This section is used to define the general parameters of Modbus TCP. The means of
the fields are:
In the field "IP Address" the IP address of the converter is defined;
In the field "SubNet Mask" the Subnet Mask of the converter is defined;
In the field "Gateway" the default gateway of the net is defined. This feature

for going out of the net;

Checking "Enable UDP
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 );
