6ES5 858-0AA11   TK 858 telecommunications unit                             

                                                                            

                                                                            

                                                                            

_Reason for the change:_                                                    

                                                                            

The functionality of the TK 858 telecommunications unit has been            

enhanced considerably. The new revision level permits the                   

following links via the worldwide telephone network:                        

                                                                            

_1) Programmer to PLC link with the STEP 5 package_                         

                                                                            

A number of telephone numbers can now be stored in the PLC; the             

total is limited is given by the PLC memory capacity only.                  

                                                                            

 2) Programmer to PLC link with PRODAVE DOS 511 via AS 511                  

_   protocol                                              _                 

                                                                            

The improved automatic dialling feature is particularly suited              

for combination with the PRODAVE DOS 511 package. The TK 858                

firmware has been improved for this purpose. On the PRODAVE side            

a new version of the PRODAVE Toolbox is required and will be                

available early in 1993.                                                    

                                                                            

_3) Programmer to PLC link with PRODAVE DOS 64R via RK 512_                 

                                                                            

This alternative permits a data link via CP 524/525 to a pro-               

grammer (or PC) under MS-DOS with the RK 512 computer link.                 

The PRODAVE DOS 64R software package for PG/PC-AT is required               

in this case.                                                               

                                                                            

_4) PLC to PLC link via RK 512_                                             

                                                                            

This link permits the communication of two PLCs with one another            

via CP 524/525 and RK 512.                                                  

                                                                            

                                                                            

_Upgrading:_                                                                

                                                                            

Please speak to your SIMATIC contact at your local Siemens                  

office if you wish to upgrade existing TK 858 units.
