Introduction
When a manufacturing line demands reliable, real-time data exchange between controllers and supervisory systems, the Schneider 170ENT11002 Communication Adapter provides a proven solution. This Modicon Momentum series module bridges the gap between field devices and the enterprise network, ensuring seamless information flow in demanding industrial environments.
Technical Specifications Breakdown
The 170ENT11002 operates on Ethernet Transmission Control Protocol/Internet Protocol (TCP/IP) at a baud rate of 10 megabits per second. Its 100BASE-TX port supports both master/slave and peer-to-peer (P2P) access methods, offering flexibility for various control architectures. The unit uses CRC-32 for error checking, ensuring data integrity across the network.
With an IP20 protection class, the adapter is protected against solid objects larger than 12 mm, making it suitable for clean, controlled environments. It operates reliably in ambient temperatures from 0 to 60°C and can be stored in temperatures ranging from -40 to 85°C, both in non-condensing conditions. The device functions at altitudes up to 16,404 feet (5,000 meters).
Network topology options include star and multi-drop configurations. The adapter supports up to 32 devices per segment via an RJ45 connector for 10BASE-T. Maximum cable distance between devices exceeds 3,280 feet (1,000 meters) with a repeater, and remains under that threshold without one.
Industry Applications
In a typical automotive assembly line, the 170ENT11002 connects programmable logic controllers (PLCs) to a central monitoring system. Its peer-to-peer capability allows direct communication between workstations, reducing latency and improving coordination. The star topology simplifies troubleshooting—if one device fails, the rest of the network remains operational.
For a water treatment facility, the adapter's master/slave access method enables a single controller to poll multiple remote I/O racks. The 10 Mbit/s baud rate is sufficient for process data, while the CRC-32 error control ensures that sensor readings are transmitted accurately over long cable runs.
Installation & Setup Guidance
Mount the 170ENT11002 on a standard DIN rail within an IP20-rated enclosure. Connect the RJ45 port to a 10BASE-T network using shielded twisted-pair cable. For multi-drop topologies, ensure proper termination at both ends of the segment. Use the BOOTP server to assign IP parameters, or configure a unique IEEE global address manually. The module's fail-safe state will maintain outputs in a predefined condition if communication is lost.
Maintenance & Reliability
Periodically inspect the RJ45 connector for dust or corrosion, especially in environments with high humidity. Verify that the ambient temperature stays within 0 to 60°C to prevent overheating. The adapter's solid-state design requires no routine calibration, but checking network cable integrity every six months can prevent intermittent faults. The IP20 rating means the unit should not be exposed to water or heavy dust—keep the enclosure sealed.
Compatibility & Integration
The 170ENT11002 is part of the Modicon Momentum automation platform and communicates via Ethernet TCP/IP. It integrates seamlessly with Schneider Electric controllers and other devices that support this protocol. The adapter works in both star and multi-drop topologies, making it compatible with existing network infrastructure. For systems requiring peer-to-peer data exchange, the P2P access method eliminates the need for a dedicated master controller.
Selection Guide & Purchasing Advice
Before ordering, verify that your network uses 10BASE-T or 100BASE-TX standards. The 170ENT11002 is not suitable for 1000BASE-T (Gigabit) networks without a media converter. Ensure that the total number of devices per segment does not exceed 32. For cable runs longer than 3,280 feet, plan to install repeaters. SpareTechPLC stocks this adapter and can confirm current lifecycle status and availability.
Frequently Asked Questions
Q: Can the 170ENT11002 be used with a 1000BASE-T switch?
A: Yes, but the adapter will operate at 10 Mbit/s. It is not compatible with 1000BASE-T signaling; the switch must support 10BASE-T or 100BASE-TX auto-negotiation.
Q: What is the maximum number of devices I can connect in a multi-drop topology?
A: The adapter supports 0 to 32 devices per segment. Exceeding this limit may cause signal degradation.
Q: Does the 170ENT11002 support DHCP for IP address assignment?
A: No. It uses a BOOTP server to assign IP parameters, or you can assign a user-defined IP address.
Q: What type of cable is recommended for the RJ45 connection?
A: Shielded twisted-pair (STP) cable is recommended to minimize electromagnetic interference in industrial environments.
Q: Is the 170ENT11002 suitable for outdoor use?
A: No. Its IP20 protection class does not provide water or dust ingress protection, so it must be installed in a clean, dry enclosure.
