With the webpage, you can add new TIC command with ModBus registry address.
Go to "Tools" and "ModBus" button then click on "registres_spec.json"

Then you get a Json file like :

{
"historique":[{
		"reg":1,
		"command":"xxxx",
		"size":4,
		"type":"numeric"
		}

"standard":[{
		"reg":1,
		"command":"xxxx",
		"size":4,
    "type":"string"
		}
	      ]
}

With this file, you can add new TIC command with historic or standard mode.

• reg : Registry address
• command : TIC command (for ex : DATECOUR)
• size : max size value of the command
• type : value type (only "string" or "numeric"

Click to "save" to validate
