2.1.1 [SNTP CLIENT]

The [SNTP CLIENT] section of the configuration (.CFG) file or of the PCB
configuration is used to specify the parameters for the Simple Network Time
Protocol (SNTP) Client provided with the protocol driver. The Client is required in
order to keep the driver's internal clock set correctly. This version of the driver
supports SNTP Revision 3 and stratum between 1 and 14.

The updated time and date information is used when sending clock
synchronization commands to remote IEC-60870-5-104 servers.

SNTP is used for time synchronization of produced and consumed commands.
When an exchange occurs, the driver compares time stamps from the previous
exchange. When the new exchange time is less than the previous exchange, the
exchange is ignored. This can occur when the Ethernet packets are routed and
delayed. Time synchronization provides for data integrity.

Configuring the Gateway 104C Version 3 ♦ ProLinx Gateway
Protocol Manual IEC 60870-5-104 Client (Firmware v3.xx)

As Seen in PCB

The SNTP driver will compute a new clock value every 5 minutes using the
average value of 10 samples each collected over an approximate 6-second
period. This new value will be used to adjust the clock maintained by the SNTP
driver and used by the application. If a valid database register is specified, the
driver will place the time value into the module's database. The first two registers
will contain the number of seconds and the next two registers will contain the
number of microseconds since January 1, 1970.

A list of some of the common SNTP servers can be obtained at
http://www.ntp.org/

or, http://support.ntp.org/bin/view/Servers/WebHome
Other server lists can be found by searching the World Wide Web for SNTP

Servers.

SNTP Server IP Address

Enter in dotted notation
This parameter sets the IP address of the SNTP server to utilize for time

acquisition. Select an SNTP server with the greatest accuracy that can be
accessed all the time from your network. Setting this IP address to 0.0.0.0
disables SNTP server requests.

Time Zone

-11 to 11
This parameter specifies the time zone offset to be used from the UTC time

zone. A value of zero uses UTC time. If the value entered is positive, the time
zone is west of the UTC time zone (for example, Eastern Standard Time is 5). If
the value entered is negative, the time zone is east of the UTC time zone (for
example, Continental Europe is -1).

Use Daylight Savings Time

YES or NO

This parameter specifies if daylight savings time will be used in the time
computation.

Database Register

-1 or 0 to 3996 as an even value
This parameter specifies if the NTP time computed by the driver is to be placed

into the module’s database. If a value of -1 is specified, the time will not be
placed into the database. If the value is between 0 and 3992, the time will be
placed in the database. The first 4 bytes will represent the seconds since
1/1/1970, and the second 4 bytes will represent the number of microseconds. An
even value should be used for the register value in order for the data to be stored
correctly.

t0 Connection Timeout

1 to 30, default value = 30

This is a timeout value, in seconds, to determine if a connection has been lost
with the remote server. If no traffic from the remote server is received for the
period of time specified by this parameter, the currently open IP socket
connection will be closed. The connection can be re-established by the Client by
opening a new connection.

t1 Timeout Set Value

1 to 255 DEFAULT VALUE = 15
This is the timeout of send or test ASDUs and is in units of seconds. After a

packet is sent from the unit, the server must acknowledge the packet within this
time interval or else the unit will close the connection.

t2 Timeout Set Value

1 to 255 DEFAULT VALUE = 10
This is a timeout of when to send an S-format message to the host to

acknowledge outstanding messages received. This parameter is in units of
seconds and must be less than the value set for t1.

2.1.4 [IEC-60870-5-104 Client x Sector x] Parameters

Common ASDU Address
At the application level, the gateway is identified by the Common ASDU

(Application Service Data Unit) Address. This address must match the CASDU

sent at the server unit. An ASDU is a data unit that transfers information objects
between the Client and the server.

If the gateway sends a message to a different Common ASDU, the server should
ignore the command.

Online Time Sync

Yes or No
This parameter specifies if the sector in the server device will be sent a time

synchronization command when the server device is first recognized as being
online. This should only be used for devices that do not send an EOI message
after initializing.

Online General Int

Yes or No
This parameter specifies if the sector in the server will be sent a general

interrogation command when the unit is first recognized as being online.

2.1.5 [IEC-60870-5-104 Client x Sector y]

This section allows the user to associate the monitored data points to module
database. These points are sent from the remote server to the module. There
are 3 parameters for each point association that you create: Data Type, Point
Index, Database Address.
The data type must be selected among one of the following supported types. The
Point Index is the Information Object Address which identifies the point in the
network. The Database Address defines the gateway database location on
where the point value will be stored. The database address could be defined as
bit-addressing, byte addressing, word addressing or double-word addressing
depending on the data type.

