Enable Full Scale.
Set to 1 to enable a linear range from 0 to 65535 for specified input range. For a 4 to 20 mA input, a
value of 0 represents 4 mA and 65535 represents 20 mA. Set this parameter to 0 to store input readings in unit-specific
data. For example, the register data representing a 15.53 mA reading is 15530. For units of current (0 to 20 mA inputs),
values are stored as µA (micro Amps) and voltage values are stored as mV (millivolts).
Enable Rising/Falling. Use these registers to enable the universal input logic to count on a rising transition or a falling
transition. Write a one (1) to enable; write a zero (0) to disable.
High/Low Register for Counter. The low and high registers for the counter hold the 32-bit counter value. To erase the
counter, write zeroes to both registers. To preset a counter value, write that value to the appropriate register.
Hysteresis and Threshold. Threshold and hysteresis work together to establish the ON and OFF points of an analog
input. The threshold defines a trigger point or reporting threshold (ON point) for a sensor input. Setting a threshold
establishes an ON point. Hysteresis defines how far below the threshold the analog input is required to be before the input
is considered OFF. A typical hysteresis value is 10% to 20% of the unit’s range.
