A new Fault Tolerant Local Monitoring Control Board with SEU mitigation and execution redundancy commercial micro-controller — •Jose Antonio Lucio Martinez and Udo Kebschull for the CBM collaboration — IRI Goethe Universität Frankfurt, Frankfurt am Main, Germany

Since reliable program execution is necessary for the experiment integrity, new Fault Tolerant Local Monitoring Control (FTLMC) board for high energy particle detectors was developed to operate in harsh environments, taking into account the challenges that high energy physics experiments represent, a Commercial Off the Shelf (COTS) Micro Controller (MC), previously tested in accelerated particle beam, was populated in such board. The MC is the TMS570 conceived for safety and critical applications. The FTLMC provide the necessary interfaces such as SPI, I2C, CAN bus and others for detector parameter surveillance in experimental physics applications. Experimental Physics and Industrial Control System (EPICS), a commonly used SCADA for physics experiments, is ported to the MC where pre-built specific mechanisms are used to apply redundancy to programs executing with insignificant amount of CPU overhead.
