Digital Counter Scheme Logic - GE T60 Instruction Manual

5 SETTINGS
• 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
and
CNT1 SET TO PRESET
2. When the counter is running and the
changing from 1 to 0 while the counter is running has no effect on the count).
PRESET
3. When a reset or reset/freeze command is sent to the counter and the
1 (when a reset or reset/freeze command is sent to the counter and 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
• 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.
