bays are then transferred over the station bus for evaluation in the IED. After the
evaluation the operation can be executed with high security.
This functionality is realized over the station bus by means of the function blocks
QCRSV and RESIN. The application principle is shown in Figure
The function block QCRSV handles the reservation. It sends out either the reservation
request to other bays or the acknowledgement if the bay has received a request from
another bay.
The other function block RESIN receives the reservation information from other bays.
The number of instances is the same as the number of involved bays (up to 60
instances are available). The received signals are either the request for reservation
from another bay or the acknowledgment from each bay respectively, which have
received a request from this bay. Also the information of valid transmission over the
station bus must be received.

Application principles for reservation over the station bus
The reservation can also be realized with external wiring according to the application
example in Figure
. This solution is realized with external auxiliary relays and
extra binary inputs and outputs in each IED, but without use of function blocks
QCRSV and RESIN.
