An apparatus comprising:
- 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;
- 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.
A method comprising:
- receiving a first signal from a first control system at a valve controller to change an operating state of a valve, the valve controller is to provide the first control system exclusive control of the valve;
- receiving a second signal from a second control system at the valve controller requesting permission to operate the valve;
- and
- sending 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.
A non-transitory computer readable medium comprising instructions that, when executed, cause a valve controller to, at least:
