Problem with ProFuzzy, Version 1.0
Concerns products with the Catalog Nos.: 6ES5 834-3MG.1 Profuzzy 6ES5 840-6FB.1 Compact fuzzy control The problem occurs, when a fuzzy project has been stored in the CPU already and the membership functions of an input or output are shifted relative to one another, such that the sequence of the membership functions changes. Due to the problem, the rules base is not loaded into the CPU in the case of the renewed transfer of the project, although it has been changed in the course of sorting. As a result, there may be a completely wrong rules base in the CPU that leads to erroneous output values. However, the correct fuzzy project is still loaded on the PG/PC. Provisional remedy: The data are transferred to the PLC correctly if you maintain the following sequence: "Write file" - "Read file" - "Transfer". We shall inform you as soon as the above problem has been eliminated. -------------------------------
