5.5 Map Descriptor Example: Write Controls
The following Map Descriptor will write controls to physical Server Genisys_01 and Genisys_02 (described in Client Side Node Descriptors section) whenever
any of the control statuses changes/updates. One such Map Descriptor is required per Node.
If Data_Type is Byte, 32 consecutive locations from the Data Array will be written to VHLC. Data at any location would be considered as one control word.
If Data_Type is Bit, 256 consecutive locations from the Data Array will be written to VHLC. Data at 8 consecutive locations would be considered as one control
word.
Also see Appendix A.1.

Name of one of
the Data Arrays
defined in
Data_Array
section. This
Data Array holds
control statuses
to be written to
other devices.
Starting offset
in the Data
Array which
holds the 1
st
control status.
One of the
Nodes declared
in the Node
Section.
Indications will
read from the
station address
belonging to this
Node Number of consecutive
locations in the Data
array to use when
issuing the Write
command.
Wrbx: send write command
to the Server when the
associated Controls updates
or changes. To write
continuously use Wrbc as the
function and add a
Scan_Interval parameter to
configure how often to write.
