  The real-time control system of RFX-mod nuclear fusion experiment has been in operation since 2004 and has been used to control the plasma position and the MagnetoHydroDinamic (MHD) modes. Over time new and more computing demanding control algorithm shave been developed and the system has been pushed to its limits. Therefore a complete re-design has been carried out in 2012. The new system adopts radically different solutions in Hardware, Operating System and Software management. The VME PowerPc CPUs communicating over Ethernet used in the former system have been replaced by a single multicore server. The VxWorks Operating System , previously used in the VME CPUs has now been replaced by Linux MRG, that proved to behave very well in real-time applications. The previous framework for control and communication has been replaced by MARTe, a modern framework for real-time control gaining interest in the fusion community. Thanks to the MARTe organization, a rapid development of the control system has been possible. In particular, its intrinsic simulation ability of the framework gave us the possibility of carrying out most debugging in simulation, without affecting machine operation.
