Since V9.3 the serial license requirement has been removed so you shouldn't need an additional license.  I believe Tyler is referring to a landing module, where you address all the serial registers in this module, with control modules referencing the landing module. See below.

Beginning in version 12.3 of DeltaV, each serial dataset counts a 1 DST. The DST type is based on the type and direction of the dataset. Up to 100 integer or 50 floating point values can be in a single dataset. For instance, an entire input dataset of integer or floating point values counts as one AI DST.

Prior to version 12.3, the DST count of serial datasets was based on how the data values were used. If all 50 values (or 100, again based on whether the values are floats or integers) from a single dataset are used in a single module (sometimes called a landing module), the dataset consumes 1 DST. If the 100 values are used in 100 different modules, the dataset would consume 100 DSTs.

Moji, you didn't mention if the 500 digitals and 300 analogs were inputs or outputs, but lets assume they are inputs. Then also assuming they are in contiguous blocks of registers in the PLC, then in a V12.3 system, these values would require 5 DI and 3 AI DST's. Typically, I've seen digitals packed into integer words, so the 500 digitals would consume 32 integer values, which if in a contiguous block, would consume 1 AI DST.

When you create your dataset, you'll select input or output:

On the DeltaV tab, you'll select the signal type:
