3.1 Configuration File

The MVI94-DNP module stores its configuration in a text file called Master.Cfg or Slave.Cfg, located in the module's flash memory. When the module starts up, it reads the configuration file and uses the information to control how the Distributed Network Protocol protocol interacts with the module's application port(s).

The configuration file is arranged in Sections, with a heading in [ ] characters at the beginning of each section. Each Section contains a list of Parameters and Values, followed by an optional Comment that explains the parameter.

The following illustration shows an example of a Section, a Parameter, a Value, and a Comment.

The Parameter must be followed by a [:] (colon) character. The text following the

[:] is a Value.

The module ignores "comment" text following the [#] character. Use comments to document your configuration settings.

You can get a sample configuration file for the module in the following places:  Copy the Master.Cfg or Slave.Cfg from the module's flash memory to your

Link level to obtain a confirmation. If this value is set to 0, retries are disabled at the data link level of the protocol. This parameter is only used if the frame is sent with confirmation requested.

Time-out period the master will wait for each response message fragment. If data link confirms are enabled, make sure the time-out period is set long enough to permit all data confirm retries.

This word contains bits that define the slave mode. The slave mode defines the functionality of the slave device and can be combined in any combination. The fields have the following definition: Enable: determines if this slave will be used. Unsol Msg: causes an enabled unsolicited response message to be sent to the slave when its RESTART IIN bit is set. This parameter is also required for unsolicited message reporting by the IED unit. Use DM: uses delay measurement. Auto Time Sync: time synchronization used when NEED TIME IIN bit set.

A record is required for each IED unit on the master port. As the program reads in the information, it generates a list of slaves as shown in the following example:

When the commands are read in from the configuration, a link between the IED point and the module's database is generated and stored in this link list. This data is used by the module to handle event data transferred from the IED units to the module. When the master port receives an event from an IED unit, the data in the link list places the received data into the module's database.

3.7.1 Command List

The command list stores the command list used by the DNP master port. This list only must be defined if the DNP master port is used. Up to 300 commands can be defined for the master port. The structure of each row in the list is shown in the following table.

Word Offset Definitions

0 Port/Flags 1 Slave Address 2 Object 3 Variation 4 Function 5 Address in Slave 6 Point Count 7 DNP DB Address 8 IED DB Address 9 Poll Interval

The definition of each parameter required for each command is provided in the following table.

Bits in the Port/Flags parameter are dependent on the data type. The following table defines the Port/Flags bits for binary input, analog input and counter data points.

Port/Flags Bits Description Decimal Equivalent

0 to 1 Communication port (0=Internal, 2=Port 2) 0 or 2 2 Enable/Disable Command (1=Enable, 0=Disable) 4 3 RBE Flag(0=Events from IED, 1=Events by module) 8 4 to 7 Not Used

For these data types the qualifier used in the data request depends on the Point Count and Address in Slave fields in the command as follows:

If Point Count < 0, then use Qualifier 06h (All points, packed & -Point Count = # of points to consider)

If Address in Slave = 0 & Point Count > 0, then use Qualifier 00h or 01h (points 0 to Point Count -1)

If Address in Slave > 0 & Point Count > 0, then use Qualifier 00h or 01h (Address in Slave to Address in Slave + Point Count -1)
