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

    bool ACTIVE_HIGH = true;
    bool ACTIVE_LOW = false;
    double HW_POS_DURATION_TIME = 0.01;  // Positive limit duration (in seconds)
    double HW_NEG_DURATION_TIME = 0.01;  // Negative limit duration (in seconds)
 
    // set pos & neg limits
    axis.HardwarePosLimitActionSet(RSIAction.RSIActionE_STOP);
    axis.HardwarePosLimitTriggerStateSet(ACTIVE_HIGH);
    axis.HardwarePosLimitDurationSet(HW_POS_DURATION_TIME);
 
    axis.HardwareNegLimitActionSet(RSIAction.RSIActionE_STOP);
    axis.HardwareNegLimitTriggerStateSet(ACTIVE_LOW);
    axis.HardwareNegLimitDurationSet(HW_NEG_DURATION_TIME);
 
    // get pos & neg limits
    RSIAction hPosLimAct = axis.HardwarePosLimitActionGet();
    bool hPosLimTrigState = axis.HardwarePosLimitTriggerStateGet();
    double hPosLimDur = axis.HardwarePosLimitDurationGet();
 
    RSIAction hNegLimAct = axis.HardwareNegLimitActionGet();
    bool hNegLimTrigState = axis.HardwareNegLimitTriggerStateGet();
    double 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.
