Hosts In EC-NETAX, any EC-BOS controller or computer running the AX framework is referred to as a “host.” In AX, hosts may be seen on a Navigation (Nav) Tree as objects connected to a network with an IP address and name: Under the host, each EC-BOS controller will have a PLATFORM and a STATION icon that allows a user to connect to either via an active session. Programming blocks can be added to the Programming Sheet from the Code Library (as code snippets) or Toolbox. BACK TO MENU

Local vs. Remote Hosts The computer on which AX is running is called the LOCAL Host. It is referred to as “MyHost” in the Nav Tree. All EC-BOS controllers or other computers on which AX is running are called REMOTE hosts. LOCAL HOST (LAPTOP) REMOTE HOST (EC-BOS) BACK TO MENU

What’s a Station? A station is the main unit of server processing and engineering in the Niagara architecture. A station database is defined by a single .bog file called a “config.bog." Stations are booted from their config.bog file into a single Virtual Machine (VM), or process, on the host machine. config.bog There is usually a one-to-one correspondence between stations and host machines (Supervisors or EC-BOSes). However, it is possible to run two stations on the same machine if they are configured to use different IP ports. BACK TO MENU

What’s a Station? The primary parts of a station include components and services. A Station is the combination of a database, a web server, and a control engine. The station either runs on a Web Supervisor PC or an EC-BOS controller. DATABASE CONTROL ENGINE WEB SERVER BACK TO MENU

What’s Included in a Station
A station runs the components of the AX Framework and provides the access for client web browsers to view and control these components. Such components might include: Objects that represent controllable equipment such as: Fans/pumps Boilers Chillers Coils Valves Schedules that drive equipment, set setpoints, enable events, etc. Trending data collected based on intervals or value changes Alarms that get generated periodically based on exceeding limits Graphics that allow owner/operator access using a web browser BACK TO MENU

Station Representation in AX
In EC-NET-AX, a Station is represented by a Fox icon in a tree structure called a “Nav Tree.” NAVIGATION (NAV) TREE Toolbox Elements Click each of the following Toolbox Elements below to find out more. To communicate with a Station, it must be in a running status and accessible on the Nav Tree. BACK TO MENU

What is a Platform? The Platform is the name for everything that is installed on a EC-NETAX host that is not part of an engineered EC-NETAX station. The Platform interface provides a way to address all the support tasks that allow you to setup, support and troubleshoot an EC- NETAX host. SETUP SUPPORT TROUBLESHOOT BACK TO MENU

What is a Platform? In EC-NETAX, when you open a platform connection to an EC-NETAX host (whether an EC-BOS controller or Supervisor), that host’s available platform functions (as a toolset) are listed in the platform’s Nav Container View, as shown here > > > > > > > > > Toolbox Elements Click each of the following Toolbox Elements below to find out more.

Platform View Exceptions – 1
Each platform function has its own Workbench view (plugin); you access it by simply double-clicking on it. Most of the same platform views exist whether a platform connection to an EC- BOS controller or an AX Supervisor, with some of the following exceptions: If you connect to the local (My Host) platform on your laptop, some platform views appear to be missing – they have no application when working on your laptop—instead, you use Windows Explorer. For example: Distribution File Installer File Transfer Client Software Manager Station Copier 2 BACK TO MENU

Platform View Exceptions – 2
For any Windows-based platform, a User Manager view is available. This view is not available if the platform is a QNX-based EC-BOS or a Linux-based Supervisor. In AX-3.7 and later, some platforms may have a Certificate Management view. This view appears only for a host licensed for SSL (secure connection). An EC-BOS with an installed WiFi option has two related platform views: WiFi Configuration and WiFi Certificate Manager. BACK TO MENU

AX Architecture Types The following architecture types are presented to give you an appreciation of how the AX framework is constructed for software, communication and drivers. Additionally, typical network architectures are included. It is NOT intended as an exhaustive treatment. Software Architecture Communication Architecture This diagram comes directly out of the AX Help system – it represents the software architecture of the platform and station generically. The PLATFORM consists of the: Hardware Host – either a PC (laptop) or JACE (EC-BOS) The Operating System (O/S) – either Windows or Linus (for a PC) or QNX (for an EC-BOS) The JAVA Virtual Machine (JVM), which is layered on top of the O/S. A Java virtual machine (JVM) is an abstract computing machine that enables a computer to run a Java program. The JVM provides a layer between the hardware and its operating system and the Niagara software, known as the Niagara run-time environment (NRE). The Niagara Runtime Environment (NRE) – hosted by the platform-specific JVM, the framework uses the Java VM as a common runtime environment across various operating systems and hardware platforms. The core framework scales from small embedded controllers to high end servers. Modules – on top of the NRE are the Niagara modules.

