Page 28: Getting Started With The L-Inx Configurator
Before setting up a working IEC61131 program or creating an L-Web visualization, the data points of the L-INX automation server need to be set up. These can be data points of L-IOB I/Os, network variables, BACnet objects, and other available technologies. Before executing the steps below, install the L-INX Configurator Software from the ‗setup.exe‘.

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.
Page 85: Timing Parameters
L-INX User Manual LOYTEC 5.1.2 Timing Parameters Apart from the meta-data, data points can be configured with a number of timing parameters. The following properties are available to input or output data points, respectively:  Pollcycle (input): The value is given in seconds, which specifies that this data point periodically polls data from the source.

Page 185: Configuration Server For Managing The Ip-852 Channel
The L-INX contains an embedded configuration server and can therefore replace the PC. The configuration server can be enabled in the L-INX in the CEA-852 server configuration menu in Section 4.2.9. This configuration server can manage one IP-852 channel and up to 256 devices on this IP-852 channel.

See Section 7.2.5 on compatibility with the i.LON 600. 7.3.1 Automatic NAT Configuration In order to use the L-INX behind a firewall, the public NAT address and the local IP address must be set in the IP configuration menu (see Section 4.2.4). By default, the NAT address is determined automatically when adding the L-INX to the channel in the configuration server.

Figure 153, the L-INX with private address 192.168.1.100 also acts as a configuration server. If the CS is activated on a L-INX behind a NAT router, the NAT router must have a fixed public IP address. The L-INX with the CS also cannot use automatic NAT discovery. In this case, enter the NAT address of the NAT router manually in the IP configuration menu (Auto-NAT can no longer be enabled on a L-INX with a CS).

L-INX User Manual LOYTEC  alarming is supported via nvoAlarm (SNVT_alarm) and nvoAlarm_2 (SNVT_alarm_2). This allows devices supporting the L alarm notifier profile to receive alarms generated by the device and react with a defined action (e.g., send an email). By supporting both alarm SNVTs, SNVT_alarm and SNVT_alarm_2, legacy and state-of-the-art alarm handling is supported.
Page 282 L-INX User Manual LOYTEC  nvoElapsedTime (SNVT_elapsed_tm): Time since device powered up or since the statistics for this port where reset. The statistics can be reset with the network variable nviClearStat in the node object (see Section 13.2.2) or if the node is reset with a network management command (e.g., while the device is commissioned).

Page 285 Device Information A whole set of properties provides general purpose information about the device. Vendor_Name (Read-Only). The value of this property is ―LOYTEC electronics GmbH‖. Vendor_Identifier (Read-Only). A numerical value identifying the BACnet vendor. The value of this property is 178.
Page 286 L-INX User Manual LOYTEC 13.3.1.3 Object Database The following properties provide information about the BACnet objects contained in the device. Object_List (Read-Only). This property holds a BACnetARRAY of object IDs (object type, object instance pairs), one object ID for each object within the device that is accessible through BACnet services.
Page 287 L-INX User Manual LOYTEC BACnet addresses. This property tells a user which BACnet address the device will actually use when trying to communicate with another device known only by its device instance number. This information can be helpful when diagnosing network configuration problems.
Page 288 L-INX User Manual LOYTEC Time_Synchronization_Recipients (Read-Writable). This list of recipients will receive TimeSynchronization requests on time synchronization events. A recipients is either specified by its device ID (the object ID of its Device object), or its BACnet address. By default, this list is empty.
Page 289 L-INX User Manual LOYTEC 13.3.1.8 Backup & Restore The following properties are related to backup & restore procedures. Configuration_Files (Read-Only). The contents of this property is an array of object IDs of File objects that can backed-up or restored during a BACnet backup or restore procedure.

When using the Free Topology Segment feature of the FT, only one termination (Figure 229) is required and can be placed anywhere on the free topology segment. Instead of building the termination, one can order the L-Term module (LT-33) from LOYTEC, which can be used to properly terminate the bus.
Page 292: M-Bus
L-INX User Manual LOYTEC 14.2 M-Bus The device uses the RS-232 console interface for the connection to an external M-Bus transceiver (repeater). The M-Bus specifies no special topology requirement, though it is not advised to use a ring topology. A maximum of 250 M-Bus slave devices can be connected to the bus, in fact, the external bus transceiver can have a lower limit of connected devices.
Page 293: Firmware Update
LOYTEC 15 Firmware Update The L-INX firmware supports remote upgrade over the network and the serial console. To guarantee that the L-INX is not destroyed due to a failed firmware update, the firmware consists of two images: The fallback image, the primary image.
Page 294 L-INX User Manual LOYTEC Figure 232: FTP connection dialog. In the FTP connection dialog, enter the IP address of the device as well as the admin user‘s password. The default password is ‗loytec4u‘ (older firmware versions used ‗admin‘). This can be changed via the Web interface (see Section 4.1) and reset via the console UI (see Section 16.2.2).
Page 295: Firmware Update Via The Console
11. The device‘s firmware has now been successfully upgraded. 15.2 Firmware Update via the Console On L-INX models with the console connector it is possible to upgrade the device over this interface. To download the firmware via the console interface, the device must be connected to the RS-232 port (EIA-232) of a PC via its console interface as described in Section 16.2.1.
Page 296 L-INX User Manual LOYTEC Figure 236: Progress Bar during Firmware Download. If the upgrade is successful, the following window appears (Figure 237). Figure 237: Successful Firmware Upgrade. Double check that the new firmware is executed by selecting ‗1‘ and pressing Enter in the console window.
