Abstract: A method for operating a control arrangement for an energy network. The control arrangement has a cloud infrastructure with data processor resources and data storage resources. A first group of software modules is executed on the cloud infrastructure, and a second group of software modules is locally executed on a server computer arrangement. The first group and the second group are connected for data communication via interfaces. The interfaces utilize a public key infrastructure (PKI) for encryption.

Abstract: The invention relates to a system and a method for the condition-based maintenance of at least one decentralised technical installation. The system comprises recording means for recording condition values of the technical installation and transmission means for transmitting the recorded condition values to a central maintenance management system, which comprises first means for evaluating the condition values and second means for generating maintenance orders, depending on the result of the evaluation of the condition values. Said condition-based maintenance is operated, in particular when a global maintenance management system is used, by the transmission of condition values from an automation system via e-mail or HTTP transfer.
