The L-ROC Room Controller provides the basis for a revolutionary room automation system based on IP, which seamlessly integrates with native BACnet/IP networks and LonMark Systems at the controller level. Together with the L-STUDIO software flexible room solutions can be created with little effort and changed on demand. An integral part of the L-ROC System is a Web based room operation via an LWEB‑803/802 dashboard and the automatic generation of graphics for the L-VIS Touch Panel for local operation. For CEA‑709 room control units, CEA‑709 multi-sensors and other CEA‑709 devices can be connected via the LonMark TP/FT-10 channel on the L-ROC controller. Local inputs and outputs are provided via L-IOB I/O Modules. KNX S-mode devices can be connected through KNX TP1 by using the optional LKNX-300 module.

Flexible Room Concept for Room Automation

A room segment is the base unit of configuration in the L-ROC System. The L-ROC Library provides a set of functions for every window axis including:

  • Lighting control with constant light controller
  • Sun blind control with angle adjustment and year shade progression
  • Temperature control for heating, cooling, and ventilation
  • Occupancy detection
  • Window monitoring

Each L-ROC Room Controller can handle up to 16 room segments. Based on the various room segment types, larger buildings can be modeled in a hierarchical manner. Areas are built with an area manager by combining multiple room controllers. A floor manager manages multiple areas in one floor. Depending on the architecture, the building can be split up into areas and floors as needed.

Area/Floor Managers are responsible for handling functions needed for corridor, staircase, and bathroom lighting, or even ventilation. Floor managers facilitate the data communication between the floors and handle floor relevant functions.

Rooms can now be created arbitrarily in any size by moving, building, or removing partition walls. The resulting logical connections between the L-ROC Room Controllers will be built automatically. All graphical user interfaces and network connections are automatically generated and adapted respectively.l-roc_nomenklatur

AST™ for Every Room Segment

L-ROC provides a set of functions for Alarming, Scheduling, and Trending (AST™) for every room segment. Each room segment can be operated entirely independently. The AST™ functions are fully available to higher-level systems through BACnet/IP and Web services (L-WEB System). Distributed schedulers can be efficiently managed and changed with LWEB-900.

Room Communication through redundant or separated IP Network

L‑ROC Room Controllers are interconnected via a 100Base-T Ethernet network. Each L-ROC device is equipped with two Ethernet ports. It 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.

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 network security (HTTPS) while the second port can be configure to be connected to an insecure network (LAN) where the standard building automation protocols like BACnet/‌IP, LON/‌IP, or Modbus TCP are present. These devices also feature firewall functionality of course to isolate particular protocols or services between the ports.

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 allow the setup of 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.

Integrated L-WEB Room Operation

L-ROC controllers provide graphical user interfaces for room operation directly via an IP connection to the user, without the need for an additional web server. Graphic projects are distributed among the L-ROC Room Controllers and can be accessed by LWEB‑802/‌803 from any PC workstation, smart phone, or tablet PC running Android or iOS.

L-STATIntegration of the L-STAT Network Thermostat

Per L-ROC Room Controller up to 16 L-STAT room control devices can be integrated into building automation via Modbus RTU (RS-485) interface. In addition to the attractive, modern design and intuitive operation, L-STAT provides a range of other features to individually increase the room comfort.

Internal sensors measure temperature, humidity, condensation, occupancy, and also the CO2 value of the air. There is also the possibility to control room functions from remote via an IR remote control. Standard pushbuttons and external temperature sensors can be integrated through additional inputs. A built-in NFC chip (Near Field Communication) provides the ability to direct mobile devices to the address of the respective room website.

Connection to Higher-Level Systems

Higher-level systems can seamlessly integrate L-ROC Room Controllers via BACnet/IP, LonMark IP-852, or Web services (OPC).

All these protocols are simultaneously available. It is possible to integrate the L-ROC Room Controller in a BACnet Operator Workstation and at the same time L‑ROC will communicate with other CEA‑709 devices on the IP-852 channel. Moreover, a higher-level SCADA or ERP System (Facility Management) gets information directly from the L-ROC Room Controller by using Web services based on OPC.

Full LWEB-900 Support

The L-WEB System uses Web services to communicate with the L-ROC System. All device and operating parameters of every single L-ROC Room Controller are automatically synchronized with the LWEB-900 SQL database by the LWEB-900 client or the LWEB‑900 Master Device Manager. The parameters are available to all L-WEB client applications.

I/O Integration via Plug and Play

The L‑ROC Room Controllers can automatically integrate physical I/Os by using L-IOB I/O Modules. Up to 24 L-IOB I/O Modules can be connected through LIOB‑Connect, LIOB-FT, or LIOB-IP. All I/Os can be used by the L-ROC application and are also available via the Web interface of L-ROC. All configurations of the L-IOB Modules are stored on the L-ROC and loaded on demand into the L-IOB I/O Modules. Exchanging I/O modules is done without any configuration effort requiring only a few quick configuration steps.

Year Shade Progression

Especially in dense city areas, buildings can cast shadows on each other. In case a façade element is shaded by another building, sunblinds can be deactivated for better daylight harvesting. The high-performance L-ROC controllers allow to calculate a 3D model in dxf-Format of the building and its close-by neighbors. The model can be constructed using common 3D CAD software or can be derived from a Building Information Model. In case the scenery changes due to new constructions, only the new buildings have to be inserted in the model. The calculation can be done for each window individually or per shadowing zone.

IoT Integration

The IoT function (Node.js) allows connecting the system to almost any cloud service, either for uploading historical data to analytics services, delivering alarm messages to alarm processing services or operating parts of the control system over a cloud service (e.g., scheduling based on Web calendars or booking systems). Processing Internet information such as weather data in forecast-based control is also possible. Finally, the JavaScript kernel also allows implementing serial protocols to non-standard equipment.
