BS EN 62439-4:2010+A1:2012

# BS EN 62439-4:2010+A1:2012: Industrial Ethernet Redundancy Standard## OverviewBS EN 62439-4:2010+A1:2012, also known as the "High-availability Automation Networks" standard, is a crucial specification for ensuring reliable industrial Ethernet communication. This British Standard, which is identical to the IEC 62439-4:2010/AMD1:2012, provides guidelines for implementing redundancy protocols in industrial Ethernet networks, helping to improve uptime, safety, and overall system performance.## Key Features and Benefits- **Redundancy Protocols**: The standard specifies four redundancy protocols - Parallel Redundancy Protocol (PRP), High-availability Seamless Redundancy (HSR), Distributed Redundancy Protocol (DRP), and Beacon Redundancy Protocol (BRP) - to ensure continuous network operation in the event of a single failure.- **Improved Uptime**: By implementing the redundancy protocols outlined in this standard, industrial Ethernet networks can maintain connectivity and continue operating even when a single component or link fails, minimizing downtime and disruptions.- **Enhanced Safety**: The redundancy mechanisms defined in BS EN 62439-4:2010+A1:2012 help to ensure that critical industrial systems, such as those used in manufacturing, process control, and transportation, remain operational, improving overall safety and reliability.- **Seamless Failover**: The standard's protocols, such as PRP and HSR, provide seamless failover between redundant network paths, ensuring that data transmission is not interrupted during a failure, which is crucial for time-sensitive applications.- **Compatibility**: This British Standard is harmonized with the IEC 62439-4:2010/AMD1:2012 standard, ensuring compatibility and interoperability between devices and systems that comply with the specification.## Technical Specifications- **Title**: BS EN 62439-4:2010+A1:2012- **ISBN**: 978 0 580 73808 1- **Price**: £290.00- **Scope**: This standard specifies redundancy protocols for industrial Ethernet networks, including: - Parallel Redundancy Protocol (PRP) - High-availability Seamless Redundancy (HSR) - Distributed Redundancy Protocol (DRP) - Beacon Redundancy Protocol (BRP)- **Application Areas**: Industrial automation, process control, transportation, and other critical systems that require high availability and reliable Ethernet communication.- **Compliance**: This British Standard is identical to the IEC 62439-4:2010/AMD1:2012 specification, ensuring global harmonization and interoperability.## ConclusionBS EN 62439-4:2010+A1:2012 is a essential standard for industrial Ethernet network operators and designers who require robust, redundant communication solutions. By implementing the redundancy protocols defined in this specification, organizations can improve the uptime, safety, and overall performance of their critical industrial systems, ensuring uninterrupted operations and enhanced productivity.
