Data sources

Types of data sources

There are two types of sources for loop data: historical sources and real-time sources.

  • Select the correct data source using the radio buttons, and the drop down menus.

  • Note that this is to read loop data, not the loop configuration information found in the loop definitions file.

  • Each Action Object configured can read data from only one data source.

  • Each Action Object configured can read data from a different data source.

 

Historical data sources

Real-time data sources

Typical data sources

  1. OPC Classic HDA client

  2. Proficy Historian

  3. Other historians

  1. OPC Classic DA Client,

  2. Optimized DB

 

Data collected

  1. Timestamp,

  2. Quality,

  3. Value for each tag in the loop

  1. Timestamp,

  2. Quality,

  3. Value for each tag in the loop

Supported Action Objects

  1. Scheduled Process+ Action Objects.

  2. Ad hoc Process+ Action Objects - they require immediate access to already present loop data.

  1. Scheduled Process+ Action Objects only.

Data collection period delay

No delay - historical data is already present in historians

Delay until end of scheduled period - such as end of shift or end of day

Troubleshooting data availability

If your Process+ KPIs have been generated and no data is present, check the following possibilities:

Problem

Possible causes

Solution

No data collected for scheduled Process+ KPIs.

The scheduled time for collecting data is not yet finished.

Confirm the data collection period scheduled:

No data collected in a real-time data source.

The Process+ KPIs were calculated over a period when the server was off.

Contact the systems administrator to ensure that the server is turned on, and deploy your Action Object again.

Data no longer stored.

The data has been deleted as the defined number of days for storing the interim data has passed.

The interim data is stored for 30 days and cannot be changed.

Data was collected, but no data shows on the graphs.

The data is bad quality.

Ensure that only good quality data records are used.
