SET COMMUNICATION:
This section define the fundamental communication parameters of HART and Modbus
buses.
By Pressing the “
Set Communication
” button from the main window for SW67908 (Fig.
2) the window “Set Communication” appears (Fig. 3).
The means of the fields for the “HART Master” section are:
In the field “
Address
” the type of Master is defined;
In the field “
Retry Limit
” the maximum number of retries in case of missing
response from HART device is defined;
The means of the fields for the “Modbus Slave” section are:
In the field “
Baudrate
” the baudrate for the serial line is defined;
In the field “
Parity
” the parity of the serial line is defined;
In the field “
Stop Bits
” the number of Stop Bits of the serial line is defined;
In the field “
ID Device
” the ID of Modbus side of the converter is defined (only if
“Asynchronous” mode is set);
If the field “
Read with Input Register / Status Function
” is checked, it is
possible to read the data from HART side with Input Registers (Function 04) and
write the data to publish on HART side with Holding Registers (Function 06/16). The
Output data are readable with Function 03. Otherwise, only Holding Registers will
be used and the Output data of HART side cannot be read back.
