Description of Error:

The description of the parameters and local variable names for the block does not exist or cannot be assigned. The parameters and local variables are therefore displayed as pseudo-symbols and without comments.
This conflict occurs when you open an online block, if

· The block exists online in the programmable logic controller, but not offline in the S7 user program.

· A block is opened via "Accessible Nodes". In this case no S7 user program is linked to the programmable logic controller.

This conflict occurs when you open an offline block, if

· A block was copied to an S7 user program from the "Accessible Nodes" view or from the "Memory card".

· The function block associated with an instance data block you want to open does not exist.

· The UDT associated with a data block derived from this UDT does not exist.

To Correct or Avoid Error:

· Opening an online block

If a corresponding offline block exists, open the required block from the online view of the S7 user program.

· Opening an offline block

If the error occurs when you open an instance data block or a data block derived from a UDT, try copying the corresponding FB or UDT into the current S7 user program.

If the error occurs when you open a logic block or a data block which is not derived, change the pseudo-symbols in the variable declaration, if required, and then save the block.
