Causes the diagram or subdiagram to wait a specified number of microseconds before completing execution.
Number of microseconds to wait.
Wiring a value of 0 to this input forces the current thread to yield control of the CPU.
Maximum Input Before Timer Wrap Around
Value of the operating system's microsecond timer after the wait.
The accuracy of the timer varies across operating systems. If the operating system takes more time to process a request than the time specified by the input, the actual wait time is longer than the time specified by the input.
If you need to ensure that an operation waits at least the specified time before completing execution, you can use either a Wait node or a Wait Until Next Multiple node. However, for functions that feedback an output as an input and require consistent timing between iterations to achieve equilibrium, such as a PID node in a loop, use a Wait Until Next Multiple node. Compared to Wait nodes, Wait Until Next Multiple nodes provide more periodic spacing between iterations because even if one iteration finishes late, the following iteration still executes on the multiple of the Wait Until Next Multiple input.
When an active execution system thread in a program reaches a Wait node in the millisecond configuration, the node execution is rescheduled cooperatively and the temporarily available thread can be used by other currently-executing code until the wait time expires.
When you use the microsecond or tick configuration of this node, the thread which encounters the Wait node is blocked until the wait time expires.
