11.3 Apparatus control (APC)
The apparatus control function consists of four types of function blocks, which are connected in
a delivery-specific way between bays and to the station level. For that reason, test the total func-
tion in a system, that is, either in a complete delivery system as an acceptance test (FAT/SAT)
or as parts of that system.
11.4 Interlocking
Prepare the IED for verification of settings as outlined in section 1 "Overview" and section 2
"Preparing for test" in this chapter.
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 accep-
tance test (FAT/SAT) or as parts of that system.
