Communication system and method for a barrier operator

Abstract:

A system and method for communicating with a barrier operator system to direct operation of a barrier. The system and method may include adaptively updating an expected time duration for an operational sequence that includes occurrence of an event relating to operation of the barrier operator system and receipt of a status message from the barrier operator system. The system may monitor and record the elapsed time for the operational sequence, and determine the expected time duration for the operational sequence based on the recorded history of elapsed times. If the status message is not received within the expected time duration after occurrence of the event, the system may transmit a status request message to the barrier operator system to obtain information relating to the status of the barrier operator system or the barrier, or both.
