Abstract
The invention relates to a method for optimized transmission of data between a control device and a plurality of field devices that are connected to one another via an IP-based communications network, wherein the data transmission is controlled using a Profinet protocol. The invention further relates to a control and data transmission installation () that is particularly suited to the performance of the method. With the control and data transmission installation (), it is possible to transmit the data to be transmitted from a control device () to a group of field devices () in a single sum frame subdivided into data fields, and to transmit the data to be transmitted from a plurality of field devices to a control device likewise in only one common sum frame subdivided into data fields. In this manner, the transmission rate can be optimized with respect to standard Profinet frames.
