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).
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.
