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-900) 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-900 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 900 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.
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
4.4). 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 8.3).
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),

LOYTEC electronics GmbH
L-INX/L-GATE User Manual 11 LOYTEC
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.
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 L ON M ARK 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,
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 12 LOYTEC
generating alarms over the L ON M ARK 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 infrastructure,
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 BTLcertified 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,
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 13 LOYTEC
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 infrastructure,
operation as a BBMD for a BACnet/IP network with the router option,
troubleshoot the MS/TP network with Wireshark remote packet capture (see Section
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 except the LGATE-900 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
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 14 LOYTEC device for using Modbus, configuring and using Modbus data points, refer to the Modbus
Chapter in the LINX Configurator User Manual [2].
1.6 KNX
In addition to the basic network technologies, some L-INX and L-GATE models can be
connected to KNX networks (see Section 1.10). To gain access to a KNX TP1 network, the
LKNX-300 interface has to be attached to the device for TP1 networks. All KNX-capable models support KNXnet/IP directly with their Ethernet interface.
The KNX interface allows creating KNX data points which can be used with the AST functions, the OPC server and also the PLC on the L-INX models. The device configuration can be imported from an ETS database export.
For more information on how to set up the device for using KNX, configuring and using
KNX data points, refer to the KNX Chapter in the LINX Configurator User Manual [2].
1.7 EnOcean
In addition to the basic network technologies, some L-INX and L-GATE models can
integrate EnOcean wireless devices (see Section 1.10). 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 1.10). 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 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
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 15 LOYTEC
directly to the L-INX using the LIOB-Connect feature (see Section 1.10). 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].
1.10 L-INX and L-GATE Models

2 What’s New in L-INX/L-GATE
LOYTEC
2.1 New in L-INX/L-GATE 6.1.0
This section describes the major changes and new features. For a full list of changes refer to the Readme file.
LSMI-804
The LSMI-804 interface is supported. This is a four-channel SMI interface connected to the
USB port of the LOYTEC device. It also contains four relays for SMI channel power-on functionality. This saves energy while the SMI bus is idle. For more information on SMI read the respective Chapters in the Device User Manual [1] and the LINX Configurator
User Manual [2].
Selective Backup and Restore
The backup and restore interface on the Web interface has been extended by content options. It is now possible to decide whether a created backup shall contains passwords, IP settings or historical data (trend logs, alarm logs). Also when restoring a backup archive it can be selected whether password and IP settings shall be accepted from the backup or not.
This makes it easier to replicate devices without scarifying the IP configuration and
password settings. An example is shown in Figure 1.
Figure 1: Backup and restore options on the Web UI.
L-STAT Configuration Backup
The Modbus commission Web UI has been extended to better support L-STAT devices.
Now it is possible to upload one or more L-STAT backup files and save them on disk.
Those L-STAT backup files can also be restored to L-STAT devices. The regular device backup now includes all L-STAT device backups as well.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 20 LOYTEC
Advanced WLAN Mesh Configuration
The WLAN Mesh configuration has been enhanced by a graphical floorplan editor as well as an online monitor of inter-link communication quality. This tool allows not only easier setup of a Mesh network but also simple troubleshooting by identifying radio bottleneck
between Mesh points (see Figure 2).
Figure 2: Mesh floorplan and online link quality monitor
Flexible Column Layout in Configurator
The Configurator now supports a flexible column layout in the data point list. It is possible to modify the column arrangement and add/remove columns as needed. This provides for better overview in situations where the default column layout misses important information.
The new Configure Columns dialog makes this possible.
Incremental Data Point Scan
The data point scanning engine of the Configurator has been extended to mark data points already used on the device and data points found in new scans. The last two columns Used
on Device and Last Scan of Figure 3 show an example and can be used to sort the list. This
way the data point configuration can be easily adapted to incremental changes of the scanned devices.
Figure 3: Example of an incremental data point scan
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 21 LOYTEC
LCD Interface
The user interface on the LCD display has been localized for the Chinese simplified and traditional language sets. The language can be selected from the main page and is switched immediately without a device reboot.
Another feature on the LCD display is the option to rotate the display 180 degrees. This is a useful setting, if the device is mounted upside down.
EnOcean VLD Profile Support
EnOcean devices that require variable-length data (VLD) profiles are now fully supported.
The respective device templates are provided by LOYTEC. In addition to new profiles, the teach-in process on the Web interface has been improved by dialog wizards that guide through bi-directional teach-in and assignment of transmission IDs.
2.2 New in L-INX/L-GATE 6.0.0
This section describes the major changes and new features. For a full list of changes refer to the Readme file.
New User Manual Structure
The L-INX/L-GATE User Manual has been split up into three parts: The L-INX/L-GATE
User Manual, which now covers the specific functions of the L-INX and L-GATE device models. The LINX Configurator User Manual is a common description for using the
Configurator software for the L-INX, L-GATE, L-ROC, L-IOB, and L-DALI product line.
And the LOYTEC Device User Manual covers hardware, Web interface, LCD display and operating interfaces topics common to all LOYTEC devices.
New Models and Combined Firmware
The new LROC-400 room controller models are now supported by the device firmware and in the LINX Configurator. The different device firmware images for LROC-10x, LIOB-
AIR, and LROC-400 have been integrated in one image for all L-ROC, L-INX, LIOB-AIR and L-GATE models.
SMI
A new protocol is now supported: SMI for controlling sunblinds over the Standardized
Motor Interface. All LOYTEC devices with an EXT port can now be extended by the
L-SMI interface and connect to an SMI bus. The LINX Configurator provides SMI device templates, which can be commissioned on the device Web interface. The Web interface supports manual address assignment, scanning for SMI devices and calibration. For more information on SMI read the respective Chapters in the Device User Manual [1] and the
LINX Configurator User Manual [2].
Flexible CSV Import/Export
The entire CSV import/export engine of the LINX Configurator has been revisited.
Previously special export options with fixed columns for CEA-709, Modbus, etc. have been replaced by a general CSV engine that is able to configure columns for any set of data point properties. Default property sets have been added, which can be modified by the user and saved for later use. The new CSV import/export allows modifying existing data point properties by batch edit in Excel or creating new data points. The property sets can be
viewed and modifed in a comfortable export editor (see Figure 4). The new engine also
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 22 LOYTEC integrates CSV data point templates. Learn more about this flexible import/export mechanism in the LINX Configurator User Manual [2].
Figure 4: CSV export dialog with configurable columns.
Override Function for Data Points
The data point model in LOYTEC devices has been extended with a manual override function. On the Web interface and on the LCD display data point values can be overridden to manual values. If an override value is set, the running control logic no longer affects the data point value, neither does network communication. The override value is in effect until it is removed again by the user.
Figure 5: Overriding a data point on the Web interface.
WLAN Mesh Configuration
The Mesh Point mode has been extended by a whitelist function. This allows configuration of a Mesh network with up to 32 nodes. The whitelist contains all mesh point IDs that may contact each other. In order to make configuration of the mesh network easier, the Quick
Wireless Setup has been added, which allows a first mesh setup in only a few steps. For optimizing the whitelist the Web interface offers a graphical editor, which makes changes quick and simple. On device models with an LCD display the wireless setup can also be completed using the jog dial. For more information on how to set up a Mesh network please refer to the respective Sections of the LOYTEC Device User Manual [1].
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 23 LOYTEC
Alarm Messages
The length of alarm messages has been extended to 250. This increased length comes in combination with a new %{path} variable placeholder that can identify the data point path in alarm messages. This is beneficial for mass-engineering alarm conditions on data points that have the same name but are located in different path locations. Alarm logs have also been updated to support the new maximum legnth. BACnet now supports the Event
Message Texts property of an alarmed object, which allows retrieving the messages also after a reboot of an alarm client. And analog alarm conditions have been extended to specify a high limit and a low limit alarm message.
Trend Logs
The generic trend logs have been extended to support recording string values. These trends can be operated as polled, COV or triggered. These trend logs can be beneficial to record arbitrary messages The string recording is currently limited to generic trend logs only.
New E-Mail Placeholders
E-Mail configuration has become even more flexible by adding new variable placeholders.
The variable placeholders can be augmented by name, description and path specifiers that expand to the respective information in the e-mail. A new date format specifier allows for readable timestamps and the %{last_timestamp} variable expands to the time the last e-mail was transmitted.
BTL Testplan 12 Certified
The BACnet certification of all BACnet models has been updated to comply with protocol revision 12. All new device models are now BTL certified.
2.3 New in L-INX/L-GATE 5.3.0
This section describes the major changes and new features. For a full list of changes refer to the Readme file.
New L-INX and L-GATE Models
The new L-INX and L-GATE models in the small enclosure are now supported. Equipped with dual Ethernet, a built-in firewall and LCD display, these new models serve as a plug-in replacement for the older devices. Existing data point configurations and device backups can be used without modification. Only logiCAD programs need to be re-compiled for the new hardware resource. In addition, the new models also support L-IOB connect, wireless technologies and KNX.
