- sjg007 7y agomanual ack udp? What?
- Gibbon1 7y agoI think it's a systems issue not really a software one. You need some sort of gap between the control unit (which can kill people) and the monitoring system which shouldn't be able to. Would be perfectly reasonable to pass monitoring data from the control unit via a tx only channel to a networked monitoring device. For instance using a digital opto-coupler to galvanically isolate the two units.
- ryacko 7y agoI believe it would be cheaper, and thus more likely to be adopted if tx only was implemented in software, such as a iptable rule. Hardware tx only would only make sense if you avoid side channels as well.
