2-element floating point array
Same as PRESS_IS for CLD
hPa
CLD only; values of PRESS-IS at manufacturing check out time
Provides historical data on how the analyzer was set up during final check out
PRESS_IS
Analyzer: bidirectional; I/0 module: input
TIME
7-element integer array
Appropriate date and time values
None
Periodic time update variable
Year
Mouth
Day
Hour
Minute
Second
Day of week -not implemented
Used to synchronize the internal clocks of analyzers and 1/0 modules with that of the
control module. The CM updates this variable every few seconds, and if it is updated
twice within 5 seconds, the analyzer or 1/0 module updates its internal clock to this
time.
Bidirectional
None
Integer
