A computer system for interoperable data exchange between a plurality of information systems via a digital representation service associated with a digital representation of a physical device with each information system being at least one of an information source and an information consumer regarding data associated with the physical device, the digital representation being a virtual entity replicating data of the physical device and data associated with the device life cycle, includes: at least one digital representation service for the physical device, the at least one digital representation service having: an interface for receiving a request for device related data; a management module for generating and updating the digital representation of the device, the digital representation storing a plurality of data models with each stored data model being associated with a particular information system; and a semantic relations library storing semantic relations between model element types from stored data models.

A production system, comprising circuitry configured to: collect synchronously collected data synchronized with a control period of a first industrial machine configured to control a second industrial machine; execute predetermined processing on all or a part of the synchronously collected data to acquire output data; and transmit the output data to an external device.

Exemplary embodiments pertain to a system that can include a high-level controller coupled to a low-level controller for controlling a physical asset. In one exemplary implementation, the high-level controller executes a first finite state machine for controlling a power generation unit via a network. The low-level controller executes a second finite state machine that may have fewer states than the first finite state machine. The second finite state machine places the low-level controller in a default mode of operation for controlling the power generation unit under various conditions such as when the high-level controller is controlling the physical asset during a normal mode of operation; when the high-level controller is revising the first finite state machine; when the high-level controller is controlling the physical asset using a revised first finite state machine; and/or upon detecting a loss of communications between the high-level controller and the low-level controller.
