Wiring Digital Inputs
 Inputs may be wired as either pnp (positive logic) or npn (negative logic).
 Input 36 can function as a high-speed counter, frequency measurer, or general purpose digital input (set in software).
 Input 37 can function either as a counter reset input or general purpose digital input (set in software).
 For correct operation of the digital inputs, connect the n/p pin according to the following figures.
 For information on connecting RG pins, refer to Connecting RG Pins.
pnp (positive logic) inputs 32-39
pnp (positive logic) inputs 40-47
