The Triconex System Access Application (TSAA) Device Integration Object (DI Object) is a software means of
integrating physical Triconex controllers with the Wonderware ArchestrA system platform for exchange of live data
and SOE data retrieval and message multicasting. Each DI Object represents a physical Triconex controller (Tricon,
Trident, or Tri-GP) using the TSAA protocol for communication with a one-to-one relationship between one Triconex
TSAA DI Object and its respective physical controller. Up to 254 controllers (nodes) are supported through the
simultaneous execution of multiple Triconex TSAA DI Objects. New features of the latest TSAA DI object include: •
Support for Tricon system version 11.2. • Support for an increased number of tagnames with a corresponding
increase in bin sizes in Tricon 11.2 and later systems with only TCMs installed. • The maximum number of
tagnames is now approximately 29,000 (previous versions supported a maximum of approximately 13,000
tagnames).
