CLIWP CONTROL BY LOYTEC LIOB-585
LIOB-585 I/O controllers are compact, IP-enabled, programmable
automation stations for LonMark systems and BACnet/IP networks
with physical inputs and outputs and integrated graphical display.
COMMUNICATION
The LIOB-585 I/O Controller is equipped with two Ethernet ports
including a built-in Ethernet. This makes it possible to build a
daisy-chain line topology of up to 20 devices, which reduces
network installation costs. Devices with dual Ethernet ports also
allow configuring a redundant Ethernet installation (ring topology)
which increases reliability. The redundant Ethernet topology is
enabled by the Rapid Spanning Tree Protocol (RSTP), which is
supported by most managed switches.
Technology data points are automatically exposed as OPC tags
for higher-level OPC client applications, higher-level OPC client
applications or the L-WEB system through the integrated OPC
server that provides SSL encrypted Web Services (OPC XML-
DA) or UA secure conversation (OPC UA).
The L-IOB I/ O controllers also enable data exchange via global
connections (network-wide data exchange), offer AST™ functions
(Alarming, Scheduling, and Trending), store customized graphic
pages for display on LWEB-802/ 803, and can be seamlessly
integrated into the LWEB-900 building management system.
LIOB-585 I/O controllers implement the BACnet Building
Controller (B-BC) profile and are BTL certified.
IOT INTEGRATION
The IoT function (Node.js) makes it possible to connect the
system to almost any cloud service either to upload historical data
to analysis services, deliver alarm messages to alarm processing
services or to operate parts of the control system via a cloud
service (e.g. scheduling based on web calendars or reservation
systems).
It is also possible to process information from the Internet, such as
weather data, into forecast-based control. Finally, the JavaScript
core also makes it possible to implement serial protocols to non-
standard equipment in primary plant control.
HARDWARE INSTALLATION
An LIOB-58x I/O controller is connected to a BACnet network
using the Ethernet/IP port of the L-IOB device. The device must be
powered, for example, with an LPOW-2415A power supply.
BACNET START-UP OR CONFIGURATION
For LIOB-58x models, the initial IP and BACnet configuration must
be performed on the LCD user interface or the web user interface.
On the LCD interface of the LIOB-48x/58x, the IP address and
Ethernet status is displayed instead of the PLC status.
The menu items are shown below.
Figure 1. LCD user interface main screen
Turn the jog dial to navigate between menu items and press to
enter a menu or go to selection mode. When in selection mode,
turn the jog dial to change the value and press again to exit
selection. The data points icon (
) allows you to navigate
through the data points of the device.
LIOB-48x/58x devices can additionally host a LIOB-45x/55x
device in LIOB-IP mode. In this case, there will be an additional
LIOB-IP menu on the main screen.
The device configuration icon () allows configuring the basic
device settings. Navigate, for example, to the Device Management
submenu “”, shown in Figure 2.
