Introduction
This topic serves to give you an overview of the components of a fully operational configuration created in IGSS Definition. While creating all these components, a number of files are created and updated in the configuration folders. Click here to get an overview of the folders and files in a configuration.
The configuration components
A fully operational configuration contains the following components. For a detailed description of any of the components, click its name.

break a configuration into logical units. One area is predefined, the Global area, but you can add as many areas as you see fit. Each area contains a number of diagrams, process components and graphs that belong together. Only one area can be active at a time. |
|
|
break an area into process diagrams which typically cover a specific section of the process. A diagram consists of a background showing the permanent components (tanks, containers, etc.) and connections (pipes, etc.) in the process and the dynamic process components (valves, motors, pumps, etc.) represented by symbols on the diagram. In many cases, it is beneficial to provide the operator with an overview diagram which contains references in the form of click-sensitive fields that take him to other areas, diagrams or graphs. The overview diagram will typically be the first diagram that the operator sees when he opens an area (specified using the Set Initial Display option in the Format menu). The diagram window is the most frequently used window in the supervision situation. |
|
|
give the operator direct access to a predefined graph showing values or states of a number of process components. Beside the predefined graphs, the operator can also view graphs by manually selecting a number of process components and then request a graph. |
|
|
show the value, state and alarm state of a physical component in the process. The process components are shown as symbols on the process diagram and the operator can instantly see the current value or state of the component and whether it is affected by an alarm situation (typically symbolised by a blinking symbol). |
|
|
speed up the configuration process and ensure consistency throughout the configuration. A template contains a number of properties shared by a number of process components. Once the template is defined, the process components are based on the template, reducing the task of defining a new component to assigning a unique name and specifying the precise PLC address. Templates can be defined for analog, table, counter and digital objects. The most useful type of template is the one for digital objects, because it allows you to define any number of states and commands and give them the names you like. Furthermore, you gain control of the individual bit sent to and from IGSS. |
|
|
eliminate the need of PLC programming in order to convert a set of values to another set of values. A scaling object can, for example, be used to convert values sent from the PLC as °F to °C, if the operator prefers that unit. |
|
|
describe an alarm situation for the individual object. You can, for example, define a low and a high alarm limit for analog objects. If one of these alarm limits are exceeded, an alarm will be raised in IGSS Supervise. The operator can then open the Alarm List and view the detailed alarm text which contains an alarm priority, a detailed description of the alarm situation and operator instructions. |
|
|
represent process components on process diagrams. IGSS comes with a predefined library of symbols, Symbols.v20, which contains the most commonly used symbols in a wide range of industries. The symbols are selected as part of the definition sequence. Beside these symbols, a number of other descriptors may be used to represent process components, for example, drawing objects (lines, rectangles, etc.), graphics files (*.bmp, *.wmf, etc.), Windows controls (command buttons, combo boxes, etc.), OLE objects or ActiveX controls. The appearance of these descriptors may be connected to values, states or alarms of the linked process component. |

provide you with easy-to-use objects which can easily be adapted to your own configuration. One of the system objects is the System object that monitors the disk capacity and printing status.
