Abstract
A regulating system can include a first controller configured to receive analog input and discrete input, a second controller communicatively coupled to the first controller, and configured to receive analog input and discrete input, a selector communicatively coupled to the first controller and second controller and configured to select either one of the first controller and the second controller as a master for the regulating system and state logic residing on each of the first controller and second controller to determine which of the first and second controller is the master.
Claims20
A regulating system, comprising:
- a first controller configured to receive analog input and discrete input;
- a second controller communicatively coupled to the first controller, and configured to receive analog input and discrete input;
- a selector communicatively coupled to the first controller and second controller and configured to select either one of the first controller and the second controller as a master for the regulating system;
- and
- state logic residing on each of the first controller and second controller to determine which of the first and second controller is the master.
A method for transferring state machine logic in a regulating system, the method comprising:
- in response to being a master of the system and having analog inputs, detecting an unhealthy status;
- communicating the unhealthy status to a backup controller and to a selector that switches the backup controller to a backup status and a master status;
- in response to being a backup of the system and receiving an unhealthy status from the backup controller, requesting to become a master of the system;
- and
- in response to being a backup of the system, identifying that the analog inputs agree with analog inputs for a master of the system, and identifying an out of boundary conditions of the analog inputs and the analog inputs of the master for the system, requesting to become master of the system.
A computer program product for transferring state machine logic in a regulating system, the computer program product including a non-transitory computer readable medium storing instructions for causing a computer to implement a method, the method comprising:
- in response to being a master of the system and having analog inputs, detecting an unhealthy status;
- communicating the unhealthy status to a backup controller and to a selector that switches the backup controller to a backup status and a master status;
- in response to being a backup of the system and receiving an unhealthy status from the backup controller, requesting to become a master of the system;
- and
- in response to being a backup of the system, identifying that the analog inputs agree with analog inputs for a master of the system, and identifying out of boundary conditions of the analog inputs and the analog inputs of the master for the system, requesting to become master of the system.
