Hello!

I installed Step 7 v5.5 on my Windows 7 several weeks ago and I haven't been able yet to connect online to PLCs with the usb pc adapter. 

The problem is that when I try to select the USB conection in the "Local Connection" tab of the PG/PC selection window, it only appears the COM1 option.

I have read in the forum that the Step 7 v5.5 has implemented de usb drivers for the PG/PC but how can I select it?? Do I need to activate it or do something special??

Many thanks in advance!!

I attach the view of the local connection options of the PG/PC window (sorry it is in spanish blush)

Hello,
Although Step 7 V5.5 is compatible with Windows 7 as per mentioned in the following link:

But it is not clearly mentioned that the USB PC adapter is compatible with Windows 7.
Check Page 13 of this manual
Hope this helps.

Hello,

There is need it only to select the PC Adapter (Auto) and the other setting you could leave them by default. Frankly speaking I am using this kind of adapter but never checked what I have in options. If you a;lready tried and isn't working, perhaps reinstall of Step7 will solve the problem.

Best regards,

Hi,

if it's a first install, you need a PLC, because the PC adapter need 24V, from there.
So
1. plug adapter to usb,
2. plug adapter to PLC
3. install the driver from CD

after then you can select the USB.

Regards Zenta

Hello josemiall

May be should update firmware and driver for adapter.


For Windows 7 you must use the drivers from the SIMATIC Device Drivers. The driver on the CD USB Prommer 10/2007 / PC Adapter USB 10/2007 is not released for Windows 7.


see   Installation of the PC Adapter USB/USB Prommer Driver with STEP7 V5.5 http://support.automation.siemens.com/WW/view/en/44914284

Have you tried reinstalling the drivers for PC adapter USB indicate search the driver on the installation disk Step7, in the folder where you installed STEP7. May be step7 5.5 include new driver?

as variant - install XP-mode and SIMATIC PC Adapter USB Software V2.0. My colleagues argue that it works
