The Vijeo Citect Environment

Configuration Environment

The configuration environment consists of a set of tools (applications) you use to build the runtime system. The configuration environment is centred on the Citect Explorer, which is used to create and manage projects.

You use projects to organize your configuration data into logical, well organized, groups. You can design your system to use one or more projects at a time, depending on the modularity of your plant or system.

The configuration environment consists of the Citect Explorer, Project Editor, Graphics Builder, Cicode Editor, and Equipment Editor.

Setting Up Communications

Communicating with I/O Devices

Vijeo Citect can communicate with many types of control or monitoring I/O Devices - including PLCs (Programmable Logic Controllers), loop controllers, bar code readers, scientific analysers, Remote Terminal Units (RTUs), and Distributed Control Systems (DCS).

Vijeo Citect communicates directly with the I/O Devices in your plant or factory, allowing data transfer to or from the device and supervisory control of the system.

The Express Communications Wizard enables you to quickly set up communication with a new or existing I/O Device. Each Vijeo Citect project will need to have at least one I/O Server defined for it to communicate to I/O Devices. Each I/O Device will need to be set up in Vijeo Citect with an appropriate communications protocol and settings and any interface boards and communications ports in the computer will also have to be defined.

Stepping through the Express Communications Wizard defines the:

I/O Server names

interface Boards in the computer

communications Ports on the boards

I/O Devices attached to the ports

Variable Tags

Variable Tags define the data that is transferred between the I/O Device and the Vijeo Citect I/O Server. Each Variable Tag is defined with a unique name, a data type, an address and an associated I/O Device.

Suggested Exercises


Use the Express Communications Wizard to set up an External I/O Device that uses the Generic protocol.

Set up some Digital, Integer and Real tags.

Use Excel to add more tags and save the variable tags file using the save_dbf.xls macro.

Set up your computer as a Stand-alone Server.

Graphics

Pages

A Vijeo Citect runtime system usually comprises a series of graphics pages that display on your computer screen(s) and provide a "window into the process." You can design your pages to provide your operators with control of an area (or all) of your plant. Your graphics pages can also display the status of your plant by using various graphical items known as objects.

The graphics pages are one of the principle components of a Vijeo Citect system. They are the interface to plant operators, and can be designed to display data as well as to accept operator input.

True Color Support

True Color support allows Vijeo Citect users to create graphically rich display pages more easily by supporting 24-bit colour.

True Color is supported for all animation objects and static objects, including page backgrounds, imported images, symbols, metafiles, and bitmaps. The flash rate of flashing colours defaults to 1 second, and is user-configurable via a .ini file parameter.

Suggested Exercises


Create a new page and add these objects

o Ellipse

o Circle

o Rectangle

o Square

o Symbol

o ActiveX

Add dynamic properties to the objects so that they will display the values of tags

Create a fill rectangle

Edit colours using the Swap Colours and Adjust Colours tools

Commands and Controls

Allow Operators to Interact with the System

Commands and controls allow operators to interact with the Vijeo Citect runtime system. There are three types of commands and controls:

Slider controls that an operator can use to change the values of analog variables.

Touch commands that an operator can issue by clicking on an object with the mouse.

Keyboard commands that an operator can issue by typing instructions on the keyboard.

You can assign privileges and areas to commands and controls and you can also send a message to a log each time an operator issues a command.

Suggested Exercises


Define a key sequence on a numeric object to change the value of an integer.

Add a slider to an object to change the value of a real tag.

Add a toggle command to an object to change the state of a digital tag.

Equipment

Equipment

In a SCADA system, the term Equipment is used to refer to logical groupings around specific objects. Being object-oriented, Equipment definitions allow you to create a hierarchical architecture for a project that can be used to logically reference the machinery or processes being monitored.

Equipment is now the focus of early project design. The project design flows logically from the layout of physical equipment or plant in your system. By defining equipment first, you can create a hierarchy of tags for each plant line or process, making it easier to monitor each production process and group tags in a way that better represent configuration of the plant.

