H7CX (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 (
-
999 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 models), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop.
• The operation after count
completion for the dual
counter value is determined
by the output mode.
• The CP1 present value is re-
set 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 re-
set and outputs turn OFF. At
this time, counting is not pos-
sible for CP1 or CP2 inputs.
