3.2 Engineering Workplace / Plant Explorer
Engineering Workplace / Plant Explorer is the tool that is primarily used for 800xA system configuration. The Engineering Workplace is the workplace used for all project work done by application engineers.
The Project will exist in the Aspect Integrator Platform but the control part of it will use Control Builder as an aspect system for its configuration。 Therefore when a new project is created we work partly in the Platform and partly in the Control Builder。
NOTE! Before you start， make sure that the ‘System’ is ‘Up and Active’
3.2.1 What is a System？
A system is a collection of programs and services that are run together to support the HSI. At the very least there will be an Aspect server and a Connectivity server making up the system。
3.2.2 What is a Workplace？
This is the working environment for a particular group of people who might wish to access the system。 In a newly installed system there are 4 default workplaces provided, intended for various users.
· Engineering Workplace
· Operator Workplace
· Plant Explorer Workplace
· Two Screen Plant Explorer Workplace
In a delivered system there may be more. A delivered application is likely to have a workplace tailored to the requirements of the customer.

The main difference between the Engineering Workplace and the Plant Explorer Workplace is that only the Engineering Workplace allows you to use advanced tools such as Function Designer and Bulk Data Manager.
NOTE! The system extension “Engineering Base” must be loaded to have the Engineering Workplace available。

3.2.3 How to Start the Engineering Workplace
You can access the Engineering Workplace by right-clicking on “My ePlant” on your computer desktop and then select ‘Engineering Workplace：

You can also use the Start button to select “Workplace”:
Start | Programs | ABB Industrial IT 800xA | System | Workplace

The Workplace logon screen has two selection panes：
· The ‘System' selection pane
· The ‘Available workplaces' pane
In a typical plant there will be only one System available. This will be the system that was built for the application。
3.2.4 Browse the Aspect Directory
Plant Explorer is used to browse and navigate in the Aspect Directory。 It is used to create and manage Aspect Objects.

Plant Explorer is based on the concept of Windows Explorer。 When viewing a structure， objects are in the left-hand window (pane) and aspects of the selected object are in the right-hand window (pane).

3.2.5 Structures
The Aspect Object concept allows organization of objects and aspects into different structures， depending on which context is to be viewed。 Structures are the graphical representations of the relations that exist between different aspect objects.

Plant Explorer organizes the 800xA system into Structures that can be accessed from the pull-down menu in the upper left—hand window.

NOTE! The same object can be seen in different structures.

There are 19 structures by default. There are at least 5 structures that are either used for modeling your physical plant or are often used in operations. The use of these structures will vary from system to system depending upon the needs of the person（s） that are configuring and using the system。
The majority of time we use only a few of theses structures， which are marked in blue:
· Control Structure
· Functional Structure
· Location Structure
3.2.5.1 Context Menus
By right-clicking on an object， the corresponding aspects will appear. Each object has certain aspects available， which can be different from one object to the other。
Also the aspects have a context menu to handle the aspects themselves

3.3 Structures used for Application Engineering
These are the main application structures of the 800xA system。 These structures are primary structures, because it is assumed that most Application Engineers will perform most of their work within these structures.
3.3.1 Functional Structure
The Functional Structure describes the functionality of the plant. It is used to structure the plant into systems and subsystems according to how the plant equipment operates together。
By this it can also be used to organize displays， alarm sectioning and other functions that are related to the structure of the plant。

3.3.2 Control Structure
The Control Structure contains the networks and nodes that are used to control the process that is the equipment of the system。 It is also used to organize the process control environment in the system.
This structure contains control networks， control projects, applications， controllers, stations， different types of sub-objects (like I/O boards and process objects as well as signals assigned to different objects within this structure）。

3.3.3 Location Structure
The Location Structure (optional） is supplied to help the user identify the geography or location of the objects in the plant. This structure must be built with the knowledge of what buildings, rooms and locations that exist in the site.

3.3.4 Library Structure
The Library Structure is used to categorize and store reusable entities。
It contains all object type libraries and its versions. The object types of these libraries are stored in Object Type Structure.
It contains the templates for such object types as the Alarm and Event List configuration, History Logs, and Trends.

3.3.5 Object Type Structure
Almost all aspect objects are instances of an Object Type. The intent is to make it possible to create and efficiently re-use standardized solutions to recurring problems.
An example would be a control valve. Rather than create a new and unique Aspect Object for every valve in your plant， it would be more efficient to create a few valve types。 When you needed a particular solution， you would use an instance of one of your valve Object Types.
When you use an instance of that object type， the aspects that are pre-defined for that object type are automatically instantiated and associated with the new instance.

3.4 Structures used for Administration
3.4.1 User Structure
The User Structure holds the defined users and user groups allowed to work in the system。 You define user roles in the Configuration Wizard.
All users must have a related Windows user account. The user aspect primarily contains information about a user and what the user is allowed to do within the system (his user role).