Extended Support for U.S. Units
An extended support for U.S. units has been built into LOYTEC devices. A device can now be configured to run either in the SI or the U.S. unit system by defining SI and U.S. units
per data point as shown in Figure 6. When configured for U.S. units, all data points and
L-IOB I/Os process values in the respective U.S. units. This includes the Web UI, the OPC server, the parameter file, global connections, and logiCAD programs. Also the
Configurator displays values in U.S. units and conversions are done automatically. A device can even be switched from one unit system to the other. In this case all persistent parameters are reset to their default values in the chosen unit system. A system register shows the currently running unit system. This makes it easy to entirely engineer a device in U.S. units or build devices that can be configured for either European or U.S. markets and meet local
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 24 LOYTEC requirements at the same time. For more information on units please refer to the LINX
Configurator User Manual [2].
Figure 6: Configuration of SI and U.S. units on a data point
OPC Client
L-INX and L-GATE devices are extended by their own OPC client technology. Using the
OPC client you are able to integrate other LOYTEC devices simply by importing the data point configuration of their OPC servers. This way an L-DALI device can be added to a
L-INX configuration in a few steps. The OPC client can also take advantage of the commission later feature by using the Web UI in order to assign OPC server URLs at the time of device commissioning. Even the base path to imported OPC tags can be replaced.
This way sub-configurations can be imported to save OPC client tags and be re-assigned later. Learn more about the OPC client function in the LINX Configurator User Manual [2].
Forward Delay in Connections
For applications that require staggered start/stop and randomization, the device implements a configurable forward delay in local and global connections. All receive data point items can be configured with a delay. A received value is written to the data point after the delay expires. The delay can be a fixed time or a time interval, in which the actual delay is randomized. With a resolution of 0.1 seconds the total delay can be up to 100 minutes.
Learn more about forward delay in the LINX Configurator User Manual [2].
Auto-Generate and Connect
The auto-connect feature has been extended:
Support %{folder_descr} as a placeholder in auto-generate templates. This evaluates the description property of the parent folder.
Generate into existing connections. Epecially when auto-generating the same source data points to different technologies, the same connections are used. This makes it easier to manage auto-generated local connections.
Enhanced Structure Support on the Web UI
The display of data point structures has been improved on the Web UI. The data point listing shows a textual short version of the structured value instead of a hexadecimal Byte buffer. Also CEA-709 structures of NVs without sub-data points are displayed and can be edited.
Project Documentation
A new feature on the device is a Web UI for creating and viewing project documentation on the device. The documentation editor requires admin rights and allows storing files on the device or creating documentation links as URLs. Both items can be viewed by guest users.
Examples include storing cabling plans as PDF or adding links to a Web site containing manuals, plans or other useful project documentation. Consult the LOYTEC Device User
Manual [1] to learn more about project documentation on the device.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 25 LOYTEC
LWEB-802 Application on Device
The L-INX and L-GATE device now come with a pre-installed version of the LWEB-802 application. This enables out-of-the-box L-WEB applications on sites without Internet access. An enhanced Web UI also allows installing a specific version of the LWEB-802 application, which overrides the pre-installed one. As a default, the Internet version is still available. To learn more on how to configure the L-WEB application refer to the LOYTEC
Device User Manual [1].
BACnet
All previously extended BACnet features and new features have been BTL-certified in the
5.X firmware series. New features include:
BACnet object names can be made writeable. With this new option the user can create data point configurations with generic object names and assign location-specific names later in his OWS.
BACnet simple value objects are now supported. The user can create Large Analog
Value, Signed Integer Value, Unsigned Integer Value, Character String Value and
Octet String Value objects as needed. Also auto-connect supports these new object types.
For Trend Log objects, the properties Notify_Type, Event_Enable, Notification_Class can be pre-configured in the data point configuration.
User-defined Serial Protocols in logiCAD
A new logiCAD service block has been introduced, which allows implementation of generic serial protocols. The ‘SerialComm’ service block can receive and transmit strings from and to a serial port using start frame and end frame delimiting characters. A logical bus number is assigned to the service block, which can be selected as a custom serial protocol on the
port configuration Web UI as shown in Figure 7. Please read Section 6.6.10 to learn more
about using the ‘SerialComm’ block.
Figure 7: Selecting a custom logiCAD serial protocol.
Data Point Creation from CSV Lists
The Configurator implements a new data point template CSV import feature, which can be used by external tools to generate a list of data points. Each line in this CSV references a data point template file that describes all properties of the data point. The CSV supplies name, description and path of the data point to be created. Additionally, data points can be automatically scheduled and trended. Learn more about data point templates in the LINX
Configurator User Manual [2].
KNX Protocol Analyzer
Devices that support the KNX protocol now have a built-in protocol analyzer. It can be accessed through the KNX statistics Web interface and allows starting, stopping and storing protocol logs on any of the KNX interfaces. Protocol logs can be loaded from the device
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 26 LOYTEC and stored on the PC either in CSV or in XML format. The XML format can be opened in the ETS protocol viewer. Learn more about the KNX protocol analyzer in the KNX Chapter of the LOYTEC Device User Manual [1]. ekey Fingerprint Readers
LOYTEC devices can now be used to build applications with biometric access control
(fingerprints). The ekey fingerprint reader devices can be attached to the RS-485 port. Users and fingers can be enrolled and grant or deny access when swiping the finger over a reader.
User groups can be implemented and distributed over reader devices. Learn more about ekey fingerprint reader support in the ekey Chapter of the LOYTEC Device User Manual
[1].
2.4 New in L-INX/L-GATE 5.1.0
This section describes the major changes and new features. For a full list of changes refer to the Readme file.
Dual-Ethernet with Separate Networks
L-INX and L-GATE models with two Ethernet interfaces can now be configured to work with separate and isolated IP networks. For example, one Ethernet interface can be accessed over HTTPS from a WAN connected to Ethernet 2 while the building network services are running locally on the LAN connected to Ethernet 1. For configuration the device provides separate Ethernet tabs in the port configuration, which allow selecting the offered services
on each interface. The example in Figure 8 shows a WAN interface with HTTPS and OPC
UA only, while BACnet/IP or CEA-709 over IP are still bound to Ethernet 1 (LAN).
Another use case for this feature is operating a gateway between otherwise entirely isolated building networks, e.g. BACnet/IP on Ethernet 1 and KNXnet/IP on Ethernet 2.
Figure 8: New Ethernet 2 (WAN) tab
WLAN Interface
In combination with the external LWLAN-800 interface, the device provides new interface tabs for wireless IP networks. Similar to the second Ethernet interface, one can choose which protocols are available on the wireless network. The wireless interface can be configured as a WLAN client, access point or mesh node. Using the latter, a wireless mesh network of LOYTEC devices can be built. Please refer to the LOYTEC Device User
Manual [1] to learn more about the WLAN interface.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 27 LOYTEC
EnOcean
The EnOcean technology is now supported by the L-INX and L-GATE devices. Together with the external LENO-800 interface, EnOcean sensors and actuators can be easily integrated. LENO-800 interfaces are available for European, U.S. and Japanese frequency bands. Data point configurations for the EnOcean technology are built using EnOcean device templates. The actual assignment of physical devices is done later in the teach-in process over the Web UI. For more information on the EnOcean technology please refer to
EnOcean Chapter of the LOYTEC Device User Manual [1].
SNMP
For accessing vital operational data in standard IT equipment, L-INX and L-GATE devices offer an SNMP management base (MIB). All system registers and OPC-exposed data points are available in that MIB. The MIB file can be downloaded from the device and imported in the SNMP management tool. Alarms on the device can be exposed as SNMP traps. For more information on configuring and using SNMP with a LOYTEC device please refer to the LOYTEC Device User Manual [1].
Online Commissioning
The Web interface of the device now provides an online commissioning tool for the respective networking technologies. Using this tool, data point configurations can be created based on placeholder devices, which are marked to be commissioned later. The necessary addressing information can be assigned later on the Web interface by scanning for devices online or be entered manually. Device replacement is also possible in the commissioning Web interface without the need to edit devices in the data point configuration. For more information on the commissioning Web UI please refer to the
LOYTEC Device User Manual [1].
Favorites
Enhancements for using favorites include engineering units, active/inactive texts, multi-state texts and value persistency for unlinked favorites. A new feature are structured favorites.
For example, the structure of a SNVT_switch may now be created as a favorite. The toplevel part of a structured favorite can be linked to a structured data point of the same type.
Alternatively, the individual member elements of a structured favorite can be linked to other, individual data points. This way, one is able to create a structured favorite, that can be linked directly to a matching SNVT or to separate BACnet objects..
Web Interface
The Web interface of the device offers a number of new features:
A new device info page provides a quick overview of all relevant operational parameters, such as CPU load, active protocols, time synchronization and many more.
The trend log configuration on the Web UI now also provides a preview tab, which shows a chart of the trend log data. The trend chart allows zoom, scrolling and hiding
specific data curves, as shown in Figure 9.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 28 LOYTEC
Figure 9: New trend chart on the Web UI
Scheduler
The scheduler objects have been extended by the following new features:
Color support in BACnet and generic schedulers allows consistent assignment and display of preset colors in L-WEB, L-VIS and the Configurator scheduler UIs.
Event auto-prune removes passed events, if the capacity of exception events in a scheduler gets low.
The scheduler default for L ON M ARK and generic schedulers is extended by a “silent” mode. In this mode the scheduler becomes inactive as soon as the last event is withdrawn. This mode can be used in event-driven scheduler models.
Generic schedulers allow specifying an existing value preset as the schedule default.
L ON M ARK and BACnet schedulers try identifying a matching preset name from the schedule default value.
