1 Introduction
1.1 Overview
The L-INX product family consists of high performance, reliable and secure network
infrastructure components that implement an embedded automation server. The different
models of the L-INX family contain a number of components and network technologies. As
protocols on the control network side, the L-INX implements access to BACnet, CEA-709,
Modbus, and M-Bus.
Data from the supported network technologies are available as data points in the automation
server. Those data points are freely configurable via configuration software, which provides
a fast and easy way to configure the L-INX using online network scans, import/export
features or device templates. Data points between different network technologies can be
connected to each other for data transfer between those network technologies (gateway).
Data points are also subject to alarming, trending and scheduling (AST) functions of the
automation server. The usage of math objects allows basic calculations and the built-in E-
mail client allows the L-INX to transmit E-mails on certain conditions. Generated alarms
can be configured to send e-mails to predefined addresses. Alarms can also be stored in a
historical alarm log. Trended data collected by the L-INX is available in CSV format and
through a dedicated Web service.
An embedded OPC server exposes a defined set of data points as OPC tags. It implements
the OPC XML-DA standard OPC XML-DA 1.01, which lets OPC clients access the data
points via Web services. Which native data points are exposed to OPC can also be
configured by the configuration software. AST objects such as schedules are exposed as a
set of OPC tags. Using the supplied L-WEB designer, users can easily generate a Web-
based visualization for the LINX.
The L-INX contains a freely programmable controller that can operate on all L-INX data
points. The controller application is developed using the provided IEC-61131 compliant
design tool.
The device permanently collects statistical information from the attached network channels
(OPC connections, FT traffic, MS/TP token passing, Ethernet traffic, etc.). Using this data,
the device is able to detect problems on these channels (overload, lost tokens, connection
problems, etc.) and warns the system operator via LEDs (see Section 3.4). An intuitive user
interface allows fast and easy network troubleshooting without any additional analysis tools
or deep system knowledge.
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. Some L-INX devices also
have an LCD display, which provides a quick way to configure basic settings of the device

via a jog dial. Also available on some L-INX models are ports for SD card memory, USB
peripheral bus and a 2-port Ethernet Switch/Hub.
The L-INX is used for:
Exposing data of control network devices from different technologies (CEA-709,
BACnet, Modbus, M-Bus) to data points in the automation server,
Directly connecting I/Os to data points in the automation server,
exposing data points to OPC tags,
visualization of data points with the supplied LOYTEC L-WEB software,
visualization of data points in an OPC XML-DA SCADA package,
running IEC61131 programs to control data points,
automatic meter reading applications via M-Bus and Modbus,
building custom Web pages with active content,
browsing data points on the Web interface or LCD display,
scheduling data points,
trending data points,
generating alarms from data points,
logging alarms,
sending e-mails on alarms, trend logs, or scheduled events.
1.2 CEA-709.1
L-INX automation server models that have CEA-709 are equipped with an FT port
(CEA-709) and a 100Base-T Ethernet port (CEA-852). CEA-709 L-INX models come with
a router option or an RNI option. L-INX models with the router option contain a CEA-709
router between the FT and the IP-852 channel, which can be configured like an L-IP. It
includes a configuration server (CS) to manage the IP-852 channel. The L-INX models
without the router option contain a remote network interface (RNI) instead of the router for
remote network access. Please refer to Table 1 to learn, which L-INX models have CEA-
709 and the router option.
The CEA-709 L-INX device is fully compliant with ANSI/CEA-709, ANSI/CEA-852-A,
EN 14908. The CEA-709 node, that is going to be commissioned in the network, is always
connected to the FT port of the device.
The function of the CEA-709 node is to expose CEA-709 network variables (NVs) and
configuration properties (CPs) to data points in the automation server. The configuration
software can be run as LNS plug-in or stand-alone. The CEA-709 data points can be bound
in the CEA-709 network as NVs or operated as ―external NVs‖. External NVs are polled or
explicitly written to without allocating static or dynamic NVs on the device. In this case,
address information is supplied by the configuration software by importing e.g., a CSV file.
User-defined network variable types (UNVTs) can be used as dynamic or external NVs.
Configuration properties (CPs) on other devices can be accessed through file transfer. To
transfer CPs, the device supports both the LONMARK file transfer and the read memory
access method. For CPs, the standard SCPTs and user-defined UCPTs are supported. All
those CEA-709 data points can be exposed to the automation server.
The CEA-709 L-INX with the router option possesses a router between the CEA-852
interface (IP-852) and the FT interface. The CEA-852 interface can be used to connect the
L-INX to an IP-based high-speed backbone. The L-INX‘s router can be used as a standard

