Introduction
A production line manager once faced a familiar problem: the TSX Micro PLC controlling a packaging station could not share real-time data with the plant’s supervisory system. Hardwired I/O offered no path for remote diagnostics or production reporting. The missing link was an Ethernet communication module. The Schneider Electric TSXETY4103 solves exactly this challenge. It is an Ethernet TCP/IP module built for the TSX Micro PLCs series, packaged in a standard module format that slots directly into the existing rack. Instead of replacing the entire controller, engineers add this module and gain 10/100 Mbit/s networking, Modbus TCP messaging, and web-based diagnostics. The module draws 360 mA at 5 V DC from the rack power supply, so no separate power wiring is required. For plants running legacy Schneider automation, this is a practical upgrade path that protects the original investment.
Technical Specifications
The TSXETY4103 delivers a focused set of communication features. The physical interface uses an RJ45 connector supporting 10BASE-T/100BASE-TX over one twisted pair. Transmission rates of 10 or 100 Mbit/s auto-negotiate to match network conditions. The module supports up to 64 concurrent connections, which is ample for simultaneous programming, HMI, and SCADA traffic. Communication protocols include Modbus TCP and Uni-Telway. Communication services cover bandwidth management, FDR server, Global Data, I/O scanning, Modbus TCP messaging, SMTP e-mail notification, SNMP agent, and Uni-TE messaging. A transparent ready class B30 web server provides a rack viewer and data editor accessible via PC terminal. Four LEDs on the front panel show collision detection (COL), network status (RUN), port fault (ERR), and transmission/reception activity (TX/TR). The module carries CE marking and meets CSA 1010-1, FM Class 1 Division 2 (Groups A, B, C, D), EN 61131-2, and UL 508 standards. It operates in ambient temperatures from 0 to 60 °C and relative humidity of 10 to 95 % at 60 °C without condensation. Protection rating is IP20. Net weight is 0.34 kg.
Upgrade Path for Legacy TSX Micro Systems
Angle D: Replacement and upgrade guide. Many facilities still rely on TSX Micro PLCs for discrete manufacturing, material handling, and utility monitoring. These controllers are robust, but their native communication ports often limit data exchange. The TSXETY4103 acts as a bridge. By adding this module, a plant can connect the PLC to an Ethernet network without replacing the CPU, I/O cards, or wiring. The module works with PL7 Pro and Unity Pro programming environments, so existing engineering workflows remain intact. For maintenance teams, this means minimal downtime during installation. The rack viewer and data editor web features allow technicians to inspect module status from a PC terminal, reducing the need for physical access to the cabinet. The SMTP e-mail notification service can alert staff to fault conditions, while the SNMP agent supports integration with network management systems. In a typical upgrade, the module is inserted into a free slot, the RJ45 cable is connected, and the IP address is configured through the programming software. The result is a TSX Micro PLC that participates fully in modern plant networks.
Installation and Setup
Installing the TSXETY4103 follows the standard procedure for TSX Micro rack modules. With the rack power off, slide the module into an available slot and secure it according to the rack documentation. The module receives power from the rack supply, so no external power connections are needed. Connect the RJ45 network cable to the front port. After power-up, verify the LEDs: RUN indicates network status, ERR shows port faults, COL detects collisions, and TX/TR flashes during transmission and reception. Configure the module using PL7 Pro or Unity Pro. Set the IP address, subnet mask, and gateway to match the plant network. Enable the required services such as Modbus TCP messaging, I/O scanning, or SMTP e-mail notification. For web server access, assign a compatible IP address and open a browser from a PC terminal on the same network. Always follow Schneider Electric’s installation manual and local electrical codes. Do not attempt to modify the module hardware.
Maintenance and Reliability
The TSXETY4103 has no moving parts, so wear is minimal. Routine maintenance focuses on environmental and connection checks. Inspect the RJ45 connector and cable for damage or strain every six months. Verify that the cabinet temperature stays within the 0 to 60 °C operating range. Keep humidity below 95 % at 60 °C without condensation. Clean the module exterior only with a dry, soft cloth when the rack is powered down. Do not use solvents or open the housing. Check the LEDs periodically; a persistent ERR LED may indicate a network fault or cable issue. The SNMP agent can send traps to a network management system, enabling proactive monitoring. Because the module draws only 360 mA at 5 V DC, it adds negligible load to the rack power supply. Following these practices helps maximize uptime and protect the automation investment.
Compatibility and Integration
The TSXETY4103 integrates with TSX Micro PLCs and is compatible with PL7 Pro and Unity Pro software. It communicates over Modbus TCP and Uni-Telway protocols. The module supports up to 64 connections, allowing simultaneous communication with HMIs, SCADA systems, and programming terminals. The transparent ready class B30 web server provides a rack viewer and data editor, which can be accessed from any PC with a standard browser. The FDR server function supports fault device replacement, simplifying maintenance when a module needs to be swapped. Global Data and I/O scanning enable efficient data exchange between PLCs. The SNMP agent allows integration into existing network management platforms. For plants using Modbus TCP, the module acts as a server or client, depending on configuration. This flexibility makes it suitable for both new network designs and upgrades of existing TSX Micro installations.
Selection Guide
Before purchasing the TSXETY4103, verify that your PLC rack is part of the TSX Micro series and has an available standard module slot. Confirm that your network infrastructure supports 10BASE-T or 100BASE-TX Ethernet. Check that your programming software is PL7 Pro or Unity Pro. If you need web-based diagnostics, ensure the network allows HTTP access to the module’s IP address. Consider the number of concurrent connections required; the module supports up to 64. For plants with hazardous area classifications, verify that the FM Class 1 Division 2 ratings match your environment.