5000 BACnet Client Maps and Dynamic Polling
The number of BACnet client mappings on the L-INX has been increased to 5000. This has become possible with the use of strict on-demand dynamic polling on the device. This means any data point configured for polling (client mappings, external NVs, Modbus, etc.) will start polling only when it is actually used, i.e. displayed on L-WEB, the data point Web interface or used by a trend log. This reduces the required network bandwidth.
1000 Trended Data Points in LINX-12x/15x/22x/LGATE-95x
The bigger L-INX and L-GATE devices now allow a total of 1000 trended data points distributed among the 512 trend logs. This limit can be exploited when trending two or more data points in a generic trend log.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 29 LOYTEC
Alarm Server Ack-All Data Point
Alarm servers now provide a special ackAll property data point. When writing TRUE on that data point all currently active alarms on the alarm server are acknowledged.
Format Strings in E-Mails
Data point variables used in e-mail templates can now use format strings to specify their numeric appearance in the e-mail text.
Output NVs with Integrated Feedback
Output network variables (NVs) are used to send updates to remote nodes. In order to poll back the actual value of the remote variable, a feedback data point had to be created for the output NV. Now changing the direction on the NV from output to value, an integrated feedback function is activated without the need for an extra data point. This becomes especially useful in data point templates.
Modbus and M-Bus Templates
Modbus and M-Bus device templates offer some new features that boost productivity:
Templates can now contain definitions of pollgroups and other type resources used by
Modbus data points.
Templates can now store a folder hierarchy.
2.5 New in L-INX/L-GATE 5.0.0
This section describes the major changes and new features. For a full list of changes refer to the Readme file.
Generic Scheduler
Generic schedulers – like generic trends and alarms – can now be created, that are neither
CEA-709 nor BACnet objects. Generic schedulers appear next to the generic alarm folder and are ready-to-use on any device. This is beneficial for creating technology-independent applications. Generic schedulers can write to any technology as well as data point favorites and are the ideal solution, if configured via LWEB-900 only. For more information on creating generic schedulers refer to the LINX Configurator User Manual [2].
Optimum Start for Schedulers
Up to now, optimum start was limited to using a SNVT_tod_event in a CEA-709 scheduler.
Now all schedulers (including BACnet and generic schedulers) support timeToNext and nextState data points for implementing optimum start algorithms also for those technologies. Schedulers are extended by property relations, which offer the time to the next state in minutes and the next state in data points. Also, the enable, enableFb (feedback), and presetName information is available as property relations.
The BACnet scheduler object also has custom properties that expose time to next state and next state to BACnet. If standard BACnet objects are required, the property relations can be
linked to any matching BACnet server object as shown in Figure 10 (BV_nextState,
AV_timeToNext).
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 30 LOYTEC
Figure 10: BACnet scheduler with next state data points.
Favorites
Favorites have been vastly extended to be compatible with all uses that were previously only possible for regular data points. Favorites can now be trended, can have an alarm condition (reporting to a generic alarm server), and be scheduled. Historic filters can be applied to favorites. Favorites can also be used in e-mail templates, math objects and connections like any other data point. Furthermore, it is possible to link favorites to property relations and vice versa, e.g. link a favorite directly to a historic filter data point.
Historic Filters
Historic filters have been extended by a generic delta calculation between any of the defined filter items or the current value. This way, it is no longer necessary to create a separate math object to calculate the consumption of the previous month. Also, a definition for “last day of month” has been added to the monthly period.
256 Trend Logs on LINX-10x/11x/20x/21x/LGATE-900
The smaller L-INX and L-GATE devices are now extended from 100 trend logs to 256 trend logs at a total of 256 trended data points. This is beneficial for native BACnet trend logs, which allow only one data point per trend log object. The increase comes at the cost of available log rate, which is reduced from 121,050 to 60,525 records per hour, once more than 100 trend log objects are created. This is, however, still sufficient for 256 energy trends at 1 minute log interval each.
Web Interface
The Web interface of the device offers a number of new features:
Live update of values in the data point list. This allows monitoring values without repeated pressing of reload. Data point structures can be expanded or collapsed for better overview.
Breadcrumb navigation has been added to the data point list. This gives faster access to sub-folders.
A new firmware upgrade menu on the Web interface allows online checking for firmware updates and upgrading by selecting a local firmware file. All this is possible without starting the Configurator.
The trend overview page displays current trend log states and provides controls for easy trend data upload in CSV format.
Data Point Polling
The receive timeout on input and value data points has been generalized. A receive timeout can now be defined on all technologies for input and value data points. Writing updates to those data points from any source (e.g. a global connection) resets the receive timeout.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual
31 LOYTEC
Background polling can be enabled in the project settings, which allows a slow polling of all data points even if no pollcycle or dynamic polling has been activated on those data points..
OPC UA Server
The OPC server on the devices, which support security, has been extended by an OPC UA server. This supports the OPC UA binary protocol and exposes the same OPC tags as the well-known OPC XML-DA server. In addition OPC UA offers superior security features as well as slimmer data transfers. For more information on the OPC UA server please refer to the LOYTEC Device User Manual [1].
BACnet
All previously extended BACnet features and new features have been BTL-certified in the
5.X firmware series. New features include:
Intrinsic alarming for the Accumulator object.
Option to keep OWS settings in BACnet properties also after a new configuration has been downloaded.
BACnet naming rules can now freely define how data point names are constructed out of scanned BACnet information.
Conversion to Value Data Points
Firmware versions since 4.9.0 support value data points. The default behavior of the
Configurator can be controlled in the project settings. This defines whether new value data points or the old “_Read/_Write” data point combinations shall be created. When using templates in L-WEB or L-VIS it is often an all-or-nothing approach, a mixture is not practical.
For making the transition in old projects to value data points, the Configurator now offers a conversion tool. Multi-select old read/write data points and choose the item Convert to
value from the data point context menu. This converts the selected data points to the new value data points, leaving the IDs, default values and data point usages intact.
Application Objects
Application objects such as math objects, e-mail templates, and alarm logs can now be organized in folders. Copy and paste of application objects between Configurators has been improved. Math objects now allow single constants and single variable assignments, such as
“=5” or “=v1”. Input variables can be configured to trigger a new calculation or not.
Configurator Usability
The folder tree of the data point manager has been brought to state-of-the-art user concepts such as multi-select, drag-and-drop of folders, moving folders, deleting multiple folders and their contents. A name filter can be applied to quickly find folders in the folder tree.
The property tab has been extended by a property name filter. This makes it easy to find the desired property by typing a sub-string of its name in the filter. For a detailed description on the data point properties refer to the LINX Configurator User Manual [2].
Data point link navigation has been made easy by using a Go to data point context menu and speed button everywhere data point references are displayed. A data point usage report dialog shows all references to the selected data point and allows jumping to selected objects.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 32 LOYTEC
The new PLC conflicts tab shows all PLC write conflicts with other write usage of data points such as math objects, connection receivers, etc., while editing the project. This allows finding problems prior to the configuration download. The conflicts tab also provides easy navigation to data points listed as problematic. For more information refer to
Modbus and M-Bus Templates
Modbus and M-Bus device templates offer some new features that boost productivity:

After that, the CNIP LED flashes orange six times if the wink command was received on the IP channel or the CEA-709 activity LED flashes orange six times if the wink command was received on the CEA-709 channel. After that the device’s LEDs resume their normal behavior.
4.4.16 Network Diagnostics
The CEA-709 device provides simple network diagnostics via its CEA-709 activity LED:
If the LED does not light up at all, this port is not connected to any network segment or the connected network segment currently shows no traffic.
If the LED is flashing green, the network segment connected to this port is ok.
If the LED is flashing red, a potential problem exists on the network segment connected to this port. This state is referred to as overload condition.
A port overload condition occurs if
the average bandwidth utilization of this port was higher than 70 %, or
the collision rate was higher than 5 %, or
more than 15 % CRC errors have occurred on a port with a power-line transceiver, or more than 5 % on a port with a transceiver other than power-line, or
the device was not able to process all available messages.
For a deeper analysis of the reason for the overload condition, it is recommended to use a protocol analyzer (e.g., LOYTEC’s LPA) or a similar tool. The exact reason of the overload condition can also be determined with the LSD Tool.
4.5 Status Button
The L-INX models 10X, 11X, 20X, 21X and the LGATE-900 are equipped with a status button (see product installation sheet). When pressing the status button shortly during normal operation of the device, it sends a “Service Pin Message” on the active CEA-709 network port (FT or CEA-852) and a BACnet “I Am” message on all active BACnet data link layers. As an alternative to pressing the status button, a service pin message can be sent via the device info page on the Web interface (see LOYTEC Device User Manual [1]).
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 54 LOYTEC
The status button can also be used to switch the device back to factory default state. Press the service button and power-cycle the device. Keep the button pressed until the port LEDs illuminate orange permanently. Release the button within five seconds from that time on to reset the device to factory defaults. Alternatively, the device can be switched back to factory
defaults over the console UI (see Section 8.2.2).
4.5.1 Resetting Forwarding Tables
This function is available on CEA-709 models with the router option. In order to reset the forwarding tables of the device’s router, the status button needs to be pressed for at least 20 seconds during normal operation of the device. Resetting forwarding tables means:
Resetting the CEA-709 transceiver to the standard values.
