Abstract: A monitoring control device includes a plug-in management unit that dynamically loads a plug-in made up of a plurality of actions, and that calls a predefined common function, declared in a program of the plug-in, in order to control the execution of an action stored in the plug-in, and extend a function of the monitoring control system, and an action-parameter management unit that holds arrays, in each of which an action parameter is stored, that is a parameter needed for an individual action included in the plug-in, by the number of actions described in a job file, and that designates an identifier and an element index of the arrays in order to read or write a value of the action parameter.

Abstract: A monitoring control system includes a control device that performs a device control process, and a high-order system that monitors the device control process. The control device includes a control CPU that performs the device control process, and an information CPU that is connected to the control CPU via an internal bus. The control CPU includes a device memory that stores therein device data to be used for the device control process, the device data being related to the device. The information CPU includes a built-in database and a data collection unit. The data collection unit performs a data collection process of reading the device data from the device memory via the internal bus, and storing the read device data in the built-in database.
