▪ R
ange of Ring counter: user defined min. value ~ user defined max. value
▪ Counter display: in case of using ring counter, user defined max. value is not displayed.
1) During increasing count
■ Even if count value exceeds user-defined maximum value during increasing count,
Carry only occurs and count does not stop differently to Linear Count.
2) During decreasing count
■ Even if count value exceeds user-defined minimum value during decreasing count,
Borrow only occurs and count does not stop differently to Linear Count.
3) Operation when setting Ring Count based on present count value (during increasing
count)
■ If present count value exceeds user-defined range when setting Ring Count
- Error (code no. 27) is occurred and it operates linear counter.
■ If present count value is within user-defined range when setting Ring Count
- Present count value starts to increase up to the user-defined maximum value and
down to the user-defined minimum value and keeps counting after Carry occurs.
- Not the maximum but the minimum value only is displayed with count kept on as
shown below.
