• Range C: the counter is enabled. After a frequency above the setpoint was measured for the first time,
contact C15 (C16) switches.
• Range D: The reset coil resets the actual value to zero.
Example: frequency counter
Frequency counters with different switch points.
The frequency measured at input I3 is to be classified in different value
ranges. The analog value comparator is used as an additional comparison
option.
The counter is enabled via the marker N3. The value 900 or higher is
detected by frequency counter C15 as the upper limit value. This triggers the
coil of marker N4.
If the frequency is higher than 600 Hz, analog value comparator A1 indicates
this and triggers marker N5.
If the frequency is higher than 400 Hz, analog value comparator A2 indicates
this and triggers marker N6.
4.6.2 High-speed counters
You can use the high-speed counters to count high frequency signals reliably.
easy provides two high-speed up/down counters C13 and C14 for use as
required. The high-speed counter inputs are permanently connected to the
digital inputs I1 and I2. This counter relay allows you to count events
independently of the cycle time.
The high-speed counters allow you to enter an upper threshold value as a
comparison value. The C13 and C14 high-speed counters are not dependent
on the cycle time.
