Abstract

Systems and methods for a drilling rig. The method includes receiving, at a rig controller, data from a plurality of rig subsystems, and determining, at the rig controller, a first command based at least partially on the data from the plurality of rig subsystems. The first command is related to an operating parameter of a first device of a first one of the plurality of rig subsystems. The method also includes transmitting the first command to a first subsystem controller of the first one of the plurality of rig subsystems. The first subsystem controller is configured to control the first device and implement the command.
