Introduction
Industrial networks stall when data cannot move fast enough between controllers and field devices. The 170INT11000 communication adapter from Schneider Electric solves that problem. As part of the Modicon Momentum automation platform, this module links your system to an Interbus Generation SUPI II network at 500 kilobits per second. It uses twisted pair cabling and a ring topology to keep data flowing reliably across the plant floor.
Technical Specifications
Speed and Protocol
The 500 kbit/s transmission rate supports responsive data exchange between master and slave devices. The Interbus Generation SUPI II protocol manages this traffic with a continuous shift register access method, so devices communicate in a predictable sequence. A CRC-16 control parameter checks every message for errors, which reduces the risk of corrupted data reaching your controller.
Connectivity and Network Scale
Two 9-pin D-Sub Interbus connectors handle the physical link. The ring topology means each device connects to the next in a closed loop, which simplifies fault isolation. You can place 0 to 254 devices on a single segment. Cable runs can exceed 3,280 feet (1,000 meters) between devices or reach 1,312.14 feet (400 meters) between two modules, giving you flexibility for large installations.
Power and Environmental Ratings
The module draws less than 200 to 400 milliamperes at 5 Volts DC and dissipates 0.8 Watt without a fiber-optic adapter. It carries an IP20 protection class, so it resists solid foreign objects but is not rated for water exposure. Operating temperature ranges from 0 to 60°C in non-condensing conditions. Storage temperature spans -40 to 85°C. The unit weighs 0.15 lb (0.07 kg), and its protective treatment is TC with CE marking.
Replacement and Upgrade Guide
When to Replace Your Adapter
If your existing Interbus adapter drops devices from the ring, throws CRC errors, or fails to hold a stable 500 kbit/s link, replacement is often faster than repair. The 170INT11000 fits Modicon Momentum racks and restores communication without a full system overhaul. Before ordering, confirm your network uses Interbus Generation SUPI II and twisted pair cabling.
Upgrade Path Considerations
This adapter suits plants already invested in Interbus infrastructure. If you plan to migrate to Ethernet-based protocols later, treat this module as a bridge that keeps production running now. The dual 9-pin D-Sub connectors match standard Interbus cabling, so you avoid rewiring costs. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Installation and Setup
Mounting and Wiring
Mount the adapter in your Momentum rack according to the platform’s standard procedure. Connect the two 9-pin D-Sub Interbus connectors to your ring cabling. Keep cable runs within the stated limits: more than 3,280 feet (1,000 meters) between devices or 1,312.14 feet (400 meters) between two modules. Maintain the ring topology by connecting every device in sequence.
Power and Environment
Supply 5 Volts DC with a current capacity that covers less than 200 to 400 milliamperes. Keep the installation area between 0 and 60°C and free of condensation. The IP20 rating means you should mount the module inside a suitable enclosure that blocks dust and moisture.
Maintenance and Reliability
Inspection Intervals
Inspect connectors and cabling every six months for looseness, corrosion, or physical damage. Check that the ring remains closed and that no device has dropped offline. Monitor for CRC-16 errors in your network diagnostics, as they often signal cable degradation or a failing connector.
Environmental Protection
Keep the cabinet temperature within the 0 to 60°C operating range. Avoid condensation, which can damage electronics even when the IP20 rating is respected. If your plant runs hot, add cabinet ventilation or cooling to protect the adapter and extend its service life.
Compatibility and Integration
The 170INT11000 works within the Modicon Momentum automation platform. It communicates over Interbus Generation SUPI II and supports master/slave arrangements with a continuous shift register access method. The ring topology and twisted pair medium match standard Interbus installations. With support for 0 to 254 devices per segment, it integrates into both small and large networks.
Selection Guide
Before buying, confirm three things: your network uses Interbus Generation SUPI II, your cabling is twisted pair, and your topology is a ring. Check that your power supply delivers 5 Volts DC at the required current. Verify the operating temperature range matches your environment. SpareTechPLC stocks genuine Schneider Electric automation parts and can help you confirm compatibility before you order.
