Abstract

Methods and apparatus for coordinating operation of valves are disclosed. In some examples, an apparatus includes a valve controller to receive a first signal from a first control system to change an operating state of a valve, the valve controller is to provide the first control system exclusive control of the valve. In some examples, the valve controller is to receive a second signal from a second control system requesting permission to operate the valve, and send a response to the second control system indicating the first control system has exclusive control of the valve and has changed an operating state of the valve.
