Adding 32-Bit Analog Inputs

32-Bit Analog Inputs are added to the DNP configuration using the 16-Bit Analog Input property

page. To add a 32-Bit Analog Input:

 Select 32-Bit Analog Inputs in the tree control section of the DNP Settings window.

 Click the Add button in the 32-Bit Analog Inputs property page.

 The 32-Bit Analog Input property page is now displayed.

 Edit the 32-Bit Analog Input parameters as required and then click the Add button.

As 32-Bit Analog Inputs are defined they are added as leaves to the 32-Bit Analog Inputs branch of

the tree control. When 32-Bit Analog Inputs are defined the 32-Bit Analog Inputs branch will display

a collapse / expand control to the left of the branch. Click this control to display all defined 32-Bit

Analog Inputs.

The 32-Bit Analog Input parameters are described in the following paragraphs.

The DNP Address window displays the DNP 32-Bit Analog Input address of the point. Each 32-Bit

Analog Input is assigned a DNP address as they are defined. The DNP point address starts at the

value set in the 32-bit Analog Input configuration dialog and increments by one with each defined

32-Bit Analog Input.

The Modbus Address parameter specifies the Modbus addresses of the 32-Bit Analog Input

assigned to the DNP Address. 32-Bit Analog Inputs use two consecutive Modbus registers for each

assigned DNP Address, the address that is entered in this box and the next consecutive Modbus

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:

 30001 through 39998
