<p><P>PROBLEM TO BE SOLVED: To provide a plant monitoring control device and program, capable of performing an accurate reproduction test by grasping a relation between an external event that occurs and a process to be executed. <P>SOLUTION: The plant monitoring control device 1 is respectively connected to low-order controllers 5 for controlling a plant device 6 and devices related to control through a network to monitor and control the low-order controllers 5, detects the occurrence of an external event in a low-order control device 5 or a device and executes a predetermined process on the basis of the occurrence of the external event. Next, the plant monitoring control device refers to information of a process that is previously defined and started by the reception of the external event, and issues an event number for identifying the detected external event. Then, the plant monitoring control device associates a process execution history, which includes input data to be inputted to each process, process internal data before and after execution and output data being a process execution result, with the event number and with a process ID to record them. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
