Schneider 170DNT11000 Profibus DP Adapter

Product Introduction

The Schneider Electric 170DNT11000 is a robust communication adaptor engineered for the Modicon Momentum automation platform. This module leverages the widely adopted Profibus DP protocol, delivering flexible transmission speeds from 9.6 to 12 Mbit/s over twisted-pair cabling. It supports both multidrop and ring topologies, accommodating up to 126 devices per network. With switch-selectable addressing and CRC-16 error checking, this adaptor ensures reliable and straightforward integration. Its IP20-rated housing and broad environmental tolerances make it a dependable choice for factory floor applications.

Technical Specifications

The 170DNT11000 communication adaptor offers outstanding performance for Profibus DP networks. It transmits data at user-selectable rates ranging from 9.6 Kbit/s up to 12 Mbit/s, allowing you to optimize speed based on your cable length and network requirements. This module supports up to 126 devices on a single network segment, which makes it ideal for large-scale distributed I/O systems. It employs CRC-16 control parameters for robust error detection, ensuring data integrity throughout transmission. A single 9-pin SUB-D connector provides the physical electrical interface, while switch-selectable addressing simplifies network configuration and device identification.

Topology and Cabling Flexibility

The 170DNT11000 adaptor gives you considerable flexibility in network design. You can deploy it in either a multidrop (daisy-chain) or ring topology, depending on your system's redundancy and layout requirements. The module supports a maximum cable length of 1200 meters per segment at lower baud rates, providing ample reach for large facilities. For optimal performance, you should use standard shielded twisted-pair Profibus cables and observe proper termination practices at both ends of the bus. This flexibility allows the 170DNT11000 to fit seamlessly into both new installations and legacy system upgrades.

Mechanical & Environmental Parameters

The 170DNT11000 features an IP20-rated housing, which protects the internal electronics from solid objects larger than 12.5 mm. This module operates reliably across a wide temperature range of 0°C to 60°C, making it suitable for most indoor industrial environments. For storage, it tolerates extreme conditions from -40°C to 85°C, allowing safe long-term warehousing. Additionally, the device withstands a relative humidity of up to 95% without condensation, ensuring stable performance in humid conditions. UL and CSA certifications confirm that this adaptor meets stringent North American safety and quality standards.

Installation and Setup Guide

Installing the 170DNT11000 communication adaptor is a straightforward process. You simply mount the module onto a Modicon Momentum I/O base, and it draws its operating power directly from that base. Next, you connect your Profibus DP network cable to the 9-pin SUB-D connector on the front panel. You must then set the node address using the switch-selectable addressing mechanism, ensuring each device on the bus has a unique address. Remember to activate bus termination resistors at both physical ends of the Profibus segment to prevent signal reflections. After powering up, the module will automatically negotiate communication parameters with the Profibus master.

Frequently Asked Questions (FAQ)

1. What protocol does the 170DNT11000 use for communication?
The Schneider Electric 170DNT11000 uses the Profibus DP (Decentralized Periphery) protocol. This industry-standard fieldbus enables high-speed cyclic data exchange between a PLC master and distributed I/O devices.

2. How many devices can I connect using the 170DNT11000?
This adaptor supports up to 126 devices on a single Profibus DP network segment. For larger systems, you can use repeaters to extend the network and add more devices.

3. What is the maximum cable length for the 170DNT11000?
The 170DNT11000 supports a maximum cable length of 1200 meters per segment. However, you must use lower transmission rates (such as 9.6 Kbit/s) to achieve this maximum distance. Higher speeds like 12 Mbit/s require shorter cable runs.

4. What kind of cable should I use with the 170DNT11000?
You should use a standard shielded twisted-pair Profibus cable, typically with a characteristic impedance of 150 ohms. Proper shielding and correct grounding are essential for reliable communication at higher speeds.

5. Does the 170DNT11000 require a separate power supply?
No. The 170DNT11000 receives its operating power directly from the Modicon Momentum I/O base to which you attach it. This design eliminates the need for external power wiring and simplifies your overall installation.
