The Schneider TCSESU053FN0 is a ConneXium unmanaged switch used to connect multiple Ethernet-based devices within an industrial automation network. It is suited to machine-level control systems, automation cabinets, and distributed equipment where PLCs, HMIs, remote I/O, drives, and other Ethernet devices need to communicate through a common network connection.
In a typical automation installation, the switch provides a local Ethernet connection point between the controller and several networked devices. It forwards Ethernet traffic between connected nodes without participating in PLC program execution, I/O processing, or application-level control.
Its unmanaged architecture keeps the network infrastructure straightforward. Once the physical Ethernet connections are established, the switch can forward traffic without requiring the switch-level configuration associated with managed network equipment. This makes it suitable for relatively simple industrial Ethernet networks and machine-level applications.
The TCSESU053FN0 can also be used when an existing control system needs additional Ethernet connection capacity. It can sit alongside Schneider automation equipment and other ConneXium network components while leaving network addressing and application communication settings to the connected devices.

The TCSESU053FN0 receives Ethernet frames from connected devices and forwards them through the appropriate network connection. The switching function allows several Ethernet nodes to communicate through a shared industrial network infrastructure.
A typical communication path is:
PLC / Controller → TCSESU053FN0 → HMI / Remote I/O / Drive / Other Ethernet Device
For example, when a PLC communicates with a remote Ethernet I/O station, the network traffic travels from the controller to the switch and is forwarded toward the intended device. The response from the I/O station follows the corresponding Ethernet path back to the controller.
Because the TCSESU053FN0 is an unmanaged switch, basic switching does not require switch-level network configuration. The connected PLCs, HMIs, drives, and other Ethernet devices retain responsibility for their own communication and network settings.
The TCSESU053FN0 operates within the Ethernet infrastructure layer of an automation architecture. It provides the communication path between connected network nodes while the PLC, HMI, remote I/O, drive, and supervisory systems perform their respective application functions.
PLC / Controller → TCSESU053FN0 → Distributed Ethernet Devices → Supervisory System
| System Element | Function |
|---|---|
| PLC / Controller | Executes control logic and exchanges automation data |
| TCSESU053FN0 | Forwards Ethernet traffic between connected network devices |
| Remote I/O | Handles distributed field inputs and outputs |
| HMI | Provides operator monitoring and control |
| Ethernet Drive | Exchanges drive commands, status, and diagnostic information |

The TCSESU053FN0 is used as an unmanaged Ethernet switch in industrial automation systems. It connects multiple Ethernet-based devices and forwards communication traffic between them.
No switch-level configuration is normally required for basic unmanaged switching. The connected automation devices still need their own appropriate Ethernet and network settings.
Yes. It can be used as a common Ethernet connection point for compatible PLCs, HMIs, drives, remote I/O stations, and other networked automation equipment.
Check the switch power connection, Ethernet cables, connectors, link status, and the network settings of the connected devices. If one device is affected while other connections remain operational, inspect that device’s cable, port connection, and network configuration first.
