PLC Timeout in Step 5 v7.23 (works like a charm in Step 5 v6.6)

Hello everyone,

I have a strange problem that I hope someone could help me with.

This is what I have done:

I have 2x Windows XP VMWAREs (identical fresh installs)

1st one I have Step 5 v6.6 installed
2nd one I have Step 5 v7.23 HF1 installed

To these both I use my USB-RS232 adapter and PC-S5-CONVERTER cable (siemens official)

The VMWARE Step 5 v6.6 works like a charm and I can go online any day of the week with the default settings. But on the identical VMWARE where I installed 7.23 just gives me the usual "PLC Timeout".

Settings are identical, and same usb adapter drivers.

The only thing that differs is perhapps the way step 5 v6.6 & v7.23 installs into windows...

I have seen many many posts stating that you cant use a usb-rs232 adapter + official PG cable, but it works perfect in v6.6 so why not in 7.23 ;(

any ideas?

what is this difference in installation ways?

Well, I dont know. I just mean that maybe the installer handles differently? I should also mention that I have tried uninstalling sp3, and runnint on sp2 but still same problem. v6.6 works, v7.23 timesout , same cable, same windows installation.

Ok I thought you meant that you experienced a difference yourself.

I never installed S5 much so don't know very much about it actually.
A quick search brought up that after install and reboot you need to run install again and choose something like "windrivers" option... did you do that?

Yeah, and I also reinstalled both 7.23 and the usb drivers a couple of times in case, but still, only v6.6 works :/.

Well tough to say. maybe clone the VMWare with the 6.6, uninstall/delete 6.6 and try to install 7.23

A long shot:

change the com-port-number that is in use for the S5-adaptor?

Done it already several times. It must be something in the 6.6 install process that hooks the com port better than in the 7.23.. i can instal 6.6 anywhere and it just works.. but 7.23 doesnt no matter what I do. I know there are other options SW wise but step 5 7.23 is the standard at most of my clients and PGs so its just smoother to use the same all around
