0; the broadcast address is the
communication address. All slaves on the
MODBUS fieldbus can receive the frame, but
the salve doesn't answer.
The communication address of the inverter is
unique in the communication net. This is the
fundamental for the point to point
communication between the upper monitor
and the inverter.
Note: The address of the slave cannot set to
0.

ratio
Set the digital transmission speed between
the upper monitor and the inverter.
0: 1200BPS
1: 2400BPS
2: 4800BPS
3: 9600BPS
4: 19200BPS
5: 38400BPS
6: 57600BPS
Note: The baud rate between the upper
monitor and the inverter must be the same.
Otherwise, the communication is not applied.
The bigger the baud rate, the quicker the
communication speed.

The data format between the upper monitor
and the inverter must be the same.
Otherwise, the communication is not applied.
