Enabling of the switching
commands
Before a switching command is executed, the C232 checks the interlocking equations
defined in the interlocking logic to determine whether the switching command is
permissible. Bay interlock equations for operation with or without station interlock can be
defined. The assignment of the output of the interlocking logic to a switching command
determines the interlocking equation that defines, for example, the conditions for the
open command for operation without station interlock.
