Enterprise Server

Introduction

Le serveur EcoStruxure Building Operation constitue le cœur du système et assure les fonctions essentielles, telles que la logique de contrôle-commande, l'enregistrement des tendances et la supervision des alarmes. Le serveur Enterprise Server collecte des données à l'échelle du site à des fins d'agrégation et d'archivage, et permet de centraliser l'administration par le biais de WorkStation ou WebStation pour EcoStruxure BMS, le système de gestion de bâtiment intelligent de Schneider Electric.

Caractéristiques

L'Enterprise Server constitue un point central de l'architecture EcoStruxure Building Operation, à partir duquel les utilisateurs peuvent configurer et surveiller l'ensemble du système.

Enterprise Server and Enterprise Central come with built-in support for modelling of the “digital twin” of the building, site, campus, and region using Brick Schema. WorkStation and WebStation provide enhanced human understandability through the additional context that is given to alarms and points through the “digital twin”. The required graph database is included in the installation packages. WorkStation can be used to create the model, or it can be imported using the graph database user interface.

L'Enterprise Server peut exécuter plusieurs programmes de contrôle en utilisant une variété de protocoles différents. Il gère les alarmes, les utilisateurs, la planification et l'enregistrement des tendances. Les données de l'Enterprise Server peuvent être soit affichées directement aux utilisateurs, soit transmises aux autres serveurs EcoStruxure BMS et équipements de terrain du site.

The entire site, including all of the field servers and their associated devices, can be accessed and configured through the Enterprise Server.

This overview of the site provides easier mass change engineering and data analysis. The Enterprise Server also aggregates the event and alarm data from all its associated field servers. Trend logs can be aggregated through the use of extended trend logs.

Unique to the industry, the EcoStruxure BMS servers have both Script and Function Block programming options. This flexibility helps assure that a suitable programming method can be selected for the application.

Alarms from multiple devices throughout the site, including field servers, are collected by the Enterprise Server for centralized logging, display, and management. Users can also view event logs and trend logs from multiple servers.

The Enterprise Server hosts the historical and configuration databases. These databases store current information, including trends, alarms, user activity, and property information. Alarms can trigger email, SNMP, file, or client notifications, which can include alarm, point value, or trend log data. Notifications can also be triggered periodically by schedules or other binary values.

EcoStruxure BMS servers can be configured to automatically store all historical data, trend log data, event log and audit trail data, in an external database. If data needs to be available for longer periods of time, an external log storage can be incorporated into the EcoStruxure BMS without the need for extensive engineering work. The supported databases are TimescaleDB, which is built on PostgreSQL, and Microsoft SQL Server. The data in the external log storage is available natively to the viewers built into the EcoStruxure Building Operation clients and to the built-in reporting functionality.

You can use the powerful Log Processor functionality for custom processing of trend data for viewing in charts, dashboards and for inclusion in reports. The Log Processor enables advanced calculations on one or multiple trend logs and point values.

Examples of advanced calculations:

• Energy usage normalization

• Virtual submeters and summaries

• Calculation of Mean Kinetic Temperature

• Unit conversions

• Average, maximum, and mini m um over custom periods

The output of the Log Processor can be saved in the database, including the External Log Storage or calculated automatically on demand.

Selected trend logs and the event log can be sent to AVEVA PI System directly without the need for intermediate storage or specialized PI System connectors.

The EcoStruxure BMS servers provide built-in functionality for basic reporting that can deliver reports in any text format and XLSX, without any dependencies to other external software. Reports for XLSX can be enriched by using advanced functionality such as formulas, conditional formatting, charts and sparklines.

Reports can be generated on schedule, on an alarm event or other custom conditions, and you can get the output delivered via email or written to file.

Using Enterprise Server and Enterprise Central, reports can be converted to PDF, and you can elevate the data security and traceability even further by using the optional add-on for automatically signing PDF reports with a digital certificate upon generation. This validates that the content has not been altered after the report was generated.

An EcoStruxure BMS provides a powerful permission system that is easy to manage, flexible, and adapts to all kinds of system sizes. The permission system provides a high standard of authentication. Authentication is done against the built-in user account management system , against Windows Active Directory Domains , or via SAML 2.0 single sign-on . The built-in account management system allows an administrator to establish password policies that meet stringent cybersecurity guidelines. When Windows Active Directory or SAML 2.0 authentication is used, the administration costs are lower because users do not have to be managed in multiple directories.

Il est important d'enregistrer plus que la simple activité. Dans une solution EcoStruxure BMS, toutes les actions sont enregistrées avec horodatage, nom de l'opérateur et la valeur qui a été modifiée.

Through any client, the user experience is similar regardless of which EcoStruxure BMS server the user is logged on to. The user can log directly on to an Enterprise Server to engineer, commission, supervise, and monitor the field servers with their attached Central IO modules, field controllers, and other field devices. For more information, see the WorkStation and WebStation specification sheets.

Une caractéristique essentielle de la solution EcoStruxure BMS est la prise en charge des normes ouvertes. L'Enterprise Server peut communiquer nativement les protocoles les plus populaires pour les bâtiments : BACnet (notamment BACnet/SC), client OPC UA, LonWorks et Modbus.

