Counter Mode
Select a counter mode.
Linear
Performs count up or count down one time. The count operation ends when the Current Counter Value reaches either the minimum or maximum value. To start counting again, clear the Current Counter Value with the system variable (#L_ExIOCntInCtrl).
Ring
Repeatedly runs the count operation. When the counter reaches the maximum or minimum value in the counting range, the counter is reset to either the minimum or maximum value then continues counting.
Sampling
Pulse count and signal frequency within the Time Base period is stored in the Current Counter Value. When the period set in the Time Base elapses, the Current Counter Value is updated.
Counter Operation
Select the counter operation.
Preload Value
Enter the value you want to set as the current value for counter. Select when [Counter Mode] is set to [Ring] or [Linear].
Count Range
