Explanations

  • Original relay columns define the slot allocation of the different modules that are included in the relay to be modified.
  • Action column defines the action to be done per each slot of the relay.
    • Unchanged: slot is not affected by the modification
    • Changed: slot content is changed by the modification, that is, to another module type
    • Added: a new module is added to an empty slot by the modification
  • Modified relay columns define the slot allocation of the different modules after the modification is completed.
