NOTE: In addition to the analog points mentioned below, ClearSCADA can support other types of analog point using an Advanced Modbus Extension Driver. For information on any Modbus points not listed below, see the relevant Advanced Modbus driver extension guide.
The Advanced Modbus driver supports Generic Modbus Analog Input points and Analog Output points.
Configure the properties for each analog point using the fields on the Generic Modbus Analog Input Point Form, or the Generic Modbus Analog Output Point Form, as appropriate.
This section covers configuration of properties on the Analog Point tab of each Form, and the properties on the Control tab of the Generic Modbus Analog Output Point Form. For information on the fields on other tabs, see Tabs on Point Forms in the ClearSCADA Guide to Advanced Drivers.
For Generic Modbus Analog Input or Analog Output points, use the Analog Point tab to:
- Configure the General Generic Modbus Analog Point Properties
- Configure Alarm Limits
- Configure any Alarm Limit Profiles (see Specify any Alarm Limit Profiles in the ClearSCADA Guide to Core Point Configuration)
- Define the Point Scaling
- Define the Point Formatting (see Define the Appearance of an Analog Point’s Values in the ClearSCADA Guide to Core Point Configuration)
- Specify the Override Properties (see Define whether an Analog Point can be Overridden in the ClearSCADA Guide to Core Point Configuration)
- Specify the Significant Change Properties
- Configure the No Change Properties (see Detect whether an Analog Point has Stopped Changing in the ClearSCADA Guide to Core Point Configuration).
- Specify the Trend Properties (see Define an Analog Point’s Trend Settings in the ClearSCADA Guide to Core Point Configuration).
For Generic Modbus Analog Output points, use the Control tab to:
- Configure the Control Properties (see Define the Control Settings for an Analog Output Point in the ClearSCADA Guide to Core Point Configuration)
- Specify whether any Controllers are given Scanning Priority whenever a Control Action is Issued (see Promoting Scanning of Outstations Associated with Controls in the ClearSCADA Guide to Core Point Configuration).
