Json file for a Ducobox

[AlexB64]

Here is example for nod1 for one input register and one holding register from the table.

Make sure to fallow this:
Because of a difference in some ModBus implementations compared with the
official specification (on which our implementation is based), an address shift
of ‘1’ can occur for the read and write parameters.
For example: read address ‘20’ will be ‘19’.
This can be solved by setting the >RegOffs parameter to ‘1’ using the
display menu or the Duco Network Tool.


You can use RTU read test before you play with profile to make sure all connection are OK and you get the values.
Each time you make a change in profile you must delete the device from HL, delete the profile and then add new profile and add new device.

Thanks ! that's gonna help me a lot for sure

Have a good day !
