A message transmission between communication subscribers in an automation system is controlled, wherein publisher applications and/or subscriber applications are executed on each of the communication subscribers, wherein the automation system comprises a message broker configured to enter subscriptions for specified topics for designated subscriber applications into a topic tree. In reaction to a message on a specified topic of the topic tree being published by a publisher application of a first of the plurality of communication subscribers on the first communication subscriber offering one or a plurality of services, the message broker determines whether a subscriber application of a second of the plurality of communication subscribers has been entered for the specified topic. If a subscriber application for the specified topic has been entered, the message broker transmits a message to the entered subscriber application of the second communication subscriber that one or the plurality of services are on offer.
A method for controlling a message transmission between communication subscribers in an automation system wherein one or a plurality of publisher applications and/or one or a plurality of subscriber applications are executed on each of the communication subscribers, wherein the subscriber applications are configured to receive information in the form of messages from the publisher applications, wherein the automation system comprises a message broker decoupling message transfer between the communication subscribers and handling all the messages, the message broker being configured to enter subscriptions for specified topics for designated subscriber applications into a topic tree, said method comprising the following steps:
A message broker for an automation system comprising a plurality of communication subscribers, wherein one or a plurality of publisher applications and/or one of a plurality of subscriber applications are executed on each of the communication subscribers, wherein the subscriber applications are configured to receive information in the form of messages from the publisher applications, wherein the message broker decouples message transfer between the communication subscribers and handles all the messages, wherein the message broker is configured to enter subscriptions for specified topics for designated subscriber applications into a topic tree, wherein, in reaction to a message on a specified topic of the topic tree being published by a publisher application of a first communication subscriber of the plurality of communication subscribers, the message indicating that the first communication subscriber offers one or a plurality of services, the message broker determines whether a subscriber application of a second communication subscriber of the plurality of communication subscribers has been entered for the specified topic or not and, if a subscriber application for the specified topic has been entered, transmits a message to the entered subscriber application of the second communication subscriber, the message informing that the one or the plurality of services are on offer.
An automation system, comprising a plurality of communication subscribers and a message broker, wherein one or a plurality of publisher applications and/or one or a plurality of subscriber applications are executed on each of the plurality of communication subscribers, wherein the subscriber applications are configured to receive information in the form of messages from publisher applications, wherein the message broker decouples message transfer between the communication subscribers and handles all the messages, wherein the message broker notifies if one of the communication subscribers offers one or a plurality of services, wherein the notification is made only on the fact that one or a plurality of the services are on offer and wherein the plurality of communication subscribers are selected from the following group of communication subscribers:
