ABB 1SAP130300R0271 is a high-performance CPU module from the AC500 PLC series, with the standard model designation PM573-ETH. It is designed for medium-to-large automation systems requiring high-speed processing and robust network communication. This module integrates an Ethernet port, dual serial interfaces, an SD card slot, and a local LCD display, delivering powerful control capabilities and flexible expansion options for complex industrial applications.

1SAP130300R0271 is the complete part number. PM573-ETH is the standard model name, where PM573 denotes the CPU series, and ETH indicates the integrated Ethernet interface. The suffix R0271 represents the hardware revision. It belongs to the ABB AC500 PLC product line, compatible with corresponding terminal bases and expansion modules of the same series.

The module operates on a 24 V DC power supply, with a voltage range of 20.4 V DC to 28.8 V DC. It features 512 kB flash memory for program storage and 512 kB RAM for user data. The execution speed is 0.06 μs for bit instructions, 0.09 μs for word instructions, and 0.7 μs for floating-point instructions. The operating temperature ranges from 0 °C to +60 °C, and the storage temperature from -40 °C to +70 °C. The protection class is IP20, and it complies with CE, UL, and RoHS certifications. It supports up to 320 digital inputs, 240 digital outputs, 160 analog inputs, and 160 analog outputs locally, with a maximum of 10 expansion modules.

It is equipped with one Ethernet RJ45 port supporting Modbus TCP, HTTP, FTP, and SNMP protocols for network communication and remote monitoring. Two configurable serial ports (COM1/COM2) support RS232 and RS485 modes, compatible with Modbus RTU, CS31, and ASCII protocols. An SD card slot enables program backup, restoration, and firmware updates. An integrated LCD display with physical keys allows local status monitoring, parameter configuration, and fault diagnosis without an external computer.

It provides high-speed processing power to execute complex control logic, process control, and motion control tasks efficiently. The multi-protocol communication interfaces enable seamless connection with HMIs, drives, instruments, and other field devices. The local display and keys facilitate on-site operation and maintenance. It supports large-scale I/O expansion to build comprehensive control systems and allows hot swapping of expansion modules during operation to simplify maintenance. The SD card enables fast program backup and offline firmware upgrades, enhancing system reliability and maintainability.

It is suitable for factory automation applications such as automotive production lines, machine tools, robotics, and packaging equipment. It is widely used in process industries including water treatment, chemical, pharmaceutical, and energy management systems. It also applies to intelligent building control, HVAC systems, and port/airport automation equipment. Additionally, it is an ideal choice for upgrading legacy automation systems to achieve Ethernet networking and remote monitoring functions.

Mount the module on a standard DIN rail and connect the 24 V DC power supply correctly. Install the corresponding terminal base and external I/O modules according to actual requirements. Connect communication cables and complete parameter configuration and program downloading via ABB Automation Builder software before formal operation. Keep the installation environment ventilated and dry, and ensure all wiring terminals are tightly connected. Back up programs regularly using the SD card. Perform routine inspections quarterly and comprehensive function tests annually. Always disconnect the power supply before disassembling or replacing modules to ensure operational safety.
