9.5.6 PLC Conversion Table
The PLC protocol assignment list defines how a PLC request is routed via the second connection to
the destination connection.
The list box provides a list of all entries.
When you select an entry, the upper section of the dialog box automatically displays the associated
information.
You can now edit the Source and Destination fields.
Then click the Update -> button to update the selected entry.
With Add ->, you can add a new entry with the specified settings to the list.
The <- Delete button deletes the selected entry.
If you click Clear Table, all entries will be deleted without confirmation prompt.
Any changes you make will only be applied after you close the dialog box with OK.
Procedure
If a request with a corresponding protocol arrives at a specified address, the data is routed over the
second connection set to the respective protocol and forwarded to the destination address. Frames
with requests that do not match the specified PLC protocol and the other settings are ignored.
If no matching entry is found, the PLC request is replied with “Element not found”.
If you set a CLX connection as the destination, use Browse to select the name online from the PLC.
The associated data type is determined automatically. This procedure should be used for CLX in
order to avoid incorrect settings.
The entries refer to the selected protocol and apply to all connections with that protocol.

Source
