Terminology

Term Description

Aspect An aspect is a description of some properties of a real world entity. The properties described could be mechanical layout, how the object is controlled, a live video image, name of the object etc. In the Process Portal A is an aspect residing in an Aspect Object. Some examples of aspects are circuit diagram, process display and control logic.

Aspect Category

A specialization of an aspect type. For example, the aspect type Graphic Display includes the categories Overview, Group and Object Display.

Aspect Object Type

An Aspect Object type defines certain characteristics that are shared between several Aspect Object instances, such as basic set of common aspects. This makes it possible to create and efficiently re-use standardized solutions to frequently recurring problems. For example, rather than building an Aspect Object from scratch for every valve in a plant, you can define a set of valve types, and then create all valve objects as instances of these types.

Aspect Objects

A computer representation of a real world entity like a pump, a valve, an order or a virtual object like a service. This computer representation is implemented by the Process Portal A. An Aspect Object works like an information container for it’s aspects.

4


Aspect Server

A server that runs the central functions of the Aspect Object architecture, such as Aspect Directory, Structure and Name Server, Cross Referencing, File Set Distribution, etc.

Aspect System

A software system, which implements one or several aspect types by providing one or several aspect system objects.

Camera An analogue CCTV camera that provides a composite video signal, PAL or NTSC

Connect Product

Connectivity components, uploader, supporting aspect systems (e.g for the configuration), and graphical elements, faceplates, Aspect Object Types, etc., bundled together to provide the integration of a certain type of devices into the IndustrialIT system.

Faceplate A faceplate is an aspect that provides a graphical representation of a certain aspect object, with presentation of certain properties related to the object, and mechanism for operator interaction such as on/off, increase/decrease, etc.

Industrial IT ABB’s vision for enterprise automation.

Industrial IT System

A computer system that implements (part of) the IndustrialIT vision. Process Portal A is an example of such a system.

IP-Camera A digital camera that provides video over Ethernet networks.

Node A computer communicating on a network e.g. the Internet, Plant, Control or IO network. Each node typically has a unique node address with a format depending on the network it is connected to.

Plant Explorer

An application that is used to create, delete and organize Aspect Objects and Aspects within the Process Portal A. The plant explorer organizes the Aspect Objects in structures according to functionality, location etc. You can also use it to browse and search the structures of the plant.

Process Object

A process concept/equipment e.g. valve, motor, conveyor or tank.

Process Portal A

IndustrialIT System Product containing functionality for efficient control and supervision of an automated process. Key functions are presentation of graphics, process dialogs and presentation of alarms and trends.

PTZ A function of a camera to Pan/Tilt and Zoom its optical unit

Structure A hierarchical tree organization of Aspect Objects. Each structure is used to define a certain kind of relation between Aspect Object. The functional structure defines how a function can be divided into sub functions, the location structure defines how different objects are located within each other. The control structure defines how functions are executed by tasks, controllers etc. An Aspect Object can be located in several structures, for example both in a functional structure and in a location structure.

5


System Extension

A system Extension consists of one or more applications that is bundled as an extension to one or several existing System Product(s). A System extension can only be installed if (one of) the corresponding System Product(s) has been installed previously.

Videoplate A Videoplate is a Faceplate look a like, including similar functionality as a Faceplate. The Videoplate is created with Aspect object development methods.

View An Aspect can have several ways to be presented depending on the task performed, like viewing or configuration. Each presentation form is called a view.

Workplace 1. User interactive functions that are combined for a particular use, e.g, Operator Workplace. 2. A node that runs one or several workplace applications.

System Overview

The VideONet Connect package is installed in the 800xA system, each workstation that will present video needs to have the VideONet Connect installed to be able to connect to the cameras. The video stream will be a unicast point-to-point connection between the Workstation and the video server.

