The Schneider TCSESU083FN0 is a ConneXium unmanaged switch used to provide Ethernet connectivity between multiple devices in an industrial automation network. It is suited to control cabinets, machine networks, and distributed automation systems where PLCs, HMIs, remote I/O, drives, and other Ethernet-based equipment need to communicate through a common network connection.
In a typical control system, the switch serves as a local Ethernet connection point between the controller and several networked devices. It forwards Ethernet traffic between connected nodes without becoming involved in PLC program execution or process signal handling. This makes it suitable for straightforward network structures where dedicated switch-level management is not required.
The unmanaged architecture is useful for machine-level applications and smaller automation networks where the main requirement is to establish additional Ethernet connections without introducing a separate network configuration layer. It can also be used to extend an existing Ethernet infrastructure when additional devices need to be connected.
Within a ConneXium-based installation, the TCSESU083FN0 can operate alongside controllers, operator interfaces, remote I/O, drives, and other Ethernet infrastructure. Its role remains focused on network connectivity, leaving control and application functions to the connected automation equipment.

The TCSESU083FN0 receives Ethernet frames from connected automation devices and forwards the traffic toward the appropriate network destination. The switching process occurs automatically, allowing several Ethernet nodes to communicate through the same network infrastructure.
A typical communication path is:
PLC / Controller → TCSESU083FN0 → HMI / Remote I/O / Drive / Other Ethernet Device
For example, a PLC may exchange data with a remote I/O station through the switch. The Ethernet traffic enters through the controller connection and is forwarded to the required network device. Data returned by the remote station follows the reverse communication path.
As an unmanaged switch, the TCSESU083FN0 does not require a switch-level configuration process for normal Ethernet forwarding. Network parameters such as IP addressing remain the responsibility of the connected Ethernet devices and the overall automation network design.
The TCSESU083FN0 functions as a network connectivity component within the Ethernet layer of an automation architecture. It links multiple Ethernet devices while the PLC, HMI, drive, I/O system, and supervisory equipment perform their respective control and application functions.
PLC / Controller → TCSESU083FN0 → Distributed Ethernet Devices → Supervisory Network
| System Element | Function |
|---|---|
| PLC / Controller | Executes control logic and exchanges automation data |
| TCSESU083FN0 | Forwards Ethernet traffic between connected devices |
| Remote I/O | Handles distributed field inputs and outputs |
| HMI | Provides operator monitoring and control |
| Ethernet Drive | Exchanges control commands, status, and diagnostic information |
| Engineering Workstation | Supports configuration and commissioning of automation equipment |
| Supervisory System | Collects process information and provides higher-level monitoring |
The switch therefore provides the communication infrastructure needed for Ethernet-based device integration without processing the automation application itself.

The TCSESU083FN0 is used as an unmanaged Ethernet switch in industrial automation systems. It provides Ethernet connectivity between multiple networked automation devices.
As an unmanaged switch, it does not require the same switch-level configuration process as a managed Ethernet switch for basic forwarding operation. The connected automation devices still need their own appropriate network settings.
Yes. It can serve as the Ethernet connection point between compatible PLCs, remote I/O stations, HMIs, drives, and other Ethernet-based devices within an automation network.
Check the power supply, Ethernet cables, connectors, link indicators, device network settings, and cable connections at both ends. If the physical layer is normal, verify the network addressing and communication configuration of the affected automation devices.
