7.5 Input Frequency Measurement Function

7.5.1 Overview

● The measurement function is to measure the changes in the count values of the high-speed
counter for external outputs and to output them as frequencies.
● Measuring results are stored in unit memories (UM). They can be read by user programs if
necessary.
● As the measurement function is enabled automatically when the high-speed counter for
external inputs is allocated, the configuration for using the input frequency measurement
function is not required.

7.5.2 Reading Measurement Value

Measurement values can be read from the unit memory area.
