niSwitch Get Relay Count
Returns the number of times the relay has changed from Closed to Open. Relay count is useful for tracking relay lifetime and usage. Call niSwitch Wait for Debounce before this VI to ensure an accurate count.
Refer to Devices to determine if the switch module supports individual relay control.

instrument handle identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize. | ||||||

relay name specifies the name of the relay. Examples of valid relay names: ch0, ab0, 1wire, hlselect Refer to Devices for a list of valid relay names for the switch module.

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

instrument handle out identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize and used for all subsequent NI-SWITCH calls. | ||||||
 |
count is the number of relay cycles. | ||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
