Today's PG and PC software requires increasingly more powerful              

programming devices. Depending on his needs, the user can decide            

to increase the working memory, install a higher capacity hard              

disk (or an additional one), or to install other special hard-              

ware that will improve the functionality of his programming                 



Whether or not such a modification is feasible must be decided              

on an individual basis. Your SIMATIC contact or the service engi-           

neer at your local Siemens office will be happy to provide advice           

(a list of contacts can be found in SIMATIC Info 95/     ).                 

In general, it is technically possible to upgrade the hardware              

of the above-listed programming devices.                                    


The programming devices can also be upgraded for the programming            

of SIMATIC S7 PLCs. The STEP 7 programming software necessitates            

the following basic configuration of the hardware:                          



        Minimum:        INTEL 80386 SX or DX                                

        Recommended:    INTEL 80486 SX or DX                                


        _Please note:_                                                      

        STEP 7 will only execute on systems with an 80486 micro-            

        processor (or better) with a satisfactory speed. The                

        S7 software will execute on 80386 systems in principle,             

        but the performance is very low, so that we discourage              

        the upgrading of such units for S7.                                 


Working memory:     Min. 8 Mbytes, recommended: 16 MBytes                   

Hard disk:          STEP 7 memory requirements: approx. 50 MBytes           

                    STEP 7 + Word f.W. 3.11:    approx. 80 MBytes           

On-line interface:  MPI/PPI                                                 

Programming interface:  For SIMATIC Memory Cards                            


Please also note that for reasons of warranty the installation              

of hard disks may only be carried out by an authorized Siemens              

Service and Maintenance Centre.
