 40001 through 49998
The Class of Event Object parameter specifies the event object class the 32-Bit Counter Input is
assigned. If Unsolicited reporting is not required for a DNP point, it is recommended to set its Class
0 or None. The selections are:
 None
 Class 1
 Class 2
 Class 3
The Threshold parameter specifies whether the RTU generates events. The value entered is the
minimum number of counts that the 32-Bit Counter Input must change since it was last reported.
Setting this value to zero disables generating events for the 32-Bit Counter Input point. Valid
threshold values are 0 to 4,294,967,295.
The Allow Duplicate Modbus Addresses checkbox determines if the Modbus I/O database
addresses assigned to the DNP data points must be unique. Check this box if you want to allow more
than one point to use the same Modbus address.
Click the OK button to accept the 32-Bit Counter Input parameters and close the DNP Settings
dialog.
Click the Cancel button to close the dialog without saving any changes.
Click the Add button to add the current 32-Bit Counter Input to the DNP configuration.
Click the Copy button to copy the current 32-Bit Counter Input parameters to the next DNP Address.
Click the Delete button to delete the current 32-Bit Counter Input.
Click the Move Up button to move the current 32-Bit Counter Input up one position in the tree
control branch.
Click the Move Down button to move the current 32-Bit Counter Input down one position in the
tree control branch.
DNP Diagnostics
DNP Diagnostics provide Master station and Outstation DNP diagnostics. The diagnostics provide
detailed information on the status of DNP communication and DNP data points. This information is
useful when debugging DNP station and network problems that may arise.
DNP diagnostics are available for local DNP information using the DNP Status command.
 For TelePACE applications select Controller >> DNP Status from the menu bar. See Chapter 0
for information on DNP Status diagnostics.
 For ISaGRAF applications select Tools >> Controller >> DNP Status from the program
window menu bar.
SCADAPack 32 controllers support DNP master operations. DNP diagnostics are available for
master stations using the DNP Master Status command.
