PROCÉDÉ DE MISE À JOUR LOGICIELLE SUR LES PASSERELLES DANS LES CLOUD, PROGRAMME INFORMATIQUE AVEC MISE EN OEUVRE DU PROCÉDÉ ET UNITÉ DE TRAITEMENT POUR RÉALISER LE PROCÉDÉ

摘要

The invention relates to a method and to a computer program (40) having an implementation of the method for updating software in a plurality of cloud gateways (20-24), by means of which cloud gateways automation solutions (12-16) are connected to the cloud (10), wherein a ranking of the cloud gateways (20-24) according to a hazard potential of the connected automation solutions (12-16) is determined, wherein the updating begins with the cloud gateway (20-24) or a group of cloud gateways (20-24) having the lowest hazard potential, wherein the success of the update occurring in the preceding step is checked before the updating is continued, wherein the updating is continued with a cloud gateway (20-24) or a group of cloud gateways (20-24) having the next higher hazard potential if, in the step for checking the success of the preceding update, it was determined that the update occurred without errors, or the updating is terminated altogether if, in the step for checking the success of the preceding update, it was determined that the update did not occur without errors, and wherein the steps of checking the success of the preceding update and of continuing the updating are repeated until the update has also occurred for the cloud gateway (20-24) or a group of cloud gateways (20-24) having the highest hazard potential.
