F8652X 984865265 – HIMA F-Series CPU, 2x Ethernet, 256 MB RAM, SIL 3 Certified
Description
The HIMA F8652X(P/N:984865265)is a high-performance central processing unit(CPU)module developed by HIMA Paul Mauser GmbH for its next-generation HFX Series safety instrumented systems(SIS).As the core logic solver in safety-critical applications,the F8652X delivers exceptional processing power,advanced connectivity,and seamless integration with modern industrial networks.Engineered to meet IEC 61508 SIL 3 and other international safety standards,this CPU is designed for mission-critical environments in oil&gas,chemical processing,power generation,and offshore platforms.With support for ProvenTHOR engineering software,C/C++programming,and emerging technologies like OPC UA and Time-Sensitive Networking(TSN),the F8652X represents the future of high-availability safety automation.
Application Scenarios
At a liquefied natural gas(LNG)terminal in Qatar,the safety shutdown system must respond to emergency signals within milliseconds to prevent catastrophic events.The facility upgraded from legacy HIMA CPUs to the F8652X(984865265)across its HFX200 controllers.During a simulated pipeline rupture test,the F8652X processed over 1,200 safety inputs and executed complex shutdown logic in under 30 ms—40%faster than the previous system.The dual Ethernet ports enabled direct integration with the plant’s OPC UA server,allowing real-time safety data to be securely shared with the central operations center.The successful test validated the F8652X as a cornerstone of the terminal’s digital transformation and safety modernization strategy.

Technical Principles and Innovative Values
Innovation Point 1:Next-Gen Processing for Complex Safety Logic
With 256 MB RAM and 512 MB Flash,the F8652X handles large-scale safety programs,advanced diagnostics,and historical event logging—enabling more sophisticated safety strategies than legacy CPUs.
Innovation Point 2:Dual Gigabit Ethernet for Modern Network Integration
Unlike older CPUs with only 10/100 Mbps ports,the F8652X features dual Gigabit Ethernet,supporting OPC UA for secure,standardized data exchange with MES/SCADA systems and Time-Sensitive Networking(TSN)for converged IT/OT networks.
Innovation Point 3:Full Redundancy for Zero-Downtime Safety Systems
The F8652X supports hot-standby redundancy,where a backup CPU synchronizes in real-time and takes over within milliseconds upon failure—ensuring continuous safety coverage in 24/7 operations.
Innovation Point 4:Open Development with C/C++and ProvenTHOR
Beyond standard IEC 61131-3 languages,the F8652X supports C/C++programming,allowing developers to implement custom algorithms,encryption,or advanced control logic—future-proofing the safety system.
Application Cases and Industry Value
At a chemical plant in Germany,a series of near-misses highlighted the limitations of its aging safety system.Engineers replaced the CPUs with F8652X(984865265)units in a redundant HFX200 configuration.The faster scan times enabled more granular pressure and temperature monitoring,while OPC UA integration allowed safety data to be analyzed in the corporate cloud for predictive risk assessment.Over the next two years,the plant reported zero safety-related process deviations,and insurance premiums were reduced by 15%due to the enhanced safety architecture.
