<p>The method involves constructing an overlay network comprising a decentralized network between the devices such as actuator (A4), control device (C1) and sensor (S5) representing a network node responsible for several keys and resources in the decentralized network. A resource with a same logical address (LA-A4,LA-S5) in accordance with a subscription to the resource during the initialization of first device and with a physical address (PA-A4,PA-S5) of the one of the second devices as resource content is published during initialization of the one of the second devices. The subscriptions to the resources, which are specified by the respective keys assigned to the resource and a subscribing device, are published. Each of the devices is accepted into the decentralized network as a network node during an initialization and functions as first and second device. The data at first device is sent to one of the second devices by the communication network or data at the one of the second devices is retrieved for each first device, during operation of the automation system.</p> |
