Note: the set data for the host computer and the inverter must be the same.
Communication address
of this unit
1 to 247, 0 for broadcast
address
When the master is in the write-frame, the communication address of the slave is set to
0, that is the broadcasting communication address, all slaves on MODBUS will accept
the frame, but the slave does not respond. Note that the slave's address can not be set to
0.
The communication address of this unit has uniqueness in the communication network,
which is the basis of peer-to-peer communication for the host computer and the
inverter.
Communication response
delay
Response delay: it refers to the interval time from the end of the inverter receiving data
to the start of it sending response data to the host machine. If the response delay is less
than the system processing time, then the response delay time is subject to the system
processing time; If the response delay is longer than the system processing time, after
the system finises the data processing, and continues to wait until the response delay
time, and then sends data to the host computer.
Communication timeout
fault time
0.0 (invalid) ; 0.1 to 100.0s
Communication time-out parameter is not valid when the function code is set to 0.0s.
When the function code is set to valid, if the interval time between one communication
and the next communication exceeds the communication time-out time, the system will
report communication failure error (E.CE) .
Generally, it is set to invalid. If the parameter can be set to monitor the communication
