Product Overview

The Emerson VE6023 Ethernet Switch is an industrial network component designed to support Ethernet connectivity within automation, process control, and industrial communication systems. As control architectures become increasingly distributed, Ethernet networks provide an important communication layer for exchanging information between controllers, I/O systems, operator interfaces, supervisory computers, and other intelligent devices.

An Ethernet switch provides a structured method for connecting multiple network devices. Instead of requiring separate direct communication links between individual devices, connected equipment can communicate through a common switching infrastructure.

The Emerson VE6023 has listed dimensions of 138 × 73 × 115 mm and a listed weight of 0.57 kg. These compact physical characteristics make the unit suitable for consideration in industrial control cabinets and automation equipment where available installation space must be managed carefully.

The exact network capabilities of a specific VE6023 installation should be confirmed against the applicable technical documentation. Port quantity, Ethernet speed, power requirements, management functions, redundancy capabilities, environmental ratings, and other detailed electrical characteristics should not be assumed from the model designation alone.

What Is the Emerson VE6023 Ethernet Switch?

The Emerson VE6023 is an Ethernet Switch used to provide network connectivity between compatible Ethernet-based industrial devices.

Unlike a PLC, the switch does not normally execute the main process-control program. Instead, it belongs to the communication infrastructure that allows different automation devices to exchange information.

A simplified industrial architecture can be represented as:

Field Devices → I/O System → Controller → Ethernet Network → Supervisory System

The VE6023 can operate as part of the Ethernet network within this architecture.

Depending on the system configuration, network-connected equipment may include:

• Industrial controllers
• Remote I/O systems
• HMI panels
• SCADA computers
• Engineering workstations
• Industrial computers
• Ethernet-enabled automation equipment

How Ethernet Switching Supports Automation

Industrial Ethernet communication depends on a network infrastructure capable of interconnecting multiple devices.

A switch receives Ethernet traffic from connected equipment and forwards communication through the appropriate network path.

This allows a controller to communicate with multiple systems without requiring an individual direct physical connection to every device.

For example:

Controller → VE6023 → Remote I/O

or:

Controller → VE6023 → HMI

or:

Controller → VE6023 → SCADA

The actual topology depends on the plant architecture and communication requirements.

A properly designed network can make automation equipment easier to connect, monitor, diagnose, and maintain.

Role in Industrial Control Systems

Industrial automation systems commonly combine several layers of equipment.

Field Layer

Sensors and actuators interact with the physical process.

I/O Layer

I/O systems collect field signals and provide output interfaces.

Control Layer

Controllers process inputs and execute automation logic.

Communication Layer

Ethernet infrastructure connects controllers and other intelligent devices.

Supervisory Layer

HMI and SCADA systems provide visualization and monitoring.

The VE6023 belongs to the communication infrastructure layer.

Its network function can therefore support the exchange of:

• Process data
• Equipment status
• Alarms
• Diagnostics
• Configuration information
• Supervisory information

The actual data and protocols depend on the devices connected to the network.

Industrial Applications

Process Automation

Process plants often contain controllers and I/O equipment distributed across multiple locations.

Ethernet networks allow these systems to exchange information through a structured communication architecture.

Typical applications include:

• Chemical processing
• Oil and gas
• Power generation
• Water treatment
• Wastewater systems
• Pharmaceutical manufacturing
• Food and beverage production
• Industrial utilities

Distributed I/O

Remote I/O stations can be positioned close to field equipment.

This reduces the need to route every field signal back to a central control cabinet.

Where Ethernet communication is supported, a switch can provide the network connection between remote I/O and controllers.

HMI Communication

Operator interfaces require access to controller and process information.

The Ethernet network can provide communication between the control system and HMI equipment.

Typical information includes:

• Process values
• Equipment status
• Alarm conditions
• Diagnostic messages
• Operating parameters

SCADA Communication

SCADA systems collect process information from automation equipment and present it to operators and engineers.

An Ethernet switching infrastructure can support the communication path between controllers and supervisory computers.

Industrial Machine Automation

Ethernet is also commonly used in machine-control architectures to interconnect PLCs, HMIs, remote I/O, drives, and other intelligent devices.

The VE6023 can be evaluated for such applications according to its actual technical specifications.

Network Architecture Considerations

A reliable industrial Ethernet system should be designed as an integrated architecture rather than simply connecting devices together.

Important considerations include:

• Network topology
• Controller locations
• Remote I/O locations
• HMI connections
• SCADA infrastructure
• Engineering access
• Cable routing
• Power distribution
• Network segmentation
• Maintenance requirements