The textual representation of a hierarchy is achieved by the use of a dot, or period (".") to separate the items and their level in the hierarchy. For example if you were to create a structure of a production line in a factory called 'Factory1" which has 3 production lines each identified as Line1, Line2, Line3. Each production line has 2 Assembly stations identified as Assy1 and Assy2. Each assembly station has 2 conveyer belts identified as Convey1 and Convey2.

Convey2 could then be uniquely identified in the system as:

Factory1.Line1.Assy2.Convey2

Suggested Exercises


Create an equipment hierarchy in your project.

Genies and Popup Pages

Genies

Usually each graphical object on a graphics page is configured individually. With a genie, you can combine several related objects into a group and store the group in a genie library (similar to a symbol library). The genie can then be used as if it was a single object (pasted, moved, resized, etc.) and the elements of the genie are then configured collectively.

All types of graphic objects and their configuration data can be stored with the genie. For example, you can define a genie for a start/stop controller (with a start button, a stop button and an indication lamp), and use the same genie for all equipment (pumps, conveyors, etc.) that use that type of controller. When you use the genie, you will only need to specify the information that is unique to that particular pump or conveyor.

Popup Pages

Popup pages are dynamic pages which you can use to pass information when the page displays in the runtime system. You can use them for pop-up type controllers for a process or a single piece of plant floor equipment. You could also configure a graphics page with several pumps, and use a pop-up controller for each of the pumps on the page.

In most cases where you use a popup page, you use it in association with a genie.

Suggested Exercises


Create a new Genie in the graphics page using the Equipment.Item reference.

Check that the genie substitution has occurred correctly.

Create a popup page using a Dynamic Association function. Call the popup page from a genie using the Ass() and WinNewAt() function.

Link a genie to an equipment type.

Devices

Transferring High Level Data

A Device is an interface used to transfer high-level data (such as a report, command log or alarm log) between Vijeo Citect and other elements (such as a printer, database, RTF file, or ASCII file) in your Vijeo Citect system. Devices are similar to I/O Devices in that they both allow Vijeo Citect to exchange data with other components in your control and monitoring system.

Suggested Exercises


Set up a device that will log operator commands into a text file. Configure the device to create seven history files and to roll over at midnight.

Events

Events Trigger an Action

You can use an Event to trigger an action such as a command or set of commands. For example, an operator can be notified when a process is complete, or a series of instructions can be executed when a process reaches a certain stage.

You can run an event by the following methods:

o Automatically at a specified time and period

o Automatically when a trigger condition becomes TRUE

o Automatically when a trigger condition is TRUE at a specified time and period

Events must be enabled for events to run. Use the Computer Setup Wizard (Custom setup) to enable Events. If using Vijeo Citect on a network, you can process events on any Vijeo Citect computer (or all computers).

Suggested Exercises


Define an event to change the value of an integer every five seconds to a random number between 70 and 75.

Define an event to toggle a digital tag when the value of an integer tag drops below 80.

Alarms

Alarm Types

Protection of valuable plant equipment is a central feature of your Vijeo Citect system. The Vijeo Citect alarm facility, when it is configured, constantly monitors equipment and alerts operators of any equipment fault or alarm condition.

Vijeo Citect supports two types of alarms:

Hardware Alarms

Vijeo Citect continually runs diagnostic routines to check all peripheral equipment, such as I/O Devices. Faults found are reported automatically to the operator. This facility is fully integrated within Vijeo Citect – no configuration is necessary.

Configured Alarms

Unlike hardware alarms, you must configure the alarms that report fault conditions in your plant (for example, when a tank level is too high or when a motor overheats).

Suggested Exercises


Define a digital alarm, an analog alarm, an advanced alarm and a time-stamped alarm, each in a different category.

Define in your alarm category how to show the state of the alarm on the alarm page, and the millisecond value of the timestamped alarms.

Use the standard alarm logging device to log alarm state changes.

