Data processing structure
First Claim
1. A data processing structure having a plurality of processors (20i) and a data bus (100) for data communication with a serial data structure, characterized in that the plurality of processors (20i) can each be connected to the data bus (100) in a parallel connection, and data communication via the data bus (100) with one of the plurality of processors (20i), preferably comprising programming this processor (20i), is permitted for this processor (20i) and prohibited for all the others (20j) of the plurality of processors.

Abstract
The invention relates to a data processing structure comprising a plurality of processors (20i) and a data bus (100) for a data communication with a serial data structure. The plurality of processors (20i) can be respectively coupled in parallel to the data bus (100), and a data communication via said data bus (100) with one of the processors (20i), preferably a programniing of said processor (20i), is authorised for the same (20i), but is blocked for all of the other (20j) processors.

6. A data processing structure having a plurality of processors (20i) which can be controlled via a field bus (30) in a parallel connection, and a data bus (100) for data communication with a serial data structure, characterized in that the plurality of processors (20i) can be connected both to the field bus (30) and to the data bus (100), in each case in a parallel connection, and
for data communication with one of the plurality of processors (20i) via the data bus (100), this processor (20i) is connected to the data bus (100), while all the others (20j) of the plurality of processors are disconnected from the data bus (100).

8. A method for data communication in a data processing structure having a plurality of processors (20i) and a data bus (100) for data communication with a serial data structure, the plurality of processors (20i) being capable of being connected to the data bus (100) in each case in a parallel connection, characterized by the steps:
-
(a) data communication via the data bus (100) is permitted for one (20i) of the plurality of processors, and (b) data communication via the data bus (100) is simultaneously prohibited for all the others (20j) of the plurality of processors. - View Dependent Claims (9)
