ABSTRACT:
Graphically intense utility programs for an industrial control system, requiring the same operating system as is used to run the control program, are run on remote computers having insufficient memory or processing power to support the operating system, by using a shell program executing on a control-computer to run the utilities. The shell program uses the control-computer's operating system except for calls to the remote computer's display or its manual input devices which are routed to a virtual machine updated periodically by communication with the remote machine.
