Patent ID: 7869890

Claim:
A method of enabling an operator to control the operation of a process control plant, a control process in said process control plant being defined according to a plurality of control loops, said method being performed in a system, said method comprising: enabling operators to select a first key and a second key simultaneously, wherein said first key and said second key are respectively associated with a first control loop and a second control loop in said process control system, and are contained in a keyboard communicatively coupled to said system; and sending data to change a state of said first control loop in response to said simultaneous selection of said first key and a state of said second control loop in response to said simultaneous selection of said second key, wherein said first control loop and said second control loop are comprised in said plurality of control loops, and wherein ability to select said first key and said second key simultaneously enhances the speed with which operators can provide inputs in the management of said process control plant.
