ABSTRACT
The article talks about the advantages of smart instruments over traditional analogue. It reveals that instruments containing firmware are not limited to measurements but also cover actuators, valves and other control equipment. It also enumerates the reasons for the usage of analogue transmitters in safety instrumented systems (SIS) which included the fact that deviation diagnostics can function even when the hazardous condition is lacking. It then details problems with nuclear SIS and the framework for smart substantiation.

    A watchdog timer is a counter that counts down with time from an initial value to zero. If your firmware ignores this tool long enough, the watchdog timer resets or interrupts the system without human intervention when the counter reaches zero. A reasonable approach to this programming chore is...
