Introduction to the 170ENT11002 Communication Adapter
From a maintenance engineer’s perspective, network reliability starts with the adapter. The 170ENT11002 is a communication adapter from Schneider Electric’s Modicon Momentum series. It connects controllers and devices over an Ethernet TCP/IP network using a 100BASE-TX port. This unit supports master/slave and peer-to-peer access methods, making it a practical choice for both established and emerging network environments.
Technical Specifications That Matter
The 170ENT11002 operates at a transmission rate of 10 Mbit/s. It uses an RJ45 connector for 10BASE-T and supports shielded twisted pairs cable. The adapter handles up to 32 devices per segment. Network topology options include star and multi-drop configurations. With a repeater, cable distance can exceed 3,280 feet (1,000 meters); without a repeater, it stays under that limit. The IP20 protection class guards against solid objects larger than 12 mm. The unit functions in ambient temperatures from 0 to 60°C and stores safely from -40 to 85°C, both in non-condensing environments.
Where the 170ENT11002 Fits
This adapter suits factory floors, process control rooms, and remote I/O cabinets. In a packaging line, it links a Momentum controller to a supervisory system over Ethernet TCP/IP. In a water treatment plant, it supports peer-to-peer communication between segments. The star topology simplifies troubleshooting, while multi-drop reduces cabling in dense panels. The 10 Mbit/s rate matches legacy 10BASE-T networks, so you can integrate without a full overhaul.
Installation and Setup
Mount the adapter in a clean, dry enclosure. Use shielded twisted pairs cable and an RJ45 connector for 10BASE-T. Assign IP parameters via a BOOTP server or manually set a unique IEEE global address. Keep the segment device count at or below 32. For distances over 3,280 feet (1,000 meters), add a repeater. Maintain ambient temperature between 0 and 60°C and avoid condensation. The fail-safe state helps protect network integrity during faults.
Maintenance and Reliability
Inspect the RJ45 connector and cable shielding every six months. Check for dust buildup, since IP20 does not seal against water. Verify that ambient temperature stays within 0 to 60°C. Monitor the CRC-32 control parameter for transmission errors. A stable, non-condensing environment extends service life. Because the adapter supports up to 32 devices per segment, plan spare capacity to simplify future expansion.
Compatibility and Integration
The 170ENT11002 works within the Modicon Momentum automation platform. It communicates over Ethernet TCP/IP and supports BOOTP server configuration. The 10BASE-T port and RJ45 connector match standard industrial cabling. Star and multi-drop topologies allow flexible integration with existing controllers and I/O. The adapter also supports peer-to-peer and master/slave access, so it fits both centralized and distributed architectures.
Selection Guide
Before ordering, confirm your network uses Ethernet TCP/IP and 10BASE-T. Check that your segment stays within 32 devices. Verify cable distance needs and whether a repeater is required. Ensure the enclosure maintains 0 to 60°C and stays non-condensing. The 170ENT11002 carries the CE marking and TC protective treatment. For availability and replacement options, contact SpareTechPLC. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
