An industrial automation system comprising:
- an emergency stop system configured to interrupt power to at least a portion of an industrial control system;
- and
- a user perceptible indicator associated with the emergency stop system that in use provides an indication to a user of an operative state of the emergency stop system.
An industrial automation emergency stop system comprising:
- an emergency stop circuit coupled to an emergency stop button, wherein the emergency stop circuit is configured to interrupt power to an automation device, a sensor, an automation controller, or any combination thereof when the emergency stop circuit is operative and the emergency stop button is actuated;
- wherein the emergency stop circuit includes state detection logic configured to determine whether the emergency stop button is in an operative state.
An industrial automation system comprising:
- a first operational zone;
- and
- an emergency stop system configured to be communicatively coupled to the first operational zone when the emergency stop system is within the first operational zone, wherein the emergency stop system is configured to interrupt power to at least a portion of the first operational zone when it is communicatively coupled to the first operational zone;
- and
- a user perceptible indicator associated with the emergency stop system that in use provides an indication to a user of an operative state of the emergency stop system.