3.4.2 Workplace Structure
The Workplace structure is used to define and create the layout of the screens for user interface to the system. This includes workplaces for operations， maintenance， management etc.
The workplace objects types of aspect that can be placed here are numerous， and they control the layout and function of a workplace, for example tool bars and menu items。

3.4.3 Service Structure
The Service Structure holds the services， their groups and providers, and the relations between these defined in a system.
A service is a global function in the network, and the objects and aspects in the Service Structure control the definition and deployment of the services.

3.4.4 Maintenance Structure
The Maintenance Structure is used to define and work on Backups， System Configuration Versions, and Synchronizations.

3.4.5 Additional Structures
Other structures that contain important information or may require a one—time configuration for the system include:
· Admin Structure
· Aspect System Structure
· Node Administration Structure
· Graphics Structure

3.4.5.1 How to Navigate between Structures
You can easily navigate from one structure to another， if the same object is used in several structures.

Just click on the structure aspect and it will lead you to the place where the object is located in the other structure.
NOTE! A good example is an object type， which is placed in the Object Type Structure and in the Library Structure。
3.5 Handling of Objects and Aspects
3.5.1 How to Add Objects
Adding a New Object to a structure is as simple as a right-click.

Select the Object type, give it a unique name and select “Create”。

The new object will appear in the structure at the level that it was created. In this instance, the new object was added at the root of the structure。 Any default aspects that are part of the object type will automatically appear in the aspect list。

3.5.2 How to Add Aspects
Adding a New Aspect to an object is also as simple as a right-click.

Select the Aspect type, give it a unique name and select “Create”.

The Alarm and Event List aspect has been added to the Reactor_11 object.
The main view of this new aspect is visible is visible in the preview pane. The user may toggle the preview pane (viewable or not） as desired.

3.5.3 Default Aspect for an Object
Each object may have one （and only one） aspect set as the default aspect。 By doing so, this will be the aspect that is automatically viewed in the preview pane while working in the Plant Explorer.
In an operator workplace context menu, it is the default aspect that is at the top of the aspect list. It is also the aspect that will be acquired when there is a left mouse click on the object。
NOTE! Often the default aspect is the Faceplate of an object like a motor or valve.

To set a default aspect for an object…
1. Right click on the desired aspect.
2. Select “Properties”.

3. Select the Aspect Details tab and check the box marked “Default aspect”。

4. Select Apply or OK

The Alarm and Event List is now set as the default aspect for the Reactor_11 object. If another aspect is set to default status after this one， then it becomes the default aspect. In other words, last aspect set to “default”, WINS。

3.5.4 Aspect Inheritance
Some aspect properties cannot be modified because the properties are inherited from the Object Type structure. Note that in the Inherited column， the value for the highlighted aspect is set to true.

To modify the aspect properties, you may Override the inheritance。

After selecting “Override"， the value in the Inherited column is now set to false and you may edit the aspect properties。
NOTE! Once override is selected it is not possible to revert to “inhereted”。

3.5.5 How to Insert Aspect Objects into other Structures
One of the time-saving features of the Aspect Object technology, is the ability to reuse objects in other structures。 You may have previously created an Aspect Object and defined the aspects required for it。 Now you find that you need that identical object in another structure.
This means that you can identify the characteristics of the object (aspects） once, and use that object wherever it is necessary.

In the following example， we have navigated to the root of the Functional Structure.
1. Right click on the Root。
2. Select “Insert Object”。

3. From the pull—down menu， navigate to the structure that has the desired object。
4. Select the desired object and select “Insert， Close”.

The Reactor_11 object （with all of it’s aspects) is now part of the Functional Structure.
3.6 Find Tool
The “Find Tool” provides fast access to one particular aspect or objects by clicking on the following icon：

In the “Find tool”， enter the name of an object or the path to an object as a search criteria and then search for the object that you are looking for. It is also possible to search for aspects.

NOTE! Use wild card searches, if you are uncertain of the exact name.

Use the “＊” character as a substitution for zero, or one or more characters， and the “？” sign to substitute exactly one character.

Find queries are defined in the Find Query Definition area in the Find Tool. This is the main input and user interface area of the Find dialog。

NOTE! Queries can be saved for further reuse.

3.6.1 Find Attributes
The search query can be defined more detailed by using additional Find Attributes。

In this example， you can specify to search in which structure。

3.6.2 Quick Find Tool
Navigating to items in Plant Explorer is performed by browsing the structures and trees. Another way is to use the Quick Find tool to get quick access to an object.
Quick Find searches for objects with the name that has been entered or selected in the list. If an object is found it will be selected in the list and in the Object Browser.

You can not search for Aspects with this tool.
NOTE!
