LONworks/BACnet and Universal Gateways LGATE-9xx Series

LONworks/BACnet and Universal Gateways


The Loytec LGATE-900 is a CEA-709/BACnet gateway which allows seamless integration of systems using both communication standards by mapping CEA-709 network variables (NVs) to standard BACnet server objects. LGATE-900 is fully compliant with the standards CEA-709, CEA-852, and EN 14908 (LonMark system) as well as ASHRAE 135-2008 and ISO 16484-5. Analog, binary, and multistate BACnet objects (input/output) are mapped to NVs based on the CEN/TS 15231:2005 standard. BACnet properties are automatically configured with default values from the SNVT self-description. Scalar NVs are mapped to one BACnet object each. Structured NVs are mapped to several BACnet object, one for each member (members can be selected individually). Each LGATE-900 can handle up to 750 BACnet Objects. Several devices can be installed in a network at the same time. LGATE-95x allows a smooth integration between LonMark Systems, BACnet networks, KNX networks, Modbus devices, M-Bus devices as well as ZigBee PRO wireless devices. Network variables are mapped to binary, analog, or multi-state objects (input, output, value) according to the CEN/TS 15231:2005 standard. Data points can be manually or automatically generated across multiple protocols. In addition to analog, binary and multistate objects LGATE-95x supports alarming, scheduling and trending. They can be either connected through their Ethernet/IP ports to LonMark IP-852, BACnet/IP, KNXnet/IP and Modbus TCP simultaneously or to TP/FT-10, BACnet MS/TP channels, Modbus RTU and KNX TP1 respectively.
