PLC, Siemens Step5 v7.14 and AMD Duron


Thread Starter

Hello to all friends in list.

I had to change my mother board and processor, now my machine runs with a AMD Duron 800MHz processor on a Chaintech 7AIA motherboard...
Surprise! The Siemens STEP5 v7.14 doesn't go online anymore! This happens either under Windows98 and DOS. On the same PC I ran an old Step5 v3.2 package which connected with the PLC
with no problems, so the system has no hardware problems.

Anybody got same or similar behaviors? Any hint?

thanks in advance

Hello Friends who are the readers of this doc!!!

I have worked on PC based automation. I prepare the ocx of the koyo, siemens S5 plc which can work on as511 protocol. Step 5 will work on window 3.1 not on win 98 or NT because it can not work on different type of system due to file system problem. If would u like to get more info pl. contact me.


I want to edit the progrmme on a Simatic S5-100U PLC by laptop PC with windows ME. Please tell me which softawre I have to use? and where it is available?
