Tag: HIMA H6200A

Description

The HIMA H6200A is a high-performance,redundant central processing unit(CPU)module from HIMA Paul Hildebrandt GmbH,designed for the HIMax®safety platform—a leading SIL 3-certified(per IEC 61508/61511)programmable electronic system used in safety-critical industrial applications.As part of HIMA’s H6000 series,the H6200A implements a 2-out-of-2 diversified(2oo2D)architecture:two independent microprocessors execute the same safety logic in parallel,with continuous cross-comparison to detect faults instantly.This ensures zero unsafe failures and enables continuous operation even during internal hardware faults—critical for emergency shutdown(ESD),fire&gas(F&G),burner management(BMS),and turbine control systems.

The module features dual Ethernet ports(for peer-to-peer redundancy and engineering access),integrated diagnostics,hot-swap capability,and support for PROFIsafe,Modbus TCP,and HART protocols.It operates within a modular HIMax chassis alongside I/O modules(e.g.,H6110A digital input,H6120A analog output),forming a complete,scalable safety instrumented system(SIS).Widely deployed in oil&gas platforms,LNG terminals,refineries,and power plants,the H6200A delivers maximum availability without compromising safety integrity.

Application Scenarios

At an offshore LNG production facility in the North Sea,a HIMA HIMax system with dual H6200A CPUs controls the process shutdown valves and firewater pumps.During a routine maintenance window,one CPU developed a memory parity error.Thanks to the 2oo2D architecture,the system continued operating safely on the second processor while alerting operators via the DCS.Technicians hot-swapped the faulty H6200A module in under 5 minutes—without triggering a plant trip.Post-replacement,the new CPU automatically synchronized its application logic from the active unit,restoring full redundancy.This incident demonstrated the H6200A’s fault tolerance,preventing an estimated$2M/hour production loss.

Technical Principles and Innovative Values

Innovation Point 1:True 2oo2D Fault Tolerance

Unlike 1oo2 or 2oo3 systems,2oo2D uses hardware-diverse processors(different silicon batches or architectures)to eliminate common-cause failures—maximizing both safety and availability.

Innovation Point 2:Zero-Configuration Redundancy

Dual H6200A modules auto-synchronize application logic and I/O states—no manual intervention required after replacement.

Innovation Point 3:Integrated Cybersecurity

Supports OPC UA with encryption,secure boot,and role-based access—meeting IEC 62443 requirements for modern SIS networks.

Innovation Point 4:Lifecycle Transparency

Full diagnostics logged to event recorder;compatible with HIMA Smart Safety for predictive maintenance and compliance reporting.

Application Cases and Industry Value

Refinery(Saudi Arabia):Uses H6200A-based HIMax for reactor overpressure protection.System has operated 10+years without spurious trips,meeting strict uptime KPIs.

Hydrogen Plant(Netherlands):Integrates H6200A with Siemens DCS via PROFIsafe,enabling safe coordination between basic process control and emergency isolation.
