Introduction to EMEROSN NTE207-CBNS-0000
Product Description
The EMEROSN NTE207-CBNS-0000 is a rugged, industrial-grade network communication module designed for reliable data transmission and protocol conversion in harsh automation environments. As a key model in EMEROSN’s NTE (Network Transmission Equipment) series—specialized for industrial connectivity—it excels at bridging diverse network architectures, extending communication distances, and ensuring data integrity in applications where downtime or data loss is costly. This module is ideal for industries such as petrochemical processing, power generation, water/wastewater treatment, and discrete manufacturing, where seamless integration of legacy and modern systems (e.g., PLCs, HMIs, SCADA servers) is critical.
The model designation “NTE207-CBNS-0000” encodes key attributes: “NTE207” denotes the product series (7th-gen industrial communication modules), “CBNS” specifies core functionality (Control network integration, Bidirectional protocol conversion, Network redundancy, Security features), and “0000” references standard configuration (no optional add-ons, default firmware). Unlike commercial network switches or converters, the NTE207-CBNS-0000 is engineered to withstand extreme conditions—including wide temperature ranges, high vibration, and electromagnetic interference (EMI)—while supporting critical industrial protocols and redundant communication paths. Its compact form factor and DIN-rail mounting design save cabinet space, and its rugged aluminum housing ensures long-term reliability in dusty, humid, or chemically exposed environments.
Typical use cases include:
- Converting Modbus RTU (RS485) signals from legacy sensors to Ethernet/IP for integration with modern SCADA systems.
- Extending PROFINET IRT networks over long distances (up to 10km) using fiber-optic or Ethernet copper links in large factories.
- Providing network redundancy (e.g., ring topology) for critical control loops in power plants, ensuring communication continuity if a single link fails.
- Securing data transmission between distributed control systems (DCS) and cloud platforms via built-in encryption (e.g., TLS 1.3) to prevent unauthorized access.

System Overview
The EMEROSN NTE207-CBNS-0000 operates as a central connectivity hub in industrial automation systems, integrating five core functional layers to ensure reliable, secure, and flexible data transmission:
1. Protocol Translation Layer
This layer acts as a “universal translator” between legacy and modern systems, eliminating the need to replace expensive older equipment. For example, in a petrochemical plant with 20-year-old Modbus RTU pressure sensors, the NTE207-CBNS-0000 converts sensor data to Ethernet/IP, allowing integration with a new Allen-Bradley ControlLogix PLC. The module’s bidirectional conversion ensures the PLC can also send configuration commands to the sensors (e.g., adjusting measurement ranges), preserving two-way communication.
2. Network Extension Layer
The module extends network coverage beyond standard Ethernet limits. Using SFP fiber-optic modules, it can transmit PROFINET IRT signals up to 20km—critical for large facilities like power plants or mining sites where equipment is spread across vast areas. For copper-based extensions, it supports Ethernet over twisted-pair cables up to 100m (per IEEE 802.3) and includes signal amplification to maintain data integrity over long runs.
3. Redundancy & Resilience Layer
To minimize downtime, the NTE207-CBNS-0000 supports ring network topologies (e.g., MRP) with ≤50ms recovery time. In a water treatment plant, for instance, if a single Ethernet cable in the ring is cut, the module automatically reroutes data through an alternate path—ensuring continuous communication between the DCS and pump control systems. Dual power inputs further enhance resilience: if the primary 24V DC supply fails, the module switches to the backup supply (e.g., a battery) without interruption.
4. Security Layer
Industrial networks are increasingly vulnerable to cyberattacks, so the module includes robust security features. It encrypts all data in transit (TLS 1.3 for Ethernet, AES-256 for serial) to prevent eavesdropping, and role-based access control restricts configuration changes to authorized personnel. For cloud-connected systems, it filters traffic to block unauthorized access to SCADA servers, complying with industry standards like IEC 62443 for industrial cybersecurity.
5. Monitoring & Diagnostics Layer
The module provides real-time visibility into network health via a web-based dashboard or integration with EMEROSN’s AMS Asset Monitor. Operators can track key metrics: Ethernet port status (link speed, packet count), serial port activity (baud rate, error rate), and redundancy status (ring health, power supply status). Alarms (e.g., “fiber link down,” “unauthorized access attempt”) are sent via email/SMS or MQTT to trigger immediate action, reducing troubleshooting time.
Example System Integration:
In a large automotive assembly plant, the NTE207-CBNS-0000 enhances network connectivity as follows:
- Protocol Conversion: Converts Modbus RTU signals from 50 legacy conveyor sensors (RS485) to PROFINET IRT, enabling integration with a Siemens S7-1500 PLC that controls the assembly line.
- Network Extension: Uses SFP fiber modules to extend the PROFINET network 5km from the central control room to the far end of the plant, connecting three remote welding cells.
- Redundancy: Configures a ring topology for the PROFINET network, ensuring the assembly line continues operating if a fiber link is damaged by a forklift.
- Security: Encrypts data between the PLC and a cloud-based MES (Manufacturing Execution System) using TLS 1.3, preventing unauthorized access to production data (e.g., cycle counts, defect rates).
