Override a plugin to add or disable support for additional tables

AVEVA Enterprise SCADA allows you to override or augment settings for existing plugins within the High Performance Data Export Framework (HPDEF).

To modify the existing plugin

Follow the procedure to add or modify configuration for an existing data export plugin.

1. In the %DNADataRoot%\RealTime\config\Settings directory, either create or open the RealTime_DataExport.json file.
2. Under the "Collect" plugin, add a new entry for the rate table to the "Tables" section and disable the plugin for the multistate table, as shown in the following code example:

{
  "RealTime": {
    "DataExport": {
      "Plugins": {
         "Collect": {
          "Tables": {
            "rate": {
              "Enabled": true,
              "Class": "OASySDNA.RealTime.DataExport.CustomCollect.RateHandler",
              "Assembly": "OASySDNA.RealTime.DataExport.CustomCollect"
             },
            "multistate": {
              "Enabled": false
            }
          }
        }
      }
     }
  }
}

3. Copy the OASySDNA.RealTime.DataExport.CustomCollect.dll file to the %DNADataRoot%\RealTime\bin directory.
4. Restart the RealTime service.
