800F-N3G Allen-Bradley

800F-N3G Allen-Bradley Communication Processor

Product  Description：

Allen-Bradley Communication Processor modules, developed by Rockwell Automation, serve as dedicated network hubs and bridge interfaces within ControlLogix, CompactLogix, and legacy PLC-5 or SLC 500 automation platforms. These modules offload complex communication workloads from the main central processing unit (CPU), ensuring that deterministic control task execution remains unhindered by external network traffic.

By facilitating high-speed data exchange, routing protocols, and bridging disparate fieldbus networks, Allen-Bradley communication processors enable seamless connectivity between controllers, human-machine interfaces (HMIs), supervisory control and data acquisition (SCADA) systems, motion drives, and third-party industrial equipment. Supporting primary open standards such as EtherNet/IP, ControlNet, DeviceNet, Modbus, and serial protocols, these processors form the backbone of Integrated Architecture and Connected Enterprise initiatives across automated industrial plants.

Product Parameters

• Supported Protocol Variants: EtherNet/IP, ControlNet, DeviceNet, DH+, Remote I/O, Modbus TCP/IP, Modbus RTU, and ASCII Serial.

• Data Transmission Rates: 10/100/1000 Mbps auto-negotiating for Ethernet variants; 5 Mbps for ControlNet; 125, 250, and 500 Kbps for DeviceNet.

• Maximum Client and Server Connections: Up to 128 or 256 CIP connections depending on model series and firmware revision.

• Backplane Interface: Direct high-speed chassis backplane communication with local CPU modules and peer adapters.

• Port Configurations: Single, dual, or multi-port RJ45 Ethernet connectors, BNC coaxial, 9-pin D-sub serial, and removable terminal block connectors.

• Network Topology Support: Linear, Star, and Device Level Ring (DLR) fault-tolerant network topologies.

• Operating Voltage: Powered directly through the chassis backplane bus, with select models supporting redundant power supply configurations.

• Firmware Memory: Flash memory for in-field firmware upgrades and configuration storage.

• Operating Temperature Range: 0°C to 60°C for standard modules; -25°C to 70°C for extreme environment variants.

• Certifications: c-UL-us, CE, ATEX, Class I Zone 2 hazardous locations, and Marine environment certifications.

Product Advantages

• Dedicated Controller Offloading: Handles network protocol stacks, messaging packets, and routing routines independently, preserving CPU processing capacity for real-time control execution.

• Multi-Network Bridging: Acts as a seamless bridge between different industrial networks, allowing data transfer across EtherNet/IP, ControlNet, DeviceNet, and legacy networks without complex code.

• Enhanced Network Resiliency: Supports Device Level Ring (DLR) technology, enabling single-fault tolerant network rings that maintain continuous communication if a cable breaks.

• Integrated Security Capabilities: Modern communication processors offer CIP Security support, providing data integrity, entity authentication, and protection against unauthorized network tampering.

• Simplified Software Configuration: Fully integrated into Studio 5000 Logix Designer with predefined Electronic Data Sheets (EDS) and Add-On Profiles (AOP) for rapid network setup and live diagnostics.

Important Precautions

• Network Traffic Segmentation: Implement proper industrial Ethernet switches with VLAN and IGMP snooping enabled to prevent multicast traffic flooding and network congestion.

• IP Address Management: Carefully document and configure IP addresses, subnet masks, and network gateways prior to system commissioning to prevent network address conflicts.

• Cable Shielding and Grounding: Use industrial-grade shielded twisted-pair cables (Cat5e/Cat6) and properly ground shield drains to avoid communication packet losses caused by electromagnetic noise.

• Firmware Compatibility: Verify that the firmware revision of the communication processor is fully compatible with the controller firmware and Studio 5000 software version.

• Physical Connector Protection: Unused network ports must be covered with dust caps to protect internal optics and electrical contacts from dust, moisture, and corrosive industrial atmospheres.

Product Applications

• Enterprise and SCADA Integration: Linking plant-floor controllers with supervisory systems, enterprise resource planning (ERP) databases, and cloud analytics.

• Machine-to-Machine Communication: Coordinating high-speed data exchanges between independent production lines, packaging cells, and robotic assembly stations.

• Third-Party Device Gateway: Connecting specialized industrial equipment such as weigh scales, barcode scanners, flow meters, and third-party PLCs into the Allen-Bradley ecosystem.

• Remote I/O and Drive Control: Transmitting deterministic motion and I/O signals across large manufacturing facilities to remote racks and variable frequency drives.

• Critical Infrastructure and Process Monitoring: Providing redundant network paths for continuous process monitoring in water treatment, oil and gas, and energy production facilities.
