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