PM864A: Product OverviewThe PM864A (order code 3BHE039770R0102) is a high-performance controller module within ABB’s AC 800M series, designed specifically for System 800xA distributed control system (DCS) applications. This module functions as the computational core of the control system, executing regulatory control algorithms, sequence logic, advanced process optimization strategies, and safety instrumented functions. Installed in an AC 800M baseplate, the PM864A manages all controller operations, including scanning I/O modules via various fieldbus networks, executing application programs, handling communication with operator stations, and interfacing with higher-level systems.The controller operates as part of a modular system architecture where it coordinates with other modules in the controller chassis, including communication interfaces, power supply units, and co-processor modules. It runs the control application program developed with ABB’s Control Builder engineering tool, processing real-time data from field devices and executing control commands to maintain process variables within specified setpoints. The controller’s design focuses on high availability, deterministic performance, and cybersecurity for continuous process operations in critical industrial environments.

Core Features & Customer ValueThe dual-core processor architecture provides substantial computational power for complex control strategies including multi-variable predictive control, complex sequential operations, and custom calculations. For process engineers, this enables implementation of sophisticated control schemes that improve process stability, product quality, and energy efficiency. The deterministic scan time ensures consistent control loop execution, which is critical for maintaining process variables within tight tolerances in continuous process industries.Integrated support for multiple fieldbus protocols allows the controller to communicate with a wide range of field devices and remote I/O stations. This flexibility enables integration of diverse equipment into a unified control strategy, reducing system complexity and lifecycle costs. The controller’s high availability features, including 1:1 redundancy support and hot-swap capability, ensure continuous operation even during maintenance activities or component failures.Typical ApplicationsIn oil and gas production facilities, the PM864A controls complex processes such as gas compression, crude oil separation, and chemical injection systems. The controller manages safety instrumented functions (SIFs) while optimizing production throughput and ensuring compliance with safety standards.In pharmaceutical manufacturing, the controller executes batch recipes for drug substance production, providing precise control of temperature, pressure, and flow parameters while maintaining comprehensive electronic batch records for regulatory compliance.
