2.3 Selection and
reservation
The purpose of the reservation and selection is to prevent double opera-
tion, either in the bay itself or in the complete station. For an operation in
the bay, the reservation part always reserves the own bay. The engineer
can include or exclude the part that reserves other bays.
The selection and reservation function consists of four parts:
1. Reservation of the own bay
2. Requesting reservation of other bays and handling of the acknowledge-
ment signals
3. Replying to reservation requests
4. Permitting selection of apparatuses, depending on reservations
The selection and reservation function has two ways of starting. It starts
when a request select signal is set in the own bay or when it receives a
request for reservation from another bay.