Setting all ports to unconfigured.
Clearing the group forwarding, the subnet/node forwarding and the router domain table when used in smart switch mode.
Clearing the device status and statistic data.
But does not clear the IP address, the CEA-852 configuration settings, and the data point configuration.
All this is done when the button is released. Afterwards a reset is performed to let the changes take effect.
Important:
Important:
If the L-INX is moved from one location to another or if major changes to the configuration of the network are made, it is recommended to reset the configuration to factory defaults.
Wait at least 30 seconds after power-up of the device before pressing the Status Button to ensure that the device has booted properly!
4.6 DIP Switch Settings
The DIP switch assignment for the device is shown in Table 8. Please leave all switches at
default state. Note, that the L-INX models 12X, 15X, 22X and the LGATE-95X do not have DIP switches.

5 Concepts
LOYTEC
5.1 Universal Gateway
The operating principle of a universal gateway is to connect data points of one network technology to data points of another technology. This is the primary function of the
L-GATE product family. Gateway function are, however, also available in the L-INX family.
Data points in the CEA-709 network are known as network variables (NVs). Data points in the BACnet technology are known as BACnet server objects. They have a specific type (e.g. analog input or binary output) and a set of properties, which describe the data point more closely. The actual value is stored in the “Present_Value”. For more information on the mentioned technologies refer to the LINX Configurator User Manual [2].
The typical task in configuring the universal gateway consists of the following steps:
1. Selecting the data points of the network to be mapped (e.g., select the NVs in the
CEA-709 network nodes or create new NVs)
2. Select or create matching counterparts of the other technology (e.g., create matching
BACnet objects)
3. Create connections between the data points (e.g. connect NVs and BACnet objects).
The connection is the central part of the gateway functionality. It defines, which data points are mapped to which data points. Refer to the Connections Section in the LINX
Configurator User Manual [2] for more information.
5.2 Data Point Configuration
Data points are part of the fundamental device concept to model process data. A data point is the basic input/output element on the device. Each data point has a value, a data type, a direction, and a set of meta-data describing the value in a semantic context. Each data point also has a name and a description. The entire set of data points is organized in a hierarchy using a folder structure. Folders can be created as needed and have a folder name and description.
The direction of a data point is defined as the “network view” of the data flow. This means, an input data point obtains data from the network. An output data point sends data to the network. This is an important convention to remember as different technologies may define other direction semantics. If a data point can both receive and send data on the network, its direction is set to value, indicating no explicit network data flow.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 57 LOYTEC
The device provides a Web interface for displaying and modifying data point values (see
Figure 35). Data points that are structures contain their structure members as sub-data points
beneath them. Data point values are typically written by the controller or by the network.
For testing purposes the values can also be manually overridden (Set Override). More information on the data point Web interface can be found in the LOYTEC Device User
Manual [1]. For a comprehensive description of the data point configuration on the device please refer to the LINX Configurator User Manual [2].
Figure 35: Data points on the Web interface.
5.3 IEC61131 Variables
IEC61131 variables are used to exchange data with the IEC61131 program. These variables are represented in the data point configuration as register data points and can be connected to other data points, e.g. to CEA-709 NV points, via data point connections.
In contrast to CEA-709 or BACnet variables, IEC61131 variables are always represented as single data point. In case of scalar values (representing CEA-709 scalar or enumeration types) one of the following basic data types might be used:
Double: A register of base type double is represented by an analog data point. It can hold any scalar value. No specific scaling factors apply.
Signed Integer: A register of base type signed integer is represented by a multi-state data point. This register can hold a set of discrete states, each identified by a signed stats ID.
Boolean: A register of base type boolean is represented by a binary data point. This register can hold a Boolean value.
Structured IEC61131 variables, representing for example structured NVs, or customer defined IEC61131 structures, are stored as user type:
User: A user data point contains un-interpreted, user-defined data. The data is stored as a byte array. A user data point does not include any other meta-data. This type of data point also serves as a container for otherwise structured data points and represents the entire data structure. User data points can only be connected to other user data points of the same data length.

LOYTEC
To design the IEC61131 program which should run on the L-INX device, the graphical programming tool logiCAD is required. The tool allows creating IEC61131 programs using various IEC61131 programming languages. It offers additional features downloading and debugging of the created program.
In addition to logiCAD, the L-INX Configurator necessary to create an appropriate data point configuration in the automation server. The usage of logiCAD itself is beyond the scope of this manual. Please refer to the logiCAD online help in case of additional questions.
6.1 Overview
The PLC in the L-INX device is intended to perform IEC61131 programs operating on
IEC61131 data points. The operating principle is to connect IEC61131 data points to data
points derived from CEA-709, BACnet or LIOB network. Figure 36 depicts the usage of
data points for IEC61131 programs at the example of using CEA-709 network variables.

Alternatively, data points can also be directly exposed as IEC61131 variables. The data points provide a PLC check box for this purpose. In this use case, not special IEC61131 data points are created and no connections are necessary.
6.2 Installing logiCAD
For developing IEC61131 programs with logiCAD the following components must be installed:
1. L-logiCAD setup package. This package installs the logiCAD software, which is needed to design PLC programs for the L-INX device.
2. L-INX Configurator. This software is required to configure the L-INX device to provide the necessary data points to the PLC and integrate the device into the network.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 59 LOYTEC
3. logiCAD license for using logiCAD on the PC. The license is available as a softlock version or as a hardlock version with a USB dongle. On virtual machines it is mandatory to use the hardlock license. How to obtain and install the license is described in this Section.
The L-logiCAD installer installs the IEC61131 programming environment logiCAD and all
L-INX related software packages. These packages include the template project for the
LINX, the required software to build IEC61131 programs for the L-INX device, and required extensions to interface to CEA-709 networks. Follow the instructions of the installer to install logiCAD for the L-INX.
The language for the logiCAD user interfaces can be set to German or English using the administration folder of the logiCAD control center. The logiCAD control center can be started from the Windows start menu.
6.2.1 Softlock License
The license to run a copy of logiCAD on any PC is based on a softlock license. In case the original softlock license file was generated for an older L-logiCAD version, the software will request an update signature key for the new L-logiCAD installation. This signature key can be found in the file ‘logicad_Readme.txt’ that is located in the installation directory of the L-logiCAD software.
To obtain and install a new license start logiCAD. The product activation dialog will appear
as shown in Figure 37. In this dialog press the button Download Softlock License.
Important! When using Windows7 start logiCAD as administrator in order to allow the script read the computer number code. If there are x's in the code, the code was not read by the script.
Figure 37: logiCAD Product Activation
Enter the license data provided with the product information on the Web site form as shown
in Figure 38. Fill in the SL-number and Licensing Code from your L-LOGICAD
registration form and click on Download License File. Save the license file on your computer or have it e-mailed to you.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 60 LOYTEC
Figure 38: logiCAD softlock license Web form.
Then install the license using the Install Softlock License button in the product activation
dialog as indicated in Figure 39.
Figure 39: logiCAD softlock installation.
A file requestor dialog opens. Locate the downloaded license file (logicad.lf) and click
Open. Finally click Close in the product activation dialog and start logiCAD again. The softlock license is now activated.
6.2.2 Hardlock License
The hardlock license is needed to run a copy of logiCAD in a virtual machine on the PC. It needs to be puchased separately as L-LODICAD-USB and is distributed as a USB hardlock key of type ‘CodeMeter’. If no driver for this type of hardlock is already installed on the
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 61 LOYTEC
PC, install the hardlock driver provided on the LOYTEC website. It can be found in
Support Download and the product selection for L-LOGICAD. After the driver installation has completed, plug in the USB key. It must be recognized as a mass storage device (the details on it show the location ‘CodeMeter-Stick’). When starting logiCAD it recognizes the hardlock automatically.
If the driver installation failed, or the USB key was not detected or connected, the window
shown in Figure 40 will be shown when logiCAD is started. In this case plug in the hardlock
stick, wait for Windows to recognize it and then click Find Dongle.
Note:
Figure 40: logiCAD Product Activation with Hardlock logiCAD checks frequently if the USB key is present. When unplugging the USB key, even if logiCAD was successfully started, all major features are automatically disabled. But there is no additional message for the user!
6.3 IEC61131 Project Files
In the L-INX Configurator select the LogiCAD Files tab to attach an IEC61131 program
and a logiCAD project to the L-INX project. The tab is shown in Figure 41.
If there is an IEC61131 program attached to the project, every time a new configuration is downloaded to the device, the L-INX Configurator asks, if the attached program should be downloaded as well. This way, no logiCAD is required to download a suitable IEC61131 program in a separate step. The project designed in the L-INX Configurator can hold all necessary information to set up a running device:
IEC61131 data point configuration,
Data point configuration in the LINX,
Required connections,
IEC61131 program.
The logiCAD project directory can also be attached to the L-INX configuration file, in order to include the logiCAD project sources from which the program was compiled.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 62 LOYTEC
Figure 41: IEC61131 Project Files.
To attach an IEC61131 program or a logiCAD project select the file/folder to attach. The selected data will be attached automatically the project. It can be restored to disk by pressing the Restore to Disk button. During the development process the attached data may change several times. To update the attached data, located on the before provided path, press the Refresh button.
