Adding Additional Settling Time

Setting the Settling Time

You can change the default settling time of a switch by using the niSwitch Property Node or the niSwitch_SetAttributeViReal64 function and NISWITCH_ATTR_SETTLING_TIME attribute.

In LabVIEW:

1. Add the niSwitch Property Node to the block diagram.
2. Click the property node and select Module Characteristics»Settling Time.
3. Right-click the Settling Time property and select Change to Write.
4. Right-click the Settling Time property and create a constant.
5. Set the constant to the amount of time (in seconds) to wait for settling.

In C:

1. Create a new ViSession named switchSession using the niswitchinit function.
2. Create a ViReal64 variable named settlingTime and set the value to the desired new settling time in seconds.
3. Call the function niSwitchCheckErr(niSwitch_SetAttributeViReal64(switchSession, VI_NULL, NISWITCH_ATTR_SETTLING_TIME, settlingTime));

Checking the Settling Time

You can check the default settling time of a switch by using the niSwitch Property Node or the niSwitch_CheckAttributeViReal64 function and NISWITCH_ATTR_SETTLING_TIME attribute.

In LabVIEW:

1. Add the niSwitch Property Node to the block diagram.
2. Click the property node and select Module Characteristics»Settling Time.
3. Right-click the Settling Time property and create an indicator.

In C:

1. Create a new ViSession named switchSession using the niswitchinit function.
2. Create a ViReal64 variable named settlingTime. Its value in seconds will be returned in the next step.
3. Call the function niSwitchCheckErr(niSwitch_GetAttributeViReal64(switchSession, VI_NULL, NISWITCH_ATTR_SETTLING_TIME, &settlingTime));
