OpenPCS redundant system
The SmartPLC redundant system of Echelon Software supports distributed I/O configuration based on convertible fieldbus architecture. This is easier to use than traditional dual-redundant and multi-redundant structures. Fault tolerance levels can be achieved by mixing and implementing single, double, and triple redundancy in the same system according to project requirements.
At the same time, it has standard plug-and-play functions, such as synchronization variables, redundant I/O bus control, program peer test, main CPU arbitration, automatic failover and advanced diagnostics.
The advantages of hot backup redundant software also include microcontrollers with a wide range of CPU performance, fault-tolerant I/O communication, and automatic program downloads. When failover occurs, the maximum synchronization time error is <1ms.
The configuration procedure of the redundant system has been integrated in the OpenPCS development environment. This tool can realize CPU redundancy function, provide the required system communication and synchronization function for the system.
The software also has diagnostic functions to troubleshoot, for example, synchronization network failures, CPU configuration mismatches, I/O bus failures, missing I/O function blocks and analog input trend monitoring.
Fully open redundancy solution
SmartPLC redundancy system is a fully open redundancy solution, providing fully open software. Based on this platform, users no longer need to design system solutions based on software architecture. SmartPLC allows users to build redundant implementations arbitrarily according to system requirements. In addition to CPU redundancy, users can integrate redundant networks together according to their actual conditions. Its openness even allows users to integrate custom redundant communications
