Which software I can use to program the S7-200 PLC and please give the dtail of all accessories and interface device to connect my laptop with PLC processor.

Hello zafar;

From the S7200_e.pdf manual:

Cable, RS-232/PPI Multi-Master 6ES7 901--3CB30--0XA0
Cable, USB/PPI Multi-Master 6ES7 901--3DB30--0XA0
Software Order Number
STEP 7--Micro/WIN 32 (V4.0) Individual License (CD-ROM) 6ES7 810--2CC03--0YX0

Download the above-mentionned manual from Siemens' support website:

Hope this helps,
Daniel Chartier

Somebody could tell me at what price can I find this cable?

Thanks,
Cristina

139 Euro... :)

Only $100 for 1pic

The software is called Microwin. You can download a demo at this url:

Hi,

Well, Step7 MicroWin from siemens is used to program s7-200 if thats what you are asking.
And you will need a PPI adapter for connection.

You can get it from your local Siemens PLC dealer. It is not real pricey. It is called Microwin I think.

You will need some kind of adapter also available from your local Siemens PLC dealer. I suggest the USB to PPI adapter.

To program the Siemens S7-200, you need Siemens MicroWin programming software. This is not the same software as used to program the S7-300/400 series.

For the programming interface device, there are several different ones. As to which is the best one, that depends upon several factors including what sort of computer you have and what other Siemens hardware you may currently have or may possibly use in future.

Contact your local Siemens dealer for more information. They should be able to give you prices and options.

hi,

you can use Step7-micro/win for programming a s7-200 plc(see simatic industial software catalog)
but for communication you have to buy a PC/PPI- adaptor from siemens(serial or USB) for serial siemens orderno: 6ES7 901-3BF20-0XA0 (if you have to buy all of that it's better you look for another PLC-manufacturer with free software and a serial interface).

Hi,

everything you wanted to know about the s7-200 but were afraid to ask!

Hello,

Can you tell me if there is a cable similar with the cable USB/PPI from Siemens?

Thanks,
Cris

The Siemens software "STEP 7-Micro/WIN" is what you need.

I can make a program with my STEP 7-Micro/WIN 32 but if I try to open a project I get this error "Specified acces point not found". Does someone know what to do? Thanks...!

Hi,
Step7-MicroWin 32 is an old version of the s7-200 programming package,
if you don't really need it you should upgrade to V4.

(demo version http://www.automation.siemens.com/_en/s7-200/support/tools_downloads/m icrowin.html
100 uses or 60 days)

I've never seen this error, but I'm guessing at comms problems. Check that your com port is available (under windows, some other software may have locked it) and that it is configured correctly in the set PG/PC interface section. If you are using a PC/PPI converter, check that this is correctly configured.

Failing that, re-install OS and applications, that usually fixes windows problems. If your still not working, post again with more information, OS, hardware and precise nature of problem.

Hi,

My notebook doesn't have a serial port so I use USB-Serial cable. But Step 7 Micro Win still does not recognise the connection. Should I need a Siemens USB/PPI cable to connect?

I have tried using MicroWin with a USB to RS232 adapter. Sometimes it works, sometimes it does not. I ended up buying a PCMCIA to RS232 adapter. It always works, as does the USB PPI cable.

What type of PCMCIA card did you buy...?

I frequently get this error (because I keep forgetting to not do things incorrectly). For some reason it just doesn't like to open projects directly. Just open up the program from the start menu location or whatever shortcut, then open your project from the open menu. Hope that helps.

Simatic Step7 programming software which needs u to purchase license key. Also needs PC adapter which connects your PC comport to MPI port on the S7-200 CPU.

Hi,
No, it must be Step7-Micro/Win.
No licence key is needed, the software does not use dongles or token discs or other crippling techniques. in fact you can use the time limited version for free for 100 times or 60 days (approximately the time between windows
re-installs ;)

There are lots of options for connecting, most posts have mentioned the PC-PPI cables with Serial or USB connectivity, some, not all can connect as MPI, you need to read the fine manuals available on the Siemens website.
I like to use wireless Ethernet, It means I can sit in a warm canteen during commissioning :)

Marc Sinclair

Nope. S7-200 is PPI, not MPI.

Siemens offers a USB to PC cable or serial to PC cables. Check http://www.siemens.com/s7-200 for any info you might need.

You can use MicroWin from siemens and you need programming cable PPI/MPI serial or USB.

Siemens Microwin

PPI convertor

Programname Microwin
See siemens support for more information

check the siemens website of siemens to get these details...They should have all the details you are looking for. For manuals etc, try this site: http://www.ad.siemens.com/supporte

Anyways, you require 1. Microwin from Siemens, and 2. USB/PPI interface cable.

But, try their website, and read up some documentation from Siemens. It usually has all such details!

For this you could get an isolation transformer large enough to supply your test equipment and simply ground one side of the secondary and call it the neutral. Isolation transformers are sold for standard voltages and by the VA required. It overcomes a lot of regulatory problems if you can mount it inside the equipment rather than supplying outlets in which case many jurisdictions have problems with multiple neutral to ground connections. It's fine most places if you isolate inside a cabinet and earth ground the cabinet. Before you get too excited, you might want to use a scope to see just what the difference voltage spectrum is. I've seen a merry chase to find power leakage and ground potential differences that turned out to be fluorescent lighting hash and noise with no real power available, that is, the power frequency component was very low and quite acceptable and the rest was killed with a $10 line filter.

Please,

I have PLC ladder program made in Siemens STEP-5 PLC. Can I use it in STEP 7 MICRO/WIN 32? This means, can we importe the STEP-5 Ladder program to STEP-7 MICRO/WIN 32?

No you can not import the S5 program to S7 version. S5 is DOS based and S7 is Windows based.

Add to that the fact the S5 is more directly comparable to the S7/300 which is Step 7 not MicroWin.

Hi, S7-200 is good for doing easy control and Can be used Modbus, free port to connect with other equipment. If needing help, please email me.
