GEDI on Host 2 (redundancy)

Houns · Post by **Houns** » Tue Nov 19, 2019 3:55 pm

Hello,

I try to set up my first redundancy project with WinCC OA.
Redundancy is already configured and running.

During some tests I noticed that I couldn't open panels on the second host without problems.
I can start everything as usual, but there is a strange message when I want to open a panel "panel already in project".

If I choose the option "Open" I can edit the panel, but the top left icon is grey and if I want to save the panel threre is another error message:
"Write error - .. is not a file but a directory".

If I choose option "Open from Project", I get another error "Panel Read Error - ... is not a file but a directory".

So my question is: is it normal that I couldn't edit panels with the editor on the second host?

Host 1: Siemens IPC 427E, Windows 10, 64bit, WinCC OA v3.16 Patch 11
Host 2: VirtualMachine, Windows 10, 64bit, WinCC OA v3.16 Patch 11

The screenshots you can see in the attachment.

Kind regards

Houns

You error isn't REDU related. It looks like the user that runs GEDI has no OS Permissions to read or write files.

Hello again,

I tested it on a complete new system.
But I have the same problem.

The windows user is the same on both systems.
And within the GEDI I am logged in with "root".

Everything in the GEDI works (SystemMgm incl. redundancy overview, Para (editing values, creating DPs), vision, ...)
I can also create new panels and save and start them in QuickView.

But if I close them, I get the same error messages as described in the first post.

On the first redundancy partner everything works without problems.
Only if I use the GEDI on the second redundancy partner, I have the trouble....

Are there any restrictions for the GEDI on the second redundancy partner? I didn't find anything about it in the documentation....

Hello,

I found reason for my problem

The function for creating the WinCC OA project on the second host didn't work properly with our folder configuration.
Folders on Host 1:
C:\customer\visu\visu\_projectData_
Folders created by "copy redundant project":
C:\customer\visu\_projectData_

In one of the screenshots (panel read error) you can also see that the path is C:\Alpine\\ExVis\panels...

So one folder is missing.
I copy the project data to the correct target manually everything in GEDI is working.

I will try to see if the two consecutive folders with the same name cause the problem.

many thanks so far
