This parameter is used to set the data transmission rate between the host computer and the inverter. Note that the
baud rate set by the host computer and the inverter must be the same, otherwise, the communication cannot be carried
out. The higher the baud rate, the faster the communication speed .
The data format set by the host computer and the inverter must be consistent, otherwise, the
communication cannot be carried out.

The local address is unique, which is the basis for realizing point-to-point communication between the host computer
and the inverter.

0.0 s ~ 600.0 s
When this parameter is set to a valid value, if the interval between one communication and the next communication
exceeds the communication timeout time, the system will report a communication failure error. Normally, it is set to
invalid. If this parameter is set in a continuous communication system, the communication status can be monitored.
