NEW CONFIG RATION / OPEN CONFIG RATION:
The “New Configuration” button creates the folder which contains the entire device’s configuration
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 COMM NICATION:
This section defines the fundamental communication parameters of two Buses, Modbus
and Modbus TCP.
By pressing the “Set Communication” button from the main window for SW67508 (Fig
2) the window “Set Communication” appears (Fig 3)
The section “Operation Mode” defines the operation of the Converter in “Routing Mode”
or “NAT Mode” (see the description at page 20)
The means of the fields for “Modbus TCP Slave” are:
In the field “IP Address” the IP address of Modbus TCP side of the converter is
defined;
In the field “Subnet Mask” the SubNet Mask of Modbus TCP side of the converter
is defined;
In the fields “GATEWAY” the default gateway of the net 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 DP 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 RTU line as is If you don’t want to
send the first two bytes (0x55, 0xAA) in the RTU line it is possible to check the field
“Cancel the first two bytes”;
If the field “No TCP frame on RT Timeout” is checked, the Converter don’t
sends back the reply on TCP (error response) if the Slave RTU interrogated has not
replied

If the field “Fast Start p (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 for the fields of “Modbus Master” are the same for all the Device Type:
In the field “Serial” the type of serial port is defined;
In the field “Baudrate” the data rate of Modbus RTU is defined;
In the field “Parity” the parity of Modbus RTU is defined;
In the field “Stop bits” the number of Stop-Bit of Modbus RTU is defined;
In the field “Data bits” the number of Data Bit of Modbus RTU is defined;
In the field “Timeout” the maximum time that the converter attends for the answer from the Modbus slave interrogated is defined;
In the field “Communication Idle Time (ms)” the delay between the Modbus response from a slave and the following request is
defined;
In the field “Time Between Bytes (ms)” a custom delay between the bytes of Modbus frames can be set;
If the field “Modbus Filter” is checked, the wrong responses received from Modbus side are discharged

OPERATION MODE:
R O TING :
A few characteristics of the Modbus RTU package have been modified in the standard of the Modbus TCP protocol Two bytes of the final CRC
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 RTU 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 RTU slave responds with an exception, that exception code will be transmitted again to the TCP master If the RTU slave does not
respond in the estimated time defined by the Timeout parameter, an exception response will be given: error code $0B
N ATTING :
When using the operation mode, Natting, the requested data will be processed through a table of translations of the Modbus network
addresses
