1SAP140200R0270 is a high‑performance CPU module from the ABB AC500 PLC series, designated PM582‑ETH. It is designed for medium‑to‑high complexity industrial automation applications. The module integrates a 10/100 Mbps Ethernet port, two configurable serial ports, an LCD with keypad, and an SD card slot, delivering powerful processing and flexible communication for Ethernet‑enabled control systems and convenient local operation.

1SAP140200R0270 is the full order number. PM582 denotes an enhanced AC500 CPU; ETH stands for onboard Ethernet. R0270 indicates the hardware revision. It is fully compatible with AC500 bases, I/O modules, and FBP communication modules.

Power supply is 24 V DC (20.4–28.8 V DC) with reverse‑polarity protection and approx. 10 W power consumption. It provides 512 kB program Flash, 512 kB data RAM, and 64 kB retentive memory. Execution speeds: bit 0.05 μs, word 0.06 μs, float 0.5 μs. Operating temperature ranges from 0 °C to +60 °C; storage temperature from −40 °C to +70 °C. Protection class is IP20; certifications include CE, cULus, and RoHS. Dimensions are 62 × 76 × 67.5 mm; weight approx. 0.15 kg.

One 10/100 Mbps Ethernet port supports TCP/IP and Modbus TCP. Two configurable serial ports: COM1 (RS232), COM2 (RS485), both supporting Modbus RTU, CS31, and ASCII; COM1 can act as CS31 master. An SD card slot enables program backup/restore, firmware updates, and data logging. A local LCD and keys allow on‑site monitoring and setup without a PC. The FBP bus extension supports Profibus DP, CANopen, and other fieldbus modules.

It efficiently executes complex logic, process, and motion control with its 32‑bit RISC processor. The combined Ethernet and multi‑protocol serial interfaces ensure seamless connection to HMIs, drives, instruments, and SCADA systems. Local display and keys simplify commissioning and maintenance. It supports up to 320 digital inputs, 240 digital outputs, 160 analog inputs, and 160 analog outputs, with hot‑swap I/O capability. The SD card facilitates quick backups and offline firmware upgrades, enhancing system reliability and maintainability.

It is widely used in factory automation for complex lines, robotics, packaging machines, and machine tools. It suits process industries such as water treatment, HVAC, chemical, pharmaceutical, and food & beverage. It also applies to intelligent buildings, energy management, and medium‑scale power distribution automation. It is ideal for upgrading legacy systems to support Ethernet networking and remote monitoring.

Mount the module on a standard TH35‑15 DIN rail and connect 24 V DC power. Install the base and I/O modules, then wire Ethernet, serial, and FBP cables according to requirements. Configure and download programs via ABB Automation Builder before operation. Keep the environment dry and ventilated; check and tighten terminals regularly. Back up programs via SD card periodically. Perform quarterly inspections and annual comprehensive tests. Always disconnect power before disassembly or replacement to ensure safety.
