Modbus Goodwe

[Amelie]

I want to communicate through Modbus with my Goodwe inverter. 

I've found on the site of Goodwe how I can connect: Goodwe and the Modbus register here.

The connection on the logic machine is shown in attachement.


My json looks as follows: 

Code:

{
"manufacturer": "Goodwe",
"timeout": 3,
"read_delay": 1,
"description": "GW8k-ET",
"mapping": [
    { "bus_address": "1/7/50",
    "name": "Opbrengst PV - 1",
    "bus_datatype": "9",
    "datatype": "uint16",
    "read_count":1,
    "type": "inputregister",
    "value_multiplier": 0.1,
    "address": 0539 }
]
}

But, I get the error: Operation timed out. What Am I doing wrong?

Thank in advance!
