Behavior of the Digital Inputs

Digital input of the 1Count5V
The DI digital input can be operated with 24 V sensors (P switch and series mode).
In the case of the input and HW gate functions, the level of the digital input can be inverted
by means of "Function DI = Hardware gate" setting with the parameter "Input signal
hardware gate" .
The STS_DI feedback bit indicates the level of the digital input.
