Parameter display and parameter set for counter
relays:
In the parameter display of a counter relay you change
setpoint values and/or the preset value and the enable of the
parameter display.
Value range
The function block operates in the integer range from
–2147483648 to +2147483647.
Behaviour when value range is exceeded
The function block sets the switching contact C .. CY to the
status 1 and retains the value of the last valid operation.

Counter C counts on every rising edge at the count input.
If the value range is exceeded, the switching contact C
..CY switches to status 1 for one cycle per rising edge
detected.
