■Characteristics
Note: 1. To meet UL listing requirements with the H7CX-A11@models, an OMRON P2CF-11-@or P3GA-11 Socket must be mounted
on the H7CX. Otherwise, H7CX-A11@models are considered to meet UL508 recognition requirements.
2. A waterproof packing is necessary to ensure IP66 waterproofing between the H7CX and installation panel.

H7CX (Counter Function)H7CX (Counter Function)
■Explanation of Functions
Input Mode ( "-3, ) (Setting possible using DIP switch.)
Set increment mode (UP), decrement mode (DOWN), or one of
the increment/decrement modes (UP/DOWN A, UP/DOWN B, or
UP/DOWN C) as the input mode. Input modes other than UP or
DOWN modes cannot be set using the DIP switch and so use the
operation keys if other modes are required. (For details on the
operation of the input modes, refer to Input Modes and Present
Value on page 18.)
Dual Count Calculating Mode (
" +, )
When using as a dual counter, select either ADD (addition) or
SUB (subtraction) as the calculation method for the dual count
value.
ADD: Dual count value = CP1 PV + CP2 PV
SUB: Dual count value = CP1 PV
- CP2 PV
Output Mode (
.43, ) (Setting possible using DIP switch.)
Set the way that control output for the present value is output. The
possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H.
Output modes other than N, F, C, or K-1 cannot be set using the
DIP switch and so use the operation keys if other modes are
required. The output modes that can be set vary with the model.
(For details on the operation of the output modes, refer to Input/
Output Mode Settings on page 19.)
One-shot Output Time (
.3(, ) (Setting possible using DIP
switch.)
Set the one-shot output time (0.01 to 99.99 s) for control output.
One-shot output can be used only when C, R, K-1, P, Q, A, or K-2
is selected as the output mode. Output times other than 0.5 s or
0.05 s cannot be set with the DIP switch and so use the operation
keys if other settings are required.
One-shot Output 2 Time (
.3, ) (Setting possible using DIP
switch.)
When using as a 2-stage counter or batch counter, set the one-
shot output time (0.01 to 99.99 s) for control output (OUT2). One-
shot output can be used only when C, R, K-1, P, Q, A, or K-2 is
selected as the output mode. Output times other than 0.5 s or
0.05 s cannot be set with the DIP switch and so use the operation
keys if other settings are required.
One-shot Output 1 Time (
.3, )
When using as a 2-stage counter, set the one-shot output time
(0.01 to 99.99 s) for control output (OUT1). One-shot output can
be used only when D, L, or H is selected as the output mode. If
the output time is set to 0.00,
'.+# is displayed, and outputs are
held. HOLD cannot be set when the output mode is K-2.
Counting Speed (
"-32 ) (Setting possible using DIP switch.)
Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2
inputs together. If contacts are used for input signals, set the
counting speed to 30 Hz. Processing to eliminate chattering is
performed for this setting.
Reset Input Signal Width (
(%+3 ) (Setting possible using DIP
switch.)
Set the reset input signal width (20 ms/1 ms) for reset/reset 1 and
total reset/reset 2 inputs together. If contacts are used for input
signals, set the counting speed to 20 ms. Processing to eliminate
chattering is performed for this setting.
Decimal Point Position (
#/ )
Decide the decimal point position for the present value, CP1/CP2
present values, set value (SV1, SV2), total count value, and dual
count set value.
Prescale Value (
/2"+ )
Pulses input to the counter are converted according to the speci-
fied prescale value. (Setting range: 0.001 to 99.999 for 6-digit
models and 0.001 to 9.999 for 4-digit models.)
Example: To display the feed distance for systems that output
25 pulses for a feed length of 0.5 m in the form
@@.@@ m:
1. Set the decimal point position to 2 decimal places.
2. Set the prescale value to 0.02 (0.5
 25).
NPN/PNP Input Mode (
(,.# )
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all exter-
nal inputs. For details on input connections, refer to Input Connec-
tion on page 36.
Display Color (
".+1 )
Set the color used for the present value.
Note: When using as a 2-stage counter, this is the status of out-
put 2.
Output Allocation (
.323 )
When using H7CX-AU@models as a 2-stage counter, the output
can be flexibly allocated to either stage 1 or 2.
Transistor output can be allocated to SV1 and contact output for
SV2 or vice verce, as in the following table.

Key Protect Level ( *7/3 )
Set the key protect level.
When the key-protect switch in set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specify-
ing the key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/OFF status
of the key-protect switch after the H7CX is mounted to the panel.
Note: Changing mode to configuration selection mode ( + 1 s min.) or function setting mode ( 3 s min.).

H7CX (Counter Function)H7CX (Counter Function)
Total and Preset Counter Operation
The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value.
Batch Counter Operation
The H7CX has a batch counter, separate from the 1-stage preset counter, for counting the number of times the count has been completed.
Note: 1. The batch count value is held at 0 during batch counter reset input.
2. If the batch count set value is 0, batch count will be performed but there will be no batch output.
3. The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digit models).
4. Once batch input has been turned ON, it will return to the ON state after power interruptions.
5. If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output
will turn ON.
6. After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the
batch count value.
• The total counter continues to count the to-
tal accumulated value when the present
value is reset using reset/reset 1 input (re-
set key).
• The total count value is reset when the to-
tal reset/reset 2 input is turned ON. If the
reset key is pressed while the total count
value is displayed, the total count value is
reset. The present value is also reset at
this time.
• The counting range of the total counteris
-
99,999 to 999,999 ( - 999 to 9,999). The to-
tal count value returns to 0 when it reaches
the full scale limit.

• The batch counter continues after count
completion.
• Batch output is held until batch counter re-
set is input.
• When the batch counter reset input is
turned ON, the batch count value is reset,
and batch output turns OFF.
• If the reset key is pressed while the batch
count value is displayed, the batch count
value is reset and batch output turns OFF.
The present value is also reset at this time.

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.
