Introduction to the Lufkin SAMS 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:

Intended Audience

This guide is primarily intended for engineers who are responsible for configuring Lufkin SAMS items and features in the Geo SCADA Expert database.

The guide also contains information for operators and engineers who use the Lufkin SAMS driver to monitor rod pump activity.

Document Scope

This guide explains the configuration, features and database items that are specific to Geo SCADA Expert’s Lufkin SAMS driver. The driver is an Advanced Modbus extension driver. The driver provides additional functionality to enable Geo SCADA Expert to interface with Lufkin SAM rod pump controllers. The driver enables Geo SCADA Expert to communicate with the controllers using the Modbus protocol with proprietary extensions. Using the driver, Geo SCADA Expert can retrieve and process rod pump stroke and other data associated with monitoring the effectiveness of the rod pumps that are being used to lift liquid out of wells. The uploaded dynacard data can then be displayed as a series of Dynagraphs that users can analyze to determine the effectiveness of the pumps in the well fields.

In order to communicate with Lufkin SAM controllers, Geo SCADA Expert needs to run both the Advanced Modbus driver and the Lufkin SAMS extension driver (see Confirm that the Lufkin SAMS Server Component is Installed).

Use this Geo SCADA Expert Guide to the Lufkin SAMS Driver alongside the Geo SCADA Expert Guide to the Advanced Modbus Driver. As much of the information in the latter guide is assumed knowledge, we recommend that you read the Geo SCADA Expert Guide to the Advanced Modbus Driver before reading this driver guide.

The Lufkin SAMS driver documentation explains how to:

It also explains features that are of interest to operators, such as:
