A method for real-time data communication between subscribers in an automation network is provided. The automation network includes an active subscriber, a plurality of passive subscribers and at least a connecting unit. The method includes the active subscriber arranging n data packets to be transmitted in a transmission order with a total occupancy time duration of the transmission order, performing an optimizing procedure for determining an optimized transmission order with minimum total occupancy time, and transmitting the n data packets in the optimized transmission order to the passive subscribers. An active subscriber for carrying out the method and an automation network comprising an active subscriber are also provided.

Provided is a technology with which it is possible to access a function unit to be accessed without ascertaining an IP address of the function unit. Provided is a unit comprising: a communication unit for relaying a communication between an external device connected to a first network and another unit connected to a second network; a setting unit for acquiring address information of the other unit in the second network from the other unit and generating setting information in which the address information is associated with an identifier which substitutes for the address information; and a link information generation unit for generating, on the basis of the identifier, link information used to access information on the other unit from the external device.
