Capable of coordinating traffic from above and below its location, the AS-B server can deliver data directly to you or to other servers throughout the site. The AS-B server can run multiple control programs, manage built-in I/O, alarms, and users, handle scheduling and logging, and communicate using a variety of protocols. Because of this, most parts of the system function autonomously and continue to run as a whole even if communication is interrupted or individual EcoStruxure BMS servers or devices go offline.

The AS-B server comes in eight models that offer two different sets of I/O point count and I/O mix.

AS-B servers with “H” in the product name are equipped with a display for output override.

AS-B servers with “P” in the product name are hardware only. An AS-B software package needs to be purchased separately. For more information, see section “Software bundles”.

AS-B servers with 36 I/O points have the same small footprint as AS-B servers with 24 I/O points.

The AS-B server offers a mix of I/O point types that match a wide variety of HVAC applications. Most of the I/O points are universal inputs/outputs, which are highly flexible and can be configured as either inputs or outputs.

AS-B servers with 24 I/O points have the following types:

• 12 Universal inputs/outputs, Ua type

• 4 Universal inputs/outputs, Ub type

• 4 Digital inputs

• 4 Relay outputs

AS-B servers with 36 I/O points have the following types:

• 20 Universal inputs/outputs, Ua type

• 8 Universal inputs/outputs, Ub type

• 4 Triac outputs

• 4 Relay outputs

The universal inputs/outputs are ideal for any mix of temperature, pressure, flow, status points, and similar point types in a building control system.

The universal inputs/outputs can be configured to read several different types of inputs:

• Digital

• Counter

• Supervised

• Voltage

• Current (Ub only)

• Temperature

• Resistive

• 2-Wire RTD temperature

• 2-Wire RTD resistive

As counter inputs, the universal inputs/outputs are commonly used in energy metering applications. As RTD inputs, they are ideal for temperature points in a building control system. As supervised inputs, they are used for security applications where it is critical to know whether or not a wire has been cut or shorted. These events provide a separate indication of alarms and events in the system.

For all analog inputs, maximum and minimum levels can be defined to automatically detect over-range and under-range values.

The universal inputs/outputs are capable of supporting analog outputs of type voltage outputs. Therefore, the universal inputs/outputs support a wide range of devices, such as actuators.

Only devices with safe extra low voltage equipment (SELV/PELV) inputs/outputs should be connected to the AS-B server universal inputs/outputs.

The digital inputs can be used for cost effective sensing of multiple dry contact digital inputs in applications, such as equipment status monitoring or alarm point monitoring. As counter inputs, digital inputs are commonly used in energy metering applications.

The relay outputs support digital Form A point types. The Form A relays are designed for direct load applications.

The triac outputs can be used in many applications to switch 24 VAC on or off for external loads such as actuators, relays, or indicators. Triacs are silent and do not suffer from relay contact wear.

For applications that require more I/O resources, the SpaceLogic IP-IO modules provide a versatile mix of I/O points for any application. For more information, see the SpaceLogic IP-IO Specification Sheet.

AS-B servers with “H” in the product name are equipped with an LCD display and keys to support manual override control of analog and digital outputs. This function allows you to manually override the outputs for testing, commissioning, and maintenance of equipment.

The override status is readable through EcoStruxure Building Operation WorkStation and WebStation, enabling precise monitoring and more reliable control.

The device has a built-in power supply designed to accommodate 24 VAC or 24 VDC input power. The main AC/DC input (L/+ and N/-) is galvanically isolated from the electronics. This removes the risk of damage due to earth currents and permits the input power to be wired without concern for AC polarity matching.

AS-B 服务器有多个端口，它可以与各种协议、设备和服务器通信。

AS-B 服务器有下列端口：

• 两个 10/100 以太网端口

• 一个 RS-485 端口

• 一个 USB 设备端口

• 一个 USB 主机端口

The first Ethernet port is dedicated to the site network. The second Ethernet port is fully configurable. The second port can be configured to extend the site network so that various devices and clients can be connected. Another option is to configure the second port as a separate network, which means that the port can host a private network. If the second port is not used, it can be disabled.

