Select Configure Semaphore in the context menu for the step to launch the Semaphore Step Configuration dialog box from a TestStand User Interface . You can also click Configure Semaphore on the General tab of the Step Properties dialog box. In the Semaphore Step Configuration dialog box, select an operation for the step to perform.

The following operations are available when you use the Semaphore step type:

• Create —Creates a reference to a new or existing Semaphore object.
• Acquire (decrement) —You must perform this operation before you access a resource a semaphore protects.
• Release (increment) —Gives you direct control over the count. You can also use this operation to control semaphores in a way that requires unmatched increments and decrements.
  Note If you enable Auto Release in the Acquire operation, do not explicitly release the semaphore using the Release operation.
• Get Status —Obtains information about the current state of the semaphore.
