IEC 61850 to OPC/DDE Integration

AX-S4 61850

AX-S4 61850 provides seamless access to real-time IEC 61850 data for any Windows application supporting OPC Data Access (DA) and DDE interfaces — an IEC 61850 client, server, and GOOSE publisher/subscriber in one easy-to-use package.

AX-S4 61850: circuit board representing IEC 61850 data access

Simplify 
​Integration

One package delivers IEC 61850 client, server, and GOOSE pub/sub access to OPC and DDE, with no custom driver development required.

Reduce 
​Configuration Effort

Automatic quality and timestamp mapping plus simplified single-object writes cut setup time for OPC engineers.

Flexible 
​Deployment

Connect up to eight IEC 61850 IPs per device with built-in failover, retry, and keep-alive for reliable field operation.

What AX-S4 61850 Delivers

Your SCADA, EMS, or DMS wasn't built for IEC 61850. AX-S4 61850 closes that gap, providing a complete IEC 61850 client, server, and GOOSE publisher/subscriber interface to any Windows application that supports OPC Data Access — no custom protocol coding, no changes to existing infrastructure.

  • IEC 61850 Client – OPC/DDE Server
  • GOOSE Publisher/Subscriber – OPC Server
  • IEC 61850 Server – OPC Client
  • Interactive Object Explorer for browsing, testing, configuration, and debug
  • Automatic report subscription and dataset handling, with reports re-enabling on their own after power cycles or disconnects
  • Automatic quality and timestamp mapping to OPC quality and timestamps
  • Simplified Direct and SBO control operations via single-object writes

Technical Specifications

AX-S4 61850 runs as a single Windows installation supporting multiple deployment patterns — SCADA gateway, data concentrator, IEC 61850 proxy server, or device simulator — with built-in resilience for continuous connectivity.
    • OPC DA V2.05a and V3.0 compliant, plus DDE support
    • Runs on currently supported Microsoft Windows versions
    • Up to 8 IP addresses per remote device, attempted automatically for failover
    • Automatic retry and timeout, with keep-alive for report-only associations
    • Association control exposed to OPC clients for manual override
    • IEC 62351 security — TLS 1.2 encryption and X.509 certificate authentication, included at no additional cost
    • Licensed per computer — no device limit, no tag limit
