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 grounding
switch for the apparatus control function.
