Schneider 100BASE-TXTSXETG100 Ethernet Modbus Gateway

Product Description

The TSXETG100 from Schneider Electric’s ConneXium range is an industrial Ethernet gateway designed to bridge Modbus serial devices with Ethernet-based TCP/IP networks. Although no longer in production, this unit remains widely deployed in legacy Modicon architectures where reliable protocol conversion and network transparency are required.

Engineered for deterministic communication, the gateway enables seamless data exchange between Modbus RTU/ASCII field devices and higher-level Ethernet systems, supporting integration into SCADA, PLC, and distributed control environments.

• Migration of legacy serial networks to TCP/IP infrastructure
• Remote monitoring of PLCs, drives, and instrumentation
• Industrial energy management and data acquisition systems

FAQ

Q: Is the TSXETG100 still supported by Schneider Electric?
A: No, the product has reached end-of-service status. Technical support and spare parts availability may be limited.

Q: Can it function as both Modbus master and slave?
A: Yes, it supports both roles depending on configuration, enabling flexible communication schemes.

Q: Does it support secure industrial networking?
A: It includes basic security features such as IP filtering and password protection, but it does not meet modern cybersecurity standards.

Q: What should be considered for replacement?
A: Migration typically involves newer Ethernet gateways or industrial routers with enhanced security and higher serial throughput. Compatibility with Modbus TCP/RTU should be verified.
