Operation principle

The Switch controller (SCSWI) is provided with verification checks for the select -
execute sequence, that is, checks the conditions prior each step of the operation are
fulfilled. The involved functions for these condition verifications are interlocking,
reservation, blockings and synchrocheck.
Control handling
Two types of control models can be used. The two control models are "direct with
normal security" and "SBO (Select-Before-Operate) with enhanced security". The
