Introduction
In the 1980s, factory floors relied on proprietary networks that locked engineers into single-vendor ecosystems. The shift to open fieldbus standards changed everything. Schneider Electric embraced this evolution with the TSX Micro PLCs product line, delivering flexible communication options for industrial automation. The TSXPBY100 Profibus-DP option module represents that commitment, bridging Modicon Premium PLCs with one of the world’s most widely deployed industrial networks. This module lets you integrate legacy control systems into modern Profibus architectures without replacing your existing PLC infrastructure.
Why the TSXPBY100 Matters for Your Control System
The TSXPBY100 is a Profibus-DP V0 module kit designed for Schneider Electric’s Modicon Premium PLCs. It provides a physical RS485 interface using twisted shielded pairs cable and supports NRZ transmission mode. With a transmission rate spanning 9.6 Kbit/s to 12 Mbit/s, this module adapts to both long-distance and high-speed network segments. At 9.6 Kbit/s, you can achieve a segment length up to 1200 meters without a repeater. At 12 Mbit/s, the module supports 100 meters without a repeater or 400 meters with three repeaters. This flexibility makes it suitable for sprawling production lines and compact machine cells alike.

Performance You Can Rely On
The TSXPBY100 handles up to 4096 inputs and 4096 outputs, giving you comprehensive control over distributed I/O across your Profibus network. It supports up to 124 slaves when repeaters extend the bus. The module operates as both a class 1 and class 2 master. Class 1 functions include reading and writing DP slave I/O data, setting slave parameters on power up, checking slave configuration, and transferring diagnostic data. Class 2 master services cover global control and master diagnostic requests. Note that Profibus FMS message handling is not supported. This module draws 400 mA at 5 V DC from the rack power supply, so verify your rack has adequate capacity before installation.
Built for Demanding Industrial Environments
Schneider Electric engineered the TSXPBY100 to withstand harsh conditions. It complies with IEC 68-2-6 for vibration immunity, IEC 68-2-27 for shock immunity, and IEC 1000-4-2 for electrostatic discharge immunity. The operating temperature range of 0 °C to +60 °C suits most climate-controlled industrial settings. Storage tolerance extends from -25 °C to +70 °C. Humidity can range from 30% to 95% non-condensing, and the module operates at altitudes up to 2000 meters. These ratings ensure reliable performance in factories, processing plants, and remote installations.
Installation and Setup
The TSXPBY100 kit includes a host module for the PCMCIA card, a T-junction box for tapping the main bus, and a Profibus DP PCMCIA card with an integrated 0.6 m connecting cable. Install the host module in your Modicon Premium PLC rack, then insert the PCMCIA card. Use the T-junction box to connect to the Profibus network via twisted shielded pairs cable. Ensure the rack power supply provides 5 V DC at sufficient current. Verify that your network termination and grounding follow Profibus standards. Before powering up, confirm all connections are secure and the module is properly seated.
Compatibility and Integration
The TSXPBY100 works with Modicon Premium PLCs and Atrium slot-PLCs. It communicates over Profibus-DP using RS485 physical interface. The module supports master class 1 and master class 2 access methods. It handles check slave configuration on power up, manage monitoring requests, read/write DP slave I/O data, set slave parameters, and transfer slave diagnostic data. No master/master dialogue is supported for class 2 master. Profibus FMS message handling is not supported. This module integrates seamlessly into existing Profibus networks, allowing you to add Schneider control to mixed-vendor environments.
Selection Guide
Before purchasing the TSXPBY100, verify your PLC model supports this option module. Check that your rack power supply can deliver 400 mA at 5 V DC. Confirm your network speed and distance requirements match the module’s capabilities. If you need to cover long distances, plan for repeaters to extend segment length and slave count. The kit includes the host module, T-junction box, and PCMCIA card with cable. For availability and replacement options, contact SpareTechPLC. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
