C, counter relay
The counter relay (function relay) counts pulses that are
received at counter input C_. The count direction can be set.
You can set a lower and higher limit setpoint as comparison
values for the counter relay function block, as well as a start
value.
easySafety allows the use of up to 16 counter relays.
h
Counting is carried out cyclically. The time of a pulse must
therefore be greater than twice the cycle time.
h
Square wave count pulses are required to ensure a 1:1
mark to space ratio.
The relay counts only in RUN mode.

page 337 on Example with timing relay and counter
function block provides information on the timing relay
and counter function block.
