TSXETG100 | Schneider Modicon Quantum | ConneXium Ethernet Modbus Gateway/Router

Schneider Electric TSXETG100 ConneXium Ethernet Modbus Gateway/Router — 10/100Mbps, Class B10, PoE

The TSXETG100 is a ConneXium Ethernet Modbus gateway/router manufactured by Schneider Electric under the Telemecanique brand. It bridges Modbus RTU/ASCII serial devices to Ethernet TCP/IP networks, enabling legacy Modbus equipment to integrate into modern industrial Ethernet infrastructures. The device features a Class B10 web server for diagnostics, SNMP agent for device management, and supports Power over Ethernet (PoE IEEE 802.3af) for flexible power options.

Installation Guide

1. Mount the TSXETG100 on a 35 mm symmetrical DIN rail in the control cabinet.
2. Connect 24 VDC power to the control power terminal (or use PoE if switch supports IEEE 802.3af).
3. Connect the RJ45 Ethernet port to the 10/100 Mbps network switch using standard Cat 5e/6 cable.
4. Connect Modbus RTU/ASCII serial devices to the RS-485 terminal block (5-way removable) or RS-232 RJ45 port.
5. Configure Ethernet settings (IP address, subnet mask, gateway) via web browser using an Ethernet crossover cable, or via HyperTerminal using a null modem cable (TCSEAK0100 configuration kit sold separately).
6. Configure serial port parameters (baud rate, parity, stop bits) to match connected Modbus devices.
7. Configure the device list (Modbus slave addresses mapped to IP addresses).
8. Verify LED indicators: LK (link active), Ethernet RX/TX, Serial RX/TX.

FAQ

Q: Is TSXETG100 still in production?
A: No. The TSXETG100 and EGX100 are obsolete. Schneider Electric recommends the EcoStruxure Panel Server product line as the replacement.

Q: What is the difference between TSXETG100 and EGX100?
A: Both are physically identical but branded differently. EGX100 (Square D brand) supports Modbus RTU, Jbus, PowerLogic (SY/MAX), and Modbus ASCII. TSXETG100 (Telemecanique brand) supports only Modbus RTU and Modbus ASCII. PowerLogic legacy devices (CM100/200, CM2000) and SEPAM relays cannot communicate through TSXETG100.

Q: Can TSXETG100 be powered by PoE?
A: Yes. The device supports Power over Ethernet (IEEE 802.3af) via the RJ45 Ethernet port, eliminating the need for a separate 24 VDC power supply if the switch supports PoE.

Q: How many Modbus devices can connect to TSXETG100?
A: Up to 32 Modbus serial devices on a single RS-485 network.

Q: What is Class B10 web server?
A: Class B10 is Schneider Electric's classification for embedded web servers with predefined diagnostic pages, device lists, and Modbus register read access. It does not support custom web page development.

Q: Is TSXETG100 compatible with Windows 10/11?
A: The TSXETG100 is a standalone gateway and does not require a specific Windows version. However, the configuration tools referenced in legacy documentation support Windows XP, Vista, Server 2003/2008 R2, and Windows 7. Modern browsers can access the web server directly.

Selection Tips

• Legacy Modbus to Ethernet gateway: TSXETG100 (if existing stock available)
• Replacement for new installations: EcoStruxure Panel Server series
• PowerLogic/SY/MAX compatibility: Use EGX100 (also obsolete) instead of TSXETG100
• Always verify: Serial protocol (Modbus RTU vs ASCII), baud rate, number of devices, and Ethernet network configuration
• Consider PoE: If your switch supports IEEE 802.3af, PoE eliminates separate power wiring.
