Portable computer in a process control environment
First Claim
1. A portable computer system for use in testing a process control system, comprising:
- a processing unit;
a computer readable memory;
a graphical display unit;
an input device adapted to produce an input signal;
a remote communication device that communicates with the process control system;
a first software routine run on the processing unit that requests plant level information from the process control system and displays the plant level information via the graphical display unit; and
a second software routine run on the processing unit that processes the input signal to develop a change signal indicating a change to be made in a process signal within the process control system and that communicates the change signal to the process control system via the remote communication device to thereby cause a change to be made to the process signal.

Abstract
A portable computer for use in interfacing to a process control system having a host system includes a housing adapted for hand-held operation, a processing unit disposed within the housing and a computer readable memory disposed within the housing and coupled to the processing unit. The portable computer also includes a display, a keypad and a radio frequency transceiver adapted to communicate with the host system, all of which are disposed within the housing and communicatively coupled to the processing unit. A first software routine stored in the computer readable memory processes a user input received from the keypad and sends a command to the host system via the radio frequency transceiver. Additionally, a second software routine stored in the computer readable memory receives process information sent from the host system in response to the command and displays the received process information via the portable computer display.
