Abstract

A machine that has at least one actuated mechanism is remotely located from a control station. A two way real-time communication link connects the machine location with the control station. An interface at the control station allows an operator to select one or more virtual constraints on operation of the machine when the machine is performing a predetermined function. The virtual constraints are transmitted over the two way real-time communication link to the machine location. The machine has predetermined safety limits that are stored in a controlling device at the machine location. The stored predetermined safety limits are extracted and automatically mapped to the control station using the two way real-time communication link. The controlling device maps the predetermined safety limits to the virtual constraints.
