14.3.9.5 Operation principle
The Bay reserve (QCRSV) function handles the reservation. QCRSV function starts
to operate in two ways. It starts when there is a request for reservation of the own bay
or if there is a request for reservation from another bay. It is only possible to reserve
the function if it is not currently reserved. The signal that can reserve the own bay is
the input signal RES_RQx (x=1-8) coming from switch controller (SCWI). The
signals for request from another bay are the outputs RE_RQ_B and V_RE_RQ from
function block RESIN. These signals are included in signal EXCH_OUT from RESIN
and are connected to RES_DATA in QCRSV.
The parameters ParamRequestx (x=1-8) are chosen at reservation of the own bay only
(TRUE) or other bays (FALSE). To reserve the own bay only means that no
reservation request RES_BAYS is created.
Reservation request of own bay
If the reservation request comes from the own bay, the function QCRSV has to know
which apparatus the request comes from. This information is available with the input
signal RES_RQx and parameter ParamRequestx (where x=1-8 is the number of the
requesting apparatus). In order to decide if a reservation request of the current bay can
be permitted QCRSV has to know whether the own bay already is reserved by itself
or another bay. This information is available in the output signal RESERVED.
If the RESERVED output is not set, the selection is made with the output RES_GRTx
(where x=1-8 is the number of the requesting apparatus), which is connected to switch
