28 Multifunction Preset Counter H7CX-A (Counter Function)
Dual Counter Operation
Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for
which output turns ON when the set value matches the added or subtracted result.
OUT1 and OUT2 turn ON and OFF simultaneously.
Note: 1. Counting is not possible for CP1 during reset 1 input. CP2 will not be affected. The dual count value will be calculated based on a CP1
present value of 0.
2. Counting is not possible for CP2 during reset 2 input. CP1 will not be affected. The dual count value will be calculated based on a CP2
present value of 0.
3. The counting range for the dual count value is
−99,999 to 999,999 (0 to 9,999 for 4-digit models). The counting ranges for the CP1 present
value and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models). If a present value exceeds 999,999 (9,999 for 4-digit mod-
els), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop.
• The operation after count com-
pletion for the dual counter
value is determined by the out-
put mode.
• The CP1 present value is reset
when reset 1 input is turned
ON and the CP2 present value
is reset when reset 2 input is
turned ON.
• If the reset key is pressed while
the dual count value, CP1
present value, or CP2 present
value is displayed, all of the
present values are reset and
outputs turn OFF. At this time,
counting is not possible for
CP1 or CP2 inputs.

Dual Count Calculating Mode = ADD
Dual count value = CP1 PV + CP2 PV
Dual Count Calculating Mode = SUB
Dual count value = CP1 PV − CP2 PV

K-2, D, L, or H is selected as the output
mode with 6-digit models.
