Schneider Electric TAC Xenta driver for Niagara AX
The driver enables direct communication between Schneider Electric TAC Xenta controllers and Tridium Niagara AX powered devices. Xenta series include a range of freely programmable controllers, which support a proprietary TAC protocol on top of open LonTalk medium.
Niagara AX device with Xenta driver provides a unique and cost-effective solution for Schneider building management system retrofit, seamless integration of various protocols and convenient makeover of front-end software. Xenta devices should not be reprogrammed and original TAC Vista front-end could co exist with Niagara on the same network until the end of the commissioning.

Niagara AX uses a standard LON card to connect to Xenta network. Xenta device points and schedules are imported into Niagara automatically without complex engineering. They retain their names, descriptions and unit facets, which greatly simplifies integration process.
Key features:
 Works with all TAC Xenta devices
 Uses standard LON option card
 Provides automatic device discovery
 Imports points from program files
 Enables point read and write
 Physical inputs and outputs could be overridden, i.e. for maintenance
 Supports Xenta time schedules
 Enables read-only, write-only and read-write access to schedules
 Flexible point polling intervals
 Displays point names, descriptions and unit facets
 Ideal for retrofit application
