WattStopper LMSM Series: Network Segment Manager & Network Supervisor

Product Overview

The WattStopper LMSM Series Network Segment Manager (LMSM) and Network Supervisor provide comprehensive control, monitoring, and scheduling for Digital Lighting Management (DLM) systems. They are designed to manage DLM segment networks, offering global control and access to advanced features, enabling efficient lighting and plug load energy management.

The LMSM Segment Manager acts as a network controller, communicating with DLM local networks and LMCP panels. It supports standard and Human Centric Lighting (HCL) scheduling. The Network Supervisor is a PC server application that coordinates multiple Segment Managers and stores historical energy usage data, facilitating long-term analysis and reporting.

Key benefits include:

• Global control of DLM segment networks and access to advanced features.
• Support for third-party integration with Building Automation Systems (BAS) through BACnet/IP.
• Connectivity to DLM segment networks and PCs, LAN, or the Internet via Ethernet.
• Enables scheduling, power monitoring, and remote adjustment of devices on DLM local networks.
• Friendly browser-based user interface.
• Optional server-based network supervisor package for long-term energy-use data recording.

Description

The LMSM Segment Manager is a network controller designed to communicate with DLM local networks and/or LMCP panels. It provides control, monitoring, adjustment, and standard or Human Centric Lighting (HCL) scheduling functionality for networked DLM systems. The Network Supervisor is a PC server running similar software designed to coordinate control of multiple Segment Managers and store historical data.

Operation

The LMSM communicates with DLM local networks and panels over a BACnet MS/TP segment network. The LMSM-3E supports three direct-connected segment networks for up to 120 DLM rooms / 750 devices, while the LMSM-6E typically utilizes NB-ROUTERs to connect to up to 200 rooms / 1100 devices. The Segment Manager communicates over a TCP/IP connection to any device running a compatible web browser and is required for initial setup and configuration. Following setup, Supervisor software may be used for centralized control of multiple segments. A BACnet BAS may communicate with an LMSM via BACnet/IP, accessing an Export Table that exposes a selection of application-specific BACnet objects.

Features

• Communicates all DLM local network data and device settings via the segment network dataline.
• Secure browser-based UI uses SSL industry standard communications and can be accessed via direct TCP/IP connection, local LAN, or via the Internet.
• Allows remote changes to occupancy sensor and daylighting sensor settings in real time.
• Adjusts scheduling of normal and after hours.

Scheduling, Monitoring, and Adjustment

Users can easily monitor energy use via a dashboard that displays energy usage and alerts when a room or group exceeds normal usage. A configuration screen enables adjustment of DLM device parameters, including occupancy and daylighting sensor settings, load parameters, digital switch button configuration, and dimming parameters. Normal and after hours parameters can be set or adjusted, and users can create seven-day-repeating or calendar-event-based schedules. Additionally, power consumption may be viewed in real time for areas equipped with any DLM load controllers with built-in current monitoring. The software can also be used to create reports for maintenance and building administration.

Applications

The Segment Manager and Supervisor are ideal solutions for managing lighting and plug load energy use, and providing remote access to DLM local networks. They are suitable for schools, office buildings, and all applications that benefit from the ability to adjust settings and calibrations from a central location, as well as projects that require automatic reconfiguration of device settings based on a schedule. Both also enable demand response.

• Create standard and HCL lighting schedules. Schedules may be repeating seven-day, calendar-event based, or astronomic control.
• Allows real-time current monitoring of rooms and groups when using load controllers with current monitoring circuitry (e.g., LMRC-2xx or LMPL-201).
• Easy integration with BAS standard BACnet objects to represent DLM device settings and states.

Software Features

Dashboard

The Dashboard mode provides a graphic interface displaying real-time energy usage and a five-day energy-use history. Rooms can be grouped by location or custom criteria. Color-coded alerts indicate when a room or group exceeds normal usage based on predetermined targets. Both the browser-based Segment Manager UI and the Network Supervisor UI allow views of individual rooms, panels, and groups. The Network Supervisor enables long-term storage of historical data, which is not possible on Segment Managers alone.

Monitoring and Control

Key parameters for every DLM device are accessible and changeable via the web browser interface. Information is displayed in simple, easy-to-use trees with different options for viewing the DLM hierarchy.

User Interface (UI)

Screenshots demonstrate the user interface:

• Dashboard View: Shows energy usage graphs and data for rooms or groups, including total usage and current power draw.
• Schedule View: Displays scheduled lighting events in a calendar format, indicating days, times, and event types.
• Monitoring and Configuration View: Presents a hierarchical tree of devices, showing their status (e.g., Occupied ✔️, Unlocked), operating mode, and network properties.
• Demand Response Popup: A modal window allows users to manage Demand Response settings, with options to Disable ❌, Override, or Force overrides, along with explanatory text.

Event Scheduling

Both the Segment Manager and Supervisor enable the creation and editing of complex scheduled control for daily, weekly, monthly, or special events based on time of day or astronomical time. These schedules can be applied to standard and/or HCL lighting types and assigned to individual rooms or groups. The schedule display includes a chart of all currently saved schedules.

BACnet Integration

The BACnet export function exposes selected DLM data points as BACnet objects for access by a BAS or other BACnet-enabled application. Points available for export include occupancy state, load status, lighting power, plug load power, light level, and schedule mode.
