VTScada helps you create powerful Supervisory Control and Data Acquisition (SCADA) programs.
All features are built into the core product - there are no extra parts to install.(1) VTScada provides instant recovery, full-system failover, hardware independence, online configuration and all of the tools that you expect in a full-featured SCADA program.
Everyone who is upgrading a legacy application to the current version should review the topics in the chapter, Moving to the Current Version.
For sites that log a large number of values, there are steps that you can take to improve performance significantly. Refer to the topic: Optimize Your Configuration
- Maximum of 50 input / output (I/O) tags.
Tags that read and write from hardware, and any that you create yourself, count towards the license limit. All other types including ports and drivers may be created without limit.
- No Alarm Notification by phone, email, text or pager.
Configuration options for alarm notification are enabled as most may have other purposes, but you cannot send an alarm notification to remote operators using VTScadaLIGHT.
Visual and audible alarm indications on the current workstation are an entirely different feature and are enabled in VTScadaLIGHT.
- Maximum of one Internet client connection.
Be sure to read the relevant security notes before enabling Internet client connections to your application.
- Cannot be used as a server or client for an application that also runs on workstations with a full VTScada license.
- Maximum of 10 free VTScadaLIGHT installations by any individual or organization, after which more licenses are available for purchase.
Use the filter button to limit the range of the search. If no results are returned, check that you are searching on All Files, rather than a filtered subset. If there are still no results, try a synonym for the term. Searching for a term used by some other SCADA program will often return the closest equivalent concept used in VTScada.
If you enter more than one word into the search field, "and" is assumed. (For example, Tag Browser is equivalent to Tag AND Browser, but not necessarily "Tag Browser".) If you want to specify "or", put that word into your search. For example, a search for CIP DRIVER will return just over 20 results while a search for CIP OR Driver will return over 300 topics.
Menu links in a page are part of that page. If you search for something that's in a topic title, you will also get the pages that link to that title. This is sometimes useful for catching related information.
The search engine ignores certain commonly used words. For example, a, an, the, of, to, be, you, your, when, however, for, that, can (and more). If your search results are not successful, trim out some of the less important words.
"s" at the end of the word will have no effect on the number of results returned, but might sometimes affect the result ranking. "Driver" and "Drivers" will return the same topics.
Use the following tools to control the search:
|Search for a phrase.||Wrap the string in quotes.||"Create a report"|
|Search for any of several things||OR |
| (pipe symbol)
|"CIP driver" OR "DNP3 driver"|
"CIP driver" | "DNP3 driver"
|Search for two or more specific strings.||AND|
+ (plus symbol)
|"CIP driver" AND "DNP3 driver"|
"CIP driver" + "DNP3 driver"
|Search for a match that does not contain a word. Note that your phrase must include one word to search for. You cannot search for NOT TAG to get ever topic that doesn't include the word "tag".||NOT|
^ (caret symbol)
|Combinations||( )||widget & ("Analog Status" OR "Analog Input")|

(1)Features are activated or not according to the license key that you have purchased. Adding features means only changing the license key, not integrating new software.
Developers use tags to represent hardware in VTScada. Tags are designed to work like building blocks so that any type of physical system can be represented depending on how the tags are configured.
- Communication tags tell VTScada where to find the hardware and how to talk to it. I/O tags represent information being collected by the hardware and allow operators to write values out to the equipment.
- Alarm tags (and alarms built into I/O tags) tell you when operating conditions go outside of defined bounds.
- Historian tags record values from all alarms and from selected I/O tags, for later reporting.
- Pages provide the display screens for information collected from hardware. Some are built in, such as the alarm display, trend viewer, reports, notes, and more. Most, you will create for your unique situation. Drawing tools are provided so that you can create clear and realistic display pages without limit.
- Security features control who can do what within an application. Rules can be created for roles based on job-descriptions, allowing you to create privilege sets that can be applied to many operators. You can limit the scope of rules so that operators with the same role can access only those controls that relate to the area where they work.
- Server lists let you easily configure backup servers for fail-over, and can be used to distribute tasks between computers in large systems. The built-in Internet server allows operators to monitor values and acknowledge alarms via a web interface or a mobile device. They can even receive and acknowledge alarms by SMS text message.
- This guide contains information for people who use existing applications (Operate...) people who build applications (Build...), people who manage and update applications (Manage...) and for power-users who use the VTScada programming language to create their own development tools such as Wizards. (Program...). There is also a tutorial to show you how to build an application (Tutorial...)
- VTScada has its own programming language and uses its own set of terms. Use the Glossary to translate from VTScada-speak to terms that you're familiar with.
- The Search feature provides snippets from each match found, helping you decide which topic is most relevant to what you are searching for.
- Press F1 at any time in VTScada to open context-sensitive help for the task you are working on.
