      @mikeyh Hi Mike,

      thanks for update. Could you please try to test one Raspberry Pi with certain SD card (i.e. OS) and check with working Monarco HAT and then switch the one failing so we can say it is Monarco HAT failure afterwards?

      Thanks for cooperation.

      Kind Regards,
      Tomas

      @apollo I understand. Just keep in mind that the Passive feature is available both at Modbus RTU and Modbus TCP.

      Kind Regards,
      Tomas

      Hi Richard,
      there are various "simplifications", using various offsets to distinguish between the four tables of data. For Holding registers, the most typical is offset of 40000, but as you already noticed, this is no standard.

      Best regards,
      Jaroslav
