L-INX/L-GATE User Manual 9 LOYTEC
Version 7.2 LOYTEC electronics GmbH
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,
KNX, Modbus, and M-Bus. The BACnet models are BTL-certified B-BC devices.
The L-GATE product family is intended for use as universal gateways. They provide a
similar user interface and set of protocols as the L-INX family. The L-GATE provides data
access to a defined set of data points, which are mapped from one control network technology
to another control network technology. In particular, the CEA-709/BACnet Gateway
(LGATE-902) implements mappings between a set of CEA-709 network variables (NVs)
and a set of standard BACnet server objects. Which NVs are mapped to BACnet objects can
be configured by an LNS plug-in or stand-alone configuration software. The LGATE-902 is
equipped with a 100-BaseT Ethernet port (IP), an FT-10 port (CEA-709), and an RS-485 port
(MS/TP). The device is fully compliant with ANSI/CEA-709 and ENV14908,
ANSI/ASHRAE-135-2004 and ISO 16484. The LGATE-95X extends the 902 model with a
number of additional protocol ports and supports more data points for the gateway.
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 and L-GATE 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 and L-GATE 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
device and 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. For secure OPC communication some L-INX models add an OPC
UA server. 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 L-INX.
Only the L-INX family 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.

L-INX/L-GATE User Manual 10 LOYTEC
Version 7.2 LOYTEC electronics GmbH
The L-INX and the L-GATE permanently collect 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 6.4). An
intuitive user interface allows fast and easy network troubleshooting without any additional
analysis tools or deep system knowledge. For troubleshooting Ethernet protocols a local and
remote Wireshark packet capture can be configured (see Section 10.2).
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 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 and a USB
peripheral bus.
Some L-INX and L-GATE models are also equipped with a 2-port Ethernet Switch/Hub. In
switched mode an Ethernet daisy chain can be built, which reduces cabling effort. The two
Ethernet connectors can also be configured to work as two isolated IP interfaces. This can be
used to safely connect a local building network while keeping it isolated from WAN access,
that exposes some aspects using secure services. By using the external L-WLAN adapter, the
device also provides a WLAN interface, which can link to an existing access point, set up its
own access point or work in a wireless mesh network.
The L-INX is used for:
Exposing data of control network devices from different technologies (CEA-709,
BACnet, KNX, 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, UA SCADA package,
Room control, plant control running IEC61131 programs on data points,
automatic meter reading applications via M-Bus and Modbus,
meter gateway to BACnet using pulse counters or M-Bus and Modbus meters,
browsing data points on the Web interface or LCD display,
basic automation functions on data points (alarming, trending, scheduling),
logging alarms,
sending e-mails on alarms, trend logs, or scheduled events.
The L-GATE is used for:
Connecting data points between any supported control networks (CEA-709, BACnet,
KNX, Modbus, M-Bus) using the universal gateway function,
browsing data points on the Web interface or LCD display,
exposing data points to OPC tags,
basic automation functions on data points (alarming, trending, scheduling),
logging alarms,
sending e-mails on alarms, trend logs, or scheduled events,
gateway for ANSI/CEA-709 network variables (NVs) and configuration properties
(CPs),
gateway for standard (SNVT, SCPT) and user-defined (UNVT, UCPT) types.

L-INX/L-GATE User Manual 11 LOYTEC
Version 7.2 LOYTEC electronics GmbH
1.2 CEA-709.1
L-INX automation server models that have CEA-709 and all L-GATE models 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 device models
have CEA-709 and the router option.
The CEA-709 L-INX and L-GATE 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 or the gateway. 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 or the gateway.
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
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 [8].
The L-GATE and 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 and L-GATE allows for:
Exposing CEA-709 network variables (NVs) and configuration properties (CPs) as data
points to the automation server or gateway,
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),

L-INX/L-GATE User Manual 12 LOYTEC
Version 7.2 LOYTEC electronics GmbH
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 and all L-GATE models are BTL-
certified products that implement the B-BC profile. They are equipped with an MS/TP port
and a 100Base-T Ethernet port (BACnet/IP). The MS/TP port supports remote Wireshark
packet capture for troubleshooting. 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 135-2010 (1.7) and ISO 16484-
5. Please refer to Table 1 to learn, which device models have BACnet and the router option.
The BACnet L-INX and the L-GATE expose BACnet server objects and client mappings to
data points of the automation server or the gateway. 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 and L-GATE 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.
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
[9].
A BACnet L-INX without the router option and the L-GATE 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. The BACnet L-INX without the router
option does not provide the BBMD functionality itself. The L-GATE can also be configured
to be a BBMD. Please refer to Table 1 to learn, which models can be configured as a BBMD.
The BACnet technology in the L-INX and L-GATE allows for:
Using the device as a BTL-certified B-BC,
exposing local BACnet server objects (analog, binary, multi-state) and remote objects
(client mappings) to data points,
scheduling any data point from native BACnet schedule and calendar objects,
trending any data point to native BACnet trend log objects,
generating native BACnet alarms on any data point,
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,

