  • Method of protecting redundant servers coupled to a manufacturing executing system
    Patent number: 9696715
    Abstract: A method protects at least two redundant servers. The redundant servers act as main and shadow interfaces between respectively at least two redundant process servers coupled to a manufacturing execution system and at least two redundant control servers coupled to an automation part. Each of the servers is configured to receive automation data from each of the redundant control servers. A time of receipt and a tag are extracted from the automation data and are registered in a database coupled with the servers. If one of the tags is registered within a predefined delay after the time of receipt of the other tag, the server with the older time of receipt is set up as the main interface and the other server is set up as the shadow interface.
