        • migration of HV control from VME control via caennet (MDC) &arr; main IOC &arr; separate HV control PC (maybe lxhadesdaq01?)


      HADES MDC HV trip sequencer
      • migration to linux box away from VME
        • network based control sequences
        • introduction of Hardware Limits
      • improving existing trip sequencer by stepping HV behaviour
        • documentation missing

      HADES / HADCON: triple redundancy 1-wire ADC readout
      • in an noisy environment, the 1-wire ADC readout (via OwAdc1) used at several places suffers from spikes
        • w/ a typical scan rate of 0.1-1 Hz a falls signal may be persistent for almost 10 seconds, provoking false interlock signals
        • e.g. differential pressure measurement MDC
        • absolute pressure measurement
      • implement to HADCON 1-wire control command OWAD a feature, to perform a triple read of a channel, and remove a possible spike
