A device’s configuration can also be imported or exported:
To clone the configurations of a programmable “ Modbus TCP Slave / Modbus Master -
Converter” in order to configure another device in the same manner, it is necessary to
maintain the folder and all its contents;
To clone a project in order to obtain a different version of the project, it is sufficient to
duplicate the project folder with another name and open the new folder with the
button “Open Configuration”.

SET COMMU ICATIO :
This section define the fundamental communication parameters of two buses,
Modbus TCP Slave and Modbus Master.
By Pressing the “Set Communication” button from the main window of SW674-
A002 (Fig. 2) the window “Set Communication” appears (Fig. 3).
The section “Operation Mode” defines the operation of the Converter in “Routing
Mode” or “ AT Mode” (see the description at page 17).
The means of the fields for the “Modbus TCP Slave” section are:
In the fields “IP ADDRESS” the IP address of Modbus TCP side of the
converter is defined;
In the fields “SUB ET Mask” the SubNet Mask of Modbus TCP side of the
converter is defined;
In the fields “GATEWAY” the default gateway of the network is defined. This
feature can be enabled or disabled pressing the Check Box field. This feature
is used for going out of the net;
In the field “Port” the port used for Modbus TCP communication is defined;
Checking “Enable UDP Port” field it is possible to do a Broadcast request.
This request must be made at Port 64223 ($FADF) with these six byte of
data: $53, $45, $41, $52, $43, $48. Each device in response sends a total of
10 Bytes. These bytes are four for the IP and the other for the MAC address
(Example of response: 0xC0, 0xA8, 0x01, 0x2A, 0x11, 0x22, 0x33, 0x44,
0x55, 0x58. So the IP is: 192.168.1.42; and the MAC Address: 11-22-33-44-
55-58 );
If the field “Enable Special Command” is checked, it is possible to send a
no-Modbus request through the Converter. i.e. a TCP frame with the first two
characters 0x55 and 0xAA is sent in the Modbus TU line as is. If you don’t
want to send the first two bytes (0x55, 0xAA) in the TU line it is possible to
check the field “Cancel the first two bytes”;

If the field “ o TCP frame on RTU Timeout” is checked, the Converter don’t sends back the reply on TCP (error response) if the
Slave TU interrogated has not replied.
If the field “Fast StartUp (only 100Mb/s)” is checked, the Converter take less time to go online. This command can use only if the
Converter is used in a 100Mb/s network;
The means of the fields for the “Modbus Master” section are:
In the field “Baudrate” the baudrate for the serial line is defined;
In the field “Parity” the parity of the serial line is defined;
In the field “Stop Bits” the number of Stop Bits of the serial line is defined;
In the field “Data Bits” the number of Data Bits of the serial line is defined;
In the field “TimeOut (ms)” the maximum time that the converter attends for the answer from the Slave interrogated is defined;
In the field “Communication Idle Time (ms)” the delay (idle time) between two Modbus requests is defined.

OPERATIO MODE:
R OUTI G :
A few characteristics of the Modbus TU package have been modified in the standard of the Modbus TCP protocol. Two bytes of the final C C
were eliminated (no longer necessary for the information to reach its already corrected destination). The first byte of the slave identification
was changed, leaving the one that is called PDU. A frame denominated as MBAP header with dimensions of 7 bytes was added to the head of
the PDU.
It is composed by the following:
Word transaction identifier (recopied from the slave in the response phase);
Word protocol identifier (0=Modbus protocol);
Word length (number of successive bytes);
Byte unit identifier (used for the routing operation).
By using the last byte of the MBAP header, it is possible to carry out the routing from a requested Modbus TCP toward a serial line using the
address from the slave which is specified by the byte unit identifier.
Example:
A requested Modbus TCP made in the device as the address 192.168.0.200 for the holding register address $2000, which is MBAP unit
identifier has the value of 2. It will be followed by the request on the serial for the device with the address 2 at the word $2000.
After the request is made, the TU will respond. The master TCP will be given the same response which will be reconstructed according to
the specifications of the Modbus TCP.
If the TU slave responds with an exception, that exception code will be transmitted again to the TCP master. If the TU slave does not
respond in the estimated time defined by the Timeout parameter, an exception response will be given: error code $0B.
ATTI G :
When NAT operation mode is used, the requested data will be processed through a table of translations of the Modbus network addresses.
