BACKUP SOFTWARE-HARDWARE SYSTEM FOR AUTOMATIC MONITORING AND CONTROL Russian patent published in 2011 - IPC G05B19/418 

FIELD: information technology.

SUBSTANCE: in the automation system, automation processors are connected to the system bus EN which is based on an Ethernet interface in form of an annular structure of series-connected network switches, each of two backed up automation processors is connected to network switches of the bus EN on two channels, on one channel to one switch and on the other channel to the other switch; backed up automation processors are connected to each other on separate serial interfaces and are fitted with means of controlling hot backup; input/output stations are backed up and contain backed up SP modules connected in pairs over signalling lines, fitted with means of controlling hot backup, and on two backed up interface modules connected to each other on separate serial interfaces with means of controlling hot backup; backed up automation processors are connected to interface modules of input/output stations over a backup bus ENL which is based on Industrial Ethernet with a radial communication topology.

EFFECT: high reliability, fast switching to backup equipment, freeing computational resources from the task of controlling backup.
