  • Associated product(s)

QUESTION:  
Why does the Technology CPU go into STOP with a message in the diagnostics buffer to the effect that there is a configuration error (error no.: 16#59A1) in the integrated S7 technology?

ANSWER:  
One possible cause of this behavior is that the technology system data has not been generated in the Hardware Configuration. Open the Hardware Configuration of your STEP 7 project and double-click on the S7 Technology (slot 3) of the Technology CPU. In the Technology system data tab you enable the Generate technology system data option and save the setting withOK.

Save and compile the Hardware Configuration and then you have to reload the system data blocks or the Hardware Configuration into the CPU.

More information is available in the manual "S7 Technology" in Entry ID: 30119663 .
