  2. Is it possible to extend the existing standard Logical Nodes and Common Data Classes?
  3. Which PLC library needs to be included for the communication stack in TwinCAT PLC Control?

? Is it possible to apply my own Logical Nodes and Common Data Classes?
!Yes, this is possible in the Telecontrol Configurator. By the usage of the configurator the own definitions will be written in an "own" XML database. The corresponding objects are available for each new configuration in the configurator. You will find further information under Private Logical Nodes and Private Common Data Classes.

? Is it possible to extend the existing standard Logical Nodes and Common Data Classes?
!Yes, extensions are possible. But it is not possible to take the name of the original and the extension can only be saved in the "private" XML database. How this works you will see under Private Logical Nodes and Private Common Data Classes.

? Which PLC library needs to be included for the communication stack in TwinCAT PLC Control?

!After a successfull installation the TcIEC61850Server.lib needs to be embedded into the TwinCAT PLC Control project out of the TwinCAT library register.
