6.1.4 Advanced Example 1 :
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
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.)
The scan time
is only
important for
the active map
descriptor.
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
All these map
descriptors read
their data from
the same slave.
Slave is a DAP
and we are
reading status
information.
These
parameters need
to be typed in
exactly as
specified in this
manual. They
are case
sensitive.
The format of
the data
extracted
depends on the
parameter.
