FREQUENCY INPUT:
This parameter (available only for AI4-7) specifies that the input signal is a pulse train whose
frequency is to be measured. The value of the input becomes (SPAN x FREQUENCY) + ZERO.

PULSE COUNT:
When the input is configured for a frequency input this value represents the total number of pulses
applied to the analog input terminals. The count value automatically resets to 0.0 when it reaches
10,000,000.

TAG NAME:
A user assigned name for the AI can be loaded into this parameter.

ENGINEERING UNITS:
The units of measure the AI represents can be loaded into this parameter.
