High‑capacity BACnet and Modbus routing for enterprise‑scale building automation networks
The i‑Vu® XT BACnet® Link (XT‑LB) delivers robust BACnet routing, BBMD functionality, and large‑scale third‑party integration, enabling seamless connectivity across IP, MS/TP, ARCnet, and Modbus networks within the Carrier i‑Vu® Building Automation System.
Network & Integration Device
The i-Vu® XT BACnet link allows you to integrate other manufacturers’ equipment into the i-Vu® building automation system using the BACnet protocol, making it easy to tie in equipment such as VFDs, boilers, and lighting systems. Each i-Vu® XT BACnet link supports up to 1,500 third party BACnet points.
The i-Vu® XT BACnet link also routes BACnet messages between the i-Vu® building automation system backbone (BACnet/IP), and a subnetwork of i-Vu® controllers (BACnet MS/TP and/or BACnet ARCnet). It connects directly to the Ethernet LAN and provides the i-Vu® web server with access to the entire i-Vu system.
The i-Vu® XT BACnet link also extends an i-Vu® system, allowing individual BACnet MS/TP networks (with up to 60 controllers each), and BACnet ARCnet networks (with up to 99 controllers each), to be connected together via the i-Vu® building automation system backbone.
