Abstract:
Control apparatus having pre-defined error-states and related methods are described. An example non-transitory computer-readable medium disclosed herein comprises instructions that, when executed, cause a machine to analyze, via a controller coupled to a field device, a communication from a control system remotely located from the controller, the control system to operate the field control device during a non-error condition; detect an error condition while the field control device is communicatively coupled to and receives the communication from the control system; and override the communication between the control system and the controller to operate the field control device based on a pre-defined error-state instruction stored in the controller when the error condition is detected to cause the field control device to move to a first position for a first amount of time and subsequently move the field control device to a second position for a second amount of time, the first position being different than the second position.
