9.2.4 Data Variables are valid only upon the occurrence of specific collection events. Data variables may be
queried by the host. An attempt to read a data variable item at the wrong time does not generate an error, but the
data reported may not have relevant meaning.
9.2.5 Data Item Requirements for Multi-Head, Multi-Site Equipment — Some variables may change value
depending on the processing state (whether or not resources are allocated to a virtual tester). See definition of
Virtual Tester.
Example: If calibration is done separately on two test-heads, and a virtual tester has been allocated resources only
from the more recently calibrated test-head, CalDate for that virtual tester may have a more recent date in the
READY state than it did in the IDLE state.
9.3 class, hard-bin, and soft-bin — Equipment is to maintain variables that provide three levels of granularity for
test results: class, hard-bin, and soft-bin. Classes, hard-bins, and soft-bins are defined within a process program, and
their values are made available during events. When unit testing has completed, the process program is to determine
the class, hard-bin, and soft-bin with which the unit is to be associated, based on the results of the testing.
