20090212936 | APPARATUS AND METHOD FOR ALARM SUPPRESSION IN A MONITORING SYSTEM - A method, apparatus and system are provided that receive an alarm record and compare the alarm record to a suppression description that describes an alarm to be suppressed. A suppression flag of the received alarm record is set in accordance with a result of the comparison. A suppression trigger message may be received and compared to the suppression description. The suppression description may be enabled in accordance with the result of the suppression trigger message comparison and the alarm record compared to the suppression description only if the suppression description is enabled. | 08-27-2009 |
20130144404 | REAL TIME EVENT VIEWING ACROSS DISTRIBUTED CONTROL SYSTEM SERVERS - An automated event viewing method for a process control network that includes a plurality of distributed control system (DCS) servers that receive process event data from one or more industrial processes, wherein each DCS server is connected to one or more operator consoles for monitoring the one or more industrial processes. The method includes receiving process event data of the industrial processes in real time from the plurality of DCS servers and transmitting in real time the process event data of the industrial processes to one or more operator consoles that are not connected to the DCS server from which the process event data originated. | 06-06-2013 |

20130002697 | HISTORICAL ALARM ANALYSIS APPARATUS AND METHOD - A method includes partitioning alarms into two or more alarm groups. The alarms are associated with operation of an industrial process system performing a process, and each alarm has multiple states. The method also includes generating a graphical display for presentation to a user. The graphical display identifies at least one of the alarm groups and multiple alarm indicators. Each alarm indicator indicates a state transition of an associated alarm between two of the alarm's states. The alarm indicators are arranged in the graphical display based on times of their respective state transitions. | 01-03-2013 |

20150371418 | APPARATUS AND METHOD FOR VISUALIZATION OF OPTIMUM OPERATING ENVELOPE - A method includes identifying an envelope associated with a process variable in an industrial process control and automation system. The envelope is defined by an upper limit and a lower limit on the process variable. The method also includes generating a graphical display for presentation to an operator. The graphical display identifies a trend of a value of the process variable over time and the upper and lower limits of the envelope over time. The graphical display could also identify predicted upper and lower limits of the envelope a predicted target value of the process variable over a future time period. The graphical display could further identify when the value of the process variable falls outside the envelope. | 12-24-2015 |
