摘要：An interrogating device cyclically calling in an information from various inquirylocations controls the various inquiry locations differing in frequency to which endaddresses of the inquiry locations are stored a different number of times in aninterrogation control memory. When an interrogating device has not received anyinformation upon interrogation of an inquiry location, then this inquiry location is skippedthe next time. For this purpose, a note bit is stored in the interrogation control memoryat the address which was just interrogated. When the same memory location in theinterrogation memory is reached again after an interrogation cycle, the note bit effectsthat the address is not read and that the inquiry location is instead skipped once; thenote bit is thereby erased in turn.
