- By better utilizing your personnel - no need to keep someone in front of the central monitor all the time
- By saving on repair and clean-up costs
- By avoiding lost production or sales
- By ensuring regulatory and procedural compliance through complete alarm life-cycle audit
SMS and pagers have the following problems:
- Lack positive message acknowledgement/accountability
- Delivery success and time can be inconsistent
- Limited content (message size and unstructured text)
- Must acknowledge using a different device and/or application, thus hindering collaboration
- Must use another device or application to research the alarm. No easy way to interact with the SCADA system and no real-time query
- Does not use GPS to determine notification recipients
- Understanding the overall situation requires reviewing multiple messages to construct a mental model
Laptops have the following problems:
- Notification requires separate application if user is not logged in or watching the screen
- Potential delay due to disconnect between notification of an alarm and user's ability to respond to or research the alarm
- Push technology requires separate application
- Escalation procedures occur through separate escalation application
- Remote desktop applications need a device with footprint larger than a smart phone's that usually have higher power requirements than handheld devices
- Requires additional back-office licenses to provide connectivity and login
- Has minimal transparent reconnection capabilities in unreliable networks
- All data resides on the server. Viewing data requires a live connection to the server
- Significant data bandwidth requirements can lead to poor usability due to poor performance
- Does not use GPS (location awareness) to determine notification recipients
- Remote desktop requires a manual reconnect/re-login process that can be lengthy
- Browsers require you to be connected to the Web to see the SCADA data. With SCADA-Aware Mobile, you get historical and related data on the phone, and it stays on the phone even if you get disconnected. Unreliable network becomes less of an issue.
- Browsers can't use GPS to check your location. SCADA-Aware Mobile can.
An alarm goes off! John Smith, the on call field service engineer, gets the message, "Tank 2 at critical level"! "Why did that happen?" He wonders. "What's wrong? Now I have to drive all the way over there and it'll take me 30 minutes! I wonder if I need Jerry to fix the problem? What is the problem?"
SCADA-Aware Mobile helps solve his problems. When he gets the alarm notification, he can query related tag values as well as historical information right from his smartphone. Related tags indicate the skillset required to address the alarm. Historical data will provide a level of urgency depending on how quickly the threshold values are changing. With this additional information, the alarm can be acknowledged and informed next steps can be determined (including who else to contact, if needed). Other individuals who received the alarm notification will get an update of who has taken ownership of the event.
Sending a field service engineer on site is costly to the organization. SCADA-Aware Mobile helps minimize the number of trips to the site, improves on the accuracy of the skillsets needed to resolve the issue, and reduces the organization's overall cost. Reducing these risks also improves the safety for the impacted employees.How does the ownership visibility help?
When someone acknowledges the alarm, it's reported and recorded in the SCADA system. If the alarm was sent to other people, they will also see that acknowledgement, and will know who now "owns" the alarm.
How will SCADA-Aware Mobile help me with unreliable network connection?
- With SCADA-Aware Mobile, you get historical and related data on the phone, and it stays on the phone even if you get disconnected. Unreliable network becomes less of an issue
- If you get disconnected from the network when your mobile device should be available to receive alarms, SCADA-Aware Mobile sends out an alarm so that your peers and manager become aware of the situation. Also, your own device notifies you that you're not in a position to receive alarms
If the server cannot "push" the notification alarm to the right person's mobile device, then the device will "pull" it from the server. The mobile device checks with the server for alarms in defined time intervals. This technology is based on the patented capabilities of Voyager, our middleware software.
How does the GPS-based alarm delivery work?
For each possible tag group or user group, a geo-fence can be defined (for example, a 5-mile radius around the event location). When that alarm goes off, designated personnel within that geo-fence get the alarm. If none of them acknowledges the alarm, then, after a defined time-period, the alarm escalates and goes beyond the geo-fence. This ensures faster response and eliminates duplicate action. However, if the manager of the designated personnel (for that alarm) wants to see the alarm even if (s)he is outside the geo-fence, that can be configured into the system.
