This driver is a simple driver. It provides additional functionality to enable ClearSCADA to interface with specific supported devices using a particular protocol. To interact successfully with such devices, you need to:
- Install and run the driver
- Ensure that the driver is licensed
- Configure the required database items and settings on the driver
- Ensure that the database items (and any database items on which they depend) have valid, saved, configuration and are 'In Service'.
SDI-12 is an open protocol that can be used for communicating with micro-processor based sensors.
The ClearSCADA SDI-12 driver enables ClearSCADA to become an SDI-12 data recorder and read data from intelligent sensors, using the SDI-12 protocol. The ClearSCADA SDI-12 driver communicates with the sensors using serial communications.
This guide explains how to configure SDI-12 specific features and items within the ClearSCADA database (see Configuring SDI-12 Devices in ClearSCADA).
It also explains driver-specific aspects that may be of interest to System Administrators and engineers when investigating any unexpected system behavior (see SDI-12 Specific Status Display Attributes).
For SDI-12 information not covered by this guide, see the documentation supplied with your SDI-12 sensors, or see the SDI-12 website, www.sdi-12.org.
NOTE: There are no driver-specific pick actions for database items on this particular driver. However, users with the required privileges can add custom pick actions to a database item by using the User Methods tab on the relevant configuration Form (see Using the User Methods Tab to Define Custom Actions in the ClearSCADA Guide to Core Configuration). See a system administrator for the documentation associated with such custom actions (also known as ‘methods’).
