Scaling max in Data Array.
Scaling zero in Connected Node.
Scaling max in Connected Node.
Used to create an array of sequential
Object_Instances on an Object_Type.
When referencing Multistate properties,
allows the user to specify the index of the
property to be read. If 1 is specified, the
first one will be read, if 2 is specified, the
second will be read, etc. If 0 is specified,
the driver will return the total number
(count) of array items linked to the
property. If the parameter is not specified,
a list of all items will be returned. Refer to
Appendix
A.3.
Allows the driver to specify the write
priority used to write an output.
This parameter allows the linking of Map
Descriptors to an active read or write Map
Descriptor in order to construct a
ReadPropertyMultiple or
WritePropertyMultiple transaction. Refer
Appendix
A.9.
to
When the optional Length parameter is
set to a value N, the Map Descriptor will
include N consecutive instances of the
specified Object_Type. For example, if a
Map Descriptor specifies Object_Type,
Address 4 and Length 3, this means that
the AO instances 4, 5 and 6 will be
included in the read or write transaction.
The corresponding Data Array values are
in consecutive positions in the Data Array,
starting at the specified
Data_Array_Offset.
