The LROC-800 Room Controller extends LOYTEC’s L-ROC system with a rich blend of wired, wireless, and electrical interfaces. It is designed for advanced single-room automation applications and scales up to 3 rooms or room segments. Its core feature is a Bluetooth Mesh (SIG) interface for integrating Bluetooth Mesh sensors, luminaires, and other actuators. The device targets the need for cabling reduction in both, new buildings and retrofit scenarios. The LROC-800 Room Controller also 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 and adapted to changing requirements during the project with little effort. Integral parts of the L‑ROC system are a web-based room operation; via an LWEB‑802/803 dashboard and the automatic generation of graphics for the L‑VIS / L-PAD Touch Panel for local operation.
Our room controllers provide all common interfaces and a large number of physical I/ Os for room automation projects. KNX devices are integrated via the KNXnet/ IP interface. DALI lamps and DALI sensors are connected to the DALI interface with an integrated DALI power supply. Up to 16 SMI sunblind motors connect to the SMI interface. L-STAT room operator panels can be connected to the LSTAT port. The port can also be used for BACnet MS/TP devices or generic Modbus RTU/ASCII devices. Dual Ethernet ports allow daisy chaining of L‑ROC controllers ina ring topology and provide BACnet/ IP, LON/ IP, Modbus/ IP, KNXnet/ IP and OPC communication. The LROC-800 has a built-in WLAN interface. 3 TRIACS (0.5A), 4 Relays (10A) and 12 universal inputs outputs (IO) connect various physical inputs and outputs. Our room automation library provides pre-built function modules for all lighting, heating, cooling, ventilation, and sunblinds. Built-in TLS encryption ensures secure operation of the room automation system.
Flexible Room Concept for Room Automation
A room segment is the smallest individually controllable entity in the L‑ROC System. The L‑ROC Library provides a set of functions for every room segment including:
• Lighting control with constant light controller
• Sunblind control with angle adjustment and year shade progression
• Temperature control for heating, cooling, and ventilation
• Occupancy detection
• Window monitoring and window contact
The LROC-800 Room Controller can control 3 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 e.g. processing meter data.
Rooms can be created in any size by moving, installing, 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.
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 or a WIFI 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 configured 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. The built-in VPN function provides for simple VPN setup and secure access to remote sites. The LTE-800 interface enables wireless access to remote sites through a mobile carrier.
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 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, smartphone (by LWEB-APP), or tablet PC running Android or iOS.
Integration of the L-STAT Room Operator Panel
L-STAT room operator panels can be integrated via RS-485 interface. In addition to the attractive, modern design and intuitive operation, L-STAT provides a range of features to individually increase the room comfort.
Internal sensors measure temperature, humidity, dew point, occupancy, and the CO2 content of the air. There is also the possibility to control room functions via an IR remote control. Standard pushbuttons and external temperature sensors can be integrated through additional inputs.
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 XML‑DA or OPC UA.
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. Controllers can be replaced from the database with a backup without user interaction.
L-STUDIO
L‑STUDIO is the world’s first IEC 61499 based room automation system. Any room function can be realized with L‑STUDIO in a distributed system of L‑ROC devices.
We call this new approach in automation “Cloud Control”. In a cloud of L‑ROC devices, all automation functions are mapped automatically to physical hardware. The object-oriented design method allows the efficient reuse of previously implemented functions. In the graphical development environment of L‑STUDIO, areas are created from room segment with just a few mouse clicks. The areas are interconnected to floors and multiple floors form a building. The entire building application is automatically distributed to the L‑ROC Controllers installed in the building.
New functions can be added to the room segment objects after initial configuration. These new functions can be applied individually or to all room segment objects very easily. Comprehensive debugging and watch functions allow for complete building troubleshooting. An extensive library of functions is provided for heating, ventilation, cooling, lighting, sunblind control, and security. With the integrated L‑VIS/ L‑WEB Configurator, graphical pages for L‑VIS Touch Panels and L‑WEB applications can be customized.
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 or Node-RED) allows connecting the system to almost any cloud service, either for uploading historical data to analytics services, telemetry using MQTT, 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 in primary plant control.
