Application Scenarios
A regional refinery needed to expand its DeltaV control room from a single operator station to a redundant pair while simultaneously bringing three remote I/O cabinets onto the same network at distances of 80 meters, 1.2 kilometers, and 6.4 kilometers. Using separate switches for each media type would have created three vendor support contracts and a fragmented diagnostic picture. The VE6022P1 solved this in a single rack unit: VE6025 copper SFPs handled the workstation and server legs, VE6023 multimode fiber covered the near cabinet, and VE6024 single-mode fiber reached the distant one. The port mix was configured once, and the ACN remained a single Emerson-supported fabric. When a fiber splice degraded months later, the fault appeared as a single link-down event on one cage rather than a broadcast storm sweeping the control room.

Technical Principles and Innovative Values
Innovation Point 1: SFP-Only Chassis Design for Media Flexibility. The VE6022P1 ships as an empty chassis with twelve SFP cages and no fixed copper ports. This is deliberate design logic rather than a limitation: a process plant rarely needs twelve identical ports, and a fixed copper switch would force either media converters or copper runs constrained by the 100-meter distance limit. The VE6022P1 allows one chassis to carry short cabinet jumpers, plant-floor multimode fiber, and long single-mode links side by side, all within the Emerson-qualified envelope.
Innovation Point 2: ACN-Native Redundancy Without Spanning Tree. Unlike general-purpose managed switches that rely on STP or dynamic routing for path management, the VE6022P1 operates within the DeltaV ACN where redundancy behavior is governed by the DeltaV network design itself. This simplifies configuration and eliminates the learning curve associated with spanning-tree tuning in a process control environment. The switch functions as a deterministic Layer 2 fabric element, not a standalone routing device.
Innovation Point 3: Cisco-Derived Architecture with Emerson Qualification. The VE6022P1 is based on the Cisco Catalyst 3750G-12S-S platform, inheriting Cisco’s SFP compatibility, CLI behavior, and stacking characteristics. Emerson qualifies the unit for DeltaV service, adding industrial-grade validation and system-level support that a generic Cisco switch would not carry. For plants already familiar with Cisco networking, this reduces operational friction while maintaining the Emerson support contract.