Every time a logiCAD project is successfully compiled, the file MBRTCode.so, the compiled IEC61131 program, is copied to the public directory of the device resource for which the program was compiled. Select this file to attach it to the project of the
Configurator. Note that the time and date of the file indicates the time of the last code generation. If logiCAD is not able to build a new program, the old file will not be deleted.
The project will be scanned for device resources and the available devices will be listed in the dropdown box called Device Config. Select the desired device and press the button
Attach Program to automatically attach the correct MBRTCode.so file.
6.4 Working with logiCAD
This section provides all necessary background information how to use the L-INX with logiCAD. For using the L-INX with logiCAD, a predefined project template for the L-INX must be used. Hence, when creating a new project, select the project template “Project for
LINX-110”, see Figure 42. For additional information how to create, delete and manage
projects please refer to the logiCAD online help.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 63 LOYTEC
Figure 42: L-INX specific extensions
Figure 42 shows the standard project for the L-INX including all LINX-specific extensions
for logiCAD. It shows the structure window showing the project structure on the left, an empty working area top right and the Error-state viewer on the bottom right side.
The structure window offers interfaces to the following features:
1. The folder Functionplans holds all the program types created within logiCAD.
‘Plan_1’ is the default plan to start with.
2. The folder LOYTEC/LINX-110 represents the LINX-110 device. The folder
LOYTEC represents a configuration containing one LINX-110 resource; please refer to the logiCAD online help for details. To run a program, located in the folder
Functionplans, a program instance of the corresponding function plan must be created.
In the standard LINX-110 template a program instance of the ‘Plan_1’ is already defined. To be able to transfer IEC61131 variables from the L-INX device to the
IEC61131 program a global variables object within the LINX-110 folder is required,
see Section 6.4.1 for details.
3. LogiCAD operates on variable types standardized in the IEC61131 standard. Look for
“Elementary and Generic Data Types” within the logiCAD online help to get information about the available data types. For those L-INX devices, which are intended to operate on structured NVs, appropriate type definitions for the NVs are required. These definitions are inside the folder CEA-709_Types. Additional NVs must be converted to data types that can be processed by logiCAD. Therefore
Technology Converters are supplied with the L-INX project, which perform this
conversion. See Section 6.4.3 for details.
blocks are required. These blocks are located within the Loytec_Support directory.
All LINX-specific add-ons are provided using function blocks. Hence, in the following, all samples are based on designs using function blocks.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 64 LOYTEC
6.4.1 Managing Variables
On a function plan, three basic types of variables may be created using the tabs shown below the function plan sheet:
VAR: Variables created on this tab will be visible only to the logic designed on this group of sheets. It will not be accessible to any other programs or to any function blocks which are used in this program. It is similar to a ‘static’ variable declaration in a
C code function.
VAR GLOBAL: Variables declared here will be accessible to the entire program, including any function blocks which are called by the program. Function blocks which need to reference this variable need to have a suitable declaration of an external variable (see next point). This declaration is similar to a ‘static’ declaration of a C variable outside a function, which will be visible to all functions inside the C code module, but not visible to other modules.
VAR EXTERNAL: Variables declared in this list will be treated as open references to a global variable which exists somewhere in the scope of the device on which the program will be executed. This means that a global variable needs to be declared on the device resource, which will be available to all programs running on the device. If the physical address parameter of the variable is set to %I, %O, or %M, the variable will be handed down to the I/O driver of the L-INX for processing. If a suitable IEC61131 variable exists in the data point configuration of the device, its value will be forwarded by the I/O driver between the PLC variable and the data point. If no physical address is set, the variable will only be visible to the PLC programs but not to the I/O driver, which may be used to exchange data between PLC tasks.
The basic data flow between the CEA709 network (or BACnet and other technologies) and
the PLC program is depicted in Figure 43.

The place where global variables are created on the device is shown in Figure 44.
Figure 44: Global Variables Object
When starting a new project, no global variables object is available; it must be created before compiling the IEC61131 application. The global variables object is created automatically by the LINX Configurator when exporting variables to logiCAD.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 65 LOYTEC
Figure 45: Variables defined in global variables object
Figure 45 shows the contents of a sample global variables object. As shown a global
variable is defined by the fields name, declaration and phys.addr.:
Name: The name of a global variable must be unique. The name is used from the IO driver to identify the global variable and from the L-INX Configurator to generate the corresponding IEC61131 data points.
Declaration: Here the type of the global variable is defined.
Phys.Addr.: The IO driver needs to know the data flow direction to be able to update variables. The direction is defined by adding %I for an input variable, %O for an output variable and %M for a marker (input and output). If the address is empty, the I/O driver will not handle the variable, but it may still be used by the tasks running on the device.
Important: Only ASCII characters can be used for naming the global variables.
6.4.2 Build and Download the IEC61131 Program
IEC61131 programs, designed using logiCAD, must be cross compiled in order to run on the L-INX device. The prerequisite to compile an IEC61131 program are as follows:
A program instance with associated program type
A corresponding global variables object
Right click on the LINX-110 resource, see Figure 44, and select Code Generation. Please
refer to the logiCAD online help for the meaning of the options. Take care about the option
breakpoint support, see section 6.4.5 for details.
After successfully finished code generation, the IEC61131 application can be downloaded to the LINX-110. Right click on the LINX-110 resource and select download.
The IEC61131 program can be downloaded to the LINX-110 device via TCP/IP, CEA-709 and RS232:
TCP/IP: Enter the IP address of the LINX-110 device. Do not change the default communication port (2048). This is the easiest and fastest way to connect to the device.
CEA-709: Select the network interface to use and fill out all other fields, see Figure 46.
Alternatively, select the network interface and press Auto-detect via Service-Pin. Then press the service pin on the LINX-110 device. Note that this connection method requires an installed LOYTEC network interface.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 66 LOYTEC
Figure 46: Connect via CEA-709
Important: To be able to communicate with the LINX-110 device via CEA709 the LINX-110 must be commissioned.
RS232: To connect via RS232 select LOYTEC RS232 as Driver and LOYTEC as transmission protocol. All other values are set correctly per default.
6.4.3 Usage of NVs, Technology Converters
To used CEA-709 variables the content of the NVs must be converted to IEC61131 compliant data types. Look for “Elementary and Generic Data Types” within the logiCAD online help to get information about the available data types. Technology Converters are used to perform the transformation from CEA-709 data types to IEC61131 data types. All
Technology Converters are summarized in the subfolder CEA709_Conv located in the
StandardLibs folder.
Depending on the type of the NV there are three different ways to use the NV within
IEC61131 programs:
Simple NVs that hold only one scalar value, e.g. SNVT_amp:
Those kinds on NVs are represented as IEC61131 REAL values within logiCAD.
There is no additional conversion necessary. Figure 58 shows an example program
for scalar data types.
Simple NVs based on an enumeration, e.g. SNVT_date_day:
The active identifier of the enumeration is represented as Boolean value. When using NVs based on enumerations, Enumeration Converters are used to identify the current state. There are two kinds of Enumeration Converters. First, the
Enumeration Converters that convert the enumeration types to Boolean types, grouped in the folder Convert from CEA709_Enums. Second, the Enumeration
Converters that converts several Boolean inputs to an enumeration type, grouped in the folder Convert to CEA709_Enums.
Structured NVs that consists of a number of fields, e.g. SNVT_switch:
On structured NVs two tasks must be performed by the Technology Converters.
First the structure of the NV is mapped to IEC61131 conform data types. Second, if necessary scaling factors are applied. Similar to the Enumeration Converters, the
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 67 LOYTEC
Technology Converters are split up into two subfolders. The first one, which converts the NV into IEC61131 compliant data types, is located in the folder
From_CEA709_Types. Technology Converters to set up NVs based on
IEC61131 data types are grouped in the folder To_CEA709_Types.
Figure 47 shows the three possibilities how to use NVs within an IEC61131 program.
Figure 47: Usage of NVs
If a structured NV comprises enumerations types, these enumerations are not split up by the
Technology Converter. To get the value of the enumeration, connect an Enumeration
Converter to the corresponding output of the Technology Converter.
For every Technology Converter and Enumeration Converter an online help window, displaying the interface description is available. Select the Technology Converter and press
F1 to get the interface description.
6.4.4 IEC61131 Program Cycle Time
IEC61131 programs are performed in a periodical manner. IEC61131 tasks are used do
control the execution of an IEC61131 program. As shown in Figure 44 several default tasks
are defined within the template project. Right click on the clock symbol and select properties to change the cycle time of the task.
As described in section 6.4 a program instance is required to execute the IEC61131
program. The cycle time of the IEC61131 program is controlled by the task assigned to the program instance. In order to change the cycle time right click on the program instance and select properties. In the upcoming window the task assignment for the selected program
type can be changed, see Figure 48.
Figure 48: Task assignment
Please take care when defining names for the tasks. The names displayed in the project view are symbolic names, they do not correspond to the settings for the cycle time, even if the
L-INX template project use the configured cycle time as task name.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 68 LOYTEC
6.4.5 CPU Overload
Several conditions affect the CPU utilization of the IEC61131 program. As a result it is not possible to predict the system load caused by the IEC61131 program. E.g. the following parameters are of particular importance when designing IEC61131 programs:
Number of inputs and outputs handled by the I/O driver.
Complexity of the logic in the running IEC61131 program.
Number of simultaneously running program instances on one L-INX.
