Product Description

The ABB PM581 is a powerful and versatile CPU designed for the AC500 PLC platform. It is a scalable, mid-range controller capable of handling complex control tasks, large volumes of I/O, and fast cycle times.

It executes the user program, manages data communication, and oversees the operation of all connected I/O modules (both local and remote). The PM581 typically includes an integrated memory for the application program, data, and system files.

• Function: Executes control logic (e.g., ladder diagram, structured text) and manages the entire PLC system.

• Interfaces: Features built-in communication ports for networking, programming, and diagnostics.

• System Role: It plugs directly into the AC500 terminal unit and connects to the module bus for fast communication with adjacent I/O modules.

Product Parameters

Product Advantages

• Scalability: Part of the AC500 platform, allowing easy expansion with various communication and I/O modules to fit any application size.

• Integrated Communication: Features built-in Ethernet ports (supporting protocols like Modbus TCP/IP) for seamless integration into plant networks and remote access.

• High Performance: Provides sufficient processing power and fast cycle times for demanding tasks like motion control, high-speed counting, and complex calculations.

• Standardized Programming: Programmed using the standardized IEC 61131-3 languages, making development and maintenance accessible to control engineers.

Precautions

• Terminal Unit: The PM581 CPU requires a compatible Terminal Unit (e.g., TU581) for power connection and mechanical mounting to the DIN rail.

• Firmware Updates: Always ensure the CPU is running the latest stable firmware version to benefit from bug fixes and new features.

• Memory Backup: While the CPU has non-volatile memory, it is crucial to regularly back up the application program and data to an external source (e.g., SD card, server).

• Grounding: Proper grounding of the system and shielding of communication cables are essential to maintain data integrity and protect the CPU from electrical noise.

Product Applications

The PM581 CPU is used in a wide range of industrial control and automation scenarios:

• Medium-Sized Machine Control: Controlling automated assembly lines, packaging machinery, and material handling systems.

• Infrastructure: Used in pump stations, water treatment facilities, and building management systems requiring robust and networked control.

• Process Automation: Controlling batch processes, simple chemical reactions, and manufacturing lines in industries like food & beverage and pharmaceuticals.

• Distributed Control Systems: Serving as a distributed controller communicating with a central SCADA or DCS system.
