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