Key status
B15 Static Key selector :
1 : means static key
0 : means not static key
The static status bits given by a data base are set by test equipments. These bits are defined for each key.
A static Key contain only synchronous parameter (Produce with synchronous sample frequency). The
arrangement in the static key is always the same for one test installation programming.
B14 Parameter Selector for onboard test computer:
1 : ignored
0 : Computed
B13 Message Key structure :
1 : means “message” key structure
0 : means not “message’ key structure
B12 DELAY field selector :
1 : means “DELAY” field is used for all parameters carried in one key
0 : means “DELAY” field isn’t used for all parameters carried in one key
B11 onboard test computer transmitted data :
“1”: means onboard test computer produce parameters for an other test equipment
“0”: other case
