OK, and now start accessible nodes in Step7 and show which devices are this nodes.

Hello

I have only one device and it is not my program. Can you explain me what is this?

THANKS

ADI

select MPI=20 and press CTRL+D

then the Device Diagnostic is open and you can see which device, which MLFB and which FW Version

In you screenshot you see the program blocks which are stored on the device

so i think the problem "configure CP5611 A2" is solved, you can reach the device and can go online!

In your Screenshot "Screenshot - 9_3_2015 , 10_14_55 AM.png " you see the Online Data of the PLC.

It looks that there is no project loaded, only the System Blocks available.

Have you a Memory Card in the PLC?

If no then the Battery error can be a problem that the data are lost.
Have you the project of the PLC ?

If yes open it and gon online with it and check if the Data offline and online is the same.

Rewgards

Hello,

ok go to HWConfig and open the properties of the MPI Interface (Xou connected the MPI Interface , right?).

Can you post a screen shot of the Interface Configuration of the PLC in the Project?
Which Transmission Rate, which mode ....

If the PLC lost his data it use the default settings for the Interface (MPI, 187,5 kb) with this settings you found the PLC in accessible nodes.
If the project have another configuration like Transmission Rate = 1,5 Mb then Step7 used the projected settings from the project and can't reach the PLC online!
