LOYTEC L-Gate - Scope

L-Gate User Manual 12 LOYTEC
Version 3.2 LOYTEC electronics GmbH
The built-in Web server allows convenient device configuration through a standard Web
browser such as the Internet Explorer or Firefox. The Web interface also provides statistics
information for system installation and network troubleshooting.
In firmware 1.2 and up, the L-Gate supports user-defined network variable types (UNVTs)
as dynamic or external NVs, and can access configuration properties (CPs) on other
devices through file transfer. To transfer CPs it supports both the LonMark file transfer and
the read memory access method. For CPs, the standard (SCPTs) and user-defined (UCPTs)
are supported. All of those new CEA-709 data points can be mapped automatically to
BACnet objects.
In firmware versions from 3.0 and up, the L-Gate also supports Trendlog, Schedule and
Notification Class objects. These objects can be used to operate on any of the basic
BACnet objects, which are mapped to CEA-709 NVs. This allows the L-Gate to provide
trend data of one or more NVs, schedule NVs and BACnet objects, and report alarms based
on NV conditions directly in BACnet. There can be up to 100 scheduler and calendar
objects, up to 32 notification class objects, and up to 100 trend log objects with an
aggregated total log buffer size of 2MB.
Furthermore, the L-Gate provides LonMark scheduler/calendar objects, which can directly
schedule NVs or be translated to BACnet schedules/calendars. For alarm conditions, the L-
Gate can be configured to send E-Mails to pre-defined addresses.
The L-Gate is used for:
• connecting BACnet and CEA-709 networks,
• communicating on BACnet with either BACnet/IP or BACnet/MSTP,
• communicating on CEA-709 with either FT-10 or CEA-852 (IP channel on the
Intranet/Internet),
• accessing ANSI/CEA-709 network variables (NVs) and configuration properties (CPs)
in BACnet,
• supporting standard (SNVT, SCPT) and user-defined (UNVT, UCPT) types,
• accessing BACnet objects in ANSI/CEA-709 networks,
• scheduling BACnet objects and ANSI/CEA-709 network variables,
• translating BACnet schedules/calendars to LonMark schedules/calendars,
• trending BACnet objects,
• generating alarms using intrinsic reporting on BACnet objects,
• sending E-Mails on alarms or scheduled events.
1.2 Scope
This document covers L-Gate devices with firmware version 3.2 and the L-Gate
Configurator Software version 3.2. See Chapter 12 for differences between the different
L-Gate firmware versions.