Cycle time of IEC61131 programs.
logiCAD breakpoint support and force-able code enabled or disabled
The developer of the IEC61131 program is able to check the current system load within the
Web UI. To get a rough estimate of the CPU load investigate the PLC-LED. Every time, the system load increases 80% for a certain period of time, the PLC-LED switches to red until the system load goes below 80%.
In case of CPU overload, the IEC61131 program may not be able to finish its work within the defined cycle time. Adapt the program in order to reduce the total system load below
80%. Here are a few tips to keep the CPU load down:
Increase the cycle time, so that the task may finish in time before the next cycle start is scheduled. The PLC kernel will always schedule the next run at an absolute time, no matter how long the previous run took, in order to compensate for irregular execution times and keep a steady cycle time if possible.
Reduce the number of I/O variables, to reduce the load caused by exchanging data between the PLC program and the data points of the automation server.
Reduce the number of independent tasks and try to place as much functionality as possible into one task. Every running task will call the I/O driver for new inputs and outputs independently, therefore two tasks running at a 1s cycle time each will cause twice the I/O load of one task running at 1s cycle time.
Take special care about the complexity of function blocks which are used a lot.
Bad performance of one such block may dramatically increase CPU load if it needs to be calculated several hundred times in one cycle.
Try to disable breakpoint support and force-able code when generating code for the target, to get the most efficient PLC code out of your logic.
For complex designs, it may be possible to add a state machine using SFC elements and enable/disable large parts of the logic based on the current state of operation.
Whenever a function does not need to calculate new output values under certain conditions, use the built-in EN input of the block to disable execution and thus reduce the required CPU time, instead of adding your own ‘Enable’ input which causes the logic to ‘behave’ as if it would be disabled, while it is actually calculated every cycle. This is similar to power saving methods used in modern electronic devices. Parts which are not required are put into a low power mode instead of keeping them running in an unproductive state.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 69 LOYTEC
6.4.6 I/O Driver Settings
Before starting the IEC61131 program, the device performs a check on all defined global variables, which are marked %I, %O, or %M in the physical address parameter. For all variables, which cannot be loaded, because the corresponding data points cannot be located on the device, the I/O driver reports a warning in the system log and shows a listing on the
Web interface.
Since IEC61131 program and the data point configuration are downloaded separately, it may be possible that the IEC61131 program does not match the currently active data point interface. In this case it could be dangerous to write values onto those potentially wrong data points. The fact that there are any variables that could not be loaded is taken as an indication for a configuration mismatch. The I/O Check feature disables the I/O driver of the IEC61131 kernel automatically in this situation. This setting is enabled by default in a new configuration. In the rare case that it is intended to have missing data points, this feature can be disabled in the Configurator. In the system settings de-select the I/O check
(see Figure 49). If the I/O driver is disabled, it can be temporarily enabled again on the Web
interface until the next reboot.
Figure 49: System settings for logiCAD I/O settings.
The project setting Enforce cyclic output update enables a cyclic update of output data points, which will ensure that those output data points will contain the calculated value after each cycle. This is the default setting. It can be disabled, if the output data point shall be written only if the calculated value changes. In this mode the output data point can be modified over the Web UI for debugging reasons until the IEC61131 program calculates a new value. This mode can also be used to implement an event-style output operation.
6.4.7 PLC Conflicts
PLC output variables are cyclically updating the respective data points, which are configured as PLC out. If those data points are also written to by other objects (e.g. output of a math object, receiver in a connection) this will not have the desired effect. Also favorites that are PLC out and linked to a PLC out data point will result in two different
PLC output variables writing to one and the same data point.
The PLC Conflicts tab provides information for detecting such write conflicts on PLC out data points. The tab shows a list of PLC write conflicts and the writing objects, which are in conflict with a PLC out data point. Each reported conflict line can be selected. By clicking the Go to data point button the Configurator navigates to the conflicting object.
Figure 50: PLC conflicts tab.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 70 LOYTEC
An example is shown in Figure 50. The user register ‘HeatExchangeON_Write’ is written to
by the PLC, because it is PLC out. But the register is also an output in the math object
‘VE01_HeatExchange’. To resolve the conflict, either remove the register from the math object or remove the PLC out check box from the user register. For doing the latter, select the conflict line reporting the register and select Go to data point. Then uncheck PLC out on the data point.
6.5 Workflows for the L-INX
6.5.1 Starting with Data Points
This workflow is based on defining data points used for the IEC61131 program in the
L-INX Configurator and then export them to logiCAD. Figure 51 presents the basic steps of
this workflow. To follow the steps refer to the quick-start description of Section 3.6. Refer
to the LINX Configurator User Manual [2] about additional information how to gather information from the network.

It is assumed that there are already network data points (CEA-709, BACnet, L-IOB, etc.) available. Clicking the Export variables to logiCAD button in the Configurator creates the
IEC61131 variables in logiCAD. The following rules are applied in this process:
The name of the global variables object is derived from the technology base folder
(e.g. CEA709, User Registers, etc.). If there is no matching global variables object one is created. If there is already a suitable global variables object, the existing variables are saved.
There is already a suitable global variables object: If there is an old and new variable with identical name, the type of the variable is checked. In case of a type mismatch of the old and new variable, the old one is discarded and the new one is imported. Additional a warning is printed on the Error-state viewer.
The name of the global variables object represents the folder name in the L-INX
Configurator.
After exporting the data points as global variables to logiCAD, they can be used in the
Functionplan ‘Plan_1’. To open the respective global variables folder double-click on it. To use the imported variables simply drag and drop the required global variable on to the
Functionplan, see Figure 52. The external variables (see Section 6.5.2) are automatically
created when adding the global variable to the Functionplan.
Figure 52: Adding global variables to Functionplans
After adding function blocks that perform the expected work, the IEC61131 program is
ready to compile and download (see Section 6.4.2).
6.5.2 Starting with logiCAD
This section introduces a workflow how to develop a new IEC61131 program from scratch
using logiCAD. Figure 53 shows the necessary steps to perform. For starting a new
logiCAD project refer to the quick-start of Section 3.6.

The dark grey areas on the left and right side are intended to place the input and output variables, the light grey area is used to place the functional blocks.
As described above, global variables are used to interface IEC61131 data points on the
LINX-110 device. As assumed for the current workflow, the IEC61131 data points are created on information based on the global variables exported from logiCAD. Hence, for designing the program, external variables are used during the design phase. To create a new

L-INX/L-GATE User Manual 73 LOYTEC variable select the VAR_EXTERNAL tab, right click in the declaration area and select
Figure 55: New external variable
In the upcoming dialog the name and the type declaration of the variable must be specified.
The type declaration can be done directly by prompting the type into the declaration field, by selecting the type from the pull-down menu or by drag-and-drop of a specific type from
the project tree, see Figure 56. Finally, the new variable is added by pressing the Add
button.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 74 LOYTEC
Figure 56: External variable type declaration
The created variable is added to the declaration area and placed to the drawing area by drag-and-drop. At this time the direction of the external variable is not defined, it can be used as input as well as output variable.
Figure 57: Drag-and-drop external variable to drawing area
Please take care to use an external variable only as input OR output. After adding the external variables to the drawing area, add function blocks to perform the desired actions,
see Figure 58 for a sample configuration.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 75 LOYTEC
Figure 58: Use external variables
The Functionplan ‘Plan_1’ represents now a simple program. It adds a defined value to the value of the input variable and sends the result to the output variable.
Add all expected functionality to the ‘Plan_1’ or use different Functionplans to split up the expected functionality into smaller pieces. But take care about the name and type declaration of external variables when using more than one Functionplan. All external variables with the same name refer to the same global variable.
After adding all functionality, global variables matching the requirements of the defined external variables, must be generated. A tool automatically performs the process of generating the global variables object and the required global variables.
Figure 59: Auto-create global variables
To start the creation of global variables, based on external variables, Save all changes, then right click the L-INX device and select Global Variables Generate. Then the selected
L-INX resource is parsed and every program instance found is checked for external
appropriate program instances for these plans must be added to the resource before creating the global variables. Anyway, only Functionplans referred from program instances are executed.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 76 LOYTEC
Figure 60: Created global variables object
Now there is a global variables object called IEC61131 Variables available, containing all global representations of the external variables defined before. The Error-state viewer
reports all processed program instances and added variables, see Figure 60 for details.
The global variables are crated based on the following rules:
The direction of the variable is determined based on the graphical representation,
Figure 61: Direction of global variables
Every external variable connected on the right terminal results in a global input variable. External variables connected on the left terminal or on both sides results in a global output variable. Variables connected on both sides can either be used
for the force update feature (see section 6.6.1) or as marker (see section 6.6.4). As
the tool can not distinguish between these two possibilities, per default a global output variable is created.
If there is already a global variables object, only new variables are added. In case of external variables using the same name as an already existing global variable, the new definition is used and a warning is printed in the Error-state viewer.
In case of two Functionplans, each referring to a global variable with the same name but a different type, the creation process is stopped and an error is printed in the Error-state viewer.
Now the IEC61131 program is ready to compile and download, refer to section 6.4.2 for
details.
