6ES5 948-3UR21   CPU 948R for S5-155H                                       

                                                                            

                                                                            

_The following problems have been eliminated:_                              

                                                                            

- If the PG-PLC connection is disabled while one of the functions           

  "Transfer block", "Force Var." or "Status block" is being used,           

  a sporadic RAM comparison error or blocking of the interface              

  may occur.                                                                

                                                                            

- If the error DB is less than 2048 words, it will be erased                

  and generated with a length of 2048.                                      

                                                                            

New functions for matching with the CPU 948U:                               

                                                                            

- OB 129:       Interrogation of the battery condition.                     

- OB 180:       Variable data block access.                                 

- OB 181:       Test data block.                                            

- OB 182:       Copy data area.                                             

                                                                            

By mistake some CPUs with the new revision level were shipped               

without being marked correctly on the front (i.e. A01 is still              

crossed). The actual revision level can be verified either by use           

of the PG function "System parameters" or by checking the label             

on the 3 firmware EPROMs: S79200-G261-B901-02                               

                                     -B902-02                               

                                     -B903-02.                              

EPROMs with the old revision level have Nos. ending -01.                    

                                                                            

                                                                            

_Upgrading:_                                                                

                                                                            

Please note that in fault-tolerant systems CPUs with different              

revision levels may not be combined. Both CPUs must therefore               

be upgraded.                                                                

                                                                            

This can be done without interruption of the running process.               

Relevant information can be gathered from Vol. 1 of the manual,             

page 9-10.

Security information
In order to protect technical infrastructures, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art IT security concept. Siemens’ products and solutions constitute one element of such a concept. For more information about cyber security, please visit
