To add on to this topic, after reading about IIot and industry 4.0, what in near future is going to be is that all the parameters related to the machine is collected by smart sensors, whether its vibration,oil level, temp etc and it is fed into a network ,with the feedback loop system which trained by advanced AI module the machine itself can take prelimanary action like lubrication or notify the responsible Engineer or technician what has to be done. Basically the idea behind is that machine is very efficient than humans in information transfer.
