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.
