April 9, 2026 — Modernizing legacy Fieldbus installations has long been a challenge, especially in environments built around PLC architectures. Replacing failed or unreliable old drives often requires PLC code changes, specialized tools and extended downtime which are scarce resources at best or even resources no longer available.
A joint solution from Siemens and ElectroMatic, enabled by Hilscher, is an example that answers that challenge. By using pre-configured communication modules based on Hilscher’s multiprotocol technology, netX, Siemens SINAMICS drives can be integrated into existing DeviceNet networks without modifying the PLC program. At the core is Hilscher’s ability to bridge different industrial protocols on a single platform. This technology enables seamless communication between Siemens drive systems and Rockwell-controlled networks, ensuring interoperability without disruption.
The result is a practical approach to brownfield modernization: reduced downtime, simplified maintenance and greater flexibility in component selection. Instead of replacing entire systems, operators can now upgrade, step by step combining the strengths and economies of both ecosystems.
This is industrial communication at its best: open, flexible and built for coexistence.
