This Driver supports Superblocks since version 1.07. This feature allows Elipse E3 to group Tags configured in an application into blocks with the largest possible size, to optimize communication. To enable this feature in Elipse E3, users must configure I/O Driver's EnableReadGrouping property to True.

Not all data types support this feature. BCD data types and Counter and Timer areas cannot be grouped.

Support for grouping blocks of bits is not yet implemented in this Driver's current version, but it may be implemented in future versions.

Data type 29, which reads 16-bit integers and formats them as 32-bit Floats, also cannot be grouped in this Driver's current version.

For Tags with outputs in String format, it is recommended to use A, or ASCII, tables for grouping String readings via Superblocks. If the project opt by using ST, or String, tables, group readings are not allowed for this type of table.
