The uMODBUS Toolkit by Cypherbridge Systems is a comprehensive software solution that supports Modbus standard TCP, RTU, and Modbus Secure TLS protocols. It is designed to interface with platform data, sensors, and actuators used in factory automation, industrial control, energy sector, and smart building control systems. The toolkit implements the MBAPS (Modbus/TCP Security Protocol Specification), encapsulating Modbus TCP protocol in TLS 1.2 for secure, private operation and defense against cyber-attacks in mission-critical applications. When used with Cypherbridge uSSL SDK, uMODBUS implements X.509 mutual authentication, role identification, AuthN, and AuthZ with a role-to-rights database. The toolkit is integrated with the Cypherbridge SDKPac framework, allowing deployment across various platforms, operating systems, TCP/IP stacks, and toolchains.
