7: accept preset actual value, coil CI..EN
8: reset coil CI..RE
9: contact (make contact) CI..OF upper setpoint value reached,
exceeded
10: contact (make contact) CI..FB lower setpoint value reached,

• Range A:
– The counter counts upwards.
– The value leaves the lower threshold value and reaches the
upper value.
• Range B:
– The count direction changes to a downward count.
– The contacts switch in accordance with the actual value.
• Range C:
– The enable signal is set to 0. The actual value becomes 0.
• Range D:
– The rising edge on the accept preset value coil sets the actual
value to the preset value.
• Range E:
– The reset pulse sets the actual value to zero.
• Range F:
– The actual value goes outside the value range of the counter.
– The contacts become active according to the direction of the
values (positive or negative).
Comparators
Comparator function blocks allow you to compare constants
and variables with one another.
The following comparisons are possible:
