Abstract
A human-machine-interface (HMI) system comprises a machine interface, a communication interface, and a processing system. The machine interface receives operation data from a plurality of machines within an industrial automation environment, wherein the operation data corresponds to operations of the plurality of machines. The communication interface receives a request for a remote viewing session from a communication device, and in response to the request, transfers graphics data and the operation data for delivery to and display by the communication device. The processing system monitors for changes to the graphics data and the operation data during the remote viewing session. The communication, upon a change occurring to the graphics data, transfers updated graphics data for delivery to and display by the communication device, and upon a change occurring to the operation data, transfers updated operation data for delivery to and display by the communication device.
