• Communication Protocol: DeviceNet (master mode only).

• Baud Rate: 125 Kbps, 250 Kbps, 500 Kbps (configurable).

• Max Slave Nodes: 63 devices per module.

• Bus Length: Up to 500 m (depends on baud rate and cable type).

• Isolation: 500 V DC isolation between DeviceNet network and PLC internal bus.

• Operating Temperature: 0 °C to +60 °C; storage: −40 °C to +70 °C.

• Protection Class: IP20; certifications: CE, cULus, RoHS.

• Dimensions: 135 × 28 × 62 mm (H × W × D); weight: ~0.12 kg.

• Connector: 5‑pin pluggable spring terminal (COMBICON).

• LED Indicators: PWR, RUN, NET, and ERR for power, module status, network activity, and diagnostics.

Interface & Communication Configuration

• DeviceNet Master Interface: Single 5‑pin spring terminal port for DeviceNet network connection.

• PLC Bus Connection: Direct interface with AC500 CPU’s FBP bus for high‑speed internal data exchange.

• Isolation Design: 500 V DC electrical isolation protects PLC circuitry from network noise and voltage spikes.

• Software Configuration: Set baud rate, node address, I/O mapping, and slave parameters via ABB Automation Builder; supports EDS file import for third‑party DeviceNet devices.

• Termination: Requires 120 Ω termination resistors at both ends of the DeviceNet bus.

• Diagnostics: LED status indicators and system diagnostics enable quick troubleshooting of network faults, slave disconnections, or communication errors.

Core Functions

• DeviceNet Master Communication: Native master functionality to manage up to 63 DeviceNet slaves, enabling real‑time data exchange and control.

• High‑Speed Data Transfer: Supports 125–500 Kbps baud rates for fast, deterministic communication in industrial networks.

• Seamless Integration: Works with ABB AC500 CPUs and third‑party DeviceNet‑compliant devices for flexible system design.

• Hot‑Swap Support: Can be replaced without powering down the AC500 system, minimizing downtime during maintenance.

• Robust Diagnostics: Comprehensive LED indicators and software diagnostics simplify network monitoring and fault resolution.

Application Scenarios

• Factory automation: Automotive, packaging, and material handling lines using DeviceNet for I/O, drives, and sensor networking.

• Process industries: Water treatment, chemical, and pharmaceutical plants integrating DeviceNet‑based analytical instruments and control devices.

• Machine building: Standard machinery requiring cost‑effective, high‑speed DeviceNet connectivity for distributed I/O and motion control.

• Legacy system migration: Upgrading older DeviceNet‑based systems to ABB AC500 PLCs while retaining existing field devices.

• Industrial networking: Combining with Ethernet (CM577) or PROFIBUS (CM572) modules to build hybrid multi‑protocol networks.

Usage & Maintenance Instructions

• Mount on TH35‑15 DIN rail adjacent to AC500 CPU; connect to FBP bus via internal backplane connector.

• Wire DeviceNet network to 5‑pin terminal: CAN_H, CAN_L, GND, V+, and Shield; install 120 Ω termination resistors at bus ends.

• Configure baud rate, node address, and slave parameters in Automation Builder; import EDS files for third‑party devices.

• Keep the environment clean, dry, and well‑ventilated; inspect connectors and wiring quarterly for wear, loose connections, or corrosion.

• No user‑serviceable parts inside; replace the module if LEDs show persistent faults or communication failures occur.
