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 ROC Plus Driver extends the core functionality of ClearSCADA to enable it to communicate with Emerson Remote Operations Controller (ROC) devices, using the ROC Plus Protocol. The driver enables ClearSCADA to communicate with supported Emerson ROC devices, including ROC809 and ROC827 devices.
The ClearSCADA ROC Plus driver provides a subset of the features that are available using Emerson’s custom ROC Plus Protocol, with a bias towards gathering historical data from ROC flow computers.
With the ClearSCADA ROC Plus driver, you can:
- Retrieve daily, hourly and minute history from a ROC. The driver will backfill missing historic data due to communications outages.
- Read analog and discrete points on a ROC.
- Write to (control) analog and discrete points on a ROC.
- Automatically keep the clock on a ROC synchronized with the host clock, if configured to do so.
- Retrieve event logs from a ROC and store them in a user friendly format in the ClearSCADA database.
- Retrieve alarm logs from a ROC and store them in a user friendly format in the ClearSCADA database.
- Implement complex systems, like redundant ClearSCADA servers. The ClearSCADA ROC Plus driver integrates natively into ClearSCADA.
- Read current values, like today’s volume for a gas flow meter run, from a ROC.
- Read and write strings, like a unit’s label, or a point tag, from a ROC.
- Make common changes, like changing the orifice plate diameter, or the gas composition for AGA-8 calculations, from within ClearSCADA.
- Read and control user defined points in a ROC.
ATTENTION: The level of technical information in this guide is for users who have an advanced level of expertise with ClearSCADA, Microsoft Windows, electronic flow measurement and ROC devices.
