onWorks
®
Gateway
FUNCTIONAL FEATURES
• Freedom to migrate to open
systems
• Bridges the gap between two
protocols and communication
technologies
• Handles most common
protocols
• Easy to operate
• Reliable and cost effective
• Links chiller plants
• Integrates power meters
The TAC Xenta 913 is a cost-effective way to integrate a large variety of
products into a TAC network. The TAC Xenta 913 supports the most com-
monly used open protocols, such as MODBUS, BACnet and LonWorks
®
. It
also supports some manufacturer-specific protocols, e.g. I/NET and Clipsal
C-bus.
The TAC Xenta 913 acts as a gateway, and transfers data point values from
one network to another. Configuration is carried out using the TAC XBuilder
programming tool.
