Hello again!

Thank you for your always help. I am impressed about the capability of the program!
I just face further newbe problem...

I implemented the crossroad example for training issues and could it also run. But now I face the following Problem:

1) I can not edit the Volume anymore. I always get the following message:
\"%LDH-E-ACCESS, no such access for this configuration\".

2) I can not edit my PlcPgm anymore it always resists in the view Mode.

Did I messed up something with the user rights. Thanks in advance for any ideas.

Peter

I could solve the problem by myself :o)
I just had to reopen the RootVolume from the \"Project List\" over the \"PwrVolumes\" and save it again, afterwards it worked fine.
