I am trying to communicate to a mini plc 95u 6es5 095 8mao3 the software iam using is step5 ver.7.17. Iam also using a laptop with windows 95, and every time i try to connect to it i get plc not online or plc timeout. Iam wandering if i need some other equipment for this hook up.

I am now using the db9 to db25 pin cable pc/rs 232 converter. I have had no luck with this for a while if anyone can help i would appeciate it. If anyone knows how this should work please give a explanation why it has not connected. RE: siemens simatic s5 (Industrial) 24 Dec 02 08:30. May be you should try 1st make 2 computers talking by rs232 using your unlucky port. So you will know that at least port and Windows driver operate ok.

Well, I'm out of ideas myself, but try (if you haven't already) to write to (OR Tel: ++49 (0) 180 5050 222). First they will bother you asking your personal details and determining which country tech supp will deal with you, be patient. Your initial email is quite ok for them to open a new case, though I would also specify convertor type as well as other possible things explicitly. RE: siemens simatic s5 (Electrical) 6 Jan 03 10:43. I also had problems running my DOS version of S5 software under Windows. When contacting Siemens, I was informed that DOS versions should not be run under Windows, and that I would need either an upgrade or a new 'Step-5 for Windows'.
I also have another Siemens programing software for S5 and S7 PLC's. This is available from IBHsoftec, I found these programs far easier and faster to use than the 'official' Siemens ones (they are also far cheaper). RE: siemens simatic s5 (Electrical) 26 Feb 03 01:59.
