SET COMMUNICATION:
This section defines the fundamental communication parameter of two buses, PROFIBUS and Modbus
TCP.
By pressing the “
Set Communication
” button from the main window for SW67579 (Fig. 2) the
window “Set Communication” appears (Fig. 3).
The window is divided in two sections, one for the PROFIBUS and the other for the Modbus TCP.
The means of the fields for “PROFIBUS” are:
In the field “
ID Dev.
” the address of the PROFIBUS side is defined;
In the field “
Baud rate
” the baud rate for the PROFIBUS side is defined.
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 field “
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;
If the field “
Read with Input Register / Status Function
” is checked, it is possible to read
the Input bytes of PROFIBUS side with Input Registers (Function 04) and write the Output
bytes of PROFIBUS side with Holding Registers (Function 06/16). The Output bytes are
readable with Function 03. Otherwise, only Holding Registers will be used and the Output
bytes of PROFIBUS side cannot be read back.
