Abstract
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.
