Capabilities of Vijeo Citect

●SCADA

SupervisoryControlAndDataAcquisistion

Key point is ‘Supervisory’ – the plant should still be able to run on PLC control only

●Since v6.10, the SCADA product has been released under ‘dual-brand strategy’ of Vijeo Citect and CitectSCADA in order to be both a Schneider-branded product and also maintain a familiar name for existing loyal customer base. The software is essentially identical.

5Schneider Electric

Configuration Environment●Three windows...

● Citect Explorer – for browsing projects and project items

6Schneider Electric

Configuration Environment● Citect Explorer – ...and also for creation of new projects, plus backup and

restore of existing ones.

7Schneider Electric

Configuration Environment● Citect Explorer – ...and for running the Computer Setup Wizard

8Schneider Electric

Configuration Environment●Citect Project Editor – for accessing and editing project configuration (non-graphical)

9Schneider Electric

Configuration Environment●Citect Project Editor – ...and for packing and compiling the project after changes

●Packing removes deleted records

●Compiling takes the information from project configuration .dbf (dBase3) files and copies it to files .rdb (runtime date base files) for the runtime to use.

10Schneider Electric

Configuration Environment●Citect Graphics Builder – for creating and editing graphical elements such as

templates, pages, symbols, genies


Configuration Environment●A lot of settings, including those adjusted by the ‘Computer Setup Wizard’ are

in the citect.ini file. Edit it with the ‘Computer Setup Editor’ or a text editor - C:\ProgramData\Schneider Electric\Vijeo Citect 7.20\Config\citect.ini


Graphics

●Create a new page with Graphics Builder ‘File’ | ’New’●Many templates are available to base your page on (or you can create your

own templates!)


Graphics

●On your new page, add a numeric object and select the tag for it to display


Graphics

●For your object, go to the ‘Input’ | ‘Keyboard Commands’ tab to add the ability to write a value to the tag


Graphics●Save the page and compile the project

●At runtime you will be able to read the value of and write a new value to your tag


Communication to PLCs

●Easiest way to configure communications to PLCs is to use the Express I/O Device Setup wizard

●This wizard can be used for many protocols/devices



●For example, select ‘Schneider Electric’ > ‘OPC Factory Server’ > ‘OFSOPC’



●You will be prompted to enter the i/o device address. In the case of OFSOPC this is the PLC alias as shown in OFS


Communication to PLCs●The process is similar for other protocols. For example, to connect with an M340 with

Modbus TCP, you will be prompted to enter the PLC’s IP Address

●The ‘Protocol Help’ button will take you to the Driver Help for the protocol in use



●Driver Help is an essential reference for checking or changing configuration, adjusting driver parameters, troubleshooting, etc


Communication to PLCs●To troubleshoot a PLC

connection, check if the device is offline. Or is it online but writes and/or reads with some or all tags are not working?

Check that it is online by

1. Opening the kernel for the i/o server (requires ‘Kernel on Menu’ option enabled in Computer Setup Wizard)

2. Opening the i/o devices (unit) window and scrolling (page down) to the i/o device of interest - check ‘unit status’



●Check the driver error and verify its meaning in the Vijeo Citect Help or Driver Help. This may give you more detail on the problem.

• For errors codes 0x01 to 0x22: see Vijeo Citect Help: Technical Reference > Vijeo Citect Reference Information > Error Messages > Protocol-Specific Errors.

• For errors codes > 0x22: check the Driver Help (for the protocol in use), the SCADA Knowledgebase and device documentation.


Variable tags●You can add variable

tags manually with the form. (Check Driver Help for the protocol in use for data types and addressing details.)

●You can add tags automatically by enabling the linked option in the Express I/O Device Setup wizard or using Citect Explorer ‘Tools’ | ‘Import tags’.


Alarms●Vijeo Citect includes several types of alarms to suit different data types and

requirements


Alarms●Current ‘active’ alarms (on and/or unacknowledged) are shown the the ‘Active Alarm’ page


Alarms●A history of alarms is shown in the ‘Alarm Summary’ page, whose length in

either time or number of entries is configurable


Trends

●Add trends using the form


Trends●Trends are displayed at runtime in the Process Analyst


Trends●You can also export trend

data to CSV or DBF files using

●Functions TrnExportCSV and TrnExportDBF

●The TrendReader tool on the citect.com Toolbox


Reports●Vijeo Citect can create reports that include snapshots of data at the time the

report is run. The report can ●overwrite each time●append continuously to a single file●be written to a new file each time or at set intervals

●Reports can be any one of several file types●DBF●Plain text●Rich text●HTML


Reports●Reports are configured in the reports form and using a report format file


Reports●The output format of the report is configured in a system device.

●Consult the Vijeo Citect Help for information on configuring reports, format files and system devices.


Reports●An HTML report...


Cicode●Cicode functions are detailed in the Vijeo Citect Help

●They can be run in ‘command’ or ‘expression’ fields


Cicode

●If the function is being used to perform some action, it would normally be used in a ‘command’ field, such as in the touch command of a button.


Cicode

●If the function is being used to return some value, it would normally be used in an ‘expression’ field, such as in the display value expression for a text object


Cicode

●Many built-in functions are written in the Cicode Editor. You can also use this to write your own.


Cicode●The Vijeo Citect Help includes an extensive section on cicode


Multi-language projects

●To mark text for translation, use the syntax @(text)


Multi-language projects●After compilation, a DBF file for the language includes all text marked for

translation. This is then edited by the user to include the translated text

●At runtime, the displayed language can be changed using the function SetLanguage()

●See multi-language section of the Vijeo Citect Help for full details
