Abstract
Official abstract text for this publication.
An automation system made through a communication network and including: a first and second programmable logic controller respectively executing first and second automation applications to respectively control first and second sets of associated input/output modules; a third programmable logic controller, including a storage storing the first and second automation applications and configured to execute the first automation application to stand in for the first programmable logic controller, or to execute the second automation application to stand in for the second programmable logic controller.
First claim
Opening claim text (preview).
1 - 6 . (canceled) 7 . An automation system implemented through a communication network and comprising: a first programmable logic controller connected to the communication network and configured to execute a first automation application; a first set of input/output modules controlled by the first programmable logic controller through the communication network; a second programmable logic controller connected to the communication network and configured to execute a second automation application; a second set of input/output modules controlled by the second programmable logic controller through the communication network; a third programmable logic controller, as a backup programmable logic controller, connected to the communication network and configured to stand in for the first programmable logic controller or the second programmable logic controller when taken out of service; the backup programmable logic controller comprises storage means storing both the first automation application and the second automation application and is configured to execute the first automation application for purpose of standing in for the first programmable logic controller and controlling the first set of input/output modules, or to execute the second automation application for purpose of standing in for the second programmable logic controller and controlling the second set of input/output modules. 8 . The system as claimed in claim 7 , wherein the first programmable logic controller and the second programmable logic controller are connected to the backup programmable logic controller by a monitoring link. 9 . The system as claimed in claim 8 , wherein the backup programmable logic controller comprises means for detecting taking out of service of the first programmable logic controller or of the second programmable logic controller. 10 . The system as claimed in claim 8 , wherein the first programmable logic controller and the second programmable logic controller each comprise means for generating an image representative of an internal state and are configured to send this state to the backup programmable logic controller through the monitoring link. 11 . The system as claimed in claim 7 , wherein the first programmable logic controller stores the first automation application and the second automation application in a mass memory. 12 . The system as claimed in claim 7 , wherein the second programmable logic controller stores the first automation application and the second automation application in a mass memory.
