  • Page 9: Introduction

    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.
  • Page 10 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.

    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.

  • Page 12: Bacnet

    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.

  • Page 13: M-Bus

    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.

  • Page 14: Enocean

    LOYTEC 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].

  • Page 15: L-Iob

    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].

    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.

In the export dialog choose ‘.ST’ as the export configuration, select the option single file and choose a target file (see Figure 77).

    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.

    8.6.6 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 Sub-Data Points in logiCAD In the Configurator, expand the structured data point and expose the desired sub-data points of its structure members to the PLC.

    L-INX/L-GATE User Manual LOYTEC 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.
