Appendix B.5. Advanced Map Descriptor 1:Collecting Data From Multiple Fileds
// Client Side Nap Descriptors
Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, Node_name, Address, Length, DA_Func, DA_Field, Scan_Interval
A1, DA_AI3, 0, RDBC Node_A, 0, 1, dap-stat, temp, 5
A2, DA_AI3, 1, passive, Node_A, 0, 1, dap-stat, hum, 5
A3, DA_AI3, 2, passive, Node_A, 0, 1, dap-stat, d_temp, 5
A4, DA_AI3, 3, passive, Node_A, 0, 1, dap-stat, hiTemp, 5
A5, DA_AI3, 4, passive, Node_A, 0, 1, dap-stat, loTemp, 5
A6, DA_AI2, 0, passive, Node_A, 0, 1, dap-stat, cs_on, 5
A7, DA_AI2, 1, passive, Node_A, 0, 1, dap-stat, hs_on, 5
It would be sensible for DA_AI3 to be an
array of FLOATs because the temps and
humidity’s return real numbers with one
digit after the decimal point.
DA_AI2 could be any type of array other
than BIT because the values returned for
these parameters are whole numbers
less than 255.
All these Map Descriptors
address Node_A therefore
only one Map Descriptor
needs to read (rdbc) the
node. The remaining Map
Descriptors can be
passive (thus optimizing
communications.)
All these Map
Descriptors
read their data
from the same
Server
These parameters must be typed in exactly as specified in
this manual. They are case sensitive. The format of the
data extracted depends on the parameter.
Server is a
DAP reading
status
information.
The scan time
is only
important for
the active Map
Descriptor.
