Modbus profile generator

[Daniel]

Yes, just create new sheet, name it and use in the custom_value field. You can add as many you want.

Nice work thank !
Just a precision for others, I used office 13 and doesn't work.
I upgrade to 2016 and perfect working !

I created a profile with modbus profile generator,but I'm not sure that i did it correctly would you guys check it for me please ?

Code:

{
  "manufacturer": "YORK",
  "description": "HA-MA164AD",
  "mapping": [
    {
      "name": "Indoor Unit Setpoint Temperature C\u00B0",
      "address": 1,
      "bus_datatype": "uint32",
      "datatype": "uint32",
      "type": "register",
      "units": "A",
      "writable": "true"
    },
    {
      "name": "Indoor Unit Mode Selection",
      "address": 2,
      "bus_datatype": "uint32",
      "datatype": "uint32",
      "type": "register",
      "units": "A",
      "writable": "true"
    },
    {
      "name": "Indoor Unit Fan Speed",
      "address": 3,
      "bus_datatype": "uint32",
      "datatype": "uint32",
      "type": "register",
      "units": "A",
      "writable": "true"
    },
    {
      "name": "Indoor Unit Control Mode",
      "address": 4,
      "bus_datatype": "uint32",
      "datatype": "uint32",
      "type": "register",
      "units": "A",
      "writable": "true"
    },
    {
      "name": "Indoor Unit On/OFF",
      "address": 1,
      "bus_datatype": "bool",
      "datatype": "uint32",
      "type": "coil",
      "units": "A",
      "writable": "true"
    }
  ]
}

The datatype and bus_datatype for your registers are uint16. For Coil you can delete datatype.
Use Read test tool to check it if all is correct. It is possible that you will have to shift registers by 1 as we starting to count from 0.

Also writable value should be true without quotes otherwise newer firmware won't accept the profile. Addressing starts with 0 and for mode/speed registers you can use 1 byte (uint8) data type.

Code:

{
  "manufacturer": "YORK",
  "description": "HA-MA164AD",
  "mapping": [
    {
      "name": "Indoor Unit Setpoint Temperature",
      "address": 0,
      "bus_datatype": "uint16",
      "datatype": "uint16",
      "type": "register",
      "writable": true
    },
    {
      "name": "Indoor Unit Mode Selection",
      "address": 1,
      "bus_datatype": "uint8",
      "datatype": "uint16",
      "type": "register",
      "writable": true
    },
    {
      "name": "Indoor Unit Fan Speed",
      "address": 2,
      "bus_datatype": "uint8",
      "datatype": "uint16",
      "type": "register",
      "writable": true
    },
    {
      "name": "Indoor Unit Control Mode",
      "address": 3,
      "bus_datatype": "uint8",
      "datatype": "uint16",
      "type": "register",
      "writable": true
    },
    {
      "name": "Indoor Unit On/Off",
      "address": 0,
      "bus_datatype": "bool",
      "type": "coil",
      "writable": true
    }
  ]
}

Hello again;

When try to upload new profile i got this error message.

[admin]

Attach your profile file. Seems like a copy/paste error.

[mkaymak]

Here it is.

[admin]

Try the attached profile. Copied profile had different space characters which are not allowed. Also there were some errors in the profile definition.

HI I HAVE AN ISSUE WITH PROFILE GENRATOR WHEN I TRY TO GENERATE JSON FILE I GET ERROR

value_custom must be null if empty

[mellotron]

Bonjour, j'ai un problème avec le générateur de profil lorsque j'essaye de générer un fichier JSON, j'obtiens l'erreur
« 9 ». s'il vous plaît, comment puis-je le résoudre.

value_custom doit être nul s'il est vide

je have fill the empty custom value but get the same issue

[Daniel]

I just set all your custom_value to null and it worked, you probably did some typo in name.

Hi,

I’m trying to write the configuration for the following Modbus device but haven’t been able to get it right, so I’d appreciate your help.
When each register holds an 8-bit value and two registers together form a 16-bit integer, how should I define it?

Register addresses (hex)ataByte Size
• 0x1C: Temperature (Low Byte):1 byte
• 0x1D: Temperature (High Byte): 1 byte
–15.0 °C to 90.0 °C (raw values 0xFF6A to 0x0384)

My failed Configration :
[
  {
    "bus_datatype": "int16",
    "datatype": "int16",
    "address": 28,
    "read_count": 2,
    "units": "°C",
    "type": "register",
    "value_multiplier": 0.1,
    "name": "Temperature"
  }
]

Thank you for reading.

[Daniel]

One register is 16bit value already, just specify datatype correctly. Do not use read_count unless you do a block read.
LM will automatically decide how many registers to read based on the datatype definition but for int16 it is just one register.

See this, much better than this old solution
