6ES5 846-.NA.1    IP 244, Std. FB for S5-155U                               



The following problems have occurred with some IP 244 modules:              

Undefined controller reactions as well as setting of one or all             

digital outputs during run-up.                                              


To assure proper functioning of the IP 244, we request you to               

carry out the following measures:                                           


1. Upgrading of the module to product version A13,                          

   and operation of the module in slots with battery backup                 



The upgrade is free of charge. Please contact your local                    

Siemens office.                                                             


Note: We would point out explicitly that the IP 244 may be                  

      plugged into slots with battery backup only. It follows               

      that the EU 183U and EU 184U expansion units cannot be used           

      with the IP 244. The Product Manuals of the PLCs in ques-             

      tion show which of the slots have battery backup. An over-            

      view to this effect is also available from your local                 

      Siemens office.                                                       


2. Upgrading of the Standard Function Blocks                                


Upgrading of the module may be carried out independently of                 

the replacement of Standard Function Blocks. It is advisable,               

however, to combine the two measures.                                       

The Standard Function Blocks will be replaced at no charge if               

you return the original diskette to your local Siemens office               

and request a replacement.
