This group function code is used when using AI as DI, when AI used as DI, and input
voltage of AI is greater than 7V, AI terminal status will be high level, when input voltage of
AI is lower than 3V, AI terminal status will be low level. For between 3V~ 7V hysteresis
E3.10 is to determine that when the AI is used as DI, AI is made valid by means of the high
level state, or the low level of valid states. As for AI as DI feature set, same as the ordinary
DI Settings, please refer to the F1 group setting instructions related DI.
Below figure is AI input voltage taken as an example, explains the relationship between
input voltage of AI and the corresponding state of DI:
