DNP Master Port Command List
The DNP master port supports the use of a command list. This list issues DNP
data requests and commands to DNP slave devices. Commands define the data
types and points to be used in the command and the database locations in the
module. The DNP and/or IED databases can be used with the commands. For
example, the master port could request binary input data from a slave device and
place the response data in the DNP or IED database. Another request could
place the response binary data of another slave in both the DNP and IED
databases. Use the configuration file (DNP.CFG) to configure the command list.
