Background
Devices which read from memory during operation are clearly programmable components and
need to be considered according to 7.7.8. IEC 60079-11 is not clear whether a component which
only reads from memory or internal registers during initialisation – such as a digital
potentiometer – is a programmable component according to 7.7.8 or a simpler semiconductor
which can be considered according to 7.7.2.
Question
Can a digital potentiometer (or other s
