Introduction to the WITS Driver

This driver is an extension driver. It provides additional application-specific functionality to the 'parent' driver with which it is associated. To interact successfully with devices using an extension driver, you need to:

Document Scope

This guide explains the configuration, features and database items that are specific to Geo SCADA Expert’s WITS driver. The driver is a DNP3 extension driver that provides the additional functionality required for Geo SCADA Expert to communicate with WITS Field Devices. The driver enables Geo SCADA Expert to communicate with devices using the WITS-DNP3 protocol (one of the Worldwide Industrial Telemetry Standards). The standard builds on the DNP3 protocol to satisfy specific functional requirements of the utilities industries.

Geo SCADA Expert (formerly ClearSCADA) versions 71 and above are WITS verified for WITS version 1.1. Geo SCADA Expert also supports WITS versions 1.0, 1.2, 1.3, and 3.0, but is not WITS verified for these versions. They use the DNP3 driver and the WITS DNP3 extension driver to communicate with WITS Field Devices. For this reason, you should make sure that both the DNP3 driver and the WITS driver are installed on all Geo SCADA Expert servers in your system before you create WITS items in your database (see Confirm that the DNP3 and WITS Server Components are Installed).

Only install the WITS Driver if you have a WITS driver license (the WITS driver cannot be used in Geo SCADA Expert's demo mode). Installing the WITS Driver without an appropriate license will result in your Geo SCADA Expert server being unable to run.

Do not install the WITS Driver for the demo version of Geo SCADA Expert.

This Geo SCADA Expert Guide to the WITS Driver explains how to configure WITS-specific features and items within the Geo SCADA Expert database. For more information, see the topics that are listed in the gray footer section at the bottom of this topic. Select the relevant entry to display the topic that you require.

As the WITS driver is an extension of the DNP3 driver, WITS database items have many configuration settings that work in exactly the same way as DNP3. They also have settings that are common to many different types of database item (such as Identification settings). In this WITS Driver Guide, we explain how to use the WITS-specific configuration settings. For any 'common' settings, we will refer you to other Geo SCADA Expert Guides.

We also recommend that you read the Geo SCADA Expert Guide to the DNP3 Driver before reading the WITS driver guide. Much of the information covered is assumed knowledge and needs to be followed in conjunction with information in this driver guide. It is also advisable that you have access to your WITS Field Device product documentation when reading this guide.
