US Patent:

6690980, Feb 10, 2004

Filed:

Sep 13, 2001

Appl. No.:

09/950974

Inventors:

Terry Wayne Powell - Johnson City TN

Assignee:

Siemens Energy Automation - Alpharetta GA

International Classification:

G06F 1900

US Classification:

700 80, 700 21, 700109

Abstract:

An alarm event generation method and apparatus for signaling an alarm ( ) for a process control system ( ). The process control system ( ) monitors a production run using a computer system ( ). The computer system ( ) collects process data corresponding to the production run from operator workstations ( ) and stores the process data in a process data database ( ). The process data includes a plurality of process parameter counts ( ) each corresponding to a process parameter type ( ). The process parameter counts ( ) are polled from the computer system ( ). Each process parameter count ( ) has a corresponding manufacturing limit ( ) to which it is compared. When a polled process parameter count ( ) exceeds its corresponding manufacturing limit ( ), an alarm ( ) is signaled. While an alarm ( ) is being signaled, the computer system ( ) is prevented from collecting and storing process data.

International Classification:

G05B 902

US Classification:

700 80

Abstract:

An alarm event generation method and apparatus for signaling an alarm (436, 1400) for a process control system (100). The process control system (100) monitors a production run using a computer system (108). The computer system (108) collects process data corresponding to the production run from operator workstations (104, 106) and stores the process data in a process data database (110). The process data includes a plurality of process parameter counts (430) each corresponding to a process parameter type (428). The process parameter counts (430) are polled from the computer system (108). Each process parameter count (430) has a corresponding manufacturing limit (434) to which it is compared. When a polled process parameter count (430) exceeds its corresponding manufacturing limit (434), an alarm (436, 1400) is signaled. While an alarm (436, 1400) is being signaled, the computer system (108) is prevented from collecting and storing process data.