USB 设备端口允许您使用 Device Administrator 升级 AS-B 服务器并与其交互。

借助 USB 以太网适配器，您可将笔记本电脑连接至 USB 主机端口并运行 Device Administrator、WorkStation 和 WebStation 来对 AS-B 服务器进行升级、配置和访问。USB 主机端口也可用于为 Wireless Adapter - Advanced 提供电源和通信。

Through Wireless Adapter - Advanced connected to the host USB port, Zigbee ^TM wireless connectivity can be enabled for the automation server. The automation server can extend its point count through the Zigbee wireless network and bring flexibility in your applications. The automation server equipped with the adapter is together a Zigbee Certified Product that is compliant with Zigbee 3.0. For more information on the adapter and supported wireless devices, see the Wireless Adapter - Advanced Specification Sheet.

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 or against Windows Active Directory Domains. The built-in account management system allows an administrator to establish password policies that meet stringent cybersecurity guidelines. When Windows Active Directory is used, the administration costs are lower because users do not have to be managed in multiple directories.

经由任何客户端进入的用户所获得的体验都是相似的，无论用户登录到哪个 EcoStruxure BMS 服务器。用户可直接登录到 AS-B 服务器来设计、调试、管理和监视 AS-B 服务器以及它的内置 I/O 模块和现场总线设备。更多信息参见 WorkStation 和 WebStation 规格表。

EcoStruxure BMS 的基础之一是支持开放标准。AS-B 服务器可以与一些最流行的建筑标准进行本地通信：BACnet（包括 BACnet/SC）、OPC UA Client 和 Modbus。

AS-B 服务器可与 BACnet/IP 和 BACnet MS/TP 网络直接通信。AS-B 服务器是 BTL 认证的 BACnet 楼宇控制器 (B-BC)，是最为高级的 BACnet 设备设置文件。该功能提供访问施耐德电气和其他供应商提供的各种 BACnet 设备的能力。在 BACnet International 首页查看 BTL 产品目录了解 BTL 清单固件修订版本的最新详情。AS-B 服务器还可充当 BACnet 广播管理设备 (BBMD) 来促进横跨多个 IP 子网的 BACnet 系统。

The Enterprise Server and automation servers support BACnet/SC applications as a BACnet/SC node, hub, and router. This allows the Enterprise Server and automation 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 automation 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.

The Enterprise Server and automation 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, and lighting controllers.

Modbus device types are pre-configured Modbus applications for quick and easy Modbus device integration in EcoStruxure Building Operation solutions. For information on the Modbus devices supported using Modbus device types, see the document EcoStruxure Building - Modbus Device Integration - Supported Device Brochure.

AS-B 服务器支持基于开放标准（比如 SOAP 和 REST）的 Web 服务的使用，以消耗数据到 EcoStruxure BMS 中。在 Web 上使用输入的第三方数据（温度预测、能源成本）来确定站点模式、日程安排和编程。

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 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 automation 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.

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.

From EcoStruxure Building Operation version 5.0.3 and later, 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.

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.

The automation server has a 4 GB eMMC memory, which is used, for example, for the application, historical data, and backup storage. Users can also manually back up or restore the automation server to a storage location on a PC or network. Through the Enterprise Server, users have the ability to perform scheduled backups of associated automation servers to network storage for even greater levels of protection.

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

• IP 寻址

• TCP 通信

• DHCP，用于轻松地配置网络

• DNS，用于简捷地查找地址

• HTTP/HTTPS，用于通过防火墙接入互联网，实现远程监控

• NTP（网络时间协议），用于整个系统的时间同步

• SMTP/SMTPS 支持基于 SSL/TLS 的身份验证，可发送时间表或报警触发的电子邮件讯息

• SNMP，用于网络监测和指定网络管理工具中的应用程序报警接收

• WebSocket Secure (WSS) 和 TLS 1.3 加密（BACnet/SC 应用程序）

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.

For protection from excess current that could be produced by field wiring, follow these instructions:

• Connect RET terminal number 4 or 5 to a common chassis/signal ground rail in the control panel using a size 2.5 mm² (13 AWG) or larger wire. The wire must have a current rating greater than or equal to 16 A.

• AS-B servers with 24 I/O points have more RET terminals for connection of I/O returns, so the common chassis/signal ground rail is optional and may not be needed.

• Individual 24 VDC power sources to the field must be current limited to maximum 4 A for UL compliant installations, and maximum 6 A in other areas.