For additional information on how to set these parameters, see the Reference
chapter of this manual. The following ASDU data types are supported:

Monitor Single Point [M_SP_NA]

This section defines the Monitor Single-Point information object database.
Each information object (point) indicates one of two states, 1 = Bit On, 0 = Bit Off.
Each information object is one bit and the DB Address value corresponds to the

bit offset in the gateway memory database.
For additional information on how to set these parameters, see the Reference

chapter of this manual.

Monitor Double Point [M_DP_NA]

Each information object in the database can have one of four possible states, 00
= Intermediate, 01 = Off, 10 = On, and 11 = Intermediate.

Each information object is two bits and the DB Address value corresponds to the
bit offset in the gateway memory database.

Monitor Step Position [M_ST_NA]

Each information object is one 8-bit byte and the DB Address value corresponds
to the byte offset in the gateway memory database.

[M_BO_NA_1 104]

Each information object is four 8-bit bytes (two 16-bit words) and the DB Address

Each row of this section allows the configuration of one command to be sent to
the remote server. The command can be either a control point (single point,
double-point, etc..) or a general command such as clock synchronization to a
specific client.

The following parameters must be configured for each command:

Database Address

The interpretation for the database address parameter will depend on the
selected data type. The database address value is only significant to the control
data types (single point, double-point, etc…).

Examples:

If you select single point command type the database address is interpreted as a
bit-address. For example, a value of 32 means bit 0 of database word 2.

If you select regulating step point command type the database address is
interpreted as a byte-address. For example, a value of 32 means byte 0 of
database word 16.
If you select measured scaled integer command type the database address is
interpreted as a word-address. For example, a value of 32 means database word
32

If you select measured scaled integer command type the database address is
interpreted as a double-word-address. For example, a value of 32 means
database word 16, For the other command types (clock synchronization, read
command, reset process command and test command) you can use the
database address to trigger the command upon data change. However the value
itself is not used within the command.

2.2 Using the CommonNet Data Map

The Data Map section allows you to copy data between areas in the gateway's
internal database.

You can copy a maximum of 100 registers per Data Map command, and you can
configure a maximum of 200 separate copy commands.

You can copy data from the error or status tables in upper memory to internal
database registers in the User Data memory area.

You can rearrange the byte and/or word order during the copy process. For
example, by rearranging byte or word order, you can convert floating-point values
to the correct format for a different protocol.

You can also use the Data Map to condense widely dispersed data into one
contiguous data block, making it easier to access.

Protocol Manual IEC 60870-5-104 Client (Firmware v3.xx)

2.2.5 Delay Preset

This parameter sets an interval for each Data Map copy operation. The value you
put for the Delay Preset is not a fixed amount of time. It is the number of firmware
scans that must transpire between copy operations.

The firmware scan cycle can take a variable amount of time, depending on the
level of activity of the protocol drivers running on the ProLinx gateway and the
level of activity on the gateway's communication ports. Each firmware scan can
take from 1 to several milliseconds to complete. Therefore, Data Map copy
operations cannot be expected to happen at regular intervals.

If multiple copy operations (several rows in the Data map section) happen too
frequently or all happen in the same update interval, they could delay the process
scan of the gateway protocols, which could result in slow data updates or missed
data on communication ports. To avoid these potential problems, you should set
the Delay Preset to different values for each row in the Data Map section and set
them to higher, rather than lower, numbers.

For example, Delay Preset values below 1000 could begin to cause a noticeable
delay in data updates through the communication ports. And you should not set
all Delay Presets to the same value. Instead, use different values for each row in
the Data Map such as 1000, 1001, and 1002 or any other different Delay Preset
values you like. This will prevent the copies from happening concurrently and
prevent possible process scan delays.

The intent of this section is to provide a quick understanding of how the 104
gateway implements the IEC-60870-5-104 protocol, without going into complex
details of the specification.

The IEC-60870-5-104 protocol applies to telecontrol equipment and data
transmission systems for monitoring and controlling geographically widespread
processes. This protocol is similar to the IEC-60870-5-101 protocol, with the
addition of TCP/IP as the transport mechanism.

Any application with the IEC-60870-5-104 protocol consists of a Client
(Controlling Station) and one or more servers (Controlled Stations). The Client
constantly monitors and controls the data from each server in the TCP/IP
network.

3.1 Module Address

The 104C Module gateway is identified at transport level using the IP Address.

3.1.1 IP Address

The 104C Module gateway is identified by a unique IP address on the TCP/IP
network. You must edit the WATTCP.CFG configuration file (or use the
configuration tool) to enter a valid IP address. The following example lists the
default contents of the WATTCP.CFG file:

In this example, the 104C Module gateway is identified by IP address

192.168.0.250 in the IEC-60870-5-104 network, with a netmask (subnet mask) of

255.255.255.0 and a default gateway address of 192.168.0.1.
Remote Server Identification
The remote server is identified first by its IP address which you can enter through

the Client X section:

104C Version 3 ♦ ProLinx Gateway IEC-60870-5-104 Protocol Implementation
IEC 60870-5-104 Client (Firmware v3.xx) Protocol Manual

You may configure up to four remote servers to be communicating
simultaneously with the module.

