Add/Edit Address Mapping Dialog
This dialog is used to edit an entry or add a new entry in the Address Mapping.
The Station edit control displays the address of the remote DNP station. Valid values for this field
are from 0 to 65519.
The Object Type combo box displays the DNP data Object Type. The list of available types
includes: Binary Input, Binary Output, 16-bit Analog Input, 32-bit Analog Input, Short Floating
Point Analog Input, 16-bit Analog Output, 32-bit Analog Output, Short Floating Point Analog
Output, 16-bit Counter Input, 32-bit Counter Input. The Default selection is Binary Input.
The First Point edit control displays the starting address of the remote DNP data points. Valid
values are from 0 to 65519.
The Number edit control displays the number of remote points to be mapped. Valid values for this
field are from 1 to 9999.
The First Register edit control displays the starting address of local Modbus register where the
remote data points are to be mapped. Valid values depend on the selection of DNP Object Type and
are as follows:
For Binary Inputs valid range is from 10001 to 14096.
For Binary Outputs valid range is from 00001 to 04096.
For Analog Inputs and Counter Inputs valid range is from 30001 to 39999.
For Analog Outputs valid range is from 40001 to 49999.
The OK button checks the data for this table entry. If the data is valid the dialog is closed. If the
table data entered is invalid, an error message is displayed and the dialog remains open. The table
entry is invalid if any of the fields is out of range. The data is also invalid if it conflicts with another
entry in the table. Such conflict occurs when the combination of station number, object type, and
object address is not unique. The ordering of items in this table is not important.
The Cancel button closes the dialog without saving changes.
Routing
In a typical application the SCADAPack controller, configured for DNP, will act as a DNP slave
station in a network. The SCADA system will communicate directly with all the DNP slave stations
in the SCADA system.
DNP routing is a method for routing, or forwarding, of messages received from the SCADA system,
through the SCADAPack controller, to a remote DNP slave station. The SCADAPack DNP slave
station will respond to all messages sent to it from the SCADA system, as well as broadcast
