Powerful Computing Performance
Equipped with a high-performance 32-bit microprocessor, the PM864A supports high-speed logic execution and advanced control algorithms, such as PID regulation, sequential control, and other complex process strategies. Its strong computational capability ensures real-time response in large-scale and time-critical industrial applications.

Multi-Protocol Industrial Communication
The module integrates multiple communication interfaces and supports mainstream industrial protocols—including PROFINET, Modbus, EtherNet/IP, and other AC 800M network services. It can seamlessly connect to field devices (sensors, actuators) as well as upper-level systems such as SCADA, HMI, and MES platforms, enabling efficient data exchange and remote operation.

High Reliability with Redundancy Support
The PM864A supports dual-processor hot-standby redundancy, allowing automatic switchover to the backup CPU in the event of a primary module failure. This ensures uninterrupted plant operation and meets the stringent availability and reliability requirements of industries such as chemical processing, petrochemical, and power generation.

Excellent Scalability
The processor is fully compatible with the AC 800M I/O family, including DI/DO and AI/AO modules, allowing flexible expansion of control channels. This enables the system to scale from small to large, adapting easily to diverse process-control architectures.
