A4H254-8F8T P0973JP Full hardware module redundancy and fault tolerance

A4H254-8F8T P0973JP achieves double or quadruple hardware redundancy for each node, module, channel and signal type of control, network, I/O, power supply and monitoring; no single-point-of-failure failures, supports isomorphic or heteromorphic redundancy, and enhances the system’s functional safety and information security;

A4H254-8F8T P0973JP safety function module with hardware diagnostics, software diagnostics, engineering procedure diagnostics, etc., through the hardware random fault re-execution recovery, software diversity execution recovery, etc. to achieve rapid recovery of occasional failures; support for module redundancy configurations, multilevel voting mechanism, online hot replacement, 2-2-0 degradation in redundancy configurations; through the independent third-party functional safety IEC61508 SIL2 certification.

Collective control system, its hardware device adopts control equipment redundancy fault tolerance, performance degradation online monitoring, high adaptability intelligent module and other technologies, software platform adopts multi-domain engineering object model, cluster distributed real-time database, multi-language integrated programming and development environment, safety control and security prevention and other technologies; it is a new generation of high-quality and stable with high-reliability, high-safety, high-adaptability and large-scale characteristics. High-end master control system. Control station size: AIO:1024, DIO:2048; system size: AIO:63488, DIO:126976.
