Returns the number of times the relay has changed from Closed to Open. Relay count is useful for tracking relay life and use.
Call the niSwitch Wait For Debounce node before this node to ensure an accurate count.
Control that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Name of the relay or set of relays to control.
You can supply a single relay name or comma-delimited list of relay names to control these relays. Examples of valid relay names are ch0, ab0, 1wire, and hlselect.
Indicator that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node and used for all subsequent NI-SWITCH calls.
Error information.
The node produces this output according to standard error behavior.
