CONCRETE TECHNOLOGY68 CPI %u2013 Concrete Plant International %u2013 1 | 2026 www.cpi-worldwide.comAs the concrete industry evolves toward higher levels of automation and digital integration, upgrading legacy control systems becomes not only a matter of convenience but a strategic advantage. Wiggert USA recently upgraded the batching control system at Capital Precast, a U.S.-based precast concrete producer, to WCS V11 (Wiggert Control System Version 11) %u2014 a major step toward improving plantwide efficiency, reliability and usability.Capital Precast operates multiple batch plants, some of which were equipped with older-generation control systems that had become increasingly difficult to maintain. Some others used third-party control systems.The biggest problems arose from the limited availability of spare parts, the varying levels of experience among operators at the different plants, outdated moisture probes and associated software and manual workarounds that slowed down production.The WCS V11 platform offered a seamless, customisable upgrade of the batching control system. WCS V11 was developed internally by Wiggert in Germany, where it continues to be developed. Based on a Siemens PLC and Microsoft Windows, WCS V11 offers a user-friendly and powerful control environment.Key features include:%u2022 Replacement of DK scale units with modern PLC-based scale units%u2022 Real-time monitoring and remote diagnostics%u2022 Modular, app-based structure for flexible configuration of plant functionsCapital Precast now benefits from uniformity across all its plants. Operators can easily switch between locations thanks to a consistent, user-friendly graphical interface and logic. In addition, the simplified control concept has reduced the training time required.Increased efficiency and flexibility through modernisation of the batching control system at Capital PrecastWiggert & Co.