Based on the above created global variables corresponding IEC61131 data points are created on the L-INX. For doing so, start the L-INX Configurator and click the speed button
Import variables from logiCAD. Data points are created in the IEC61131 Variables folder.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 77 LOYTEC
The Configurator reports the results of the import. For the import process the following rules are applied:
New variables are added
Variables with same name and type are ignored
If there are variables with the same name but different type or direction, the variable to import is ignored and a warning is added to the import log.
The name of the folder to import the new variables corresponds to the name of the global
variables object. Figure 62 shows the result of the import process.
Figure 62: Connect IEC61131 variables
To create the appropriate network data points for all imported IEC61131 variables select the IEC61131 Variables folder and press the button Generate and Connect Network <->
IEC61131 variable from folder. Check the log output for errors and finally download the configuration to the L-INX device.
After rebooting the L-INX device the IEC61131 program is up and running. Check the PLC
LED for potential overload.
6.5.3 Pre-compiled IEC61131 Program
In opposite to the last two chapters it is assumed that there are already some components finished, hence starting up from scratch is not suitable. Second, there is the possibility to have an already defined IEC61131 program or an already fixed network interface.
Starting with an already precompiled IEC61131 program results in a similar workflow as
presented in Section 6.5.1. The difference is that all logiCAD related tasks are missing. As
the IEC61131 program is compiled, the name of the IEC61131 data points is already fixed.
The definitions for the data points must be available either in form of a CSV file to import to the L-INX Configurator or as part of a L-INX Configurator project. If the network interface for the L-INX was not already defined, the L-INX Configurator can be used to generate and connect the needed data points.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 78 LOYTEC
Additionally, there is the possibility that also the network data points are already fixed or that a given, user-defined interface is necessary. Then the developer has to connect the
IEC61131 data points to the corresponding network data points by himself.
Finally, after downloading the configuration and rebooting the L-INX, the IEC61131 program can be downloaded to the L-INX via the Web UI or the L-INX Configurator. After a final reboot the L-INX loads and executes the IEC61131 program.
6.6 Additional Features
6.6.1 Force Update Functionality
Per default the IEC61131 program only sends updates on changed output values. Every program cycle the input values are fetched, the IEC61131 program is executed and the calculated values are sent to the output driver. If the old values are identically with the new one no updates are sent to the IEC61131 data points. As a result no update is sent to the network.
For some applications, e.g. for a scene controller, it is necessary to send an update on request. E.g. every time the input value is updated, the output value is forwarded to the network, regardless if the value of the output value was changed or not.
For implementing this feature, special vendor blocks are available. First it is necessary to check if there was an update on a selected input within the last execution cycle of the running IEC61131 program. That functionality is offered by the function block Update
Notify located in the StandardLibsLoytec_Support folder. Second, an output must be forced to send an update even if the value was not changed. The function block Force
Update is used for that functionality, it is located in the StandardLibsLoytec_Support.
Important:
Figure 63: Force update
Figure 63 depicts how to use the force update functionality. Besides of the part of the
IEC61131 program that defines the calculations to perform (lower half of Figure 63),
additional logic for the force update functionality is required. The global input variable that is monitored for changes is connected to the Update Notification function block. As a result, the Boolean output ‘Updated’ is set to TRUE for one program cycle, if the value of the connected variable has been updated since the last cycle start. To force the I/O driver send out an update, the global output variable, which shall be updated, is connected to ‘Output’ of the Force Update block. Hence, every time the ‘Update’ input of the Force Update block is TRUE, the connected global output variable sends out an update at the end of the program cycle.
Every global variable connected to the update notification or force update block must be connected via the right-hand side terminal!
6.6.2 Using UNVT variables
Similar to the predefined CEA709 data types and the technology converter functions, userdefined network variable data types can be used. The L-INX Configurator supports the developer to generate the type definitions needed for UNVTs and enumerations based on resources files. L ON M ARK
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 79 LOYTEC
To generate type definitionf for UNVTs in logiCAD
1. Start the L-INX Configurator.
2. Select the menu Tools Export NV Resource File….
3. Select the resource file to be exported. Select structured text as format and export the file to a location of your choice by clicking Export Selected.
4. To import the created type definition file into logiCAD, add a new library to the project. Right-click on the created library and select Export/Import Start ST-
Import.
5. Select the file to be imported and check the Error-state viewer for the results of the import process.
Using the newly created data types, suitable technology converter function blocks can be created. For each UNVT type, create a normal function block to convert an input of the
UNVT type to a number of standard IEC61131 data types and vice versa. You may look at the technology converter blocks for SNVT types which are provided by LOYTEC, to get ideas how to implement your own converter functions.
6.6.3 Create Your Own Data Type
For special applications, custom IEC61131 compliant data types may be created by the user, which do not correspond to any CEA709 network type but should still be available as a data point on the L-INX automation server, in order to access the data point value from the Web interface or over XML as a parameter. Further, such data points can also be made persistent, which makes variables of such custom data types persistent.
Most of the IEC61131 data types may be used as global variables on the device and the
L-INX Configurator will be able to create a suitable register data point for the IEC61131 data type. Supported data types include custom enumeration types (a multi-state register with the required states will be created automatically), strings (a string data point with a maximum length of 128 characters will be built), structures and simple arrays.
If such structured variables shall be mapped to a data point, which shall only be persistent to store the structure but no access to its elements are required in the data point interface create a suitable register data point during the IEC61131 variable import. In this case the data size of custom structures cannot be determined automatically, so the L-INX
Configurator does not know how to create a suitable user data point. As a workaround, the type name must contain the desired size of the data point in bytes, for example:
MyStructuredType(UT16) will tell the L-INX Configurator to create an IEC61131 register of type ‘user’ with a length of 16 bytes, to hold the data for the IEC61131 structure defined in the logiCAD program.
As an alternative, structures and arrays the logiCAD type definitions can be exported to the
Configurator using structured text. The Configurator builds custom structured data point types in the logiCAD category out of the structured text definitions. In this case, the exact data size of a user register is determined by the structured data type. Structure members of the logiCAD types are represented as a tree of sub-data points. logiCAD arrays (like
ARRAY [1..16] OF INT) are represented as a series of single data points where each data
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 80 LOYTEC point represents one array element. Note, that the array in logiCAD can still be access by index.
To Use logiCAD Types in User Registers
1. In logiCAD right-click on the library with the types that shall be exported and select
Export code….
2. In the export dialog choose ‘.ST’ as the export configuration, select the option single
file and choose a target file (see Figure 64). Then click Export, which creates the
structured text file.
Figure 64: Export logiCAD types as structured text.
3. In the Configurator go to the menu Tools Manage Structured Types.
4. In the dialog choose the type Category ‘logiCAD’.
5. Click the speed button Load types from disk .
6. In the dialog Import Types from Disk click on .
7. In the file selector dialog, choose the file type Structured Text ‘.ST’ and open the previously exported file.
8. The available types in the structured text file appear on the left-hand side of the dialog.
Transfer all listed types to the Configurator by clicking . Alternatively select specific types and click . Then click Close.
9. In the Manage Structured Types dialog, the imported logiCAD types are now listed.
Click Close.
10. Now you are able to create a structured user register. For Custom Type choose one of the imported logiCAD structure types.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 81 LOYTEC
6.6.4 Using Persistent Data Points and Markers
Persistent data points are data points on the device that hold their value even after power loss. In the IEC61131 program there is no difference in handling global variables connected to persistent data points or to non-persistent data points. When using global variables on the device resource that shall retain their values after a reboot, the respective data points need to be configured with the persistent flag in the L-INX Configurator.
Global input variables marked as persistent, supply the IEC61131 program every time with the last received, valid data, even after a power failure. To enable this behavior, set the respective input data points persistent in the L-INX Configurator and download the data point configuration to the device.
Global variables declared as marker can be used as input and output variable in IEC61131 programs. LogiCAD is not able to distinguish markers from global output variables used in
combination with the force update feature, see Figure 63. As a result it is not possible to
create a global variables object holding markers automatically. The procedure as described
in Section 6.5.1 is not able to decide when to create an output variable or a marker. Markers
must be created manually by adding them to the global variables object and setting the physical address to %M.
6.6.5 Using Retain Variables
Retain variables can be used to maintain certain states or parameters of a program over a reboot in those variables, which cannot be kept in persistent data points. Typically, input variables (%I) will be marked as retain variables. For doing so check the RETAIN attribute
in the variable declaration when creating or editing a variable as shown in Figure 65.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 82 LOYTEC
Figure 65: Declaring a retain variable.
The retain attribute should be used in global variables and local variables on function plan only. Global variables on the device resource are managed by the I/O driver and must not
use the retain attribute. Instead data point persistency (see Section 6.6.4) must be used for
those variables. Furthermore, it is not recommended to mark local variables in function blocks as retain variables.
The contents of retain variables are written to Flash storage every 5 minutes and when shutting down the device. This provides good compromise between write granularity for normal operation and ensuring Flash life-time. If the contents shall be written explicitly at a defined time, use the RetainCtl function block located in the logi.library/Data folder.
Connect the store input (S) and set this input TRUE for one cycle to trigger writing retain data. Make sure to set the input back to FALSE after this cycle to avoid multiple consecutive writes.
6.6.6 L-INX System Registers, System Time
L-INX system registers, such as the system time or the CPU load, can be used within
IEC61131 programs. Therefore, for each system input variable, a global input variable of type UDINT may be created within the IEC61131 program. Then, connections to the appropriate system registers are created manually with the L-INX Configurator.
