Configuring a WITS Analog Point

The ClearSCADA WITS driver supports Analog Input and Analog Output points. These analog points have a combination of configuration settings that are:

• Common to many types of point.
• Common to DNP3 points
• Specific to WITS analog points (i.e. available for both analog input and analog output points)
• Specific to WITS analog input points or WITS analog output points.

To configure a WITS analog point, you need to use the Analog Input Point Form or Analog Output Point Form as appropriate.

The Form contains many fields, organized into tabs. Some of these tabs are common to many types of database item, but the Analog Point contains settings that are specific to WITS.

For information on the settings on the various tabs, please refer to the following topics:

• Identification tab—see Defining Identification Details

• Location—Use to specify the item's geographical coordinates. (You need only configure the properties on this tab if your system uses ClearSCADA's Geographical Location features.)

• User Methods tab—see Using the User Methods Tab to Define Custom Actions
• Alarm tab—see Defining an Item or Group's Alarm Properties
• Redirection tab—see Configure Alarm Redirections for an Item or Group
• Historic tab—see Defining Historic Details for a Point.

• Analog Point tab—see:

  • Configure General Point Properties
  • Scanning States for WITS Database Points
  • Alarm Limits for WITS Analog Points
  • Profiles for WITS Database Points
  • Severity Types and Actions for WITS Database Points
  • Hysteresis for WITS Analog Points
  • DNP3 Object Flag Actions
  • Scaling for WITS Analog Points
  • Define the Appearance of an Analog Point's Values
  • Define whether an Analog Point can be Overridden
  • Define the Criteria for a Significant Change in Value.
  • Detect whether an Analog Point has Stopped Changing
  • Define an Analog Point's Trend Settings
  • Logged Data for WITS Database Points
  • Historic Data Filter for WITS Database Points
• Control tab—see:
  • Specify Whether an Output Point Is Controlled by ClearSCADA
  • Specify which Outstations are Integrity Polled After a Successful Control
  • Configure the Control Properties of a DNP3 Analog Output Point.
• Control Checks tab—Optionally use to configure the Control Checks settings (see Configuring Control Checks Settings).

When you have completed the point's configuration, you need to download the configuration to the Field Device by using the Outstation database item's Download Configuration (WITS Outstation) action.

If your Field Device does not support configuration download, you will need to make the same changes to the Field Device's configuration locally.
