Method for determing the processing sequence of function blocks of an automated system and corresponding automated system

A method for determining the processing sequence of a function block of a technological function wherein the technological function comprises associated input and output signals and the function blocks for implementing the technological function are interconnected with one another, comprising:

• determining a first function block from that part of the function blocks and the block outputs that are in each case either unconnected or are exclusively one or a number of output signals of the technological function;
• determining a second function block, based on the first function block, is sought in the opposite direction to the signal flow direction, the block inputs of which are in each case either unconnected or receive one or a number of input signals from only the technological function;
• characterizing all block inputs, based on the second function block, in the case of the second and each of the subsequent function blocks in the signal flow direction up to and including the first function block, each being either unconnected or receiving an input signal only from the technological function or being connected to at least one block output of another function block, all the block inputs of which have already been characterized, in which the function block is marked as soon as all its block inputs are characterized;
• and
• determining the processing sequence of the function blocks according to the marking sequence of the function blocks.

An automated system for implementing the method for determining the processing sequence of a function block, comprising:

• a processing module;
• and
• a software code that can be implemented during the runtime of the software code on the automated system comprising;
• determining a first function block from that part of the function blocks and the block outputs that are in each case either unconnected or are exclusively one or a number of output signals of the technological function;
• determining a second function block, based on the first function block, is sought in the opposite direction to the signal flow direction, the block inputs of which are in each case either unconnected or receive one or a number of input signals from only the technological function;
• characterizing all block inputs, based on the second function block, in the case of the second and each of the subsequent function blocks in the signal flow direction up to and including the first function block, each being either unconnected or receiving an input signal only from the technological function or being connected to at least one block output of another function block, all the block inputs of which have already been characterized, in which the function block is marked as soon as all its block inputs are characterized;
• and
• determining the processing sequence of the function blocks according to the marking sequence of the function blocks.
