” the serial port to use is defined (RS232 or RS485);
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;
If the field “
Read with Input Register / Status Function
” is checked, it is possible to
read the Input bytes of OPC UA side with Input Registers (Function 04) and write the
Output bytes of OPC UA side with Holding Registers (Function 06/16). The Output bytes
