L‑VIS Touch Panels for LonMark, BACnet, and Modbus networks are ideally suited

L‑WEB, L‑STUDIO
for visualization and operation of various applications in building automation.
L‑VIS Touch Panels visualize building systems, can be used as room operator pan‑
els, in hospital operation or isolation rooms, conference and reception areas. The
fully customizable user screens can show dynamic pages that are easy to navigate.
L‑VIS Touch Panels make use of an extremely low power embedded controller
platform and operating system. This makes L‑VIS resistant against problems when
re-booting after power outage and also against any viruses.

L‑ROC
L‑VIS impresses with its timeless design, harmonic integration into modern and
historical architecture, and with its extremely user friendly concept. The shallow
installation depth and low thermal power loss allow mounting in almost any
location.

Dynamic Graphical Pages

VPN VNC RNI

L‑DALI
The graphical pages may consist of multiple dynamic graphical controls that show
y=f(x) the current plant status in real time. It is also possible to access decentralized
schedules, alarm servers, or trends. The graphical projects are designed with the
L‑VIS/‌L‑WEB configuration tool free of charge. Without any know-how in HTML or
Java, user specific graphical pages can be created. Dynamic information is shown
through value or text controls, changing symbols, bar charts, trend views, alarm
Routers, NIC

and event lists, or schedule controls. The L‑VIS/‌L‑WEB configuration tool allows for
using most of the pixel graphic formats (GIF, JPG, BMP, TIFF, PNG, MNG, ICO), vector
graphics (SVG) and alpha blending.

Playback of Audio Files and Streams

The L‑VIS Touch Panel supports the playback of stereo MP3, WAV, and MP3 streams
Interfaces

(for example webradio). The playback will be started or stopped by the respective
action object. The action object is linked to one of the available audio files or to
the URL of an MP3 stream. When accessing a playback via LWEB‑802 or LWEB‑803,
it will be executed locally on the client.

Automatic Page Generation

Accessories

Pages including data point names and values, alarm views, schedules, or trends
can be created automatically by the L‑VIS/L‑WEB configuration tool. This signifi‑
cantly reduces engineering time and cost.

Connectivity and Data Points
L‑WEB, L‑STUDIO

The L‑VIS Touch Panels support connectivity to LonMark Systems and BACnet net‑
works. In addition, the Touch Panels provide communication to Modbus either
as Master or Slave. For this purpose, Modbus TCP is supported exclusively and
Modbus RTU is available via the RS‑485 terminal.
22 L‑VIS Touch Panels communicate with LonMark Systems via IP‑852 (Ethernet/‌IP)
or TP/‌FT‑10 channels. The integrated remote network interface (Ethernet/‌IP) pro‑

BACnet networks are connected via BACnet/‌IP or BACnet MS/‌TP. The L‑VIS Touch
Panels implement the BACnet Building Controller (B-BC) profile and are BTL certi‑
fied. They include a fully featured built-in BACnet/‌IP to MS/‌TP router with BBMD
(BACnet Broadcast Management Device) and slave proxy functionality.
L‑INX

Math objects can calculate any kind of formula using data points available on the
device.
L‑VIS devices are equipped with two Ethernet ports. They can either be configured
to use the internal switch to interconnect the two ports or every port is configured
to work in a separate IP network.
L‑IOB

When the Ethernet ports are configured for two separate IP networks, one port
can be connected for instance to a WAN (Wide Area Network) with enabled net‑
work security (HTTPS) while the second port can be configured to be connected
to an insecure network (LAN) where the standard building automation protocols
like BACnet/‌IP, LON/‌IP, or Modbus TCP are used. These devices also feature firewall

functionality to isolate particular protocols or services between the ports.

1 A Room 111 Mo 24.08.2015 10:44
Using the internal switch, a daisy chained line topology of up to 20 devices can be
built, which reduces costs for network installation. The IP switch also allows the
80% setup of a redundant Ethernet installation (ring topology), which increases reli‑
ability. The redundant Ethernet topology is enabled by the Rapid Spanning Tree
