14.3.6.5 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
synchronism-check.
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 parameter
one of the two control models is used. The control model "direct with normal security" does not
require a select whereas, the "SBO with enhanced security" command model requires a select
before execution. The command sequence for a command with control mode SBO with enhanced
security is shown in figure 437, with control mode direct with normal security is shown in figure
438.
