In order for thermal power plants to operate stably in response to high demand for electricity and to ensure sustainable operation over the medium to long term, maintenance activities not only for the main facilities but also for the control system for their monitoring and control are extremely important. Maintenance work for control systems is required to be planned to cause as little disruption to the facility operations as possible. Maintenance of the control system includes periodic replacement and upgrade work for stable operation and dealing with the discontinuation of production of its electronic components. We have developed an FXtoLS adapter that enables efficient upgrade of only the input/output communication part of a control device so that maintenance work can be performed during an inspection shutdown period of the main facility side. In addition, this report presents the latest solution of DIASYS Netmation, a cybersecurity measure based on multi-layer defense, to prepare for the increased risk of cyber-attacks on control systems in operation due to the development of IoT technology.