To use the system time within the IEC61131 program, connect the AtoDT converter
(located in the StandardLibs->IEC61131-3_ (EXT) folder) to the global input variable that receives the system time.
6.6.7 Code Protection
There are 4 data points used for code protection. These data points, in combination with an adapted IEC61131 program, can be used to protect your 61131-Program Intellectual
Property. Please contact LOYTEC sales for further information.
6.6.8 Using Structured Data Point Members
Some network technologies provide structured data points. Their types are defined by the network technology and are available in the Configurator. Those structure types can either
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 83 LOYTEC
be used in logiCAD by implementing a technology converter (see Section 6.4.3) or by
exposing the sub-data points of the respective structures.
To Use Sub-Data Points in logiCAD
1. In the Configurator, expand the structured data point and expose the desired sub-data points of its structure members to the PLC.
2. Export the variables to logiCAD. The exposed structure members appear for example as ‘/UR/mod1_Read.byte_0’ in the ‘User Registers’ global variables block.
3. Export the types for the respective type category in the menu Tools Manage
Structured Types… . This opens the structured types management dialog.
4. Choose the type Category, e.g. ‘Modbus’.
5. Click the speed button Save to disk .
6. In the dialog Export Type to Disk choose a Disk Repository Path and select the extension ‘.ST’ for structured text.
7. Copy all listed types to the disk repository by clicking . Alternatively select specific types and click . Then click Save and exit the dialog.
8. In logiCAD create a new library folder, e.g. ‘modbus_types’.
9. Right-click on that new library and select Export/Import Start ST Import. In the file dialog choose the previously exported structured text file.
10. The type definitions are now available in the new library.
6.6.9 BACnet Server Objects
BACnet server objects provide additional functionality compared to other network technologies. The most important tasks in an IEC61131 program are:
Reading sensor data from BACnet input objects,
writing to commandable BACnet objects with a priority,
revoking values from commandable BACnet objects,
handling objects when out of service.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 84 LOYTEC
The default data flow direction for a commandable BACnet object (e.g. AO) is input to the
PLC (%I). This means its value is commanded over the BACnet network and the logic processes the resulting value. The default for non-commandable BACnet objects (e.g. AI) is output (%O). This means the logic writes the value, which is read out of the object over the
BACnet network. With this type of variables the BACnet objects are treated as variables of the IEC61131 program.
When exposing local I/O to BACnet server objects, the BACnet objects represent the I/O values and the IEC61131 program behaves like a user from the network on those objects.
Typically sensor values are connected to BACnet input objects (e.g. AI). To read the sensor value the PLC needs an input variable. Since the default data point direction is output, a separate access data point for the PLC must be created. For doing so, use the Add/Remove
BACnet properties option from the context menu of the data point list and create a read
data point for the Present_Value. Figure 66 shows an example, where the PLC uses the
input ‘/BAC/AI2.Present_Value_Read’ to get the sensor values from AI2.
Figure 66: PLC with BACnet objects.
BACnet output objects (e.g. AO) are connected to actuator I/Os. On those BACnet objects the PLC behaves like a user from the network and needs to write and revoke values at certain priority slots. For writing with a certain priority to a commandable object, a priority write data point needs to be created (see LINX Configurator User Manual [2], Section
BACnet Configuration, Write and Read with Priority). This data point is configured with a
BACnet write priority in the Configurator and used as an output in the PLC. The example in
Figure 66 writes with priority ‘4’ to AO1 over ‘/BAC/AO1_pri4’.
To revoke values in commandable server objects, the SetValueState function block must be used. It is located in the Loytec_Support/Service folder. The I/O variable of the controlled
BACnet object is connected to the Variable input of the function block. A Boolean signal needs to be connected to the Invalid input. When this input changes to TRUE, the value is revoked at the respective priority slot. When it remains TRUE in the next cycle the service
function block is idle. Figure 66 shows an example, how to revoke a value in ‘AO1’ at
priority slot ‘4’.
With the out-of-service feature BACnet server objects can be decoupled from the senor and actuator I/O equipment. When taken out of service, the I/O variables of the PLC are then decoupled from the network. The input variable Present_Value_Read of an AI no longer tracks the sensor value but reflects the value set in the AI from a BACnet OWS. This holds true for all non-commandable BACnet objects. Writing to the priority output variable of an
AO only updates the priority array but no longer drives the actuator. This holds true for all commandable BACnet objects.
The out-of-service state is reflected in the data point status and can be accessed with the
ValueState function block. This function block reads the value state and is used in a similar fashion as the SetValueState function block.
6.6.10 Custom Serial Protocols
A logiCAD program can implement simple custom serial protocols using the SerialComm function block. The logic program assigns the Baud rate settings for the protocol as well as a logical bus number. This bus number can be selected on the port configuration Web UI in order to activate the custom serial protocol on that port.
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 85 LOYTEC
Custom serial protocols with the following communication properties can be supported:
ASCII protocol: The serial communication block works with strings that are transmitted and received.
Line-Oriented: Each command and reply is modeled as a text line. The line can be terminated by any combination of CR and LF.
Start/End Character: If not line-oriented, a start and end character can be specified to detect start and end of a frame. The end character must be escaped in the frame content.
Master/Slave: The serial communication block is a master, which sends requests over the serial port and expects slave(s) to respond. The serial communication block can also implement a slave, which receives requests and creates responses.
Addressing Information: If the serial protocol has more than one slave, each request must have address information, which selects a specific slave. Especially for RS-485 bus communication address information is required. Since frames sent out are also received, they need to be filtered out by address.
To start the implementation of a custom serial protocol use the function block SerialComm located in the StandardLibsLoytec_SupportService folder. Add a bus number and
communication settings as a string (e.g., „38400-8N1-X“) as shown in Figure 67. Best
practice for an implementation is to use an SFC-based state machine. All necessary input and output signals are available on this function block. The minimum number of states is
Idle, Rx, Tx. For a full specification of this block use the F1 help.
Figure 67: Example for the SerialComm block.
String processing may build commands from data point values and extract data from responses, which are written to data points. The data points should be user registers that are organized into a separate sub-folder for the custom serial protocol.

7 Firmware Update
LOYTEC
The L-INX and L-GATE firmware support remote upgrade over the network and the serial console.
To guarantee that the device is not destroyed due to a failed firmware update, the firmware consists of two images:
1. The fallback image,
2. the primary image.
The fallback image cannot be changed. Thus, if the update of the primary image fails or the image is destroyed by some other means, the fallback image is booted and allows reinstalling a valid primary image. When the device boots up with the fallback image, the all port LEDs are flashing red.
The following firmware images are available for the different device models:
LINX-10X/11X/20X/21X: linx_10x_11x_20x_21x_x_y_z.dl,
LINX-12X/15X/22X/LGATE-95X: linx_12x_15x_22x_lgate95x_x_y_z.dl,
LGATE-900: lgate900_x_y_z.dl.
7.1 Firmware Update via the Configurator
The primary image can be updated using the Configurator. For this purpose, it is recommended to have the device connected to the Ethernet and to have a valid IP
configuration (see Section 3.2). The Configurator must be installed as described in the
LINX Configurator User Manual [2].

8.3 Packet Capture
8.3.1 Configure Remote Packet Capture
Remote packet capture is able to capture packets on the Ethernet port and on the MS/TP port. The MS/TP remote packet capture option is only available, if the MS/TP port is enabled in the port configuration on the device. To enable the remote packet capture feature, go to the Ethernet port configuration and enable Remote packet capture as shown
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 93 LOYTEC
Figure 76: Remote packet capture port configuration.
The default Port setting may be changed to the desired port. Normally, this can be left at its default. If No authentication is selected, the device will allow incoming capture connections without requiring any credentials. If Username and Password is selected as authentication method, the client Wireshark will be required to provide valid credentials before the capture session can be started. Note, that only the users admin and operator are allowed to connect if this authentication method is selected.
Click the Save Settings button to save the configuration. The changes take effect and do not require to reboot the device. The remote capture can also be disabled again without a reboot.
8.3.2 Enable Local Capture
The device provides a local capture feature. With local capture enabled the device logs packets to an internal ring buffer. The log can be downloaded from the Web interface. To verify that the device is set up correctly, go to Statistics Packet capture as shown in
Figure 77: Packet capture statistics.
Verify that the Ethernet and optionally the MS/TP capture ports are listed in the Available
capture ports table and that the Remote capture status for these ports reads
Disconnected. If the MS/TP port is not listed on a device that has an MS/TP port, make sure that the MS/TP port is enabled in the port configuration.
To log offline without a Wireshark attached to the device, click the check box Local
Capture. The device will then start capturing packets and stores them in a ring buffer. The log file can be downloaded by clicking on the button Download capture files. This stores a
LOYTEC electronics GmbH
L-INX/L-GATE User Manual 94 LOYTEC
ZIP archive of the packet capture to your local hard drive. Capture files can be cleared by clicking Clear Files. After a reboot all local capture files are lost.
For local Ethernet capture additional capture filters can be added to narrow down the amount of logged packets to those of interest. Select the line Ethernet port line and enter a basic filter expression at the bottom of the page. Then click on Add and add more filters.
Finally click on Save Filters to store and activate the local capture filters. Figure 78 shows
an example filter for packets with source IP address 192.168.24.100.
