1. A fieldbus system, comprising:
- a fieldbus;
a field device, which is connected to said fieldbus; and
a host computer, in which at least one of a device management unit or a control system for said field device is implemented and applies a device description file of said field device;
wherein;
in said device description file, a data transmission object for data exchange between said field device and said host computer or an additional field device is defined, which includes a plurality of freely loadable, transmission berths;
said device description file, serves to establish that the data transmission object has a certain number of transmission berths for input variables, which are transmitted in the data transmission object from the field device to the host computer or to the additional field device;
orsaid device description file, serves to establish that the data transmission object has a certain number of transmission berths for output variables, which are transmitted in the data transmission object from said host computer or from said additional field device to the field device;
said field device provides variables to be transmitted and includes a data mapping structure, which effects an association of variables to be transmitted with transmission berths of said data transmission object; and
the field device is also configured to completely or partially transmit the mapping information contained in the data mapping structure from the field device to the host device or to the additional field device.

13. A method for transmitting data between a field device and a host computer or an additional field device, comprising the steps of:
-
setting up a data transmission object corresponding to a device description file, wherein the data transmission object includes a plurality of freely loadable, transmission berths; assigning of variables to be transmitted to transmission berths corresponding to a data mapping structure, wherein the data mapping structure is present on the field device and mapping information for the data mapping structure is partially or completely transmitted from the field device to the host computer or to the additional field device, and transmitting the variables to be transmitted in the data transmission object between the field device and the host computer or the additional field device, wherein; providing that the data transmission object has a certain number of transmission berths for input variables, which are transmitted in the data transmission object from the field device to the host computer or to the additional field device;
orproviding that the data transmission object has a certain number of transmission berths for output variables, which are transmitted in the data transmission object from the host computer or from the additional field device to the field device.
