Automation Servers

An Automation Server is a Schneider Electric manufactured embedded device that generally serves as the lowest tier SmartStruxure server within the SmartStruxure solution. The Automation Server controls and supervises equipment, typically HVAC equipment. The Automation Server uses I/O modules with connected field devices, such as sensors and actuators, to do that.

Automation Server is based on the patented two-piece design. Each Automation Server consists of an electronics module and a terminal base.

The Automation Server is installed with the I/O modules on DIN rails in cabinets. The Automation 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 SmartStruxure 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 SmartStruxure 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 SmartStruxure device installed to the right (next terminal base in the chain).

For more information, see Terminal Bases .

Memory

The Automation Server has two types of memory:

128 MB SDRAM (for program execution)
4 GB flash (for storage)

If a power failure occurs, all important variables are automatically saved to the flash memory before complete shutdown. When power returns, this data retention function ensures that the Automation Server can continue to run with the correct set of values.

Supported Building Standards

The Automation Server natively communicates with three of the most popular communication protocols:

BACnet: The Automation Server directly communicates to BACnet/IP and BACnet MS/TP networks, which provides access to b3 devices and BACnet devices.
LonWorks: The Automation Server has a built-in FTT-10 port, which enables access to Xenta devices and LonWorks devices.
Modbus: The Automation Server natively integrates Modbus RS-485 master and slave 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.

Automation Server Communication Ports

The Automation Server has the following communication ports:

1 Ethernet 10/100 megabit port
2 RS-485 ports
2 LonWorks (TP/FT and RS-485) ports
2 USB host ports
1 USB device port
1 backplane I/O bus port

For more information, see Automation Server Communication Ports .

Reset Functions

There are three different types of reset for the SmartStruxure server devices: warm start, cold start, and DFU mode. Depending on the type of reset, the SmartStruxure server device can be reset using the reset button or a command from WorkStation.

For more information, see Reset Functions .

Communication Port Wiring

The wiring recommendations for the SmartStruxure server device communication ports apply to the wires and cables used for RS-485 communications, LonWorks communications, USB connections, and Ethernet connections. Always use the recommended cables and wires.

SmartStruxure Server Device Replacement Using Restore

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

Internal Configuration

All connectors of the Automation Server, except for the Ethernet connector, refer to signal ground as shown in the figure below.

action_zoom_plus_stroke

Figure: Automation Server internal configuration

The I/O bus in the terminal base provides the Automation Server 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 I/O module and the SmartStruxure server device.
