Schneider Electric Modicon Premium TSXSCY11601 RS485 Communication Module – 32 Devices, 1300 m

The TSXSCY11601 links Modicon Premium controllers to industrial RS485 buses. It manages up to 32 devices across a 1300 m network. The module runs Modbus, Uni-Telway, and character mode frames. Engineers choose the TSXSCY11601 for its isolated serial link and rich diagnostic counters.

Installation Guide

• Insert the module into a free Premium or Atrium rack slot.
• Connect the SUB-D 25 port to the RS485 bus using two twisted shielded pairs.
• Keep each tap link at or under 15 m to protect signal quality.
• Terminate the bus ends per RS485 rules to avoid reflections.
• Assign slave addresses in the 0–247 range before power-up.
• Set the baud rate between 1.2 and 19.2 kbit/s to match the network.
• Check the green RUN LED and CH0 activity after start-up.
• Read the ERR LED and diagnostic counters when faults appear.
• Configure the module in Unity Pro before downloading the project.

Frequently Asked Questions

• How many devices can the TSXSCY11601 handle? It supports 32 devices with addresses from 0 to 247 on one bus.
• What is the longest bus length? The module reaches 1300 m in Uni-Telway, Modbus, and character mode.
• Which baud rates does the module support? It runs from 1.2 kbit/s up to 19.2 kbit/s in asynchronous baseband mode.
• How does the module check data integrity? It applies one CRC 16 check to every frame it sends or receives.
• What do the three LEDs mean? RUN shows normal operation, ERR flags module faults, and CH0 shows link activity.
