A process for the transmission of data via a canopen - bus, as well as the use of the method for configuring and / or parameterizing of field devices via the canopen - bus

摘要

The present invention relates to a method for the transmission of data between a first automation device, such as operating - pc or central control unit and at least one second automation device, such as field device, via a can - open - bus with the use of a service - data - object as a sdo - service, whereby a in the first automation device implemented sdo - client a download - or upload - request to a in the at least one second automation device implemented sdo - server, wherein the data by a in the first automation device or the at least one second automation device application implemented in a canopen - frame be encapsulated, wherein the can - open - frame with the encapsulated data per sdo - service in a or from a in an object dictionary of the sdo - server defined data - tunnel - object or transmitted is transmitted and wherein the encapsulated data by the in the first or the at least one second automation device are implemented using. In order to the configuration and / or parameterization of automation devices with modbus - server via a canopen - bus of the present invention is to simplify, it is provided that the method is used for configuring and / or parameterizing the at least one second automation device having modbus - server via the can - open - bus, that the data as heavy-duty configuration - and / or parameterization data in the form of a modbus - frames generated, and in the can - open - frame are encapsulated and in that the canopen - frame by means of sdo - download in the data - tunnel - object of the sdo - server of the at least one second automation device and is loaded to de-encapsulate.
