The AS-P server offers enhanced processor performance, increased memory size, dual Ethernet ports, and high-speed USB interfaces. The AS-P server is a Schneider Electric manufactured embedded device that generally serves as the lowest tier EcoStruxure BMS server within the EcoStruxure BMS. The AS-P controls and supervises equipment, typically HVAC equipment. AS-P servers use Central IO module with connected field devices, such as sensors and actuators, to do that.

AS-P servers are based on the patented two-piece design. Each AS-P server consists of an electronics module and a terminal base.

The AS-P server is installed with the Central IO modules on DIN rails in cabinets. The AS-P server electronics module uses a W1 enclosure. Power is supplied through the terminal base backplane.

Electronics Modules

The electronics module is the main component of SpaceLogic devices that are based on the patented two-piece design. The electronics module is installed on a terminal base, which constitutes the second component of the device.

For more information, see Electronics Modules .

Terminal Bases

The terminal bases are used for SpaceLogic devices that are based on the patented two-piece design. The terminal base provides the I/O bus to the electronics module installed on the terminal base as well as to the SpaceLogic device installed to the right (next terminal base in the chain).

For more information, see Terminal Bases .

AS-P Server Models

The AS- P server comes in four models that offer support for different functions .

The AS-P-S and AS-P-NLS models are hardware only. An AS-P software package needs to be purchased separately. For more information, see the AS-P Specification Sheet.

Memory

An AS-P server has two types of memory:

  • 512 MB DDR3 SDRAM (for program execution)

  • 4 GB eMMC memory (for storage)

If a power outage occurs, all important variables are automatically saved to the eMMC memory before complete shutdown. When power returns, this data retention function helps ensure that the AS-P server can continue to run with the correct set of values.

Supported Building Standards

The AS-P server natively communicates with three of the most popular communication protocols:

  • BACnet: The AS-P server directly communicates to BACnet/IP and BACnet MS/TP networks, which provides access to MP and RP controllers, b3 BACnet devices, and BACnet devices. The AS-P server also supports BACnet/SC applications as a BACnet/SC node or BACnet/SC router, which allows the AS-P server to be in BACnet/SC networks and support applications that connect BACnet/IP or MS/TP networks with BACnet/SC networks.

  • LonWorks: The AS-P server has a built-in FTT-10 port, which enables access to Xenta devices and LonWorks devices.

  • Modbus: The AS-P server natively integrates Modbus RS-485 client and server configurations, as well as IP client and server. This integration provides access to devices that communicate on the Modbus protocol, such as power meters, circuit breakers, and lighting controllers.

Note:

The AS-P server models AS-P-NL and AS-P-NLS do not support LonWorks.

AS-P Server Communication Ports

An AS-P server has the following communication ports:

  • 2 Ethernet 10/100 megabit ports

  • 2 RS-485 ports

  • 2 LonWorks (TP/FT and RS-485) ports (not available on the AS-P-NL and AS-P-NLS models)

  • 1 USB host port

  • 1 USB device port

  • 1 backplane I/O bus port

For more information, see AS-P Server Communication Ports .

AS-P Server Screw Terminals

There are pluggable screw terminals at the top of an AS-P server.

For more information, see AS-P Server Screw Terminals .

AS-P Server LEDs

There are several LEDs on the front panel of an AS-P server.

For more information, see AS-P Server LEDs .

Reset Functions

There are four different types of reset for the automation servers: warm start, cold start, reset, and reset to DFU mode. Depending on the type of reset, the automation server can be reset using the reset button or a command from WorkStation.

For more information, see Automation Server Reset Functions .

Communication Port Wiring

The wiring recommendations for the communication ports on the automation servers, BACnet/IP devices, RP controller expansion modules, and Operator Display devices apply to wires and cables used for RS-485 communications, LonWorks communications, USB connections, Ethernet connections, sensor bus connections, room bus connections, and RP controller Modbus network connections. Always use the recommended cables and wires.

For more information, see Communication Port Wiring .

AS-P Server Software

Before you engineer an AS-P server, install the AS-P server software on the server using Device Administrator. The software is not pre-loaded on the AS-P servers.

For more information, see Installing AS-P or AS-B Software .

Automation Server Replacement Using Restore

Backup and Restore helps assure that automation server data can be restored to a replacement automation server in the event of detected failure, or to the same automation server in the event of data loss. As a precaution, you back up your automation servers regularly so that you can use the most current backup to restore the automation server data to a replacement automation server. You also configure the new automation server to match the name and the network settings of the replaced automation server so the system can identify this automation server when online.

For more information, see Automation Server Replacement Using Restore .

Internal Configuration

All serial communication ports of the AS-P server module refer to signal ground as shown in the figure below.

AS-P server internal configuration

Note:

The AS-P server models AS-P-NL and AS-P-NLS do not have LonWorks (LON) communication ports.

The I/O bus in the terminal base provides the AS-P server module with power and an address.

The address value in the I/O bus is increased by one for each terminal base. The I/O bus also enables RS-485 communication between the Central IO module and the automation server.
