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'.
ClearSCADA is a flexible and extensible SCADA host platform that can be used for a multitude of purposes, including gathering data from and controlling remote devices. The ClearSCADA Totalflow Driver extends the core functionality of ClearSCADA to enable it to communicate with supported ABB Totalflow flow computers using ABB’s custom DB2 Protocol.
The ClearSCADA Totalflow driver provides a subset of the features that are available using ABB’s custom DB2 Protocol, with a bias towards gathering historical data from Totalflow flow computers.
With the ClearSCADA Totalflow Driver, you can:
- Retrieve daily and log period history from a Totalflow. The driver will backfill missing historic data due to communications outages.
- Read analog and discrete points on a Totalflow.
- Write to (control) analog and discrete points on a Totalflow.
- Automatically keep the clock on a Totalflow synchronized with the host clock, if configured to do so.
- Retrieve event logs from a Totalflow and store them in a user friendly format in the ClearSCADA database.
- Retrieve alarm bits from a Totalflow and store them in the ClearSCADA database.
- Implement complex systems, like redundant ClearSCADA servers. The ClearSCADA Totalflow driver integrates natively into ClearSCADA.
- Read current values, like today’s volume for a gas flow meter run, from a Totalflow.
- Read and write strings, like a unit’s label, or a point tag, from a Totalflow.
- Make common changes, like changing the orifice plate diameter, or the gas composition for AGA-8 calculations, from within ClearSCADA.
ATTENTION: The level of technical information in this guide is written for users who have an advanced level of expertise with ClearSCADA, Microsoft Windows, electronic flow measurement and Totalflow flow computers.
