The pulse widths of the signal at the input IN2 / IN5 (PULSE) are measured with a
programmabletimebase(f
ref
,seefigure“Counter access”).
The modules differ in having different counting directions:
Mode 21: Upcounter.
Mode 22: Downcounter
The measuring process is enabled with a HIGH level at input IN3 / IN6 (GATE).
The measuring process starts with a HIGH-LOW edge at input IN2 / IN5 (PULSE)
and ends with the LOW-HIGH edge.
A LOW-HIGH edge of the measured signal stores the pulse width with the unit
1/f
ref
. This result can be found and read out in the data output range until the next
result appears.
During the counting process, a LOW level must be applied to input IN1 / IN4 (RES).
A HIGH level deletes the counter.
Output OUT0 / OUT1 has no function.

 Note!
The measuring process is terminated only if a HIGH level is
applied at input IN3 / IN6 (GATE) for the complete duration of the
measuring process.
