Product Introduction
When your industrial network demands reliable, high-speed communication between multiple devices, the Schneider 170INT11003 Communication Adapter provides a robust solution. Part of the Modicon Momentum series, this adapter uses a Master/Slave access method combined with a Continuous Shift Register to ensure seamless data transfer across your automation system. Supporting the Interbus Generation SUPI III protocol, it handles up to 254 devices per segment, making it ideal for expanding control networks.
Technical Specifications Breakdown
Key specifications of the 170INT11003 include:
- Communication Protocol: Interbus Generation SUPI III ensures deterministic data exchange.
- Transmission Rate: 500 kilobits per second for fast data handling.
- Network Topology: Ring network configuration enhances reliability and simplifies cabling.
- Maximum Cable Distance: More than 3,280 feet (1,000 meters) between devices, or 1,312.14 feet (400 meters) between two modules, allowing flexible placement.
- Power Dissipation: Only 0.8 Watt (without fiber-optic adapter) for energy-efficient operation.
- Protection Class: IP20 for basic protection against solid objects.
- Ambient Operating Temperature: 0 to 60°C in non-condensing environments, suitable for typical industrial settings.
- Electrical Connection: Two 9-pin D-Sub Interbus connectors for secure wiring.
- Control Parameter: CRC-16 for data integrity verification.
- Transmission Cable: Twisted pairs cable reduces electromagnetic interference.
Industry Applications
This communication adapter excels in manufacturing lines where multiple sensors, actuators, and controllers need synchronized operation. For example, in a packaging plant, the 170INT11003 connects up to 254 devices per segment, enabling real-time coordination of conveyors, labelers, and sealers. Its ring topology provides fault tolerance—if one cable breaks, the network continues operating, minimizing downtime. In material handling systems, the long cable distance support (over 3,280 feet) allows central controllers to communicate with remote stations without repeaters.
Installation & Setup Guidance
Mount the adapter in a clean, dry enclosure with adequate ventilation to maintain ambient temperatures between 0 and 60°C. Use the two 9-pin D-Sub connectors to daisy-chain devices in a ring topology. Ensure twisted pairs cable is properly shielded and grounded to maximize electromagnetic compatibility. Configure the master/slave addressing for each device (0 to 254 per segment) using the Interbus Generation SUPI III protocol. Verify CRC-16 checksums during commissioning to confirm data integrity.
Maintenance & Reliability
Periodically inspect the D-Sub connectors for corrosion or loose connections, as these can cause intermittent communication faults. Keep the IP20-rated enclosure free from dust and debris. The low power dissipation (0.8 Watt) reduces heat buildup, extending component life. For long-term reliability, store the adapter in non-condensing conditions between -40 and 85°C when not in use. If the network experiences errors, check the CRC-16 parameter settings and cable integrity.
Compatibility & Integration
The 170INT11003 integrates seamlessly with other Modicon Momentum devices and any controller supporting Interbus Generation SUPI III protocol. Its master/slave access method and continuous shift register work with PLCs, drives, and I/O modules in a ring topology. The twisted pairs cable requirement aligns with standard industrial wiring practices, simplifying installation in existing plants.
Buying Guide & Purchasing Advice
Before purchasing, verify that your existing system supports Interbus Generation SUPI III protocol and ring topology. Confirm the number of devices per segment (up to 254) and cable distance requirements (over 3,280 feet between devices). The adapter weighs only 1.00 lbs (0.45 kg), making it easy to handle and mount.
