Product Protection for Use in
Environments Subject to Water or Oil
The panel surface has a protective
structure so that the internal circuits will
not be adversely affected if drops of water
penetrate the gaps between the keys. If,
however, there is a possibility of water or
oil being present on the operator's hands,
mount the optional Soft Cover.
The Soft Cover ensures protection
equivalent to IP54. Do not, however, use
the H7BX in locations where it would come
into direct contact with oil.
Note: Depending on the operating environment,
the condition of resin parts may
deteriorate, and may shrink or harden.
Therefore, it is recommended that resin
parts are replaced regularly.

Multifunction Counter H7BX 11
■Explanation of Functions
Settings marked with a star can be performed with the DIP switch.
•Input Mode (cntm) ★
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. 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 13.)
•Dual Count Calculating Mode (calm)
When the H7BX 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 (outm) ★
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. 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 14.)
•One-shot Output Time (otim) ★
Set the one-shot output time (0.01 to 99.99 s) for the control
output. A 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. Use the
operation keys if other settings are required.
•One-shot Output 2 Time (otm2) ★
When the H7BX 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). A 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. Use the
operation keys if other settings are required.
•One-shot Output 1 Time (otm1)
When the H7BX using as a 2-stage counter, set the one-shot
output time (0.01 to 99.99 s) for control output (OUT1). A 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, hold is displayed,
and outputs are held.
•Counting Speed (cnts)★
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 (iflt) ★
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 (dp)
Decide the decimal point position for the present value, CP1/
CP2 present values, set values (SV1, SV2), total count value,
dual count value and dual count set value.
•Prescale Value (pscl)
Pulses input to the counter are converted according to the
specified prescale value.
Setting range: 0.001 to 99.999
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 (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. For 2-wire sensors, set the format to
NPN input. The same format setting applies to all external inputs.
For information on input connections, refer to page 6.
•Display Color (colr)
Set the color used for the present value.
Note: When the H7BX using as a 2-stage counter, this is the status of output 2.
•Key Protect Level (kypt)
Set the key protect level.
For details, refer to Key Protect Level on page 24.
Output OFF (See note.) Output ON (See note.)

Multifunction Counter H7BX 17
●Total and Preset Counter Operation
The H7BX has a total counter separate from the 1-stage preset counter for counting the total accumulated value.
●Batch Counter Operation
The H7BX 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 while the batch counter reset input is on.
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.
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.
●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.
Note 1. Counting is not possible for CP1 while the reset 1 input is ON. CP2 is not affected. The dual count value will be calculated based on a CP1 present value of 0.
2. Counting is not possible for CP2 while the reset 2 input is ON. CP1 is not 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.
The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999.
If a present value exceeds 999,999, FFFFFF will be displayed to indicate an overflow, and all counting will stop.
•The total counter continues to count the total
accumulated value when the present value is reset
using reset/reset 1 input (Reset Key).
•The total count value is reset when the total 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 counter is −99,999
to 999,999. The total 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 reset input
turns ON.
•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.
•The operation after count completion for the dual
counter value is determined by the output 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
the outputs turn OFF. At this time, counting is not
possible for CP1 or CP2 inputs.
