Abstract
A method is provided for saving the state of a real-time controller. The method includes receiving a command to save a state of a controller coupled to an industrial system, wherein the controller comprises a processor and a non-volatile memory, capturing the state of the controller during control and monitoring of the industrial system, and writing the captured state to the non-volatile memory of the controller.
Claims20
A method, comprising:
- receiving a command to save a state of a controller coupled to an industrial system, wherein the controller comprises a processor, and a non-volatile memory;
- capturing the state of the controller during control and monitoring of the industrial system;
- and
- writing the captured state to the non-volatile memory of the controller.
A system, comprising:
- a controller, comprising:
- a processor;
- a non-volatile memory coupled to the processor, wherein the non-volatile memory comprises instructions for:
- capturing the state of the controller, wherein the controller controls and monitors an industrial system coupled to the controller;
- and
- writing the captured state to the non-volatile memory of the controller, wherein the captured state comprises state variables and process variables of the controller.
A non-transitory tangible machine-readable medium comprising instructions for:
- providing a command to a controller to capture a state of the controller;
- copying the captured state from the controller to a workstation;
- loading the captured state in a simulation of a virtual controller, wherein the virtual controller emulates the controller;
- and
- executing the simulation of the virtual controller.
