIUserLimitLogicGT, then the condition will evaluate true when the axis’ position is greater than the position member. |
Sample Code
MPI_RESULT returnValue; MPIUserLimit userLimit; MPIUserLimitConfig userEventConfig; /* ... */ returnValue = mpiUserLimitConfigDefault(&userEventConfig); msgCHECK(returnValue); /* Generate an event */ userEventConfig.generateEvent = TRUE; /* Use a single condition */ userEventConfig.trigger.type = MPIUserLimitTriggerTypeSINGLE_CONDITION; /* Trigger when axis 5's actual position exceeds 300000 */ userEventConfig.trigger.condition[0].type = MPIUserLimitConditionTypeAXIS_ACTUAL_POSITION; userEventConfig.trigger.condition[0].data.axisActualPosition.axisNumber = 5; userEventConfig.trigger.condition[0].data.axisActualPosition.position = 300000; 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 */ userEventConfig.output.type = MPIUserLimitOutputTypeSQNODE_ANALOG_OUT; userEventConfig.output.data.sqNodeAnalogOut.nodeNumber = 3; userEventConfig.output.data.sqNodeAnalogOut.channel = 7; userEventConfig.output.data.sqNodeAnalogOut.newValue.i16 = 1234; returnValue = mpiUserLimitConfigSet(userLimit, &userEventConfig); msgCHECK(returnValue);
