◆ HardwarePosLimitTriggerStateGet()

bool HardwarePosLimitTriggerStateGet ( )

Description:: HardwarePosLimitTriggerStateGet returns if the Hardware Positive Limit Trigger is Active High or Active Low.

Returns: (int32_t) 1 = triggers on active high signal, 0 = triggers on active low signal.

Sample Code:: Axis: Configuration
const bool ACTIVE_HIGH = true; // Constant for active high.

const bool ACTIVE_LOW = false; // Constant for active low.

const double HW_POS_DURATION_TIME = 0.01; // Positive limit duration. (in seconds)

const double HW_NEG_DURATION_TIME = 0.01; // Negative limit duration. (in seconds)

// SET (Hardware POSITIVE (+) Limit characteristics)

axis.HardwarePosLimitActionSet(RSIAction.RSIActionE_STOP); // Set the positive limit action to E_STOP.

axis.HardwarePosLimitTriggerStateSet(ACTIVE_HIGH); // Set the positive limit trigger state to ACTIVE_HIGH.

axis.HardwarePosLimitDurationSet(HW_POS_DURATION_TIME); // Set the positive limit duration to 0.01 seconds.

// GET

var hPosLimAct = axis.HardwarePosLimitActionGet();

var hPosLimTrigState = axis.HardwarePosLimitTriggerStateGet();

var hPosLimDur = axis.HardwarePosLimitDurationGet();

// SET (Hardware NEGATIVE (-) Limit charateristics)

axis.HardwareNegLimitActionSet(RSIAction.RSIActionE_STOP); // Set the negative limit action to E_STOP.

axis.HardwareNegLimitTriggerStateSet(ACTIVE_LOW); // Set the negative limit trigger state to ACTIVE_LOW.

axis.HardwareNegLimitDurationSet(HW_NEG_DURATION_TIME); // Set the negative limit duration to 0.01 seconds.

// GET

var hNegLimAct = axis.HardwareNegLimitActionGet();

var hNegLimTrigState = axis.HardwareNegLimitTriggerStateGet();

var hNegLimDur = axis.HardwareNegLimitDurationGet();

RapidSetup:: Go to axis screen->Limits & Actions. In the image below, HardwarePosLimitTriggerStateGet returns the trigger state shown in the Positive (+) Hardware box. It currently triggers on a HIGH because the "High" checkbox is checked.