VideONet system

VideONet is a video handling system that can be used standalone or as a video integration platform in comprehensive information management systems, process control systems or alarm handling systems. The VideONet system can consist of an arbitrary combination of servers and clients. The system offers a standardized structure for treatment and presentation of video and related data from different types of video/surveillance related data-sources like Analogue cameras, IP-cameras, Audio communication, Video analyze data etc.

The video server can have one or more plugins installed to interface different types of video sources. In the example below the server must have plugins for analogue video capture, IP-video capture, the serial control bus for the analogue PTZ camera, some IP based PTZ control interface and possibly a plugin for video recording.

For information on the VideONet system see the document “VideONet Guidelines”

Product Overview

VideONet Connect

The VideONet Connect product is a system extension to the 800xA system. VideONet Connect extends the functionality of the 800xA system with VideONet aspects for managing and control of video cameras connected via a VideONet Server. The VideONet Aspects which are a part of the VideONet Connect gives you the following functionality:

• Connection to a VideONet Server

• Video camera Graphic Elements for presentation in 800xA Process Displays

• Video camera Videoplates for configuration, recording and log

7


Figure 1 System Overview

The video server provides a unified functional interface to the client API installed with the VideONet Connect, this enables the system to be extended with other camera types or interfaces just by installing new plugins on the server side.

Dimensioning the system

Before setting up your integrated 800xA-VideONet system it is important that you have considered some performance issues regarding the network- and CPU load that the video streams will require from the system. If you use more than a few cameras the recommendation is to use a separate network of the following reasons:

• Lower risk of disturbances in the process network. • Video is a real bandwidth consumer; 15-20 IP cameras can fill a 100 Mbit net.

8


The setup of the system is as follows: Camera to Server:

• All IP cameras send data to one or a few VideONet servers (continuously if you are recording). Calculate 1-4 Mbit/s per video stream (depending on camera, format, frame rate etc.)

Server to Client:

• A video server streams the requested/presented video streams to the 800xA workstations.

• Calculate 3 Mbit/s per video stream. Note that the video stream goes directly between the video server and the client aspect. It does not generate any load on any of the 800xA servers.

In a site with 40 cameras and 5 clients watching one camera each continuously, you have a worst case scenario of 160Mbit/s Camera>Server traffic and 15Mbit/s Server> Client traffic.

Heavy video usage example

In a site where the video presentation will be used extensively and or continuously a solution with dual network cards in the workstations with a separate connection to the video network is recommended. This will make the network traffic in the plant network shielded from the traffic in the video network. See configuration example below:

Figure 2 Heavy video usage system

9


Light video usage example

In a site without IP-cameras and where the use of videoplates in the workstations is infrequent, it is acceptable to connect the video server to the plant network. See configuration example below:

Figure 3 Light video usage system

Note that each open videoplate in “Super fast” frame rate (25 pictures/sec.) will cause a constant stream that uses 2.5 – 3 Mbit/s on the plant network. Also consider the possibilities for future expansion, it will probably be a lower cost to pull two parallel networks initially than to install an extra network at a later time when it is necessary. For more information about performance and network load of the VideONet system, please see the VideONet manuals.

Section 2 – VideONet Connect Configuration

VideONet Object Type and Aspect overview

VON Basic Camera, Object type

The VON Basic Camera object type includes a number of 800xA basic aspects plus the specific VideONet aspects: Camera Videoplate, Reduced Control and Camera Icon. This object type is especially design for video cameras that do not have the PTZ functions i.e. video cameras that only presents a fixed area. As a rule you shall only add this kind of object type to your 800xA structure when the camera shall treated as a “stand alone” in the 800xA structure i.e. is not connected to an existing object instance in your 800xA structure.

VON Extended Camera, Object type

The VON Extended Camera object type includes a number of 800xA basic aspects plus the specific VideONet aspects: Camera Videoplate, Reduced Control and Camera Icon. This object type is especially design for video cameras that do have PTZ functions. As a rule you shall only add this kind of object type to your 800xA structure when the camera shall treated as a “stand alone” object i.e. is not connected to an existing object instance in your 800xA structure.