L'Enterprise Server communique directement avec les réseaux BACnet/IP. Il est référencé BTL en tant que BACnet Building Controller (B-BC), le profil de dispositif BACnet le plus avancé et en tant que poste d'opérateur BACnet (B-OWS). Cette compatibilité donne accès à une gamme étendue d’équipements BACnet, en provenance de Schneider Electric ou d’autres fabricants. Voir le catalogue de produits BTL pour obtenir des informations actualisées concernant les versions des logiciels de la liste BTL sur la page d'accueil de BACnet International. L'Enterprise Server peut également assurer la fonction de répéteur BBMD (BACnet Broadcast Management Device) pour faciliter la gestion de systèmes BACnet répartis sur plusieurs sous-réseaux IP.

The Enterprise Server and field servers support BACnet/SC applications as a BACnet/SC node, hub, and router. This allows the Enterprise Server and field servers to be in BACnet/SC networks and support applications that connect BACnet/IP or MS/TP networks with BACnet/SC networks. A major benefit of BACnet/SC is that it allows more secure transport of BACnet traffic and information between BACnet/SC devices over private and public networks without the need for BBMDs, VLANs, and VPNs, because the BACnet/SC protocol uses WebSocket technology and TLS 1.3 encryption. In addition, BACnet/SC uses certificate management to help ensure only those devices authorized to be on a BACnet/SC network can operate on that network.

OPC UA Client functionality is natively supported in Enterprise Server and field servers, enabling powerful and high-capacity integration of devices or systems that have OPC UA Server capability. OPC Unified Architecture (OPC UA) is a standard originating from industrial automation and process control that provides methods intended to provide improved security, performance, and engineering efficiency. With OPC UA Client support, the EcoStruxure Building Operation software can monitor and control a wide variety of devices or systems, from Schneider Electric as well as from other companies.

L'Enterprise Server fonctionne avec toute une gamme d'adaptateurs LonTalk afin de communiquer avec des réseaux LonWorks TP/FT-10. Le support natif LonWorks permet de prendre en charge directement des équipements LonWorks de Schneider Electric ou de fournisseurs tiers. Les réseaux LonWorks peuvent être installés et configurés via l’outil intégré LNMT (LonWorks Network Management Tool). Aucune application tierce n’est nécessaire. Pour une utilisation plus aisée, les plug-ins pour dispositifs LNS sont pris en charge. Ceci, permettant une configuration et un entretien des dispositifs LonWorks par Schneider Electric et d'autres prestataires. Les modes d'utilisation des plugs-ins des dispositifs LNS sont limités.

The Enterprise Server and field servers natively integrate Modbus RS-485 client and server configurations, as well as Modbus TCP client and server. This allows full access to third-party products and the range of Schneider Electric products that communicate on the Modbus protocol, such as power meters, UPS, circuit breakers, lighting controllers, and emergency lighting.

Modbus device types are pre-configured Modbus applications for quick and easy Modbus device integration in EcoStruxure Building Operation solutions.

L'Enterprise Server prend en charge l'utilisation de services web basés sur des normes ouvertes telles que SOAP et REST, pour la consommation des données dans la solution EcoStruxure Building Operation. Cela inclut l'utilisation de données entrantes de tierces parties (prévisions de températures, coûts de consommation énergétique) pour de déterminer les modes des sites, les calendriers et la programmation.

EcoStruxure Web Services, Schneider Electric’s Web Services standard, is natively supported in the EcoStruxure BMS servers. EcoStruxure Web Services offers extra features between compliant systems whether within Schneider Electric or other authorized systems. These features include access to semantic model, system directory browsing, read/write of current values, alarm receipt and acknowledgement, and historical trend log data. EcoStruxure Web Services requires user name and password to log on to the system.

The Enterprise Server and field servers support MQTT as an option for publishing data to, and receiving updates from, other systems. MQTT is a messaging transport protocol that with its small footprint, light bandwidth utilization, and simplicity, is ideal for M2M and IoT communication. The MQTT capability supports communication with any MQTT broker, for example, Amazon, Microsoft, Google or IBM.

The EcoStruxure BMS servers communicate using the networking standards. This makes installations easy, management simple, and transactions more secure.

• Adressage IP

• Communications TCP

• DHCP pour une configuration aisée de réseaux

• DNS pour une recherche d'adresses en toute simplicité

• HTTP/HTTPS - Accès Internet via des pare-feu, autorisant les accès distants sécurisés

• NTP (Network Time Protocol) pour la synchronisation horaire de l'ensemble du système

• SMTP/SMTPS avec prise en charge de l’authentification basée sur SSL/TLS pour envoyer des e-mails déclenchés par programmation ou alarme

• SNMP permet la réception des alarmes des applications dans des outils de gestion du réseau désignés

• Cryptage WebSocket Secure (WSS) et TLS 1.3 (applications BACnet/SC)

Communication between clients and the EcoStruxure BMS servers , and between EcoStruxure BMS servers, can be encrypted using Transport Layer Security (TLS ). The servers are delivered with a default self-signed certificate. Commercial Certification Authority (CA) server certificates are supported to lower the risk of malicious information technology attacks. Use of encrypted communication can be enforced for both WorkStation and WebStation access.
