4.5 Counter
easy provides 16 up/down counters C1 to C16 for use as required. The counter
relays allow you to count events. You can define an upper threshold value as a
comparison value. The contact will switch according to the actual value.
4.5.0.1 High-speed counters, frequency counters up to 1 kHz counter frequency.
easy-DA and easy-DC feature four high-speed counters C13 to C16. The
function is defined by the mode selected. The counter input is connected
directly to a digital input. The high-speed digital inputs are I1 to I4. Possible
applications include the counting of components, lengths, events and
frequency measurement.
