Why the 170ENT11002 Belongs in Your Modicon Momentum System
When your control cabinet already runs a Modicon Momentum platform, adding a reliable Ethernet communication adapter should not force a full architecture change. The 170ENT11002 from Schneider Electric solves exactly that problem. It is a communication adapter for the Modicon Momentum automation platform, built to connect your existing I/O and controllers to an Ethernet TCP/IP network. As an engineer, you want a module that drops into your current design, speaks the protocol your plant already uses, and keeps data moving without surprises. This adapter does that with a 100BASE-TX port, master/slave and peer-to-peer access, and a compact form factor.
Key Technical Parameters That Matter on the Plant Floor
Ethernet TCP/IP Communication
The 170ENT11002 uses Ethernet Transmission Control Protocol/Internet Protocol as its communication protocol. That means it fits networks built around standard Ethernet infrastructure, not a proprietary bus. The unit provides a 100BASE-TX Ethernet port and an RJ45 connector for 10BASE-T. It supports a transmission rate of 10 Mbit/s and a baud rate of 10 megabits per second. For many industrial control tasks, that rate is more than enough for cyclic data exchange and diagnostics.
Access Methods and Network Topology
This adapter supports master/slave access and peer-to-peer (P2P) communication. You can place it in a star network or a multi-drop topology. Each segment can handle 0 to 32 devices, which gives you room to grow without immediately adding another segment. The control parameter is CRC-32, a checksum method that helps detect transmission errors in the data frame.
Environmental and Physical Ratings
The module carries an IP20 protection class. It is safeguarded against solid objects larger than 12 mm but is not rated for water protection. Keep it inside a clean, controlled enclosure. The ambient operating temperature range is 0 to 60°C in a non-condensing environment. Storage temperature extends from -40 to 85°C, also non-condensing. Operating altitude is less than 16,404 feet (5,000 meters). The net weight is 0.15 lb (0.07 kg), so it adds almost no mechanical load to a DIN rail or mounting plate.
Cable Distance and Repeater Use
You can run more than 3,280 feet (1,000 meters) between devices when you use a repeater. Without a repeater, the maximum cable distance is less than 3,280 feet (1,000 meters). Plan your segment lengths accordingly, especially in long conveyor or process lines.
Where the 170ENT11002 Fits in Real Applications
Replacement and Upgrade Path
Angle D applies here. If you are maintaining an existing Modicon Momentum installation, the 170ENT11002 is a direct communication adapter for that platform. You do not need to redesign the network or switch to a different I/O family. The module configuration uses a BOOTP server to assign IP parameters, and the IP address is user assigned. A unique IEEE global address is also part of the addressing scheme. This makes replacement straightforward when you follow your site’s network plan.
Material Handling and Assembly Lines
In a multi-drop topology, this adapter can link up to 32 devices per segment. That suits assembly lines where multiple stations report to a central controller. The star network option works well when you want dedicated links from a switch to each adapter. The 10 Mbit/s transmission rate supports the cyclic data typical of discrete manufacturing.
Process Skids and Remote Panels
With a cable distance of up to 1,000 meters using a repeater, you can connect remote skids or field panels back to the main control room. The IP20 rating means the adapter belongs inside a protected enclosure, not in a washdown area. The 0 to 60°C operating range covers most climate-controlled industrial rooms.
Installation and Setup Guidance
Mount the 170ENT11002 inside a suitable enclosure that maintains the IP20 environment. Use shielded twisted pairs cable as the transmission support medium. Connect the RJ45 connector for 10BASE-T to your network. Assign IP parameters through the BOOTP server method described in the module configuration. Confirm that your segment does not exceed 32 devices. If you need to span more than 1,000 meters, insert a repeater. Keep the ambient temperature within 0 to 60°C and avoid condensation. The fail state is fail safe, so verify how your system reacts during a communication loss.
Maintenance and Reliability
Inspect the adapter periodically for loose connections and dust buildup inside the enclosure. Because the unit has no moving parts, wear is minimal. The main risks are environmental: condensation, excessive heat, and cable damage. Keep the cabinet sealed and within the specified temperature range. If you use a repeater, check its power and link status during routine rounds. A stable Ethernet TCP/IP link depends on good cabling and clean power as much as on the adapter itself.
Compatibility and Integration
The 170ENT11002 belongs to the Modicon Momentum automation platform. It communicates over Ethernet TCP/IP and supports master/slave and peer-to-peer access. The module configuration uses a BOOTP server to assign IP parameters, and the IP address is user assigned. It works in star and multi-drop topologies with shielded twisted pairs cable. The RJ45 connector for 10BASE-T and the 100BASE-TX port let you integrate with standard Ethernet switching equipment. The adapter carries the CE marking and TC protective treatment. It does not support Modbus or EtherNet/IP based on the available data, so confirm your protocol requirements before ordering.
Selection Checklist Before You Buy
Verify that your network uses Ethernet TCP/IP. Confirm that your segment device count stays within 0 to 32. Check that your cable distance is under 1,000 meters without a repeater, or plan for a repeater if you need more. Ensure your enclosure maintains IP20 conditions and that ambient temperature stays between 0 and 60°C. Confirm you can assign IP parameters through a BOOTP server.
