One of the Data
Arrays declared in
the Data_Array
section 4.1.
The Data from the
Node (Dev1) will
be stored in this
Data Array.
The Driver stores Data from
device (DEV1) with this
memory location as the
starting point and onward, in
Data Array DA_R1.
This means that the
FieldServer cannot poll
the target device but
monitors the device.
Extracted data from
incoming messages are
stored in Data Array
DA_R1
This is the
logical name of
the target
device having
the parameters
defined in
section 4.3.
Length forces driver to
reserve memory space
for this number of
elements, starting from
memory location defined
as Data_Array_Offset.
Length must be long
enough to store all data
from Node (Dev1)
