Direct Access is a toolbox written for MATLAB that uses the AF SDK from Aveva to read and write PI System data. Since the AF SDK is the lowest level mechanism for communicating directly with the PI System, Direct Access improves performance by eliminating extra hops, data type conversions, recordset packing and unpacking, and cell2mat calls that are often required with OLEDB, ODBC, and REST techniques.
This toolbox is valuable to existing users of the PI System that might also use MATLAB to analyze their process data, as well as existing MATLAB users who require access to data that is stored in the PI System. Since both products are widely used in virtually every industry, the target users are the intersection of all Aveva and MathWorks customers.
Compatible with 32 and 64-bit Windows® installations with AF SDK 2.6 or later
Product Highlights
- Connects MATLAB to the PI System for the reading and/or writing of data related to PI Asset Framework Attributes, PI Data Archive Points, as well as lists of either.
- Supports compressed, sampled, summary, archived, snapshot, and calculated data
Returns vectors and matrices for primitive data types
Supports server-side data filtering options
Optimized for low overhead and fewer over-the-wire calls
Provides secure data access using Microsoft Active Directory and standard PI System configuration
Datetime is the native timestamp return type, which includes flexible time zone support
