Specify the Map Size

Each populated row in a DNP3 SCADAPack 32-Bit Point Modbus Map represents a block of Modbus registers. One row is required for each contiguous block of 32-bit point data that the Modbus master is to read or write from a SCADAPack E outstation. By default each new DNP3 SCADAPack 32-bit Point Modbus Map has one row.

1. Display the Database Bar (see Display an Explorer Bar).
2. Right-click on the Map that you want to edit.
   A context sensitive menu is displayed.
3. Select the Edit <Name> Modbus Map option, where <Name> refers to the assigned map name.
   The map editor is displayed in the Document Window.
4. Right-click on the map editor.
   A context-sensitive menu is displayed.

   

5. Select the Modbus Map Size option.
   The Change SCADAPack 32-but Modbus Map Size window is displayed.

   

6. Enter the required map size in the New field. (The range is 1 to 254 inclusive.)
7. Select the OK button to confirm the change.
   The window is closed and the corresponding number of rows appear on the Map.