L-INX User Manual 19 LOYTEC
Version 4.0 LOYTEC electronics GmbH
CEA-709 configured router or it can be used as a self-learning plug&play router based on
the high-performance, well-proven routing core from our L-Switch plug&play multi-port
router devices (―smart switch mode‖). The self-learning router doesn‘t need a network
management tool for configuration but is a true plug&play and easy to use IP infrastructure
component. For a detailed description of the CEA-709 router‘s usage refer to the L-IP User
Manual [1].
The CEA-709 L-INX without the router option can be configured to run either on the
CEA-852 interface (IP-852 mode) or on the FT interface (FT mode). In the FT mode, the
device provides a remote network interface (RNI), which appears like a LOYTEC NIC-IP is
intended to be used together with the LOYTEC NIC software [3]. The RNI can be utilized
for remote access and configuration as well as trouble-shooting with the remote LPA. Please
consult our product literature for the LPA-IP to learn more about this IP-based CEA-709
protocol analyzer.
The CEA-709 technology in the L-INX allows for:
Exposing CEA-709 network variables (NVs) and configuration properties (CPs) as data
points to the automation server,
supporting standard (SNVT, SCPT) and user-defined (UNVT, UCPT) types,
scheduling CEA-709 network variables,
generating alarms over the LONMARK node object,
CEA-709 PC applications (as a CEA-709 network interface),
remote LPA functionality,
communicating on CEA-709 with either FT or IP-852 (IP channel on the
Intranet/Internet),
connecting an FT channel to a high-performance backbone using existing IP infra-
structure,
operating as a configuration server for IP-852 devices with the router option.
1.3 BACnet
L-INX automation server models that have BACnet are equipped with an MS/TP port and a
100Base-T Ethernet port (BACnet/IP). BACnet L-INX models with the router option also
contain a BACnet router between the MS/TP and the BACnet/IP ports, which can be
configured like an LIP-ME201. The router models also include a BACnet broadcast
management device (BBMD) to manage BACnet/IP internetworks, which span across IP
routers. BACnet models without the router can register as a foreign device (FD) with other
BBMDs. The device is fully compliant with ANSI/ASHRAE 135-2008 (1.5) and ISO
16484-5. Please refer to Table 1 to learn, which L-INX models have BACnet and the router
option.
The BACnet L-INX exposes BACnet server objects and client mappings to data points of
the automation server. For client mappings, the BACnet address information is supplied by
the configuration software by importing e.g., a CSV file or by performing an online network
scan.
The BACnet L-INX models also support the LOYTEC Alarming, Scheduling and Trending
(AST) features in native BACnet objects. The device provides BACnet scheduler/calendar
objects, which can directly schedule BACnet server objects, remote BACnet objects or non-
BACnet registers. For alarm conditions the device supports the intrinsic reporting method of
BACnet objects. Trend logs can be uploaded from the device via the native BACnet read
range.

L-INX User Manual 20 LOYTEC
Version 4.0 LOYTEC electronics GmbH
The BACnet L-INX with the router option possesses a BACnet router between the
BACnet/IP port and the MS/TP port. This router can be operated and configured like the
LIP-ME200 from LOYTEC. The BACnet/IP interface can be used to connect the L-INX to
an IP-based high-speed backbone. The L-INX also can act as a BBMD for a BACnet/IP
network. For a detailed description of the BACnet router‘s usage refer to the LIP-ME201
User Manual [2].
A BACnet L-INX without the router option can be configured to run either on the
BACnet/IP interface or on the MS/TP interface. In BACnet/IP mode, the L-INX can be
configured as a foreign device in another BBMD. It does not provide the BBMD
functionality itself.
The BACnet technology in the L-INX allows for:
Exposing local BACnet server objects (analog, binary, multi-state) and remote objects
(client mappings) to data points,
scheduling from native BACnet schedule and calendar objects,
trending to native BACnet trend log objects,
generating native BACnet alarms,
communicating with either MS/TP or BACnet/IP,
connecting an MS/TP network to a high-performance backbone using existing IP infra-
structure,
operation as a BBMD for a BACnet/IP network with the router option.
1.4 M-Bus
In addition to the basic network technologies the device supports the M-Bus interface
according to the standards EN 13757-2 and EN 13757-3. To gain access to the M-Bus
network, an external M-Bus interface such as the L-MBUS by LOYTEC must be attached
to the device. On devices with a serial port, the M-Bus interface is connected to the serial
connector. In this case the user needs to turn M-Bus support on and off via a DIP switch.
On devices without a serial port, the L-MBUS interface must be used and is connected to
the extension port (EXT).
Through the M-Bus interface the L-INX can be used to scan the attached M-Bus network
for devices, pull M-Bus data points into a configuration, connect those data points to other
technologies and expose M-Bus data points to the automation server. All AST functions can
be used directly on M-Bus data points. Especially trending data and polling for data on M-
Bus devices has been optimized for automatic meter reading applications.
For debugging purposes a protocol analyzer is included in the firmware and can be operated
via the Web-UI and the configuration software. For more information on how to set up the
device for using M-Bus, configuring and using M-Bus data points, refer to Chapter 10.
1.5 Modbus
In addition to the basic network technologies the device supports the Modbus RTU and the
Modbus TCP interface. To gain access to the Modbus network, the appropriate interfaces
have to be activated either in the Web UI or in the configuration software. Modbus RTU is
operated with 8N1. A Modbus port can either be operated as Modbus master or Modbus
slave.
