2023-09-14, 10:50–11:10 (Asia/Tokyo), Terrsa Hall B

In the manufacturing industry, the trend toward digitalization is progressing rapidly. As a result, information and manufacturing systems are being integrated to realize Industry 4.0 and DX(Digital Transformation). However, in the midst of this trend, damage caused by cyber-attacks has become more apparent, and cyber-attacks are on the rise. As a result, there is an increasing need for cybersecurity measures and education in the manufacturing industry and factories.The Purdue model used for modeling industrial control systems represents the system hierarchically as follows:
1. ERP (Enterprise Resource Program): Management level [L4]
2. MES (Manufacturing Execution System): Planning level [L3]
3. SCADA (Supervisory Control and Data Acquisition): Supervisory level [L2]
4. PLC (Programmable Logic Controller)/DCS (Distributed Control System): Control level [L1 ]
5. Production Process: Field level [L0]

From the information technology perspective in operation, levels Two to Four can be classified as IT (Information Technology) and levels Zero to Two as OT (Operational Technology).The current production system is in the direction of being networked vertically and horizontally. In particular, the realization of Industry 4.0 and the utilization of IIoT(Industrial Internet of Things) require communication across hierarchical levels.Many technical colleges use stand-alone PLCs (not networked) for exercises. Unfortunately, this situation is also insufficient for pre-Industrory 4.0 production systems.Therefore, we will introduce a case study of upgrading control system exercises using Omron PLCs, which have been introduced in many cases at KOSEN. Specifically, examples and configurations of PLCs connected by Fieldbus (RS485, RS232C) and Ethernet will be presented to realize system network support. Next, we will offer a case study of IIoT support by connecting Node-Red to a controller. Finally, a cyber security exercise environment and educational materials for ICS will be developed by taking advantage of Omron PLC's features that allow multiple industrial protocols (Modbus, FINS, OPC UA) to be used

This paper introduces examples of advanced control system exercises using OMRON PLCs, which have been introduced in many KOSENs. Specifically, this paper presents a model and configuration of connecting PLCs via fieldbus and Ethernet to realize network compatibility of the system. Next, examples of IIoT (Industrial IoT) support and cyber security training environment and educational materials for ICS (Industrial Control System) will be introduced.
