6ES5 262-8MB12   IP 262 closed-loop control module, S controller            

                                                                            

                                                                            

                                                                            

In isolated cases the binary inputs of the IP 262 closed-loop               

control module are being read wrongly.                                      

                                                                            

_Remedy:_                                                                   

                                                                            

1. If you do not use the binary inputs with your application:               

   Set the data words for the binary inputs (DW 48 to DW 51 in              

   DB 15) to "0".                                                           

                                                                            

2. If you require the binary inputs for your application:                   

   Please speak to your SIMATIC contact at your local Siemens               

   office about correcting the firmware.
