Only licensees are permitted to copy verbatim copies of this license document, but changing it is not allowed.
Promodbus is a commercial spin-off of the libmodbus project.
The purpose of this edition is to enable professionals to market their products using the Modbus library without the constraints of the LGPL, and to fund the development of the Open Source version called libmodbus.
The license keys correspond to purchases that Stéphane Raimbault or Webstack company can verify through their own application, and then authorize or revoke the license. There is no automatic check of the validity of the licence by the Promodbus runtime. The license keys are just used for administrative tasks such as to facilitate the license renewal. Promodbus is designed to run on secured environment and will never make queries to external licence control services.
The libmodbus code is owned by Stéphane Raimbault and contributions are only accepted under the conditions of the Contributor License Agreement.
