Adding Short Floating Point Analog Inputs
Short Floating Point Analog Inputs are added to the DNP configuration using the 16-Bit Analog
Input property page. To add a Short Floating Point Analog Input:
Select Short Floating Point Analog Input in the tree control section of the DNP Settings
window.
Click the Add button in the Short Floating Point Analog Inputs property page.
The Short Floating Point Analog Input property page is now displayed.
Edit the Short Floating Point Analog Input parameters as required and then click the Add button.
As Short Floating Point Analog Inputs are defined they are added as leaves to the Short Floating
Point Analog Inputs branch of the tree control. When Short Floating Point Analog Inputs are defined
the Short Floating Point Analog Inputs branch will display a collapse / expand control to the left of
the branch. Click this control to display all defined Short Floating Point Analog Inputs.
The Short Floating Point Analog Input parameters are described in the following paragraphs.
The DNP Address window displays the DNP Short Floating Point Analog Input address of the
point. Each Short Floating Point Analog Input is assigned a DNP address as they are defined. The
DNP point address starts at the value set in the Short Floating Point Analog Input configuration
dialog and increments by one with each defined Short Floating Point Analog Input.
The Modbus Address parameter specifies the Modbus addresses of the Short Floating Point Analog
Input assigned to the DNP Address. Short Floating Point 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 register. The SCADAPack and Micro16 controllers use Modbus addressing for
all analog 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:
