Interaction between modules
A typical bay with apparatus control function consists of a combination of logical nodes or
functions that are described here:
•
The Switch controller (SCSWI) initializes all operations for one apparatus. It is the
command interface of the apparatus. It includes the position reporting as well as the
control of the position
•
The Circuit breaker (SXCBR) is the process interface to the circuit breaker for the
apparatus control function.
•
The Circuit switch (SXSWI) is the process interface to the disconnector or the earthing
switch for the apparatus control function.
•
The Bay control (QCBAY) fulfils the bay-level functions for the apparatuses, such as
operator place selection and blockings for the complete bay.
•
The Reservation (QCRSV) deals with the reservation function.
•
The Protection trip logic (SMPPTRC) connects the "trip" outputs of one or more protection
functions to a common "trip" to be transmitted to SXCBR.
