Functional Description

The WES5120 module extends the D20 RTU’s communication capability beyond legacy serial links to support modern Ethernet‑based networks. This makes it significantly easier to connect RTUs to upstream control systems such as SCADA master stations, MES/EMS systems, and even remote enterprise platforms.

Once installed on the D20 backplane, it acts as a gateway between field I/O logic and networked controllers, enabling data exchange, command relay, and diagnostics over IP networks. This Ethernet support brings higher throughput and improved timing for real‑time monitoring and control compared to older communication methods.

Structure & Integration

Physically, the WES5120 spans one or more backplane slots in a WESDAC D20 cabinet. It incorporates industrial connectors (including RJ45 Ethernet ports) and interfaces with the system bus to deliver coherent communication services. Its compact design makes retrofits straightforward in existing D20 installations.
