Hello M. Elmogey;

The programming software for the S7-200 PLCs is Step 7 Microwin.v4.0, now at SP9:

6ES7810-2CC03-0YX0

STEP7-MICRO/WIN V4.0 (SL)d/e/f/i/es/zh

SIMATIC S7, STEP 7-Micro/WIN V4.0, single license for 1 installation E-SW, SW and documentation on CD, Class A, 6 languages (de,en,fr,es,it,zh) executable in Windows XP SP3 (32 bit), Windows 7 (32/64 bit) Reference HW: SIMATIC S7-200

As you can see from the screenshot below, the software has been phased-out since 2015.This means that the product is not available easily from Siemens (possibly as spare parts, but with an uptick on price...).

Start by contacting your nearest Siemens rep. for pricing and availability of Microwin, you have access to the Contact & Partners link at the right of this page to help you find him locally. There are also some equipment resellers that still offer Microwin as part of their inventory, such as this one (I am not approving this enterprise as a ressource, I only found them on the Web, you can search for more yourself and select among the hits by country and pricing delivery times).

Hello M. Elmogey;

I am afraid not. Step 7 Microwin is only used to program S7-200 CPUs.

Logo! Soft Comfort is used to program Siemens LOGO! smart relays.

Step 7 v5,6 (and lower numbers) is used for Siemens S7-300 and S7-400 PLCs; the S7-400H redundant (fault tolerant) CPUs must be programmed exclusively with Step 7 v5.x.

Step 7 v1x (TIA Portal) comes in 2 versions:

- TIA Portal Basic can only program Siemens S7-1200 PLCs, and basic operator panels

- TIA Portal Professional can program Siemens S7-1200, S7-1500 and S7-300 or S7-400 PLCs with more types of panels and SCADA (note that the TIA Portal program for the S7-300/400 is not compatible with the Step 7 v5.x software).

There is also a Siemens DCS based on Siemens S7-400 CPUs referred to as PCS 7 which uses it own particular programming environment.

So the landscape for Siemens PLC families and programming software can be quite confusing for a beginner, and when you ask for help on the forum you must always tell us which PLC and which software you are using. 

And finally: there is no legal free programming software from Siemens, unless you count the trail versions of the softwares (fully functional for 21 days, after which you must purchase a valid license).

Hope this helps,

Daniel Chartier
