Schneider TSXETG100: An Ethernet-to-Serial Gateway for TSX Micro PLCs
The Schneider TSXETG100 serves as a vital communication bridge within the TSX Micro PLC family. It operates as an Ethernet Modbus gateway, enabling seamless integration of serial Modbus devices into modern Ethernet networks. This module supports a rated supply voltage of 24 V DC, making it suitable for standard industrial control panels.
Core Communication Capabilities
This gateway handles both Ethernet and serial protocols with ease. On the Ethernet side, it supports Modbus TCP/IP, HTTP, FTP, SNMP, and ARP. This broad protocol support allows for flexible integration with SCADA systems, HMIs, and enterprise-level software. For serial communication, it supports Modbus RTU and ASCII protocols, ensuring compatibility with a wide range of legacy field devices.
Connectivity options include an RJ45 port for 10/100 Mbps Ethernet networks. For serial links, it offers both RS485 (57.6 kbps) and RS232 (38.4 kbps) interfaces. This dual-interface design allows you to connect up to 32 devices on the Modbus serial link, providing significant scalability for your automation architecture.
Diagnostics and Web Services
The TSXETG100 includes a built-in web server that provides predefined web pages for diagnostics. You can easily monitor the status of both Ethernet and Modbus links, access the list of connected devices, and read Modbus registers. This feature simplifies troubleshooting and reduces downtime. Additionally, the module supports SNMP agents, enabling centralized network management.
Security is also addressed with a miniature firewall that performs IP address filtering and password protection. The module also supports BOOTP and FDR client functions, simplifying IP address assignment and device replacement.
Physical and Environmental Specifications
This gateway mounts on a symmetrical DIN rail, ensuring straightforward installation. It measures 72 x 81 x 76 mm and weighs 1.36 kg. The operating temperature range is 32 to 140 °F (0 to 60 °C), and it can handle relative humidity from 5% to 95% without condensation. With an IP30 rating, it is protected against dust and solid objects larger than 2.5 mm.
The module features clear local signaling with three LEDs for serial link status (RS485, RX, TX) and four LEDs for Ethernet activity (LK, RX, TX, 100). This allows for quick visual checks of communication health.
Standards and Certifications
The Schneider TSXETG100 meets essential industry standards, including EN 61000-4-2/3/4/5/6/8, UL 508, and CSA C22.2 No 14-M91. It also complies with EN 55022 and FCC class A for electromagnetic emissions. The module holds cUL and UL certifications, ensuring safety and reliability in demanding environments.
For engineers seeking to modernize legacy serial networks or integrate TSX Micro PLCs into new Ethernet-based systems, the TSXETG100 offers a robust and secure solution. Its combination of protocol support, web-based diagnostics, and compact design makes it a practical choice for many industrial applications.
