2 How to use the hardware interfaces
This chapter will explain how to use the hardware IO interfaces and how to
wire your equipment to the Barionet.
When following these instructions, then please make always sure that your
Barionet is not powered up during wiring/connecting your equipment to the
Barionet !
Please make also sure you not overload (not too high voltage or load) the
Barionet´s hardware interfaces (like inputs, outputs or relays).
2.1 How to use the digital inputs ?
A digital input of the Barionet knows only two states :
ON (1)
or
OFF (0)
On the Barionet100 the input polarity can be changed in the configuration
setup (under “IO”).
There are three different ways to use a digital input :
A – connecting input to ground directly
B – using with a (manual) button/switch
C – using with a sensor (or automatic switch)
