1. Introduction

The FD-80 Fieldbus Adapter Profibus DP slave, is a simple and cost effective way of
connecting different Profibus DP networks through Ethernet LAN with TCP/IP protocol.

The FD-80 can be configured to send the desired amount of data which is transparently
transferred between different Profibus DP networks via the Ethernet 10Base-T interface.

There are two different types of FD-80 devices:

• Point to point, the FD-80 (P) transfers continuously specified Profibus DP data from
the input/output buffers over Ethernet using TCP/IP.

• Addressed, the FD-80 (A) is the Ethernet TCP/IP master which exchanges specified
Profibus DP data with addressed remote FD-80 (P).The data frames include the
address of the selected remote FD-80 (P).

6.4 Configuration

The device specific functionality and Profibus DP settings of FD-80 can be configured by
using FD-Tool (PC based software), either on-line or off-line.
The Ethernet network with TCP/IP protocol settings can be configured by using the
Telnet protocol.

6.4.1 DIP switch settings

The FD-80 has no DIP switch settings.

6.4.2 On-line configuration by FD-Tool

This part will only describe the usage of FD-Tool to perform the configuration.
For FD-Tool installation and general FD-Tool handling, see “FD-Tool installation manual”.

Service port of FD-80

The FD-80 goes into configuration mode (connection with FD-Tool) immediately
after a power on. The default setting of FD-80 service port, used for configuration
with FD-Tool is:

IP-address 10.0.0.10 Subnet mask 255.0.0.0 Port number 8000 Connection State FREE
These default settings can be modified before initiating communication between FD-Tool

and the FD-80, under Settings > Communication port and language settings >

TCP/IP.

Note 1: The IP-address and subnet mask can be changed by using Telnet, but to get access to

service port of FD-80 by FD-Tool, the IP-address and corresponding subnet mask has
to be the same as set by using Telnet.

Note 2: To get access to the service port, the FD-80 must be set to standard TCP/IP mode

(Connection state FREE), set by the Ethernet network configuration (see 6.4.5).

Note 3: The PC’s subnet mask setting must be the same as the FD-80 subnet mask setting,

but the PC’s IP-address must be different from the FD-80’s IP-address, to get access
to FD-80 by FD-Tool.

Initiate an on-line configuration

• Start the FD-Tool.

• Connect a crossover cable (or a straight cable if a switch/hub is used)
to the Ethernet-port of the PC and the service port of the FD-80.

• Initiate communication between the FD-Tool and the FD-80 by selecting Connect >
TCP/IP. The FD-80 will attempt to get communication until a successful connection
or a manual cancel.

• Power the connected FD-80. After some seconds, the connection will established and
the Status (to the left in the lower border of FD-Tool window) will be changed from
Disconnected to Connected.

• The FD-Tool shows the device type of this FD-80, present configuration, the default
configuration and whether or not the FD-80 is being used for the first time.

12 6630-2281

6.4.5 Ethernet network configuration by using Telnet

The FD-80 is always available for configuration of the TCP/IP protocol settings, by using
the Telnet network protocol. The default setting of FD-80 service port, for configuration
by using Telnet is:

IP-address 10.0.0.10 Subnet mask 255.0.0.0 Port number 1111
To select the configuration menu, start the Telnet client and use the parameters above,

e.g. under the DOS prompt enter Telnet <IP-address> 1111.
When the connection has been established you will see the following menu in your

Telnet window:

************************

effective without Save Setup after exiting the menu.

136630-2281

SETUP Port 0 (Serial)

UART Setup Settings of the internal serial port TCP/IP control interface, internal-

ly connected to the Profibus DP slave control. This is set by default
to 38,400 bit/s, no parity, 8 data bits and 1 stop bit, and should not
be changed while the internal serial port of Profibus DP slave con­trol has the same default setting.

SETUP Port 0 (Serial) > TCP/IP Mode > Box to Box

Permanent TCP connection is opened between a Master and Slave port. It makes no dif­ference which port is the Master and which the Slave. The Master port functions as a
TCP client and is therefore responsible for opening and closing.

Slave Port Port of the FD-80 Slave port, in range A to D and -. Only for the

master port, where it should be set to A.

Slave IP-Address IP-address of the FD-80, to which Slave port is located. This is set

only for Master port.

SETUP Port 0 (Serial) > TCP/IP Mode > IP Bus Mode

Several FD-80s logically linked together over the network in the
form of Master-Slave bus, where the Master sends data by broad­cast and the Slaves send back data addressed to the Master. Any
additional data traffic or other network protocols have no effect on
the connection.

