Product Overview
When a Momentum PLC drops off the network, production stops. The 170ENT11000 from Schneider Electric restores dependable Ethernet TCP/IP connectivity for Modicon Momentum systems. This adapter handles 10/100 Mbps data transfer and supports peer-to-peer and master/slave communication modes. Maintenance teams value its clear LED indicators and automatic fail-safe response, which simplify troubleshooting and protect processes during network faults.
Technical Specifications
Data Transfer Speed
The 170ENT11000 supports 10 Mbps and 100 Mbps Ethernet, automatically matching network capability. This flexibility lets you integrate legacy 10 Mbps segments with modern 100 Mbps infrastructure without hardware changes.
Network Capacity
Up to 32 devices can share a single segment, and cable runs may extend to 1000 meters. These limits suit large facilities where controllers, drives, and I/O reside far apart. Plan segment lengths carefully to stay within the 1000-meter maximum.
Error Detection and Safety
CRC-32 verification catches corrupted frames before they disrupt control. If the network fails, the adapter triggers an automatic fail-safe response, helping maintain safe system states. These features reduce unplanned downtime and simplify fault diagnosis.
Physical and Connection Details
The adapter weighs 0.25 lbs (0.11 kg) and uses an RJ45 port for 100BASE-TX connections. Shielded twisted pair wiring is the required transmission medium, supporting star and multidrop network structures.
Reliability in Industrial Networks
From a maintenance engineer’s view, the 170ENT11000 earns its place through predictable behavior. LED signals for link speed, activity, and system status let you verify health at a glance. CRC-32 error detection flags data integrity issues early, while the automatic fail-safe response prevents unsafe conditions during network loss. The 0.11 kg housing mounts easily inside existing panels, and the RJ45 port accepts standard 100BASE-TX cabling. For plants running Modicon Momentum, this adapter minimizes service time and keeps lines running.
Replacement and Upgrade Guide
If you are replacing a failed Momentum Ethernet adapter, the 170ENT11000 is a direct fit for the series. Verify your network uses Ethernet TCP/IP and shielded twisted pair wiring. Check that your segment stays within 32 devices and 1000 meters. The adapter’s unique IEEE-assigned address and configurable IP address simplify drop-in replacement. Before ordering, confirm your existing cable type and network structure (star or multidrop). SpareTechPLC stocks this adapter and can help you verify compatibility.
Installation and Setup
Mount the adapter in a dry, vibration-free location. Connect the RJ45 port to a 100BASE-TX network using shielded twisted pair cable. Configure the IP address according to your network plan. Use the LED indicators to confirm link speed and activity. No special tools are required, but follow your site’s safety procedures during installation.
Maintenance and Troubleshooting
Inspect the adapter periodically for loose connections and dust buildup. Check LED status to confirm link speed and activity. If the network link fails, verify cable integrity and segment length. CRC-32 errors may indicate electrical noise; review cable routing and shielding. The automatic fail-safe response activates on network loss, so investigate root causes before resetting. Keep spare units on hand to reduce mean time to repair.
Compatibility and Integration
The 170ENT11000 integrates with Modicon Momentum controllers and other Ethernet TCP/IP devices. It supports star and multidrop topologies, making it suitable for both centralized and distributed layouts. The RJ45 port ensures standard connectivity with switches and hubs. Up to 32 devices per segment allow flexible network design.
