Abstract: The present invention provides a process monitorer, a process monitoring system, a process monitoring method, a process monitoring program, and a recording medium for monitoring processes in real time. The process monitorer including: a process information acquirer for acquiring process information indicating a state of a process provided from an industrial device; an indexed information generator for generating the indexed information indexed by a predetermined index based on the process information; a threshold acquirer for acquiring a threshold of the indexed information; a result of the determination generator for generating the result of the determination of the indexed information based on the threshold; a result of the determination notifier for notifying the result of the determination; an indexed information recorder for recording the indexed information; and a chart generator for generating a chart based on the indexed information.

Abstract: The present invention relates to an alarm management system for acquiring message data for alarms issued from a process and analyzing alarm behaviors. The alarm management system of the present invention selects unnecessary alarms from the message data for alarms and prevents alarms from being issued according to the results of alarm selection. Consequently, the system eliminates the need for engineers who have professional skills and experience, thereby making it possible to precisely select unnecessary alarms.

Abstract: A simulation section simulates an operation of a field device in the plant by using a device model. A comparing section compares actual output data of the field device with simulation output data that is obtained by simulation by the simulation section. A judging section judges occurrence of abnormality of the plant based on a comparison result by the comparing section. An error estimating section estimates an error between process data and input data, the process data being indicated as the input data to the field device, and the input data being actually inputted to the field device. In this case, the process data is corrected based on an estimation result by the error estimating section, and the corrected process data is inputted to the device model.
