Concerns the product with Order No.:                                        

                                                                            

6ES7 318-2AJ00-0AB0   all harware releases and firmware V1.1.3 or older     

                                                                            

                                                                            

No system function blocks (SFBs) may be called in the background OB 90      

of the above S7-300 CPUs. If you do, errors in program processing may       

result, or even CPU STOP.                                                   

                                                                            

System functions (SFCs) are not affected by this problem. The previous      

CPU series are also not affected.                                           

                                                                            

As a provisional remedy we advise you to transfer OB 90 program sections    

with SFB calls to the OB 1.                                                 

                                                                            

We will inform you via a separate SIMATIC Info as soon as the problem has   

been corrected with a new firmware version of the CPU 318.