You must also identify the Common ASDU Address in the server. This value is
identified through the Client X Sector Y section. Each server can be associated
with up to two sectors with distinct Common ASDU Addresses. The Commons
ASDU address must be greater than 0.

Protocol Manual IEC 60870-5-104 Client (Firmware v3.xx)

3.2 Monitor Direction and Control Direction: Information Object
Definition

The protocol specification defines two directions of data transmission: Monitor
direction and Control direction.

Monitor Direction: The direction of transmission from a server to the Client
(gateway)

Control Direction: The direction of transmission from the Client (gateway) to a
server

The data that is transferred from a server to a Client is known as Monitor
information objects (or Monitor points). The data that is transferred from a Client
to a server is known as Control information objects (or Control points).

The 104C Module contains an internal database of 4000 16-bit words. You must
associate the Monitor and Control information objects to database addresses in
the 104C Module. To configure the information objects for the 104C Module,
follow these steps:

1 Calculate the number of Monitor and Control information objects for the

application. The total number of monitor points must be equal or less than

1000. The total number of control points (commands) must be equal or less
than 500 points.

2 Calculate the 104C Module database regions that are required for the

application, based on the number of Monitor and Control information objects.
Define two separate regions. Remember that each data type stores a
different quantity of data (for example, M_SP_NA uses one bit, M_ST_NA
uses one byte, and so on).

3 Configure each information object within its 104C Module database region.

4 Make sure that the other parts of your application correctly update the

gateway database regions associated with the configured 104C data types,
as shown in the following illustration.

IEC-60870-5-104 Protocol Implementation 104C Version 3 ♦ ProLinx Gateway
Protocol Manual IEC 60870-5-104 Client (Firmware v3.xx)

All information objects must be configured in the correct location in the 104C
Module database in order to be properly updated by other parts of the
application. Keep the data types separated by configuring the Control information
objects and Monitor information objects in separate areas of the 104C Module
database. The following illustration shows an example configuration:

In this example, all Monitor information objects are located between database
addresses 0 and 199, and all Control information objects are located between
address 200 and 399.

3.3 Using Monitor Points

The following monitor points are supported by the 104C Module gateway:

Symbol Description Data Size in

M_SP_NA Monitored Single-Points 1 bit Bit

M_DP_NA Monitored Double-Points 2 bits Bit

M_ST_NA Monitored Step Position Points 1 byte Byte

M_BO_NA Monitored 32-Bit Bitstring Points 2 words Double word

M_ME_NA Monitored Normalized Measured Points 1 word Word

M_ME_NB Monitored Scaled Measured Points 1 word Word

M_ME_NC Monitored Short Floating-Point Measured

Points

M_IT_NA Monitored Integrated Totals 2 words Double word

Each monitor point is identified by its Information Object Address or Point # Index
(it should be unique for each Common ASDU Address in the network). For each
monitor point, configure the following parameters:

Point # - The information object address of the point. It identifies the point in the
network.

DB Address - The database location in the 104C Module gateway associated
with the point. You must associate each point to a database address in the 104C
Module gateway. The interpretation of this parameter depends on the point type

C_SE_NC Control Short Floating-Point Value Set Point Command

In addition to these the module also supports generic commands to request
specific tasks from the remote server such as clock synchronization.

Each Control information object is identified by its Information Object Address.
For each Control information object, configure the following parameters:

Point Index - This is the Information Object Address of the information object. It
identifies the information object in the network. This address must be unique for
each sector (Common ASDU Address) in the network.

DB Address - This is the database location in the 104C v3 gateway associated
with the information object. The database address interpretation may be bit­address, byte-address, word-address, double-word-address depending on the
ASDU type. Refer to the following section for further information:

The 5201-DFNT-104C module supports the mailbox feature. It allows the
Ethernet/IP (DFNT) remote device to request specific tasks from the module by
writing a data block request to the module database. The module will perform the
request and then update the mailbox response area in the database.

