3.2.9 Communication
between modules
Interlocking
Two types of interlocking modules per diameter are defined. BH_LINE is
the connection from one line to the busbar and is used twice per diameter.
BH_CONN is the connection between the two lines of a diameter. The
busbar earthing switches must also be interlocked as described in the
BB_ES chapter.

The interlocking module is implemented per bay, which needs the status
indication of all switching devices of the own bay itself and some switch-
ing devices of other bays. The communication between modules in differ-
ent bays is performed via the station bus. For each bay-bay
communication direction, there is a need for two communication ele-
ments, one for sending and one for receiving. For sending, an Event Func-
tion block is used, and for receiving, a Multiple Command Function block
is used.
The command function block supervises the transmission itself. Each
communication error results in a deactivation of the data valid signal in
the command function block, which is used as a condition in the interlock-
ing logic.
The User's Guide for "Apparatus Control", 1MRK 580 150-XEN
describes how the interlocking information is exchanged between the
bays and also the reservation mechanism.
