SCHNEIDER ELECTRIC TSXSCY11601 Product Description

Overview

SCHNEIDER ELECTRIC TSXSCY11601 is a Modicon Premium RS485 communication module for Schneider Electric Premium or Atrium PLC automation platforms. The module provides one serial RS485 communication link for Modbus and Uni-Telway networks, allowing the PLC to communicate with drives, controllers, HMI devices, remote I/O, instruments and other Modbus or Uni-Telway slaves or masters. It is a discontinued service-only Premium communication spare used in existing Modicon Premium control installations.

Features

The TSXSCY11601 integrates one serial link with one SUB-D 25 connector. The communication port is isolated RS485 and supports asynchronous baseband transmission. Supported transmission frames include RTU/ASCII, character mode and Uni-Telway. The module supports Modbus communication and Uni-Telway bus operation in a master or slave access arrangement according to the system configuration.

Transmission rate is 1.2 to 19.2 kbit/s. The network supports up to 32 devices on two twisted shielded pairs. Address range is 0 to 247. Bus length is up to 1300 m for character mode, Modbus and Uni-Telway references, with maximum tap link length 15 m. Each request supports 120 words or 1920 bits, and each frame uses one CRC 16 control parameter. Monitoring functions include diagnostic counters and event counters.

The module has three local status indicators: one CH0 LED for communication, one ERR LED for internal fault or module failure, and one RUN LED for module operating state. Current consumption is 350 mA at 5 V DC. Module format is standard, and net weight is 0.34 kg or 0.75 lb. Operating ambient temperature is 0 to 60 degrees Celsius, storage temperature is -25 to 70 degrees Celsius, relative humidity is 5 to 95 percent without condensation, and operating altitude is up to 2000 m.

Principle

The TSXSCY11601 communication module mounts in a Modicon Premium or Atrium PLC rack and provides the serial RS485 physical layer for network communication. The PLC application exchanges data with connected devices through the module’s serial link. Modbus RTU or ASCII frames and Uni-Telway frames are transmitted over the shielded twisted-pair RS485 bus to read or write registers, bits, input values, output values or device status according to the supported communication functions.

The module handles physical signal conversion, bus addressing, frame checking and communication diagnostics. LEDs indicate link activity, module operation and fault condition. Diagnostic and event counters support communication troubleshooting. The module depends on the host PLC, rack backplane, power supply, communication parameters, bus cable, termination and controller configuration to establish communication with the connected devices.

Replacement should verify the host PLC model, rack or slot position, module compatibility, serial protocol, baud rate, station address, RS485 cable and termination, SUB-D 25 wiring, Modbus or Uni-Telway device list, communication parameter backup and Unity Pro or controller configuration. Because the module is discontinued, the replacement should be checked for compatibility with the existing Premium or Atrium system before commissioning.

Applications

SCHNEIDER ELECTRIC TSXSCY11601 is used in legacy Modicon Premium PLC systems for serial Modbus or Uni-Telway communication with variable-speed drives, servo drives, remote I/O blocks, HMIs, operator panels, temperature controllers, pressure or flow instruments, metering devices, PLC-to-PLC links and other serial industrial devices. Applications include packaging machinery, material handling, production lines, machine tools, process equipment, HVAC control, water and wastewater, utilities and general industrial automation. In existing Premium or Atrium systems, the module serves as a direct replacement communication spare when the protocol, address, cable connection, rack slot and controller configuration match the original installation.
