Using this function, the converter can be seen like more than one serial Modbus slave. Each serial Modbus slave is a row of the table and it is
possible to define to which TCP device is linked.
By pressing the “
Translate Table
” button from the main window for SW674-A003 (Fig. 2) the window “Set Translate Table” appears (Fig.
6).
The data of the columns have the following meanings:
In the field “
Slave ID
” the ID of the virtual Modbus slave device created by the converter is defined;
In the field “
IP
Address TCP
” the IP address of the Modbus TCP slave device to which address the TCP requests is defined;
In the field “
Slave ID TCP
” the station ID of the Modbus TCP slave device to which address the TCP requests is defined;
If the field “
Reserved Socket
” is checked, the converter will reserve a socket for the specific Modbus TCP slave. This socket will be
closed only after the number of consecutive errors defined in the “
Errors Sock
” column. It is possible to reserve up to 3 sockets for 3
different Modbus TCP slaves (function available only for Hardware Version with Dip-Switches);
If the option “
UDP
” is checked, Modbus over UDP communication is enabled;
If the option “
Broadcast
” is checked, the broadcast requests for that slave are accepted;
In the field “

” a brief description is defined.