Master: Subnet IP Network address of the subnet in which the Master and Slaves are

located. This is set only for the Master.

Slave: Master IP IP-address of the Master. This is set only for the Slaves.

SAVE Setup

All changes will be saved in non-volatile memory. All settings are
activated only after a SAVE Setup. If closing the Telnet connection
without saving, the FD-80 retains all the settings it had before open­ing the configuration menu.

7.2.2 Profibus DP I/O data

Ordinary Profibus DP input and output data are used by FD-80 (A), with one additional
serial transfer command word at “out data”, and one status word at “in data”.

2 Out word 1, high byte Out word 1, low byte
–– –
–– –

64 Out word 63, high byte Out word 63, low byte

7.2.2.1 Output data word

Data transmitted from Profibus DP master to FD-80. The first word is the added com­mand word and the remaining 1 to 63 words are ordinary output data sent to the
addressed remote Fieldbus Adapter.

Output word 1 high byte (bit 15..8) is the serial transfer command byte, with following
content:

EN ENable the FD-80 (bit15).

This bit must always be set high (1) for normal operation.
When it is set FD-80 indicates data set ready by the EN
bit being set in the Input status word. The EN bit is only
set to low (0) to disable the FD-80.

SDO Send actual Data Once, toggle bit (bit 14).

When this toggle bit is changed, the data words are
taken from the DP data words and transmitted directly
over the serial transfer interface of the FD-80.

CNF CoNFiguration mode (bit 12).

For testing purpose only.
This bit is set low (0) during the normal operating mode
of the FD-80. This bit is set high (1) in order to switch
the FD-80 over from normal operating mode to configu­ration mode.

RES RESet read back status, toggle bit (bit 11).

When this toggle bit is changed, it will reset read back
status ACK and TO also in all data words.

Output word 1 low byte (bit 7..0) is the serial transfer address, with the following con­tent:

Transfer slave address of the Fieldbus Adapter to which this frame will be sent. Serial
transfer slave address, range is 1 to 64.

Output word 2 to 64 is the output data, with following content:
Word 1 High: Output byte 1 Low: Output byte 2

Word 2 High: Output byte 3 Low: Output byte 4

......... ......... ........

Word 63 High: Output byte 125 Low: Output byte 126.

7.2.2.2 Input data word

Data is transmitted from the FD-80 to the Profibus DP master. The first word is the
added status word and the remaining 1 to 63 words are ordinary input data received
from the output word addressed remote Fieldbus Adapter.

Input word 1 high byte (bit 15..8) is the serial transfer status byte, with following con­tent:

ST STatus of serial transfer command FD-80 (bit15).

Set to high (1) when the received command has been

accepted by the FD-80. Set to low (0) if the received

command has not been accepted.
DV Data Valid (bit 13).

For testing purpose only.

Acknowledgement of the command CNF.
ACK ACKnowledgement of serial transfer (bit 11).

Set to high (1) when serial transfer sent output data to a

remote FD-80 has resulted in a received frame with input

data from the remote FD-80.
TO Time Out of serial transfer (bit 10).

Set to high (1) when the last serial transfer of output

data to a remote FD-80 has not resulted in any received

frame within 1,500 ms.
Input word 1 low byte (bit 7..0) is not used.
Input word 2 to 64 is the input data, with following content:
Word 1 High: Input byte 1 Low: Input byte 2
Word 2 High: Input byte 3 Low: Input byte 4

........ ......... .......

Word 63 High: Input byte 125 Low: Input byte 126.

7.2.2.3 Profibus DP communication

This describes the required Profibus DP communication sequence, from a Profibus DP
master unit to FD-80 (A), to get access and data exchange with remote Fieldbus
Adapters.

Preparing for data exchange:

1. Enable normal operation access with FD-10 by command EN
Out word 1, bit 15.

2. Verify accepted EN command by checking status ST.
In word 1, bit 15.

Data exchange with a remote Fieldbus Adapter :

1. Set the Transfer slave address.
Out word 1, low byte.

2. Set Out data (up to 63 word) to this Transfer slave.
Out word 2 ...64.

3. Reset last received Input data and status by the command RES.
Out word 1, toggle bit 11.

4. Transmit output data over serial transfer line by the command SDO.
Out word 1, toggle bit 14.

5. Verify correct sent and received data by checking status ACK.
In word 1, bit 11 is high (1). Alternatively, incorrect sent and received data,has not
been received within 1,500 ms by checking status TO.
In word 1, bit 10 is high (1).

6. If correct received data (ACK OK)
Read In data (up to 63 word) from this Transfer slave TO.
In word 2 ...64.
