Adding 32-Bit Analog Outputs
32-Bit Analog Outputs are added to the DNP configuration using the 32-Bit Analog Outputs
property page. To add a 32-Bit Analog Output:
 Select 32-Bit Analog Outputs in the tree control section of the DNP Settings window.
 Click the Add button in the 16-Bit Analog Outputs property page.
 The 32-Bit Analog Output property page is now displayed.
 Edit the 32-Bit Analog Outputs parameters as required and then click the Add button.
As 32-Bit Analog Outputs are defined they are added as leaves to the Binary Inputs branch of the
tree control. When 32-Bit Analog Outputs are defined the 32-Bit Analog Outputs branch will display
a collapse / expand control to the left of the branch. Click this control to display all defined 32-Bit
Analog Outputs.
The 32-Bit Analog Outputs parameters are described in the following paragraphs.
The DNP Address window displays the DNP 32-Bit Analog Output address of the point. Each 16-
Bit Analog Output is assigned a DNP address s they are defined. The DNP point address starts at the
value set in the 32-bit Analog Output configuration dialog and increments by one with each defined
32-Bit Analog Output.
The Modbus Address parameter specifies the Modbus address of the 32-Bit Analog Output assigned
to the DNP Address. 32-Bit Analog Outputs use two consecutive Modbus registers for each assigned
DNP Address, the address that is entered in this box and the next consecutive Modbus register. The
SCADAPack and Micro16 controllers use Modbus addressing for all analog outputs. Refer to the I/O
Database Registers section of the TelePACE Ladder Logic Reference and User Manual for
complete information on analog output addressing in the SCADAPack and Micro16 controllers.
Valid Modbus addresses are:
