niSwitch Get Relay Name
Returns the relay name that is in the relay list at the specified index.
Use this VI in a For Loop to get a complete list of valid relay names for the switch module. Use the Number of Relays property to determine the number of relays.
 |
instrument handle identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize. | ||||||
 |
index is a 1-based index into the channel table. The default value is 1. The maximum value is equal to the value of the Channel Count property. | ||||||
 |
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. | ||||||
 |
relay name specifies the name of the relay. Examples of valid relay names: ch0, ab0, 1wire, hlselect For a list of valid relay names for the switch module, refer to Devices. |

 |
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.
