Over the past several decades, rapid advances in semiconductors, automation, and control systems have resulted in the adoption of programmable logic controllers (PLCs) in an immense variety of environments. A synchronization system coordinates storage, retrieval, and activation of engineering object models among local and remote nodes. The synchronization system facilitates local and remote design and development access to the PLCs, as well as continued correct operation of the PLCs.

Data synchronization system for device based engineering

A system for configuration and control of a device includes a device processor includes at least two processing cores. Device firmware executes on a first processing core and a device-based engineering server executes on a second processing core. A web server running on the device-based engineering server includes a webApp providing web-based functionality for configuration and control of the device. The webApp is downloaded from the web server to the user's browser. A hypervisor manages communication between the device firmware and the device-based engineering server. A communication path established in the hypervisor for communicating a configuration or control instruction to the device firmware. The configuration or control instruction is initiated by a user via a web browser. The users web browser may run on a computer workstation that does not otherwise meet processing requirements of an engineering system for the device.
