Schneider 171CBU98090 Modicon Momentum Automation Platform PLC

Product Overview

When extensive I/O capacity and robust communication are required, the Schneider 171CBU98090 automation platform delivers. Part of the Modicon Momentum series, this PLC handles 2048 inputs and 2048 outputs, making it suitable for large-scale industrial processes. Its compact design and versatile connectivity simplify system integration.

Technical Specifications

The 171CBU98090 operates with a clock frequency of 333 MHz and provides 3584 kB of program memory. It supports Modbus and Modbus TCP protocols, with addressing from 1 to 247 Modbus and a unique IEEE global address for Modbus TCP. The unit features RS232/485, Ethernet, and USB communication ports. It mounts on a 35 mm symmetrical DIN rail and is IP20 rated. Certifications include CE, FM, C-Tick, UL 508, CSA C22.2 No 142, and EN/IEC 61131-2. Supply voltage is 4.75-5.25 V. Weight is 2.06 lbs (0.94 kg).

Industry Applications

This platform excels in material handling, packaging, and water treatment systems where high I/O counts and deterministic control are critical. For example, in a bottling line, the 171CBU98090 coordinates multiple conveyors and fillers via Modbus TCP, reducing wiring complexity. Its 2048 I/O capacity supports future expansion without controller replacement.

Installation & Setup

Mount the 171CBU98090 on a 35 mm DIN rail in a clean, dry enclosure. Connect the supply voltage (4.75-5.25 V) using a regulated power source. Use the RS232/485 port for initial configuration and the Ethernet port for network integration. Verify Modbus addressing (1-247) before commissioning. The unit supports Modicon STB I/O for distributed I/O expansion.

Maintenance & Reliability

Periodically inspect the DIN rail mounting and ensure the IP20 enclosure remains sealed. Check communication cable connections for wear. The 171CBU98090's solid-state design minimizes moving parts, reducing maintenance intervals. Regular firmware updates via the USB port help maintain system security and performance.

Compatibility & Integration

The 171CBU98090 integrates seamlessly with Modicon STB I/O modules and supports multidrop Modbus and star Modbus TCP topologies. It communicates with HMIs, drives, and sensors using Modbus or Modbus TCP. The unique IEEE global address simplifies network identification in large plants.
