ICT Flexible control system based information and communication technologies

摘要

The present invention relates to an ICT-based flexible control system which can provide a control system capable of reflecting customer requirement by facilitating correction and maintenance of control logic and capable of promoting compatibility improvement by applying mutual communications between devices. The ICT-based flexible control system comprises: an input and output module combining means which includes a connector for attaching and detaching input and output modules for modification of control logic and optimization and expandability of hardware, obtains and changes data of the mounted input module into CAN communications data, outputs the CAN communications data to a main board, receives the control data outputted from the main board through CAN communications, and outputs the control data through the output module; and the main board which is connected to the input and output module combining means through CAN communications, changes the control logic in accordance with a hardware platform mounted by using CODESYS, which is standardized PLC software, and transfers the control data to the input and output module combining means through CAN communications.
