hi, thanks for your answer.
NModbus4 is free? How about EasyModbusTCP/UDP/RTU .NET?

Yes, it is distributed under the MIT license which means you must include a copy of the license. EasyModbus is Open Source.

On voulant faire la communication du coupleur 750-342 1er version(menu d'une borne 750-494 et +) j'ai utilisé un code socket avec C# ou bien Node Js. je sais pas si ma démarche est exacte :
Je rencontre l'erreur http/1.1 501 pourrez-vous m'aider. je cherche au final de lire les données et les envoyer dans une base de données afin de les traités etc

bonne journée

I'm not directly involved in ModBus development, only building of packages that contain it, so I'm afraid I can not help you with this!
