  From time-to-time, microcontroller- and FPGA-based LLRF electronics devices need maintenance of firmware and configuration data. The system described here allows this and also long term monitoring of functionality and performance. Both requirements cover measuring devices that operate under a common operating system as well as modules only addressable by means of GPIOs or their programming interface. For large accelerator systems like in the FAIR project, a Web-based remotely controlled system was designed in close collaboration with two industrial partners. To cover the requirements of the extremely different types of participating modules while remaining flexible for future extensions, the system was designed with a maximum of modularity and a strong focus on high reliability and safety. This contribution describes the global structure and the actual status of the RF Maintenance and Diagnostics System. Several types of measuring equipment and LLRF modules such as a phase control loop system and an IF signal pre-processing system have been integrated.
