170LNT71000 | Schneider DeviceNet Adapter 500 kbit/s

Introduction to the 170LNT71000

When your automation network demands reliable DeviceNet communication, the 170LNT71000 from Schneider Electric delivers. This communication adapter belongs to the Modicon Momentum series, engineered for multi-drop trunk topologies. It supports 0 to 64 devices per segment, making it a flexible choice for various industrial setups.

With transmission rates of 125, 250, and 500 kilobits per second, the 170LNT71000 adapts to your network speed requirements. Its compact design and IP20 protection ensure easy integration into control cabinets.

Key Features and Technical Specifications

The 170LNT71000 offers several standout features that enhance network performance:

• Transmission rates of 125, 250, and 500 kbit/s for versatile network configurations.
• Multi-drop trunk topology supports up to 64 devices per segment.
• Twisted pair cable media for reliable signal integrity.
• Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) access method.
• Master/Slave and peer-to-peer (P2P) communication modes.
• CRC-16 error checking ensures data integrity.
• Operating temperature range from 0 to 60°C in non-condensing environments.
• Storage temperature from -40 to 85°C for robust handling.
• IP20 protection class for indoor use.

One distinctive spec is the maximum cable distance between devices, which can exceed 1,640.4 feet (500 meters) depending on the transmission rate. This allows for expansive network layouts without signal degradation.

Applications and Use Cases

The 170LNT71000 is ideal for factory automation, material handling, and process control systems. Its multi-drop capability enables efficient communication among sensors, actuators, and controllers. For example, in a packaging line, the adapter coordinates multiple devices, improving throughput. Additionally, its peer-to-peer mode supports direct device-to-device communication, reducing latency in critical applications.

Installation and Setup

Installing the 170LNT71000 is straightforward. The single 5-pin DeviceNet connector simplifies wiring. Ensure the network is terminated correctly and devices are within the 500-meter cable distance limit. Verify that the operating environment stays within the specified temperature and altitude ranges (below 16,404 feet or 5,000 meters). Always follow the manufacturer's manual for detailed installation instructions.

Maintenance and Reliability

Regular inspection of the adapter and its connections helps maintain reliable operation. Check for loose connectors and signs of wear on the twisted pair cable. The IP20 rating means it should be housed in a clean, dry enclosure. Periodic verification of network communication can prevent unexpected downtime. For any issues, consult the official Schneider documentation or contact Petro Auto Tech for support.

Compatibility and Integration

The 170LNT71000 is designed for the Modicon Momentum platform, ensuring seamless integration with Schneider Electric's automation systems. It supports the DeviceNet protocol, which is widely used in industrial networks. The adapter works with master/slave and peer-to-peer configurations, offering flexibility in system design. Its multi-drop topology allows connection of up to 64 devices, making it suitable for both small and large installations.

Comparison with Similar Adapters

Compared to other DeviceNet adapters, the 170LNT71000 stands out due to its support for three transmission rates and a large device count per segment. Many adapters only offer a single speed, limiting network design options. The 500-meter maximum cable distance is also above average, enabling longer trunk lines. Additionally, the CSMA/CA access method reduces collision risks, enhancing data reliability.
