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

A method for the transmission of data between a first automation device (50, 12, 14, 18), such as operating - pc or central control unit and at least one second automation device (24, 40), such as field device by means of a canopen - bus (20, 22) with the use of a service - data - object as a sdo - service, whereby a in the first automation device (50, 12, 14, 18) implemented sdo - client a download - or upload - request to a in the at least one second automation device (24, 40) is implemented sdo - server,characterized by the,that the data by a in the first automation device (50, 12, 14, 18) or the at least one second automation device (24, 40) implemented application (54, 84) in a canopen - frame be encapsulated,that the canopen - frame with the encapsulated data per sdo - service in a or from a in an object dictionary (76) of the sdo - server (82) defined data - tunnel - object (80, 86) is sent and to transmit orthat the encapsulated data by the in the first or the at least one second automation device (24,..
