Case Study at EVN Macedonia: Secure LAN-Based meter communication via Industrial DIN-Rail Router

🚀 Modernizing Utility Metering at EVN Macedonia

We’re excited to share insights from the recent case study with EVN Macedonia, a national electricity distribution and supply operator. This real-world deployment demonstrates how industrial-grade communications solutions can transform legacy infrastructure into secure, reliable, and scalable grid assets — without costly meter replacements.

🔧 The Challenge

EVN faced a classic utility modernization issue — fleets of existing RS485 meters with no standardized way to integrate them into an IP-based network while meeting strict utility-grade cybersecurity requirements. Traditional IT routers and cellular modems either lacked industrial interfaces or did not comply with EVN’s security policies.

🛠 The Solution

WM Systems delivered a purpose-built industrial DIN-rail router with secure features.

Industrial routers are no longer “just routers.”

They’re becoming the most strategic compute nodes in Industrial IoT.

Across utilities, manufacturing, and energy systems, engineers are shifting critical logic from the cloud to the edge. And for good reason: real-time decisions, bandwidth reduction, higher reliability, and tighter data security all happen faster when applications run directly on the router.

In our latest article, we explore:

• Why edge processing is outperforming cloud-only IIoT setups

• How running custom applications on routers improves resilience

• What this means for protocol handling, analytics, and automation

• Why app-enabled routers reduce total system cost

• How this shift prepares industrial deployments for the next decade

At WM Systems, we’re already building for this future.

Our upcoming router variant will allow customers to develop, deploy and manage their own applications directly on the device — turning the router into a true intelligent edge unit.

If you're working on advanced IIoT, utilities, remote infrastructure, or industrial automation, this trend will shape your next system design.
