PG/PC interfaces missing

Hello ChristophD and thanks

Where the heck does /program data live? I can not locate it.....

Please see a screen shot of the network interfaces

by stopped working, I only mean I have no conectivity to any PLC by any means.

I can not use ethernet or DP connections

This was all fine, on a Simatic Field PG system but suddenly stopped, but I do not recall any event or system problem to explain it,

Can I simply reinstall the set PG-PC application??

Hello,

do the Interface work in Wondows can you ping a PLC?
Ther programdata folder is located in the root of the Systemdrive, you must enable the Windows Explorer Options "Show hidden files and folders"

A reinstall of thew set PG/PC is not possible but with the tips from the thread here you can reinstall the interfaces.

Regards

Christoph

Hello ChristophD

I will read the thread carefully, I apologise, it is the end of a long difficult day...

I have attached the log file, I will also read through this and see if it makes sense.

I have tried to ping PLC devices today with no luck, but I will also investigate this further tomorrow,

Hi again

Ok, I have confirmed my laptop will talk to plc ok now with DP driver.

However, ethernet is not working at all. The etehrnet ports are ok, and work with routers etc. I can ping the PLC so I know my ssttings are ok, but when I try to communicate with S7 i get error message "Online: can not load the selected communications driver"

I should mention although I might sound cluless, I have been able to connect to many different PLC/HMI devices using most methods for many years. I have always been satisfied that I understand how to configure the different drivers and interfaces in Siemens with absolutely no problem.

I have followed the help steps, and I have used the method described previously to remove the drivers and reinstall being careful to do so with admin rights.

It seems I need to reinstall the communications drivers (from the help for error 33:17088 mentioned above.

So I reinstalled S7 but no difference. (although maybe that is what fixed the DP driver)

can someone please advise a good process? Should I uninstall all software and reinstall (TIA Portal, S7 etc?)

Any help appreciated

Hello,

this kind of situation happened also to me, but I must roll back via Windows Recovery Point to solve this. probably maybe is another solution to this, look at Windows servicies and find Siemens service like s7dosHelp ???? like this, check if it's enabled, runing. If not try enable it that it can be runing. Give pls info.

Thank You!!!

That was all it was.

I saw some other posts talking about other services, but your answer is the one for my situation.

Very much appreciated

Hello,

you can try this:
delete the Folder /ProgramData/siemens/automation/Simatic OAM/data (ProgramData is a hidden folder, you must enable the show hidden Folders option in Windows Explorer)

Open a cmd Shell with adminstrator rights (cmd -> Run as Administrator)

type s7epaIMP64x.exe in the Admin shell.
