The Simple OPC driver supports Analog Input and Analog Output points.
The points are used to map ‘point’ data on OPA servers into Geo SCADA Expert in a format that it can understand, and vice versa.
Configure the properties of each analog point using the fields on the Simple OPC Analog Point Form.
This section covers configuration of analog-specific properties on the OPC tab of the Form.
Use the fields on the OPC tab to:
- Configure General Properties on the OPC Tab
- Specify the Source Value of a Point
- Configure Point Scaling (see Scale Analog Values for use in Geo SCADA Expert in the Geo SCADA Expert Guide to Simple Drivers)
- Define Significant Change Properties (see Define the Criteria for a Significant Change in Value in the Geo SCADA Expert Guide to Core Point Configuration)
- Prevent Fleeting Changes in Value from Changing the Point State
- Define the Background Logging Properties
- Define the Historic Data Storage Properties
- Define which Configuration Properties are Retrieved from an OPC Source.
