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 and
performs the actual switching and is more or less the interface to the drive of one
apparatus. It includes the position handling 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
grounding 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 function (SELGGIO), deals with reservation of the bay.
•
The Four step overcurrent protection (OC4PTOC, 51/67) trips the breaker.
