3.8 [DNP Master Commands]
The [DNP MASTER COMMANDS] section of the configuration file sets the DNP
master port command list. This list polls DNP slave devices attached to a
simulated master port. The module supports numerous commands. This permits
the module to interface with a wide variety of DNP protocol devices.
The command list is formatted differently than the other sections of the
configuration file. Commands are present in a block between the labels START
and END. These labels inform the program where the list resides. The module's
program will parse all commands after the START label until it reaches the END
label or maximum number of commands are processed.
The following table describes the structure of a single command.
[DNP Master Commands] This section header defines the location of
the DNP master command list.
START This string signals the start of the command
list.
# 1 2 3 4 5 6 7 8 9 10
#Flags/ Node Data Data Cmd Device Point DNP DB IED DB Poll
#Enable Address Object Variation Func Address Count Address Address Interval
6 2 1 0 1 0 -20 -1 0 0
END This string signals the end of the command
list.
Function codes used for each command are specific to the module and are
defined to permit the module to interface with a wide variety of DNP
communication devices.
