• CNT1 SET TO PRESET: Selects the FlexLogic operand used to set the count to the preset value. The counter will be
set to the preset value in the following situations:
1. When the counter is enabled and the CNT1 SET TO PRESET operand has the value 1 (when the counter is enabled
and CNT1 SET TO PRESET operand is 0, the counter will be set to 0).
2. When the counter is running and the CNT1 SET TO PRESET operand changes the state from 0 to 1 (CNT1 SET TO
PRESET changing from 1 to 0 while the counter is running has no effect on the count).
3. When a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the value
1 (when a reset or reset/freeze command is sent to the counter and the CNT1 SET TO PRESET operand has the
value 0, the counter will be set to 0).
• COUNTER 1 RESET: Selects the FlexLogic operand for setting the count to either “0” or the preset value depending
on the state of the
CNT1 SET TO PRESET operand.
• COUNTER 1 FREEZE/RESET: Selects the FlexLogic operand for capturing (freezing) the accumulated count value
into a separate register with the date and time of the operation, and resetting the count to “0”.
• COUNTER 1 FREEZE/COUNT: Selects the FlexLogic operand for capturing (freezing) the accumulated count value
into a separate register with the date and time of the operation, and continuing counting. The present accumulated
value and captured frozen value with the associated date/time stamp are available as actual values. If control power is
interrupted, the accumulated and frozen values are saved into non-volatile memory during the power down operation.
