【Common Issues】 Aging DCS systems face difficulties in maintenance due to the end of parts supply and rising maintenance costs, and because they are proprietary systems, modifications and feature additions rely heavily on the manufacturer, leading to a lack of flexibility. Additionally, system updates that include operation panels (HMI) in explosion-proof areas require coordination among multiple vendors, raising concerns about the dispersion of construction responsibility and design inconsistencies. There are many cases where companies hesitate to proceed with updates due to cost and the challenges of addressing hazardous locations. 【Solution Approach】 Our company offers a solution that replaces DCS with general-purpose PLCs and SCADA, achieving both cost reduction and flexible operations. We meticulously plan engineering that includes modifications to existing panels and I/O conversions to ensure that system replacements are completed within the downtime period. Furthermore, by adopting open technologies, customers can perform small-scale modifications and adjustments themselves after implementation, freeing them from vendor lock-in. Additionally, by simultaneously updating explosion-proof PCs and touch panels from our own product lineup, we can comprehensively refresh the entire system, including hazardous areas.
