Memory Architecture
Features:
- Processor module. Memory 2MB. Interfaces: Ethernet, 2x RS232/485, FBP. Display (PM590-ETH)
- Built with an integrated LCD status display directly on the module's front face for fast, on-site diagnostics and configuration parameter tracking
- One RJ45 TCP/IP port featuring built-in web server capabilities, SNTP time synchronization, and standard industrial protocols like IEC60870-5-104
The ABB PM590-ETH 1SAP150000R0271 module boasts up to 2 MB of onboard program memory and ultra-high-speed data processing capabilities (instruction cycles down to microseconds), making it ideal for complex process control, high-speed counting, and large-scale logic operations. Equipped with an intuitive LCD text display, the module allows field engineers to directly read system status and diagnose faults without connecting to a computer, significantly improving the ease of field interaction and maintenance.
With its abundant physical ports, it is seamlessly compatible with various industrial network protocols, such as Modbus TCP/IP and CS31 bus. Meanwhile, through a dedicated basic I/O bus, it supports cascading expansion of up to 10 external I/O modules, enabling efficient connection and secure scheduling of thousands of sensors and actuators in the field.
The PM590-ETH 1SAP150000R0271 ABB Programmable Logic Controller Processor module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
According to the official engineering manual, this module has a very specific physical hardware layout:
Terminal base requirements: Module model 1SAP150000R0271 must always be mounted on a matching terminal base with the part number prefix 1SAPxxxxxxR0270 to ensure proper backplane pin alignment.
Expansion module limitations: The processor supports a local hardware stack consisting of up to 10 expansion I/O modules directly connected to its bus layout. This can accommodate up to 320 digital inputs and 160 analog inputs.
Equipped with 2 MB of internal user memory partition (total memory capacity up to 5,120 kB, of which approximately 2,048 kB is used for user programs and 3,072 kB for user data).
Integrated Communication Suite:
Onboard Ethernet: One RJ45 TCP/IP port with built-in web server functionality, SNTP time synchronization, and standard industrial protocols such as IEC60870-5-104.
Serial Communication: Two highly configurable serial interfaces supporting RS-232/RS-485 physical layers for programming or executing Modbus RTU/CS31 communication protocols.
Fieldbus Plug-in (FBP): A dedicated port for plug-and-play connection to other standard industrial buses.
