Overview

The ABB PM864 is a high-performance processor module serving as the central controller in distributed control systems (DCS) and programmable logic controllers (PLC). Equipped with a dual-core 96 MHz processor, it executes complex control algorithms with low latency, making it ideal for real-time applications such as motor control, batch processing, and safety-critical operations.

The PM864 supports multiple industrial communication protocols—including Profibus DP, Profinet IO, Modbus TCP, and Ethernet/IP—allowing seamless integration with both legacy field devices and modern Ethernet-based networks. Its large memory capacity and redundant Ethernet ports ensure high availability and data integrity in mission-critical environments.

For example, in a chemical processing plant, the PM864 can manage thousands of I/O points while maintaining reliable, low-latency communication across multiple subsystems.

Technical Data
