Real-Time Dashboards & Alerts

Smartphones | Tablets | Web Browsers | PC & Mac | More

Visual KPI reads multiple data sources in real-time (big data, historians, databases, manual data, web services and more) and adds context with KPIs, groups/hierarchy, alerts, and geolocation. It gets your critical data in the hands of more users without extensive training and it can be deployed in days, not months. Want to see how we do it?

What is it?

Visual KPI is mobile dashboard software for any device. It reads existing data sources and delivers KPIs, scorecards, analytics and alerts in real-time.

Who uses it?

Decision makers. Operations. Remote workers. Data Junkies. Anyone who values knowing what's happening right now, regardless of their device.

Why use it?

Mobility is no longer optional. Visual KPI presents problems and opportunities before it's too late. Oh, and there's no six-month project that "might" pay off.

Product FAQ > Data Sources > How can I use a Visual KPI function for a tag or expression if the data type changes dynamically?

Search the FAQ for entries containing:

When retrieving a value from a historian or database, the data source will sometimes return different data types based on the state of the system at that moment. For example, a tag value or expression normally returns a real number, but if an interface fails it might return “I/O Timeout” or some other text or enumerated value.

This causes the equation processor in Visual KPI to scratch its head. When a value changes type dynamically (from real to string for example) we had no real workaround for testing a value and then using the same value in an equation. Our equation processing engine wanted one or the other in any given expression. So we are introducing 4 new functions which will tolerate an expression of changing type:

IsEqualTo([expression],value
IsBetween([expression],low, high)
IsGreaterThan([expression],value)
IsLessThan([expression],value)

These functions can be used in any Visual KPI Attribute where equations are allowed. Here’s an example from the real world: In the “InService” Attribute for a KPI: 

<IsGreaterThan([instrument-tag-123],1.5)>

This will return “True” if the tag value is greater than 1.5, and will return “False” if the value is less than or equal to 1.5 OR returns a non-numeric value such as “I/O Timeout.”

Here's an example:

Old EquationValue of tagResult
<IF([tag]>1.5, True, False)> 50.0 True
  1.0 False
  "I/O Timeout" Equation not processed; error message shown
New EquationValue of tagResult
 <IsGreaterThan([tag],1.5)> 50.0 True
  1.0 False
  "I/O Timeout" False
