A Constantly Growing SCADA Solution

In addition to major software version updates, our permanent team of programmers and engineers regularly releases service updates with enhancements, bug fixes, and new features.

Version 11.3 New Features

Support for IPv6 Addressing

  • ISPs have limited IPv4 addresses left.
  • IPv6 provides better security and network capabilities.
  • Is included as a Standard Component of VTScada.*t


Alarm Notification using Twilio®

Voice telephony alarm notification functionality will be supported using Twilio, a Web-based Communications Platform, as an alternative to using a voice modem.  This can benefit those that want to use voice when you don’t have phone lines.

  • VTScada Alarm Notification System includes an interface to Twilio**.
  • Works in hosted applications.

IEC Driver

Supports open standard for connecting to a broad class of devices from around the world.  IEC 60870-5 is a collection of standards produced by the International Electrotechnical Commission, or IEC, to provide an open standard for the transmission of SCADA telemetry control and information.  Includes time stamping and Report by Exception.  VTScada can also act as an IEC slave (virtual PLC) with this driver.

OpenID Connect 

OpenID Connect is a standard for user-authentication. If enabled in VTScada, operators will be able to connect to the VTScada Anywhere client using their OpenID Connect credentials. This may be useful at sites where a user must logon once, then access several business applications throughout their day without needing to logon again. It can also provide enhanced security through the use of two-factor or multi-factor authentication. Refer to the OpenID Foundation website for further information.


Additional 11.3 Enhancements

  • The Sites, Map, and Operator Notes pages now each have their own dedicated system privilege. Old applications will have their Operator and Logged Off users updated with the new privileges as each application is activated, and any users not inheriting from those roles will also be updated. Any applications which have been updated with new privileges will not be updated again, and thus they can be removed from any users or roles that were automatically given privileges after the update. New applications will include the new privileges as part of the Operator role only.
  • Event records in the alarm history for unknown username login attempts now show the attempted username.
  • The Alarm Page can now display the text of acknowledged alarms using their priority color rather than just black or white.
  • A new application hook has been added, AlarmAckAllHook, that is called whenever the Ack All or Ack Shown buttons are clicked.
  • ROC Driver TLP definitions may now be added or overridden at the application level.
  • New TextEncode() function was added which encodes text as UTF-8.
  • System library function has been added for JSON encoding, System.JSON_Encode().
