Help... Siemens S5 Simatic PLC

Hi All,
Can anybody say how old this PLC is and is it possible to get modern Windows based software for it.
Is the S7 similar in programming?

Thanks in advance.... Declan

It is several years old, we still have tons of them, but are phasing them out over time. Yes, software is available for programming from windows. It runs in a Command Shell. I believe Siemens has quit supporting the S5 as of last Dec, although repair parts are still fairly widely available. Parts are getting scarce for the 805 NC control though.

Similar, yes, the same, no. The S7 is a much better PLC over the S5.

Has been around 8 years since I have done a new prodject using S5, and it was old then.
The only S5 software I have is DOS based. It will run on the newer windows systems but I've had no luck getting plc coms to work.
I got a cheap old Win 95 laptop for about 50 that I use for all the older PLC stuff.

50 pounds for a win 95 laptop!You should be paid 100 pounds for using that laptop.

That's good.In our college ( www.teiher.gr )we had some very old DOS computers, I think they were even 386s, you know with 5 1/4 floppies and monochrome displays, but they were working ok, just to practice ladder.We had some hitachi plcs, very odd for the 21st century.

Use a program like CPU kill, which slows the modern cpu's down. Launch a CMD box and start it up.
Works great with GEFanuc Series 5 kit.

S5 is dos based whereas S7 is windows based. If you can use S5 you should be able to migrate to S7 though the functionality of S7 is far greater than S5

"S5 for Windows" http://www.ibhsoftec-sps.de /
See the above page:
The company IBH Softec produces a program called "S5 for windows". Its been around for years and is well regarded. I've used both this and the authentic Siemesn version. A cut down trial version of S5 for windows can be downloaded for free, the full version can be purchased on line for less than 1/2 the price of the Siemens original. It also includes facilities for simulating your PLC in order to test software: that's a big time saver.
S5 for windows can be extended to allow S7 to be programed as well.
The Siemens S7 is much better and more powerfull than S5. Not only the saftware but alos the PLC's instruction set. The "Simatic Manager" that it comes with is probably the best integrated PLC programing sofftware on the market.
S7 looks like S5 but is IEC1131 complaint and as it has a BR or "binary reult bit" it is possible to not only avoid using jumps and therefore make code cleaner but it remain possible to do conditional execuion of ladder. Much better as you can used ladder for everything. (essential if you have electricians who must solve many problems in minimum time).
I usually use S5 for windows when I have a new engineer starting. Many can't use DOS anymore plus the simulator is usefull.
