Triconex System Access Application (TSAA) Device Integration Object (DI Object) is a software method that integrates physical Triconex controllers with the Wonderware ArchestrA system platform for real-time data exchange, SOE data retrieval, and message multicast. Each DI object represents a physical Triconex controller (Tricon, Trident domain Tri-GP), which communicates using the TSAA protocol and has a one-to-one relationship between a Triconex TSAA DI object and its respective physical controllers. Supports up to 254 controllers (nodes) by executing multiple Triconex TSAA DI objects simultaneously. The new features of the new TSAA DI object include support for Tricon system version 11.2. In Tricon 11.2 and updated systems with only TCMs installed, it is supported to increase the number of tagnames and correspondingly increase the size of bin. The large number of tagnames is now around 29000 (previous versions mostly supported around 13000 tagnames)
