5.7 CONTROL ELEMENTS
• COUNTER 1 UNITS: Assigns a label to identify the unit of measure pertaining to the digital transitions to be counted.
The units label will appear in the corresponding actual values status.
• COUNTER 1 PRESET: Sets the count to a required preset value before counting operations begin, as in the case
where a substitute relay is to be installed in place of an in-service relay, or while the counter is running.
• COUNTER 1 COMPARE: Sets the value to which the accumulated count value is compared. Three FlexLogic™ output
operands are provided to indicate if the present value is 'more than (HI)', 'equal to (EQL)', or 'less than (LO)' the set
value.
• COUNTER 1 UP: Selects the FlexLogic™ operand for incrementing the counter. If an enabled UP input is received
when the accumulated value is at the limit of +2,147,483,647 counts, the counter will rollover to –2,147,483,648.
• COUNTER 1 DOWN: Selects the FlexLogic™ operand for decrementing the counter. If an enabled DOWN input is
received when the accumulated value is at the limit of –2,147,483,648 counts, the counter will rollover to
+2,147,483,647.
• COUNTER 1 BLOCK: Selects the FlexLogic™ operand for blocking the counting operation. All counter operands are
blocked.
• 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

2. When the counter is running and the

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
• 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.
