Interlocking
The interlocking function consists of a bay-level part and a station-level
part. The interlocking is delivery specific and is realized by bay-to-bay
communication over the station bus. For that reason, test the function in a
system, that is, either in a complete delivery system as an acceptance test
(FAT/SAT) or as parts of that system.
