This link connects specifically a cTry component to a receiving component to be able to handle error in part of your Route.

To isolate the part of your Route likely to generate an error, you can put it in a Try block via the cTry component and its try link. Once isolated, if the Route generates an error, the error will by sent to the error handler unless a Catch block is found right after the Try block. For more information, see the catch section below.

The catch link can only be used with a cTry component and if a try link has already been used in order to isolate a part of a Route likely to generate an error.

So, the catch link catches the errors generated by the Route put in a Try block and enable you to handle it, if necessary, and continue the Route, if possible.

The finally link can only be used with a cTry component and if a try link has already been used to isolate part of a Route likely to generate an error.

The finally link will enable you to execute final instructions regardless of any problem that may occur in the Try and/or Catch block, to close a connection to a database, for example.
