1.1 General

With the EN100 module firmware DNP3 IP from version V1.00, the Ethernet-based DNP3 IP protocol is imple­mented in addition to other transmission protocols (e.g. IEC 61850 and GOOSE, see chapter 1.7) in the
100 Mbit Ethernet module EN100.

The required settings are made using the DIGSI 4 parameterization software from version 4.85.

Detailed information on the EN100 module and the IEC 61850 engineering is given in the manuals:

• German edition: Handbuch Ethernetmodul EN100, Bestellnr. C53000-G1100-C167-x

• US-english edition: Manual Ethernet Module EN100, order no. C53000-G1140-C167-x

Abbreviations are used in the following text:

• for 100-MBit Ethernet module EN100: EN100

• for DNP3 IP over the internet protocol suite: DNP3 IP

Application

Figure 1-1 shows an application example of the SIPROTEC devices with DNP3 IP and GOOSE in an installa­tion where DNP3 IP is used for communication to a substation controller and GOOSE for inter-device data ex­change.

Fig. 1-1 Application Communication

NOTE

Refer to your device manual to find out whether the device you are using supports the DNP3 IP protocol.

NOTE

For the configuration of DNP3 IP a DIGSI 4 packet is required with IEC 61850 station configurator.

NOTE

The settings above are valid for all TCP connections in the same way; they are not configurable individually per
TCP connection or connected DNP3 IP master.

During startup of the Ethernet module it is checked whether all DNP3 IP parameters are configured in their valid
ranges given in table 1-4 and table 1-3. If a parameter value is detected outside the valid range, an error log
entry is issued on the EN100 module and the parameter is set to its default value (see figure 5-1).

1.5 DNP3 IP Networking Parameters

For the IP networking services, the following configuration parameters are available in the SIPROTEC device
(i.e. in the DNP3 IP mapping file, see chapter 2):

Table 1-4 DNP3 IP Networking Parameters

Parameter Description Range Default

Setting

TcpPortNumber1
TcpPortNumber2

The TCP ports to listen on.
Port numbers must be different.
If both port numbers are equal, only one
DNP3 IPserver is started, i.e. only one TCP connec­tion is available.

10000 to 65535 20000

List of IP addresses to accept TCP connections from.

All entries = *.*.*.*:
accept connection from any TCP client.

At least one entry is not = *.*.*.* and
one or more entries = *.*.*.*:
entries with *.*.*.* are ignored.

ApplKeepAliveTimeout Reload value for the keep-alive timer to monitor the

status of an active TCP connection on DNP3 IP appli­cation layer level. The keep-alive timer is restarted
whenever a message is received from the master.
If the timer times out, the device (DNP3 IP outstation)
transmits a Data Link Layer status request which
must be responded by the master or the connection
is assumed to have broken down and will be closed.

0 = timer is disabled

0.1 s to 3600.0 s in
100 ms steps

20.0 s

EnableDnpTimeSynch Determines whether the device (DNP3 IP outstation)

expects and evaluates time synchronization from
DNP3 IP master (see chapter 4.2).

0 = device does not
expect time synchroni­zation from DNP3 IP
master

1 = device expects time
synchronization from
DNP3 IP master

0 (dis­abled)

DnpTimeSynchMaster Determines in case of two connected DNP3 IP clients

which one acts as time master for the time synchroni­zation via DNP3 IP.

If only one client is connected, then this one also is
time master.

0 = the client which was
connected first

1 = client connected to
DNP3 IP server 1 (with
TcpPortNumber1)

2 = client connected to
DNP3 IP server 2 (with
TcpPortNumber2)

DnpTimeSynchAsUTC Acc. to "Time Synchronization" in DNP3 IP Spec. Vol.

5, the time for DNP3 IP time synchronization shall
(since Jan. 1st, 2008) correspond to Universal Coor­dinated Time, UTC.

This setting is used to support DNP3 IP clients which
send time synchronization in local time but should
normally remain unchanged to default value.

0 = DNP3 IP time syn­chronization with local
time

1 = DNP3 IP time syn­chronization with UTC

C53000-L2040-C354-1, Edition 02.2012

1.6 Buffered Events

Maximum number of buffered events (these values are fixed):

Table 1-5 Buffered Events

Event Numbers Note

Binary Input change:
DNP3 IP Object 2

100
as sequence of events

All changes will be entered in the event list, also multiple
events from the same data object. In case of overflow,
the internal indication IIN2.3 bit
EVENT_BUFFER_OVERFLOW is set and the oldest
event is lost. This internal indication remains set and is
reported to the DNP3 IP master until there is again
storage in the event buffer for at least one event.

Counter change:
DNP3 IP Object 22

10
most recent events

If a data object changes multiple times without the previ­ous event being sent, then a new event will overwrite the
value already stored in the event list.

Analog Input change:
DNP3 IP Object 32

50
most recent events

NOTE

Note that the Analog Input change includes measured values, DIGSI 4 data type MV, min/max values, DIGSI 4
data type MVT (Measured Value with Time), both as 16-bit Analog Change Events and statistic values, DIGSI 4
data type VI (Value Indication), as 32-Bit Analog Change Events.

1.7 File Transfer/Reading of Fault Records

19SIPROTEC, Communication Module, Communication Profile

C53000-L2040-C354-1, Edition 02.2012

1.7 File Transfer/Reading of Fault Records

Fault records from the device can be read using the file transfer feature of DNP3 IP (DNP3 IP object number
70 (file identifier), see table 1-2). The fault records are converted on the EN100 module to Comtrade format.

For reading a fault record, the following steps must be executed:

✧ Open the directory file of available fault records which are available using DNP3 IP object 70, variation 3

(open file), e.g.:

✧ The DNP3 IP outstation responds with DNP3 IP object 70, variation 4 (response).

✧ If no fault records are available, the returned file size is zero, otherwise it is different from zero, e.g.:

With this response, a file handle is returned → File(0x44495220).

✧ If the file size returned in the previous response is different from zero, read the directory file using DNP3 IP

object 70, var. 5 (read file). If a file size of zero was returned, then immediately close the file.

File read:

NOTE

The DNP3 IP Protocol Test Harness software from Triangle Microworks was used as DNP3 IP test master for
the examples.

NOTE

The file name must be “.” or “\” in order to open the directory.

And interpret the response as file information (a read of a directory returns file directory information data):

Close the file using DNP3 IP object 70, var. 4 (close file), e.g.:

Which is confirmed with:

✧ In the DNP3 IP master the file selection after directory read could look like this:

NOTE

It can be seen here that for each fault record two files are available, a *.cfg and a *.dat, as it is usual for
Comtrade.
