Advantages and Features

• Dual High-Speed Industrial Ethernet: The integrated Ethernet TCP/IP and PROFINET ports on the ABB PM556-TP-ETH eliminate the need for additional communication modules, simplifying network architecture, reducing costs, and enabling direct connectivity to a vast ecosystem of devices and enterprise systems.
• Powerful Processing for Advanced Applications: With its strong CPU and ample memory, this PLC is suited for demanding tasks beyond simple logic, including PID control loops, data logging, recipe management, and basic motion control.
• Open and Flexible Network Integration: PROFINET support allows for deterministic communication with a wide range of standard I/O, drives, and sensors, while standard Ethernet provides easy access for programming, HMI, and MES/ERP connectivity.
• Seamless Engineering with Automation Builder: The controller is fully supported by ABB’s unified engineering environment, Automation Builder, which streamlines configuration, programming, commissioning, and diagnostics for the entire AC500 system.
• Scalable and Future-Proof: As part of the AC500 family, the PM556-TP-ETH can be easily scaled with a comprehensive range of I/O and specialty modules, protecting investments as application requirements grow.

Application Cases in Various Fields

• Packaging Machinery: Controlling complex form-fill-seal machines with integrated servo drives over PROFINET and communicating batch data to a supervisory system via Ethernet.
• Material Handling Systems: Acting as the main controller for conveyor and sortation systems, coordinating PROFINET remote I/O stations and exchanging parcel data with a warehouse management system (WMS).
• Water Treatment Plants: Managing chemical dosing, filtration cycles, and pump control while providing process data to a SCADA system via OPC UA or Modbus TCP over its Ethernet port.
• Automated Assembly Stations: Coordinating robots (via Ethernet), vision systems, and pneumatic valves (via remote I/O) in a synchronized production cell.

Comparisons with Competing Products

1. Vs. Other AC500 CPUs without PROFINET: Compared to a standard PM556 with only Ethernet, the PM556-TP-ETH offers the significant advantage of integrated, deterministic PROFINET I/O control, which is often a requirement in machine building and factories using this standard.
2. Vs. Competitor’s Mid-range PLCs (Siemens S7-1200/1500, Rockwell Automation CompactLogix): The ABB PM556-TP-ETH competes directly in this segment. Its key differentiator is the native dual-port Ethernet/PROFINET design, whereas competitors often require an add-on card for the second protocol. It also benefits from the integrated engineering environment of Automation Builder.
3. Vs. Using Separate Gateway Devices: Using a standard PLC plus an external PROFINET-to-fieldbus gateway adds complexity, cost, and potential points of failure. The integrated solution provided by the PM556-TP-ETH is more elegant and reliable.
4. Key Differentiator: Its standout feature is the convergence of standard IT Ethernet and real-time OT PROFINET in a single, powerful, and compact CPU unit, designed for the connected factory floor.

Selection Suggestions and Precautions

1. Network Protocol Requirements: Clearly define if your application requires PROFINET for I/O and drive control. If not, a standard Ethernet-only CPU might be more cost-effective. The TP-ETH suffix specifically denotes the PROFINET capability.
2. I/O Count and Performance Planning: Assess the total number of I/O points, the scan time requirements, and the complexity of the control program to ensure the PM556-TP-ETH‘s processing power and memory are adequate. Use ABB’s sizing tools if available.
3. Network Design and IP Addressing: Plan the IP addressing scheme for both Ethernet networks. The integrated switch functionality allows for line topology, simplifying cabling. Ensure proper network segmentation for traffic management and security.
4. Power Supply and Wiring: Provide a clean, well-regulated 24V DC power supply. Use appropriate wire gauges and ensure correct polarity. Consider using a redundant power supply for critical applications.
5. Software and Firmware Management: Use the latest stable version of Automation Builder. Check for and apply the latest firmware for the PM556-TP-ETH to ensure access to all features and security updates.
6. PROFINET Configuration: Properly configure the PROFINET controller settings, including device names, IP addresses, and I/O data exchange (modules) for all connected devices in the network view of Automation Builder.
7. Physical Installation and Environment: Install the PLC in a properly rated industrial enclosure with adequate cooling. Protect it from excessive dust, moisture, and electromagnetic interference from high-power cables.
