6ES7 810-2BC01-0YX3   STEP 7-Micro/WIN32 V3.1, upgrade CD ROM               



The STEP 7-Micro/WIN32 programming software for the SIMATIC S7-200 micro    

system is now available with version 3.1. This new version contains several 

new features and enhancements. However, some of the new functions require   

specific versions of the CPU firmware.                                      


New functions for all CPUs 21x and 22x:                                     


- Symbolic information table (with absolute address, symbol and symbol      

  comment following each network in LAD & FBD).                             

- Ability to view the symbol and absolute address for each element during   

  editing and status monitoring in LAD & FBD.                               

- Multiple network cut/copy/paste with both keyboard and mouse selection.   

- New improved view settings with preview of grid width in LAD & FBD.       

- Print preview for all settings with auto-display of current rung position 

  or selection.                                                             

- Ability to renumber subroutines & interrupts from the POU properties.     

- Symbolic names for subroutines, interrupts, and indirect addressing in    

  all editors.

- Wizard support for version 2.0 of the TD200 Text Display.                 


In addition, but only for 221 & 222 CPUs with firmware 1.1 or higher:       


- New operations: Byte Immediate Read, Byte Immediate Write, Get Port       

  Address, Set Port Address.

Special notes on using run-time download:                                   


Programs created with STEP 7-Micro/WIN V2.x and earlier may not have the    

proper program organization necessary (main, followed by ascending sub-     

routines, followed by ascending interrupt routines) that is necessary to    

support a download in the run mode. In such cases please proceed as follows 

to be able to use the new functions:                                        


Load the program once with STEP 7-Micro/WIN32 V3.1 in STOP mode; thereafter 

you can also load and edit in RUN mode.                                     


Operating systems supported:                                                


STEP 7-Micro/WIN32 V3.1 requires Microsoft Windows95, Windows98, Windows NT 

V4.0, or Windows 2000 for proper operation. This package is not designed    

for use with 16-bit operating systems such as Windows 3.1 or Windows 3.11.  


Windows 2000 support is limited to the PC/PPI cable, with a single network  

master. Separte service packs will be available at a future date which will 

allow additional communication options for the CP cards and for multi-      

master capability via the PC/PPI cable.                                     


CPUs supported:                                                             


STEP 7-Micro/WIN32 V3.1 supports all SIMATIC S7-200 CPUs, including the 21x 

series (CPU 210, CPU 212, CPU 214, CPU 215, CPU 216) and the 22x series     

(presently CPU 221, CPU 222, CPU 224 and CPU 226).                          




STEP 7-Micro/WIN32 V3.1 is upward compatible, i.e. projects created with    

earlier versions of STEP 7-Micro/WIN or STEP 7-Micro/DOS can be opened with 

STEP 7-Micro/WIN32 V3.1, but not vice versa.                                


Projects created with STEP 7-Micro/WIN V3.1 or STEP 7-Micro/WIN or STEP 7-  

Micro/DOS can be neither opened nor processed with STEP 7-Micro/WIN32 V3.1. 


Upgrading and form of supply:                                               


The upgrade software with the order no. 6ES7 810-2BC01-0YX3 is a cost-      

effective method of upgrading STEP 7-Micro/WIN16, STEP 7-Micro/WIN32 or     

STEP 7-Micro/DOS. STEP 7-Micro/WIN32 (V3.1) is only available on CD ROM.    

A diskette version is no longer available.
