SET COMMUNICATION:

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
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 UDP
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

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