L-INX/L-GATE User Manual 13 LOYTEC
Version 7.2 LOYTEC electronics GmbH
troubleshoot the MS/TP network with Wireshark remote packet capture (see Section
10.2),
distributing NTP time into the BACnet network as BACnet time master.
1.4 M-Bus
In addition to the basic network technologies all models except the LGATE-900 support the
M-Bus interface according to the standards EN 13757-2 and EN 13757-3. To get 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 the M-Bus Chapter
in the LINX Configurator User Manual [2].
1.5 Modbus
In addition to the basic network technologies the all models support the Modbus RTU and
the Modbus TCP interface. To get 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.
On some BACnet L-INX models, the Modbus RTU and BACnet MS/TP protocols share the
same port. On those models, Modbus RTU can only be used, if BACnet MS/TP is disabled.
Please refer to Table 1 to learn, which BACnet L-INX models have this restriction.
Through the Modbus interface the device can be used to data points to other technologies,
and expose Modbus data points to OPC tags. All AST functions can be used directly on
Modbus data points. Especially trending data and polling for data on Modbus 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 Modbus, configuring and using Modbus data points, refer to the Modbus
Chapter in the LINX Configurator User Manual [2].

EnOcean wireless devices (see Section 1.12). To gain access to an EnOcean network, the
LENO-800 interface has to be attached via one of the USB ports USB 1 or USB 2.
The EnOcean interface is represented in the Configurator as a technology folder. EnOcean
devices are created from device templates and provide data points, which can be used with
the AST functions, the OPC server and also the PLC on the L-INX models.
For debugging purposes a protocol analyzer is included in the firmware and can be operated
via the Web UI. For more information on how to set up the device for using EnOcean,
configuring and using EnOcean data points, refer to the EnOcean Chapter in the LINX
Configurator User Manual [2].
1.8 SMI
In addition to the basic network technologies, some L-INX and L-GATE models can be
connected to SMI networks (see Section 1.12). To get access to the SMI network, the
LSMI-800 interface has to be attached to the EXT port of the device (for one SMI channel),
or the LSMI-804 interface to the USB port (for four SMI channels).
The SMI interface is represented in the Configurator as a technology folder. SMI devices are
created from device templates and provide data points, which can be used with the AST
functions, the OPC server and also the PLC on the L-INX models.
For debugging purposes a protocol analyzer is included in the firmware and can be operated
via the Web UI. For more information on how to set up the device for using SMI, configuring
and using SMI data points, refer to the SMI Chapter in the LINX Configurator User Manual
[2].
1.9 MP-Bus
In addition to the basic network technologies, some L-INX and L-GATE models can be
connected to MP-Bus networks (see Section 1.12). To get access to the MP-Bus network, the
LMPBUS-804 interface has to be attached to the built-in USB ports USB 1 and USB 2. Up
to two LMPBUS-804 interfaces can be operated at the same time, covering a maximum of 8
MP-Bus channels. External USB hubs are not supported.
The MP-Bus interface is represented in the Configurator as a technology folder. MP-Bus
devices are created from device templates and provide data points, which can be used with
the AST functions, the OPC server and also the PLC on the L-INX models.
For debugging purposes a protocol analyzer is included in the firmware and can be operated
via the Web UI. For more information on how to set up the device for using MP-Bus,
configuring and using MP-Bus data points, refer to the MP-Bus Chapter in the LINX
Configurator User Manual [2].

L-INX/L-GATE User Manual 15 LOYTEC
Version 7.2 LOYTEC electronics GmbH
1.10 L-IOB
The L-INX automation server models allow connecting physical I/Os to the device via the
L-IOB I/O modules (see Table 1). On some models those modules can be stacked up directly
to the L-INX using the LIOB-Connect feature (see Section 1.12). The connected I/O modules
are automatically identified and coupled as data points into the L-INX automation server. All
L-INX models also support easy integration of L-IOB I/O modules over FT cabling using the
LIOB-FT feature, or over Ethernet using the LIOB-IP feature.
L-IOB modules are available with digital inputs and outputs, analog inputs and outputs and
universal inputs that are configurable. Some models are also available with a differential
pressure sensor.
The I/O modules can be parameterized over the configuration software or the Web UI. All
parameterization data is stored on the L-INX and can be reloaded to the LIOB modules when
needed. The exchange of modules is detected automatically. For more information on how
to setup and use L-IOB I/Os please refer to the L-IOB user manual [7].
1.11 Scripting
Select programmable L-INX and L-GATE models provide a JavaScript-based scripting
engine (see Table 1 and Table 2). On some of them, a license (L-IOT1) needs to be purchased
to enable the feature. The script engine allows users to implement custom protocols using
RESTful APIs, JSON, Web services for IoT integration into the LOYTEC data point model.
The dpal-js API gives JavaScript modules access to the data point server. Script modules are
embedded into and deployed along with the data point configuration.
The Web interface of the LOYTEC device offers an overview of installed script modules and
allows starting scripts in debug mode. The debug mode implements the inspector interface
of Google Chrome to debug JavaScript on the device. For more information read the new
Scripting Chapter in the LINX Configurator User Manual [2].
1.12 L-INX and L-GATE Models
This Section provides an overview of the different L-INX and L-GATE models in Table 1
and Table 2. This table identifies the different features of those models. Models that possess
a certain feature have a check mark ()in the respective column. If a feature is not available
in the particular model, the column is left blank.
L-INX models with the router option have a CEA-709 router or a BACnet router,
respectively. The LINX-151 has both a CEA-709 router between FT and IP and a BACnet
router between MS/TP and IP.
