Each PLUS+1 ® module input pin supports one of the above functional types. For pins with multiple
functions, input configurations are user programmable using PLUS+1
Multifunction pins that are configured to be DIN are subject to the same update rates as the analog input
function for that pin. Debounce is not used, as hysteresis is built into the function. The time to recognize
a transition is dependent on the timing of the switch activation and the sample rate.
Comment
Non-damaging, non-latching; reading saturates to the low limit.
Non-damaging, non-latching; reading saturates to the high limit.
Pin configuration dependent: No pull up/ no pull down = floating
Pull up to 5 Vdc = 5 Vdc
Pull down = 0 Vdc
Pull up/ pull down = 2.5 Vdc
Programmable (see specific data sheets for ranges).
