MONITORING CONTROL SYSTEM AND CONTROL DEVICE

摘要

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.

1. A monitoring control system comprising:
a control device that performs a device control process of controlling an operation of a device; and a high-order system that is connected to the control device and includes a monitoring terminal for monitoring the device control process, wherein 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, a data collection unit that 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, and an external transfer processing unit that transfers the device data stored in the built-in database to an external database provided in the high-order system if an external transfer condition is satisfied, and wherein the monitoring terminal acquires the device data from the external database or the built-in database by a search process.
