PM-573-ETH 1SAP130300R0271 ABB Bailey

Product Dimensions：

The PM573-ETH serves as the "brain" of the AC500 system. It is a programmable logic controller module that mounts onto a standard terminal base. The "ETH" suffix highlights its built-in Ethernet interface, which supports various protocols for communication with other PLCs, HMI devices, and supervisory systems. This CPU is engineered to handle both discrete and analog signals through its expandable I/O architecture, making it suitable for medium to large-scale automation projects.

Product Parameters

The technical specifications of the PM573-ETH demonstrate its capability to handle demanding applications:

• Processor Type: High-speed 32-bit RISC processor.

• Program Memory: 512 KB of user program memory, providing ample space for complex logic and algorithms.

• Data Memory: 512 KB for data storage.

• Flash Memory: Integrated 2 MB for user data backup and project storage.

• Processing Speed: Approximately $0.05 \text{ \mu s}$ per binary instruction, ensuring rapid response times.

• Communication Interfaces: One integrated RJ45 Ethernet port (10/100 Mbps) and two serial interfaces (RS-232/RS-485) via the terminal base.

• Supported Protocols: Includes Modbus TCP, HTTP (Web Server), FTP, and UDP/IP via Ethernet, alongside Modbus RTU and CS31 on the serial ports.

• Expansion: Support for up to 10 local I/O expansion modules and connectivity for multiple fieldbus couplers like PROFIBUS DP or CANopen.

• Supply Voltage: 24 VDC (typically provided via the terminal base).

Product Advantages

One of the standout advantages of the PM573-ETH is its High Performance-to-Size Ratio, delivering significant computing power in a compact modular form. The Integrated Ethernet Port is a major benefit, allowing for easy remote diagnostics, web-based visualization, and high-speed data exchange without the need for additional communication modules.

The Flexible Expansion Capability allows users to scale the system from a simple controller to a complex networked architecture. Furthermore, it features a Reliable Memory Concept, utilizing non-volatile RAM and Flash memory to ensure that programs and critical data are preserved even during power outages. The module is also highly valued for its Advanced Programming Environment, as it is programmed using the Automation Builder software based on the industry-standard CODESYS (IEC 61131-3), which supports multiple languages like Ladder Diagram (LD) and Structured Text (ST).

Important Considerations and Precautions

When implementing the PM573-ETH, several key precautions should be followed to ensure system longevity and safety. First, Terminal Base Compatibility is crucial; the CPU requires a compatible terminal base (such as the TB511-ETH or TB521-ETH) to function, and these must be ordered separately.

Second, Environmental Protection is vital; the module is designed for indoor industrial use and should be installed in a cabinet with a minimum IP54 rating if the environment is dusty or humid. Third, Electrostatic Discharge (ESD) protection must be observed when handling the module to prevent damage to internal electronic components.

Fourth, regarding Firmware Updates, always ensure the CPU firmware is compatible with the version of Automation Builder being used to avoid communication errors. Finally, for the Ethernet Connection, it is recommended to use shielded twisted pair (STP) cables in high-noise industrial environments to maintain data integrity and prevent electromagnetic interference.

Product Applications

The ABB PM573-ETH is versatile and finds its place in many sectors that require reliable and fast control logic.

• Factory Automation: Controlling high-speed assembly lines, packaging machinery, and material handling systems where timing is critical.

• Process Industry: Managing water treatment facilities, pumping stations, and small chemical batch processes through its analog processing capabilities.

• Infrastructure and Building Control: Used in tunnel ventilation systems, large-scale HVAC control, and lighting management for commercial complexes.

• Energy Management: Monitoring and controlling power distribution systems and renewable energy installations like wind turbine sub-stations.

• Machine Tools: Providing the logic for complex CNC or metal-forming machinery that requires coordinated movement and high I/O counts.
