NOTE:This section provides information about ‘Generic’ digital points. If your system is running an Advanced Modbus Extension Driver, other types of Advanced Modbus digital point might be available. For information about non-generic Advanced Modbus digital points, see the relevant Advanced Modbus extension driver guide.
The Advanced Modbus driver supports 1-, 2-, and 3-bit Digital Input points and Digital Output points.
Configure the properties for each Digital point using the fields on the Generic Modbus Digital Input Point Form, or the Generic Modbus Digital Output Point Form, as appropriate.
This section covers configuration of properties on the Digital Point tab of both Generic Modbus Digital Point Forms, and the properties on the Control tab for Digital Output points. The properties on other tabs are common to points on many advance drivers (see Tabs on Point Forms in the ClearSCADA Guide to Advanced Drivers).
Use the Digital Point tab to:
- Configure Common Point Properties
- Point State Properties
- Define Override Properties (see Define whether a Digital Point can be Overridden in the ClearSCADA Guide to Core Point Configuration)
- Define Trend Properties (see Define a Digital Point’s Trend Settings in the ClearSCADA Guide to Core Point Configuration).
For Generic Modbus Digital Output Points, use the Control tab to:
- Configure the Control Actions (see Define the Control Settings for a Digital 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)
- Specify the Type of Control Operation
- Specify Whether to Update the Point Value Immediately Following a Control.
