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.)
• 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).
0.5 m
• 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.

25 pulses
• 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.
Note: Incorrectly setting the prescale value will result in counting
errors. Check that the setting has been performed correctly
before using the H7BX.
• 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.
Output OFF *
Output ON *
red Red (fixed)
grn Green (fixed)
r-g Red Green
g-r Green
Red
* 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.