VideONet Camera Videoplate, Aspect

The VideONet Camera Videoplate is available in the Basic and the Extended VideONet objects as well as in the 800xA aspect structure. The Camera Videoplate aspect is used for presentation and control of a camera view, a Videoplate can be configured to present any camera available via the VideONet Server. Whether the videoplate will include control functions or not depends on the functions of the connected camera. A Videoplate example is found below:

Section 3 – Operation

Use VideONet Camera Videoplates

The VideONet Videoplates are the control interface for the 800xA operator. Via the Videoplate you can see the camera view of the configured camera but you can also control the camera if such functions are available for the camera. Functions that are not available for the camera will be dimmed i.e. not accessible. Control functions that are available will be highlighted and possible to control. Below you can find a typical Videoplate in an extended view i.e. all available functions are presented:

Figure 15 Extended Videoplate view

The Videoplate can be called up from the process display via, for example, a VideONet Camera Icon.

20


Use VideONet Extended Control

The VideONet Extended Control aspect is only available in the 800xA aspect structure. The VideONet Extended Control aspect is used to get fast access to several different cameras and camera views available via the VideONet Server. An example of the Ext Ctl aspect is found below:

Figure 16 VideONet Extended Control

21


Disturbance Indications

If the video flow ceases, the text: “VIDEO LOSS” will be superimposed on the last received frame, in alternating, red and black letters.

The conditions for this indication are: . Figure 17 Video loss

- The aspect has received at least one video frame

And

- The VideoTimeOut (seconds), has passed since the last frame

Possible faults: (in descending probability)

- If only from one camera on a server with more than one camera connected; Power failure, Cable damage, Camera fault, Videocapture HW fault, Codec error

- From all cameras on a server; Network error, Video timeout to low (on a slow network connection), Server power failure, Videocapture HW fault, Server crash, Codec error

22


Section 4 – Use cases

Scalability / Flexibility

The scalability of the VideONet system is one of the key factors. It is possible to build system solutions ranging from one video source to hundreds of thousands of video sources. All software parts are building blocks that can be pieced together in a number of different ways. Parts of a large system can be set up as local sites with local management, while allowing centralized supervision and control (or even override) over the whole system.

In a complex solution even bandwidth demands and video encoding technology can be determined on a per-client level allowing for high quality/flow on broadband connections AND low bandwith/framerate on weaker connections simultaneously.

A standard installation (Analogue cameras)

The composite video signal from each camera is connected to the video inputs on the VideONet servers. Each server can handle up to16 video signals. “Handle” in this case includes; Digitizing, Compressing, Recording and Transmitting. Each camera can be movable, Pan/Tilt/Zoom, the control commands are normally sent on a separate RS422/485 bus connected to a serial port on the server.

Figure 18 Analogue standard solution

The VideONet Client is optional, it can be used to present fixed or patrolling video independent of the actions in the 800xA system and without loading any video over the plant network.

23


A standard installation (IP-cameras)

The IP-cameras must be connected to the Video network or to a network that is routable from the Video network. The VideONet servers will connect to the cameras to retrieve live images at the requested frame rate. Each server can handle up to 32 IP-cameras. “Handle” in this case includes; Connecting, Retrieving, Recording and Transmitting. Each camera can be movable, Pan/Tilt/Zoom, the control commands are normally sent on the same network connection as the video, but an alternative set-up with fixed IP-cameras mounted on RS422/485 controlled Pan/Tilt heads is supported.

Figure 19 IP-camera standard solution

The system above also describes the optional redundancy solution where VideONet servers 3&4 act as “Hot-spares”. Each camera is configured with sever 1 or 2 as “Primary” and with server 3 or 4 as “Secondary”. In case of failure of a primary server the image will automatically be routed through the secondary server after a configurable timeout.
