SCADA Alarm Notification

Optional Component

Critical SCADA alarm information, anywhere, anytime.

Today’s SCADA operators are too busy in the field to have time to sit looking at screens all day waiting for problems to occur. When alarms happen, the system needs to be able to get that information to the right person as soon as possible no matter where they might be.

SCADA Alarm Notification

The VTScada® Alarm Notification System (ANS) transmits alarm information anywhere via text-to-voice phone calls, SMS text messages, emails and pagers. Dial into your application using your application security account to check levels, acknowledge alarms, change setpoints, or send commands to equipment.

Built-In is Better

VTScada’s unique integrated approach to alarm notification vastly reduces integration time and ensures tight compatibility over the entire life of your SCADA system no matter what version you are running. Add ANS to any VTScada Runtime or Development Runtime license by simply updating your VTScada software key. The ANS shares the same tag and alarm databases as the VTScada application.

Note: Alarm and event management is part of every VTScada application. The built-in SCADA alarm notification features described on this page are optional.

Leave No Alarm Unacknowledged

When an alarm goes unacknowledged for a user-defined period, VTScada won’t stop until it finds an authorized person to acknowledge it. The system begins working its way through rosters of up to 30 contacts each. A contact is a combination of a staff member and a method of notification such as SMS text message, email, or over the phone via text-to-speech voice engine.

SCADA Alarm Notification Rosters

This means you can create a contact for your cell phone and another for your home phone. Each method allows the user to acknowledge the alarm and stop VTScada from sending further notifications. Configure any number of rosters for the whole application or specific functional areas. Roster activations are recorded as events in the alarm history.

Dial-In Phone Access

Dial in from anywhere to log in and use the auto-generated spoken menu’s system to hear system values (e.g. well levels), perform control actions (e.g. start pump 1) and receive or acknowledge a list of alarms.

Crystal Clear Text-to-speech

VTScada 11.2 adopted the Microsoft® Speech API (SAPI). In addition to providing the latest in text-to-speech technology, SAPI simplifies our licensing and significantly reduces the size of the VTScada installer.

  • Voice Modem Support – VTScada should work with any standard voice modem. Though we cannot guarantee the compatibility of third-party modems across all Windows operating systems our engineers have provided the following comments on modems that they have used or have been used by our customers. Their comments can be found on our VTScada Support Forum.
  • Advanced Modem Management – VTScada collects modems from all application servers into a single pool. VTScada searches this pool, rather than a particular server, for an appropriate data or voice modem to use when sending alarms.
  • New in 11.3 – Optional VOIP using Twilio® – Having a difficult time sourcing physical voice modems? Do your modems work poorly over lines meant for voice communication? Having trouble configuring reliable modem redundancy when using virtual machines? The VTScada Alarm Notification System now optionally supports voice telephony alarm notification functionality using Twilio**, a paid web-based communications platform. This requires SCADA access to the Internet and a Twilio account.
  • Running VTScada as a Service? – This feature introduced in version 11.1 allows VTScada to optionally run in the background without an active user interface. Please note that Microsoft does not permit Windows services to access SAPI, the built-in Windows text-to-speech engine. This means that if you’re using the VTScada Alarm Notification System and you have configured your application to run as a service, the outgoing alarm calls will be silent. In this case, we recommend using Twilio (above) for alarm annunciation.This is not an issue for standard VTScada installations.

Automatic SCADA Alarm Notification Failover

Server failover is an important factor in ensuring uptime and accessibility. This extends to alarm notification. Easily create lists of backup alarm notification servers that will automatically and seamlessly take over if the primary is unavailable. Responsibility will return to the primary server when it is restored.

Application-level Security

Secure access on incoming and outgoing calls is maintained through the use of the standard VTScada Security Manager. To receive status or alarm information, users are prompted by VTScada for their password. Users who do not have the ‘Alarm Acknowledge’ security privilege will not be able to acknowledge alarms.

Mobile Alarm Management

VTScada Thin Clients (licensed separately) allow you to securely view and acknowledge alarms anywhere using PCs, or HTML5 compliant smart phones and tablets. Thin Clients supersede the VTScada WAP Browser which was retired in 11.2.
