COM0003 2RAA005844A0006A
The COM0003 2RAA005844A0006A eliminates protocol barriers in hybrid industrial networks, allowing engineers to integrate legacy devices (e.g., Modbus RTU sensors) with modern Ethernet-based systems (e.g., PROFINET drives). For example, in a food processing plant, the module can connect vintage filling machines (using RS-485) with a new 800xA SCADA system over Ethernet, enabling real-time production data aggregation. Its hardware-accelerated protocol processing ensures low latency (<10 ms) even at full throughput, critical for synchronized control in high-speed packaging lines.
Engineered with conformal-coated PCBs and EMC shielding, the module withstands extreme conditions, including vibration (5 g, IEC 60068-2-6), humidity (95% RH), and electromagnetic interference from motors or transformers. This durability makes it suitable for outdoor installations in oil refineries or mining sites. The screwless terminal blocks and tool-less DIN rail mounting reduce installation time by 30%, while the IP20-rated enclosure protects against dust and accidental contact in factory environments.
The COM0003 2RAA005844A0006A incorporates secure boot, AES-256 encryption, and access control lists (ACLs) to prevent unauthorized access, compliant with IEC 62443 standards. In a pharmaceutical plant, these features ensure secure remote access for FDA audits while blocking cyber threats to batch control systems. The module’s integration with ABB’s Ability™ Remote Services enables predictive maintenance via real-time health monitoring, such as detecting declining network performance before failures occur.
The ABB COM0003 2RAA005844A0006A is indispensable in industries requiring robust and flexible industrial communication:
- Manufacturing: Connects PLCs, robots, and HMIs in automotive assembly lines, enabling real-time OEE (Overall Equipment Effectiveness) tracking. For example, in a tire factory, the module transmits data from ABB’s IRB robots (via EtherNet/IP) to a MES system, optimizing cycle times and reducing scrap rates.
- Power Generation: Integrates distributed control systems (DCS) with grid management platforms in thermal and renewable energy plants. In a wind farm, the module aggregates data from individual turbine controllers (Modbus TCP) and sends it to a central SCADA system over PROFINET, supporting predictive maintenance of gearboxes and generators.
- Oil and Gas: Facilitates secure remote access to offshore platform control systems, allowing engineers to monitor wellhead pressures (via RS-485 sensors) and adjust valve positions in real time. The module’s wide temperature range supports installations in arctic regions, where it maintains connectivity at -40°C.
- Water Treatment: Connects IoT gateways with legacy field devices in wastewater plants, such as integrating ultrasonic level sensors (Modbus RTU) with a cloud-based analytics platform (Ethernet/IP). This enables real-time monitoring of pump efficiency and chemical dosing systems, reducing energy consumption by 15%.

Pre-installation preparation: Mount the COM0003 2RAA005844A0006A on a DIN rail in a control cabinet, ensuring proper grounding and at least 50 mm of clearance for airflow. Terminate Ethernet cables with shielded RJ45 connectors and RS-485 cables with twisted-pair wiring, following ABB’s EMI mitigation guidelines. Configure IP addresses, protocols, and security settings via ABB’s Control Builder M or web interface, verifying connectivity with ping tests and protocol-specific diagnostics.
Maintenance recommendations: Inspect the module’s LED indicators monthly to confirm stable power and network links. In dusty environments, clean ventilation slots quarterly with compressed air to prevent thermal derating. Annually, review security logs for unauthorized access attempts and update firmware via ABB’s Software Manager to incorporate new protocol support or security patches. For redundant systems, test failover functionality by simulating a port or power failure to ensure seamless switching.
