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 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
parameter
CtlModel defines which 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.
Normal security means that only the command is evaluated and the resulting position
is not supervised. Enhanced security means that the command sequence is supervised
in three steps, the selection, command evaluation and the supervision of position.
Each step ends up with a pulsed signal to indicate that the respective step in the