Create alarm, hardware, disabled and summary alarm pages.

Put buttons on the alarm page, to filter by alarm category. (Use AlarmSetInfo())

Put a button on the alarm page, to allow filtering by alarm name. (use AlarmSetQuery())

Configure an Alarm server to publish Alarm tags, and use the alarm as tags to show the threshold of the analog alarm on a page.

Create a system keyboard command to disable an alarm. Observe what happens with the acknowledge state when you re-enable an alarm (via another keyboard command).

Process Analyst

Values in Graphical Format

A visual representation of past and current activity improves understanding of the plant’s performance. With a trend graph, you can display the values of a variable (or process) in graphical format. As these values change over time, the graph moves across the page so that the latest values are always displayed.

You can also scroll back through historical data to display past values of the variable (or process). Historical data collection continues even when the display is not active. You can switch between pages without affecting trend graphs. You can trend any single variable or Cicode expression. You can display any number of trends on the screen simultaneously, and display the trends of up to eight variables in any trend window.

Vijeo Citect provides three types of trends: Periodic, Event, and Periodic Event.

Active X Control

The Vijeo Citect Process Analyst is an ActiveX control designed to allow operators to view trend data from a Vijeo Citect trend server, and alarm tag data from a Vijeo Citect alarm server. The Process Analyst provides a visual means to analyse and compare trend data (real-time and historical) in a more intuitive manner than Vijeo Citect's trend templates.

Suggested Exercises


Define a trend tag of each different trend type (periodic, event, periodic event) with a 1s sample time, and 10 history files of 10 minutes each.

Calculate the amount of storage space that will be needed for those trends

Create a new page and add a Process Analyst Active X object to the page.

Add Trends and Alarms to the Process Analyst

Save the View

Drag the Analyst pane to the left and right to view values through time.

Add another instance of the same trend tag to the Process Analyst. Unlock the pens and compare the value of the trend to the values of the same trend at another time.

Page Management

Menu Configuration Tool

Menu entries are created in 4 levels for display in pages based on the Sxw_Style_Include project.

Menu configuration is saved in the PageMenu.dbf file in the project directory.

Suggested Exercises


Add a new menu page to the menu system using the Menu Configuration Tool.

Create a Process Analyst page and move the page into another menu.

Change your Home button to display a page of your choice.

Adjust the display order of menu entries.

View the PageMenu.dbf file in Excel to understand everything stored there.

Reports

Report Plant Status

You can request regular reports on the status of the plant and reports to provide information about special conditions in the plant. Reports can be run on a request basis, at specified times, or when certain events occur (such as a change of state in a bit address). Reports can also include Cicode statements that execute when the report runs.

Suggested Exercises


Make an rtf report, use WordPad as the report format file editor, and send the output to an ASCII device. Show the values of the three tags and the current time and date in the report.

Create page with a button to run the report.

Create another page to show the generated rtf report.

Create scroll buttons to view the report.

Knowledge base, article Q1213: Error 'Maximum report size exceeded'


Security

In Built Security

For large applications, or applications where access to certain processes or machinery must be restricted, you can build security into your system. You can then restrict access to commands that should not be available to all your operators; for example, commands that operate specialized machinery, acknowledge critical alarms, or print sensitive reports.

You can assign a separate password to each of your operators (or class of operators), that must be entered before the operator can use the system.

Suggested Exercises


Define 2 users, one with global privilege 1 and one with global privilege 2.

Create a page with two buttons to change the value of the integer tag. Configure one with privilege one and one with privilege 2. Create also a button to call the UserLoginForm(). Test this page.

Now assign this page to area 1. Copy the page, and assign the other page to area 2.

Can both users view both pages?

Add a user that has no global privilege, but only privilege 1 in area 1. Test which pages he can see, and which buttons he can operate.

Create two analog alarms, one in area 1 and one in area 2. Create a standard alarm page and add graphic objects that allow you to trigger the two alarms.

Test which alarms user 1, 2 and 3 can see on the alarm page.
