CX1020-N060 BECKHOFF CX Series Ethernet System Interface Module

Product Overview

The CX1020-N060 (CX1020N060) is a high-performance Ethernet system interface expansion designed specifically for the Beckhoff CX1020 Embedded PC series. This module provides a dedicated 10/100 Mbit/s communication port, enabling seamless vertical integration between field-level control and enterprise-level networking. Engineered for mission-critical B2B environments such as power distribution, smart manufacturing, and large-scale HVAC control, the CX1020-N060 ensures stable data throughput and low-latency connectivity. By offloading communication tasks to this modular interface, engineers can maintain high CPU performance on the primary controller while expanding the system's networking capabilities in a compact, DIN-rail mounted form factor.

Hardware Architecture and System Integration

The CX1020-N060 serves as a modular extension that connects directly to the CX1020 CPU via the internal system bus. It features a single RJ45 connection point supporting standard Cat 5 cabling. A critical architectural constraint for system designers is that this module is not combinable with the CX1100-0004 power supply unit; instead, it must be paired with other CX1100-xxxx series power supplies to ensure proper bus communication and voltage regulation.

This interface is more than a simple media converter; it is an active system component that draws power directly from the system bus, eliminating the need for external wiring for the module's logic. With its ultra-slim 19 mm width, it allows for high-density hardware configurations without compromising the thermal profile of the control cabinet.

Technical Specifications

Technical FAQs

Can I use the CX1020-N060 with a CX1100-0004 power supply?

No. The CX1020-N060 is specifically documented as incompatible with the CX1100-0004. You must use alternative power supply modules within the CX1100 range to ensure system stability and bus compatibility.

What is the maximum distance supported for the Ethernet connection?

The module supports a maximum cable length of 20 m using standard Cat 5 cabling. For distances exceeding this limit, industrial switches or signal repeaters must be integrated into the network topology.

Does this module require manual IP configuration via hardware switches?

Configuration is typically handled through the TwinCAT software environment or the operating system of the CX1020 Embedded PC, allowing for flexible DHCP or Static IP assignment based on your network architecture.

Engineering & Installation Guide

• Cable Routing and Interference: Despite the robust EMC immunity (conforming to EN 61000-6-2), always route the Ethernet Cat 5 cable away from high-current power lines and VFD output cables. Use shielded RJ45 connectors to maintain signal integrity in high-noise industrial environments.

• Bus Connection Integrity: Ensure the module is firmly snapped onto the DIN rail and that the side-mounted PC104 bus connectors are clean and free of debris before mating the module with the CX1020 CPU. A loose bus connection can cause intermittent communication "Time-Out" errors in TwinCAT.

• Thermal Clearance: Maintain the recommended installation position to allow for vertical convection. Since the module operates up to 55 Celsius, ensuring clear airflow at the top and bottom of the module prevents localized hotspots that could degrade data transfer rates.

Engineering Advantages

The CX1020-N060 is engineered for longevity in harsh environments, boasting significant vibration and shock resistance (EN 60068-2-6/27). This makes it an ideal choice for mobile automation units or machinery subjected to constant mechanical stress. Its ability to operate in 95% non-condensing humidity ensures reliability in diverse climates, from tropical manufacturing plants to refrigerated logistics centers. By utilizing the modular "N-series" interface, users gain the flexibility to scale their networking requirements without replacing the core processing unit, ensuring long-term investment protection.
