With ClearSCADA’s Lufkin SAMS driver, you use:
- Generic Advanced Modbus points to retrieve current point data from a Lufkin SAMS controller. ClearSCADA retrieves the data at the ‘Retrieval Interval’ specified on the Point Form (see Configure Common Point Properties in the ClearSCADA Guide to the Advanced Modbus Driver).
For information on Generic Advanced Modbus points, see Points Used on Generic Modbus Controllers in the ClearSCADA Guide to the Advanced Modbus Driver.
- Lufkin SAMS points to retrieve historic (time stamped) data that is stored on a Lufkin SAMS controller. (Lufkin SAMS points are designed to process only historic data.) ClearSCADA retrieves the historic point data at the 'Historic Data Poll Interval' specified on the Lufkin SAMS outstation Form (see Define the Historic Data Poll Interval).
Lufkin SAMS controllers support a combination of these Lufkin SAMS point types:
- Lufkin SAMS Analog Input Points—see Configuring Lufkin SAMS Analog Input Points.
- Lufkin SAMS Digital Input Points—see Configuring Lufkin SAMS Digital Input Points.
For information on the minimal amount of configuration that you can undertake to produce a functional Lufkin SAMS point in ClearSCADA, see Minimum Configuration.
