The Schneider TCSESU043F1N0 is a ConneXium unmanaged switch for connecting Ethernet-based devices in industrial automation networks. It is intended for applications where several controllers, operator interfaces, distributed devices, or other Ethernet equipment need to communicate through a simple industrial network infrastructure.
In a typical control cabinet, the switch can be used as a compact connection point between a PLC and devices such as an HMI, remote I/O station, drive, or engineering workstation. Unlike a managed switch, it does not require network-management configuration for basic switching operation, which can simplify installation in straightforward Ethernet networks.
The TCSESU043F1N0 is particularly suitable for machine-level and cabinet-level networks where the communication structure is relatively simple. Once the Ethernet connections are established, the switch forwards network traffic between connected devices without becoming part of the application logic.
It can also be used as an expansion point when additional Ethernet devices need to be added to an existing automation network. Its compact form makes it practical for installations where cabinet space is limited.

The TCSESU043F1N0 receives Ethernet frames from connected devices and forwards them through the appropriate Ethernet connection. The switch performs the communication forwarding automatically without requiring the network-management functions associated with a managed switch.
A typical connection can be represented as:
PLC / Controller → TCSESU043F1N0 → HMI / Remote I/O / Drive / Engineering Device
For example, when a PLC sends Ethernet data to a remote device, the switch receives the network traffic from the PLC connection and forwards it toward the connected destination. Return communication follows the same basic switching process.
Because the switch is unmanaged, the installation process is generally straightforward: connect the appropriate Ethernet devices, establish the physical network connections, and configure the connected automation equipment according to the requirements of the control system.
The TCSESU043F1N0 operates at the network infrastructure level of an automation architecture. It provides the physical Ethernet switching function while the connected PLC, HMI, I/O, or drive equipment handles its own application and control tasks.
PLC / Controller → TCSESU043F1N0 → Ethernet Automation Devices
| System Element | Function |
|---|---|
| PLC / Controller | Executes control logic and exchanges automation data |
| TCSESU043F1N0 | 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 motor-control commands and status information |
| Engineering Workstation | Supports configuration and commissioning |
| Upstream Network | Provides communication with other control or supervisory equipment |
The switch is therefore best viewed as a simple Ethernet connection layer between automation devices rather than a controller or protocol-processing unit.
| Application | Typical Use |
|---|---|
| Machine Automation | Connects PLCs with HMIs, drives, and Ethernet-based machine devices |
| Control Cabinets | Provides a central Ethernet connection point for cabinet equipment |
| Remote I/O | Connects distributed I/O stations to controllers through Ethernet |
| HMI Networks | Links operator interfaces with PLCs and other automation devices |
| Drive Networks | Provides Ethernet connections for networked motor-control equipment |
| Packaging Machinery | Supports communication between machine controllers and distributed devices |
| Manufacturing Equipment | Connects Ethernet-enabled automation components within a machine |
| Network Expansion | Adds additional Ethernet connection capacity to an existing automation network |

The TCSESU043F1N0 is used as an unmanaged Ethernet switch in industrial automation systems. It connects multiple Ethernet-based devices and forwards communication traffic between them without requiring switch-level network configuration.
No. As an unmanaged switch, it does not require the type of network-management configuration associated with managed Ethernet switches for basic switching operation. The connected automation devices still need their own appropriate network settings.
Yes. It can be used as the Ethernet connection point between compatible PLCs, HMIs, remote I/O equipment, drives, and other Ethernet-based automation devices.
Check the power connection, Ethernet cables, connectors, link indicators, and the network settings of the connected devices. Also verify that the intended network topology has been wired correctly and that there are no duplicate network addresses among the connected devices.
