6.6.4 Loop
On certain modules of the system, loops can be switched for testing
purposes.
This is possible via the "Loop" mask that can be called up in the "Online
Functions" window.
In case of modules composed of several boards, possible loops are
displayed individually for each board provided that the expanded
configuration option has been selected and the boards have been defined.
