TAC Xenta 913
LONWORKS® /INET Gateway
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 L ONW ORKS®. It
also supports some manufacturer-specific protocols, like 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.
