Connecting TSX Micro PLCs to Modern Networks

Industrial facilities increasingly rely on seamless communication between legacy PLCs and modern Ethernet-based systems. The Schneider Electric TSXETG100 addresses this need by serving as a gateway between TSX Micro PLCs and TCP/IP networks. This module enables data exchange without requiring a complete control system overhaul.

For maintenance teams and system integrators, the TSXETG100 offers a practical path to improve machine visibility and data collection. Its compact design and DIN rail mounting simplify installation in existing panels. This article examines the module's specifications, applications, and value for industrial operations.

Product Overview: TSXETG100 from Schneider Electric

The TSXETG100 is part of the TSX Micro PLCs product line and functions as an Ethernet Modbus gateway/router. It is designed for all products compatible with the Modbus standard, making it a versatile communication bridge. The module carries the ConneXium range designation and supports the Transparent Ready concept.

Rated for a 24 V DC supply voltage, the TSXETG100 integrates into standard industrial control panels. It provides both Ethernet and serial connectivity, allowing legacy Modbus RTU devices to communicate over modern TCP/IP networks. This capability is essential for retrofitting older machinery with IIoT monitoring.

Technical Specifications and Performance

The TSXETG100 supports multiple Ethernet protocols, including Modbus TCP/IP, HTTP, FTP, SNMP, and ARP. For serial communication, it handles Modbus RTU and ASCII protocols. The Ethernet port is an RJ45 connector supporting 10/100 Mbps speeds, while serial links include RS485 at 57.6 kbps and RS232 at 38.4 kbps.

• Rated Supply Voltage: 24 V DC
• Ethernet Connection: RJ45 10/100 Mbps
• Serial Links: RS485 (57.6 kbps), RS232 (38.4 kbps)
• Max Devices on Modbus Serial Link: Less than 32
• Operating Temperature: 32-140 °F (0-60 °C)
• Relative Humidity: 5-95% at 104 °F (40 °C) without condensation
• IP Degree of Protection: IP30
• Dimensions: 2.8 x 3.2 x 3.0 in (72 x 81 x 76 mm)

The module includes a miniature firewall for IP address filtering and password protection. It also supports BOOTP protocol and FDR client for network configuration. Local signaling uses three LEDs for serial link status and four LEDs for Ethernet activity, aiding quick diagnostics.

Applications in Industrial Environments

The TSXETG100 is well-suited for applications where TSX Micro PLCs must report data to higher-level systems. For example, in a packaging line, the gateway can stream production counts and alarm statuses to a central SCADA system via Modbus TCP/IP. This enables real-time performance monitoring without altering existing PLC logic.

Another common use is in remote pumping stations, where the module's RS485 link connects to legacy flow meters and pressure transmitters. The gateway then publishes this data over Ethernet to a control room, reducing manual rounds and improving response times. Its wide operating temperature range of 32-140 °F ensures reliable operation in harsh environments.

Illustrative Customer Scenario

Consider a mid-sized food processing plant that operates several TSX Micro PLCs controlling mixing and filling equipment. The plant manager wants to collect production data centrally but lacks a network interface on the PLCs. By installing the TSXETG100 on each PLC, the plant enables Modbus TCP/IP communication to a new MES system.

As a result, the plant gains visibility into batch completion times, equipment utilization, and fault codes. Maintenance staff can access predefined web pages to diagnose Ethernet and Modbus links, reducing troubleshooting time. This scenario demonstrates how the TSXETG100 delivers practical IIoT benefits with minimal disruption.

Compatibility and Integration Considerations

The TSXETG100 is designed for all products compatible with the Modbus standard, making it a flexible choice for mixed-vendor environments. It supports both Modbus RTU over serial and Modbus TCP/IP over Ethernet, bridging legacy and modern systems. The module also offers web services for diagnostics via predefined web pages.

For network management, the TSXETG100 includes an SNMP agent, allowing integration with standard network monitoring tools. The built-in firewall and password protection enhance security, which is critical for industrial networks. When comparing with similar gateways, the TSXETG100 stands out for its dual-protocol support and compact form factor.

Market Impact and Business Value

Deploying the TSXETG100 can reduce downtime by enabling faster diagnostics and remote monitoring. The module's support for SNMP and web-based diagnostics allows maintenance teams to identify issues without physical inspection. This translates to lower labor costs and improved equipment availability.

Additionally, the TSXETG100's ability to connect up to 32 devices on a Modbus serial link reduces the need for multiple gateways. Its 24 V DC supply aligns with common industrial power systems, simplifying installation. For oil and gas operations, the module's robust temperature range and IP30 protection ensure dependable performance in demanding settings.
