"TwinCAT library repository not consistent" after sudden computer restart. How to resolve?

[florrens]

After a sudden computer restart (possibly due to a blue screen - but not sure, since docking station was used) my TwinCAT library repository is "not consistent". What is the best and easiest way to resolve this issue?

Visual Studio 2013 with bugfixes and XAE Shell are installed.

First of all I would make a backup of the repository C:\TwinCAT\3.1\Components\Plc\Managed Libraries  (e.g. ZIP archive)

Then you can try to delete the cache file lokated in C:\TwinCAT\3.1\Components\Plc\Managed Libraries .

If this not help, I would delete the compete Managed Libraries folder and install them again via the CpStudio / OES export .

If you also use other libraries,which are not managed by CpStudtio / OES- than you must reinstall them via the Library Manager in twincat.

Thank you for the fast solution! Deleting the cache file did not help in my case, I had to delete the complete Managed Libraries folder. However TwinCAT was not able to restore the folder automatically so I had to create the empty "Managed Libraries" folder again manually

You can try this method by using STD to install to your C: TwinCAT 3.1 Components Plc Managed Libraries. Of course, the prerequisite is that the files in STD are complete, as some Peripherals do not have a Configfile file.Good Luck!