The GPS-based message delivery and peer visibility of alarm acknowledgment ensures that your personnel won't get distracted unnecessarily, and it will save on overtime and vehicle gasoline cost.
SMS, Pagers, laptops, and browsers don't use GPS (location awareness) to determine notification recipients.
What happens when the intended person does not respond to the alarm?
The alarm gets escalated. There are three levels of escalation following the initial alarm. At each level, previous recipients can also see the escalation and details.
What data can the alarm recipient view through his mobile device?
Users can query and access current SCADA data from their mobile device. A group of historical and up to 10 related SCADA data is delivered to the mobile device along with the alarm.
How are things actually automated through SCADA-Aware Mobile?
- When an alarm goes off, someone in the control room doesn't have to make any calls. In fact, no one has to man the control room all the time to check if there's any alarm, or anything that requires the generation of an alarm.
- When someone acknowledges the alarm, his peers and manager can see it automatically and thus know who "owns" the alarm now
- The system does automated monitoring of devices that should be available at a given time to receive alarms. If such a device that should be available is not, then, after a configured time, the system sends out an alarm, and the device also notifies the user
- If no one acknowledges the alarm, it automatically escalates to the next level. There are three levels of escalation after the initial alarm
Once logged-in, you can stay so indefinitely. Even if your device is turned off, you'll be considered logged-in. However, if your device is not available to receive alarm when it should be available (for example, it's turned off or you're outside the geo-fence or network), an automated alarm is sent out.What information is recorded following the alarm for audit purposes?
SCADA-Aware Mobile provides complete alarm life-cycle audit. The following are recorded in the database, and could be seen from both desktop editor and smartphone:
- Tag entering an alarm state
- Time the alarm was sent to a device
- Time when the alarm was received by the device
- Who acknowledged the alarm and when
- Time an alarm escalated
We utilize Microsoft's Windows Server Failover Clustering (WSFC) functionality. This provides local high availability through redundancy at the server-instance level—a failover cluster instance (FCI). An FCI is a single instance of SQL Server that is installed across Windows Server Failover Clustering (WSFC) nodes and, possibly, across multiple subnets. On the network, an FCI appears to be an instance of SQL Server running on a single computer, but the FCI provides failover from one WSFC node to another if the current node becomes unavailable.How is unreliable network coverage handled?
We review the coverage by different carriers in a given area. If we find significant coverage differences between carriers, we suggest remedial actions, such as power/carrier boosters for vehicles. Small pockets with no coverage is not a big issue for SCADA-Aware Mobile. Usually it only needs edge network capabilities to connect. Since the amount of data transmitted for SCADA-Aware Mobile is usually small, the connectivity window does not need to be long. It's different from e-mail/web browsing, which often does not work reliably and transmits much more data.How is the mobile device and user authenticated?
When the user launches the client, they are prompted for a username and password. This can be authenticated against an OpenLDAP / Active Directory server. The username and password can alternately be locally authenticated in the application and stored in the event server's database. If this method is chosen, the password is stored in encrypted form. Transmission of password information does not occur in clear text.
While the device id is transmitted, it is not used for authentication purposes. The device id is used to distinguish devices when the user is concurrently logged in.Will I have to change my existing SCADA system to implement SCADA-Aware Mobile?
No. Existing SCADA systems don't need to be changed.
Recursion will, however, need to update the SCADA database to incorporate our one-button acknowledgment.How is tag info transferred to the SCADA-Aware Mobile system?
Bulk import done during commissioning and startup.How does SCADA-Aware Mobile handle long tagnames?
By grouping or aliasing the tagnames.What smartphones does SCADA-Aware Mobile cover?
Blackberry, iPhone and AndroidWhat OS/platforms does SCADA-Aware Mobile run on?
For smartphones – Blackberry (OS5 and OS6), iPhone (iOS 5) and Android (OS2.2 or greater). For PCs, any PC with Windows XP SP3 or newer operating system.How do you sell SCADA-Aware Mobile?