AX Communication Architecture
This diagram illustrates the following concepts: The platform daemon (niagarad) (Port 3011/5011) is used to facilitate communications (such as station saves/backups), logins, etc.) between EC-NET-AX (shown as “Workbench”), a Supervisor platform and an EC-BOS platform. The Fox Service (Port 1911/4911) is used for all network communication between EC-BOS stations as well as between the EC-NETAX engineering tool and EC-BOS stations. The Web Service (Port 80/443) is used to determine the port usage and authentication methods of the station's web server, There are typically four different programs (or processes) associated with a Niagara AX system. These programs and their network communication are illustrated via the Communications Diagram: Station: is the Niagara runtime - a Java VM that runs a Niagara component application. Workbench: is the Niagara tool - a Java VM that hosts Niagara plugin components. Daemon: is a native daemon process used to boot stations and to manage platform configuration such as IP settings.

AX Basic Structure AX's design goal is to integrate cleanly with all networks and protocols. The AX software suite implements a highly efficient adaptation of the JavaBean component software model and Internet technologies to provide true interoperability across a wide range of automation products. The AX object model can be used to integrate a wide range of physical devices, controllers, and primitive control applications including Lonmark profiles, BACnet objects, and legacy control points. The AX architecture supports future enhancements by allowing legacy systems to be brought forward, where they can readily adopt new standards, solutions, and applications. BACK TO MENU

Fox Protocol Proprietary TCP/IP protocol used for station-to-station and Workbench-to-station communication The AX framework includes a proprietary protocol called Fox which is used for all network communication between EC-BOS stations as well as between the EC-NETAX engineering tool and EC-BOS stations. Fox is a multiplexed peer-to-peer protocol that sits on top of a TCP connection. The default port for non-secure Fox connections is The Fox Service is the management tool (or process) in AX that allows configuration of the Fox protocol. BACK TO MENU

Standard protocol used by web browsers to access web pages from a station
HTTP Protocol HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page. The other main standard that controls how the World Wide Web works is HTML, which covers how Web pages are formatted and displayed. HTTP is called a stateless protocol because each command is executed independently, without any knowledge of the commands that came before it. This is the main reason that it is difficult to implement World Wide Web sites that react intelligently to user input. This shortcoming of HTTP is addressed in a number of technologies, including Java, JavaScript and cookies. The Web Service is the management tool (or process) in AX that allows configuration of the HTTP protocol. BACK TO MENU

niagarad.exe monitors Ports 3011/5011.
Proprietary protocol used for EC-NETAX-to-daemon communication Niagarad Protocol The niagarad protocol uses the platform daemon, which is a compact executable written in native code (it does not require the Niagara core runtime environment (NRE), or even a Java virtual machine (JVM)). The platform daemon is pre-installed on every EC-BOS controller (even as factory-shipped), and runs whenever the EC-BOS boots up. Also, a Niagara host's platform daemon monitors a different TCP/IP port for client connections than does any running station. By default, this is port 3011 (non-secure) or 5001 (secure). The Niagara Service is the management tool (or process) in AX that runs the platform daemon. niagarad.exe monitors Ports 3011/5011. BACK TO MENU

Niagara Daemon (niagarad)
niagarad.exe a native daemon process used to perform functions such as: Booting/starting/saving stations Performing station backups Managing platform configurations (such as IP settings) Authenticating access to platforms and stations Upgrading AX software BACK TO MENU

On Windows platforms (laptops), the daemon is run in the background as a Window's service. On QNX platforms (EC-BOSes), it is run as a daemon process on startup. Windows Task Manager BACK TO MENU

The most common way to access daemon functionality is through EC-NETAX. A connection to the daemon is established using the “Open Platform” command, which opens a Platform session to the remote machine for that specific release of NiagaraAX. BACK TO MENU

Each instance of the niagarad.exe is unique to the version of AX that it’s associated with. You cannot run more than a single instance of the platform daemon. As a result, it is possible to be running a platform daemon of a different Niagara release than the EC-NETAX software that is currently active on your PC. For example, if you are working in EC-NET-AX and need to work in EC- NET-AX , you must first stop the currently running platform daemon and start the platform daemon for the other version of AX. Stop this one. Start this one. BACK TO MENU

Starting another platform daemon automatically stops the one previously running. Starting this one. Stops this one.

Connecting to Platforms & Stations
Platforms and Stations are typically accessed using unique icons displayed on the Nav Tree: For the My Host (Local Host – PC) icon, the PC name is displayed instead of the IP address. Also, the My Host icon is always displayed first at the top of the Nav Tree.

Platform Connections–Overview
A platform connection is different than a station connection. When connected to a EC-NETAX platform, EC-NETAX communicates (as a client) to the host’s platform daemon (also known as “niagarad” for Niagara daemon), a server process. Unlike a station connection that uses the Fox protocol, a client platform connection ordinarily requires full Workbench (that is, using the “Web Workbench” applet), meaning it is unavailable using a standard Web browser.
