Control System Migrations & Upgrades

Obsolete control systems can be modernised without treating the plant as a greenfield project. syTechnologies plans migrations around the existing process, field I/O, communications, production constraints and available shutdown windows.

Migration services

• Legacy PLC replacement and software conversion.
• Remote I/O and network migration.
• SCADA/HMI version upgrades and application migration.
• Server and operating-system refreshes.
• Industrial-network conversion and gateway integration.
• Phased cutover strategies for running plants.
• Simulation, FAT and pre-commissioning validation.
• Commissioning and post-cutover support.

Typical modernisation paths

• Schneider legacy Quantum systems to Modicon M580.
• Siemens S7-300 / S7-400 systems to S7-1500.
• Legacy Wonderware / Citect applications to current AVEVA platforms.
• Profibus and serial device networks to modern Ethernet-based architectures where practical.

The objective is not simply to replace hardware. The migration should leave the plant with a supportable architecture, clear documentation and a tested path from the old system to the new one.
