Modbus profiles examples

[Daniel]

Try this:

Code:

{   
      "bus_datatype": "int64",
      "address": 20480,
      "type": "register",
      "units": "kWh",
      "value_multiplier": 0.01,
      "name": "Active import",
      "datatype": "uint64"
    },

Try using profile generator if this is simpler.

I´ve tested it but it doesnt work. Here are some pictures. I always get a "operation time out", but the read test works!

What are the RTU settings?

[Dré]

LM does not have D0/D1 markings, but A/B/GND. A is positive, B is negative. Try swapping A/B lines and also check that the serial port settings match.

now the communikation works!

I´ve found the manufactur manual with chapter 9 (Communication with Modbus) inside.

Here are the fields: Quantity, Details, Start reg (hex), Size, Res., Unit, Data type,

for Example:

Quantity: Active import, Details: Tariff 1, Start reg (hex): 5170, Size: 4, Res.: 0,01, Unit: kWh, Data type: Unsigned

When i try reading Active import with these settings:
- Function: Holding register (#3)
- Address: 20480
- Data type: uint64
- Read swap: Word

the Answer is 94425 (i think its 944,25 kWh), that is correct.

but how i have to "translate" for the Logicmachine? I know, that i have to calculate hex into dec (like 5000 in hex is 20480 in dec). In the Modbus Profile Generater are Fields like bus_datatype, datatype, value_custom, read_swap...

Can you give me an example? Thankx

I have the ABB B21 and have the next script what is working, maybe this can help you?

The last read_delay is because is had 2 devices and the next device i activate didn't work

FYI: I've just implemented and written a modbus JSON profile for the FLEXIT NORDIC S4 ventilation system. Now I can retrieve vital information and change certain parameters. PM if you are in need of this for your flexit. (PS! The CI66 JSON did not work for me).

Hello, I have also tried the CI66 JSON with no success. Are you interested in sharing your file that would be great

My unit is a Flexit Uni 4

Hallo,
I created this modbus profile, but if I try to import it in LM, it show me "invalid profile":

Profile is missing datatype fields, most likely kWh readings will be incorrect. Can you provide documentation for this device?

Hello,
I inserted them like uint32.

Thank you

[pritorianz]

Hi all!
I made and checked the profile for the Haier YCJ-A002 module (for connecting Haier air conditioners via Modbus).
For writing, I used the site https://jsoneditoronline.org/
And modbus profile generator https://forum.logicmachine.net/showthrea...8#pid19678
