Abstract: A PLC, which is a control device includes a device memory that stores data acquired by an external sensor, a data extracting unit that periodically extracts data of predetermined types among the data stored in the device memory, a data distributing unit that stores the data extracted by the data extracting unit in an operation buffer corresponding to the data among a plurality of operation buffers provided according to the predetermined types, and a data tabulating unit that performs, when the operation buffer stores data equivalent to a predetermined period, arithmetic processing of the data stored in the operation buffer.

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 load distribution device includes: a combining unit to create a plurality of combinations for cases where each of a plurality of execution object programs is assigned to any one of a plurality of control devices; an estimating unit to estimate an all programs' completion time, which is a delay time taken from delivery of the plurality of execution object programs until return of execution results of the plurality of execution object programs to a delivery source, for each of the plurality of combinations created; and a selecting unit to select one combination whose all programs' completion time is shorter than a reference time, from the plurality of combinations created.

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.
