1. An apparatus comprising:
- a hand held controller adapted to communicate with at least one item of process equipment, said controller communicating to an operator through a screen, said process equipment including multiple unit operations each having at least one parameter, said controller having an input for receiving the existing unit operations parameters, said controller graphically displaying multiple unit operations and the unit operations parameters so the operator can determine if the parameters are within an expected range, said controller enabling the user to navigate on screen between unit operations and to focus on any desired unit operation, said controller with an operator input modifying the parameters inside of the expected range, and said controller displaying the altered parameters on the screen so the operator can determine if they are within the expected range.

Abstract
A method and apparatus comprising a hand held controller adapted to communicate with at least one item of process equipment. The controller communicates to an operator through a screen using at least one graphical image. The operator uses the image to assess at least one operational parameter of the equipment. The operator may manipulate the controller to alter the parameter of the equipment.

10. A method comprising:
- providing a system characterized by process equipment including a plurality of unit operations each having at least one variable parameter, enabling the user through a hand-held computer-screen to see and navigate on screen between the unit operations and to focus on screen upon any desired unit operation, viewing at least one parameter in a graphical form, using said at least one parameter to assess a condition of said system, altering said at least one parameter of said condition, and communicating said alteration of said parameters back to said system.