Mailbox Feature (x201-DFNT-104C) 104C Version 3 ♦ ProLinx Gateway
Protocol Manual IEC 60870-5-104 Client (Firmware v3.xx)

The start of the mailbox area is configured through the Mailbox Offset parameter
in the IEC-104 Client Module section as follows:

The mailbox area requires a 128-word database area. The first 64 words are
used for the mailbox request area received from the remote Ethernet/IP device.
The last 64 words are reserved for the mailbox response built by the gateway
module. So for the example above:

In the mailbox request area the first and last words are reserved for the mailbox
ID. Once the module recognizes a new mailbox ID (same mailbox ID) into these
registers it will process the mailbox request starting from the second register:

Offset Description

0 Mailbox ID

1 Start of mailbox request

… …

62 End of mailbox request

63 Mailbox ID

IEC 60870-5-104 Client (Firmware v3.xx) Protocol Manual

The same applies for the mailbox response. The module builds the mailbox
response and updates the mailbox ID according to the originating request:

Offset Description

0 Mailbox ID

1 Start of mailbox response

… …

62 End of mailbox response

63 Mailbox ID

The following mailboxes are supported by the module:

±9902 Command Control Block (Add command to Command Queue)

±9903 Event Messages from Outstations

±9250 General Module Status

±9970 Get 104 client driver's time

±9971 Set 104 client driver's time

±9997 Reset status data

9998 Cold boot Confirmation

9999 Cold Boot Request

The purpose for the mailbox supporting a positive and negative value is so the
remote device can trigger consecutive requests for the same mailbox by
switching the value between positive and negative. For example, to request 3
consecutive Get Module time the block ID could be switched as +9970, -9970,
+9970.

5.2 Using ProSoft Configuration Builder (PCB) for Diagnostics

The Configuration and Debug menu for this gateway is arranged as a tree
structure, with the Main menu at the top of the tree, and one or more sub-menus
for each menu command. The first menu you see when you connect to the
gateway is the Main menu.

Because this is a text-based menu system, you enter commands by typing the
[command letter] from your computer keyboard in the Diagnostic window in
ProSoft Configuration Builder (PCB). The gateway does not respond to mouse
movements or clicks. The command executes as soon as you press the

[

], a new screen will be displayed in your terminal application.

5.2.1 Required Hardware

You can connect directly from your PC’s serial port to the serial port on the
gateway to view configuration information, perform maintenance, and send or
receive configuration files.

ProSoft Technology recommends the following minimum hardware to connect
your PC to the gateway:

 80486 based processor (Pentium preferred)
 1 megabyte of memory
 At least one UART hardware-based serial communications port available.

USB-based virtual UART systems (USB to serial port adapters) often do not
function reliably, especially during binary file transfers, such as when
uploading/downloading configuration files or gateway firmware upgrades.

5.2.2 Using the Diagnostic Window in ProSoft Configuration Builder

Tip: You can have a ProSoft Configuration Builder Diagnostics window open for more than one
module at a time.

1 Click to configure the connection. On the Connection Setup dialog box, select

a valid com port or other connection type supported by the gateway.

2 Verify that the null modem cable is connected properly between your

computer’s serial port and the gateway. A regular serial cable will not work.

3 On computers with more than one serial port, verify that your communication

program is connected to the same port that is connected to the gateway.

If you are still not able to establish a connection, contact ProSoft Technology for
assistance.

5.2.3 Navigation

All of the submenus for this gateway contain commands to redisplay the menu or
return to the previous menu. You can always return from a submenu to the next
higher menu by pressing [M] on your keyboard.

The organization of the menu structure is represented in simplified form in the
following illustration:

The remainder of this section shows the menus available for this gateway, and
briefly discusses the commands available to you.

Keystrokes

The keyboard commands on these menus are usually not case sensitive. You
can enter most commands in lowercase or uppercase letters.

The menus use a few special characters (?, -, +, @) that must be entered exactly
as shown. Some of these characters will require you to use the SHIFT, CTRL, or

ALT keys to enter them correctly. For example, on US English keyboards, enter

the ? command as SHIFT and /.
Also, take care to distinguish the different uses for uppercase letter "eye" (I),

lowercase letter "el" (L), and the number one (1). Likewise, uppercase letter "oh"
(O) and the number zero (0) are not interchangeable. Although these characters
look alike on the screen, they perform different actions on the gateway and may
not be used interchangeably.

Redisplaying the Menu

Press [?] to display the current menu. Use this command when you are looking
at a screen of data, and want to view the menu choices available to you.

5.2.4 Main Menu

When you first connect to the module from your computer, your terminal screen
will be blank. To activate the Main menu, press the [?] key on your computer’s
keyboard. If the module is connected properly, the following menu will appear.

Caution: Some of the commands available to you from this menu are designed for advanced
debugging and system testing only, and can cause the gateway to stop communicating with the
processor or with other devices, resulting in potential data loss or other communication failures.
Use these commands only if you fully understand their potential effects, or if you are specifically
directed to do so by ProSoft Technology Technical Support Engineers.
There may be some special command keys that are not listed on the menu but that may activate
additional diagnostic or debugging features. If you need these functions, you will be advised how to
use them by Technical Support. Please be careful when pressing keys so that you do not
accidentally execute an unwanted command.
