Problem Modbus profile Kostal - sorrow - 14.02.2019
hello i want to read the voltage from a Kostal Inverter, i use this Modbus profile but i have a false values, i think the Modbus Addresse are false?
{
"bus_datatype": 14,
"address": 148,
"type": "register",
"units": "V",
"name":"AC Spannung Phase L1-L2 value",
"datatype": "float32"
},
{
"bus_datatype": 14,
"address": 164,
"type": "register",
"units": "V",
"name":"AC Spannung Phase L2-L3 value",
"datatype": "float32"
},
{
"bus_datatype": 14,
"address": 170,
"type": "register",
"units": "V",
"name":"AC Spannung Phase L1-L3 value",
"datatype": "float32"
},
RE: Problem Modbus profile Kostal - admin - 14.02.2019
First register address should be 158, not 148. Do you get anything in Error logs or Modbus error log (depending on FW version). Have you set device port to 1502 (default is 502) and slave id to 71?

i get any error logs, and i set device port to 1502 (default is 502) and slave id to 71 but the values are false

You need to set correct read_swap in your profile. Try "b", "n" or "bw"

Thank you Admin that work now with non Swap

Hello there,
I also have problems communicating with the KOSTAL PLENTICORE investor.
I have loaded the profile that I attach in this post, but I do not receive data from the inverter, I do not know if the problem is the modbus addresses or what the problem may be.
Has anyone managed to correctly read the data of this inverter?
Thank you.
RE: Problem Modbus profile Kostal - admin - 30.09.2021
Does it work when using Read test? Check if port/slave id is correct.

But, the reading test is for RTU, not for TCP, right?
RE: Problem Modbus profile Kostal - admin - 01.10.2021
2021 RC2 FW has Read test for both TCP and RTU

Hi Sorrow,
how have you managed to import your profile? If I trying it I getting the attached error message.
Could this be the problem?
Best Regards
Steffen

Hi @all
here is my short profile of the important values for my usage. I tested it and it works fine. It can be easily adopted.
Best Regards
Steffen

Hi, I have updated the FW to 2021 RC2 and now I can do test for TCP from the Kostal inverter.
For example if I query register: 514 , it gives me the current battery charge value correctly.
But when I make the map, it does not give me any value.
The register I am trying to map is:
{
"name": "Battery current SOC",
"bus_datatatype": "uint16",
"address": 514,
"writable": 0,
"unit":"%"
}
In KNX I have created a Virtual group address at address 32/3/3 type 2 bytes unsigned integer.
Why the test works and reads the value correctly but when I do the mapping I don't get the value?
Thank you.

Problem Solved.
Attached is the json profile of the Kostal Plenticore Inverter.
I hope it will be helpful.
