Function Instantaneous
value output 		Conversion
to
instantaneous
values		 This function can be used to count the number of pulses per time unit, and to convert
the values to instantaneous values (pulses x pulse weight / time unit). Any of the
following can be selected as the time unit: 1 s, 3 s, 10 s, 30 s, or 60 s. (The time unit is
set in the DM Area.)
Note 1. Errors and fluctuations will increase when the input signal pulse rate is low, so
specify a longer time unit.
Note 2. The instantaneous value is only refreshed at intervals of the time unit set.
Therefore, when the Unit is restarted, the instantaneous value will be 0000 until the time
set as the time unit has elapsed.
Note 3. When pulse weight conversion is used for accumulated values, the number of
pulses obtained by multiplying the actual number of input pulses by the pulse weight
(0.1000 to 3.2000) for one time unit is used.
Instantaneous
value scaling		 This function can be used for scaling instantaneous
values (pulses × pulse weight/time unit), i.e., setting
data with respect to a maximum value, and storing
them in the allocated words of the CIO Area.
When instantaneous value (pulses × pulse weight/
time unit) is 100% input: Can be set from 0.001
pulses/time unit to 32,000 pulses/time unit.
Maximum value for Instantaneous value scaling
(industrial units): Scaling of the above instantaneous
value (100% input) is possible from - 32,000 to
32,000 (8300 to FFFF, 0000 to 7D00 hex).
Note: When pulse weight conversion is used for
accumulated values, scaling is already performed for
each pulse, so an exponent of 10 of the industrial
unit is set in the instantaneous value (pulses ×
pulse weight per time unit) for a 100% input.		 Example 1:
To obtain a pulse input of 0 to
2,000 pulses/s for a flow of 0 to
300.0 ml/s: Time unit: 1 s
Instantaneous value 100% input:
2,000
Maximum value for instantaneous
value scaling (industrial units):
3,000
Example 2:
When pulse inputs at 0 to 2,000
pulses/s are obtained for a
flowrate of 0 to 300.0 ml/s, and
the pulse weight function is used
for totaling: There are 0.15 ml per
pulse, so the pulse weight = 0.15.
For a flowrate of 0 to 300.0 ml/s,
0 to 2,000 × 0.15 = 300 pulses/s.
Therefore, Time unit: 1 s
Instantaneous value 100% input:
300
Maximum value for instantaneous
value scaling (industrial units):
3,000
Data storage
in the CIO
Area		 The value derived from carrying out the following
processing in order of the instantaneous value
(pulses x pulse weight/time unit) is stored in four
digits hexadecimal (binary values) in the allocated
words in the CIO Area.
1) Mean value processing → 2) Instantaneous
value scaling → 3) Scaling → 4) Zero/span
adjustment → 5) Output limits
Mean value
processing
(input filter)		 Calculates the moving average for the specified number of past instantaneous values
(1 to 16), and stores that value in the CIO Area as the instantaneous value.
Instantaneous
value alarm		 Instantaneous value 4-point alarm (HH, H, L, LL), hysteresis, and ON-delay timer (0 to
60 s) are available.
Accumulated
output 		Pulse weight
conversion		 Performs scaling for a single pulse.
Use for the accumulated value when the pulse weight (weight/pulse) is a fraction (not an
exponent of 10). (See note.)
The pulse weight (0.1 to 3.2) is multiplied by the actual number of pulses input. This
number of pulses is used as the input for conversion to instantaneous values (pulses ×
pulse weight per time unit) and the input for totaling prior to stepdown.
Example: When the pulse weight from the flowmeter is 0.26 ml/pulse, the pulse weight is
set to 0.26. When one pulse (0.26 ml) is input, it is treated as a 0.26 pulse, and when two
pulses (0.52 ml) are input, they are treated as a 0.52 pulse.
The weight per pulse becomes 1 ml, so to calculate in the CPU Unit the simple (unscaled)
value in industrial units (ml) based on the accumulated value from the Pulse Input Unit
(value in words n+5 to n+8), the value can be calculated simply using 1 ml/pulse.
Note: When the accumulated value from the Pulse Input Unit in the CPU Unit is not used
(i.e., when only the instantaneous value is used), pulse weight conversion is not required.
Use instantaneousness value scaling to convert to industrial units.
Accumulated
value		 The accumulated number of pulses (0 to 9,999 pulses) for each input is stored in the
allocated words of the CIO Area. When 9,999 is exceeded, the value returns to 0 and
starts counting again.
Note: When pulse weight conversion is used, the accumulated value for the number of
pulses obtained by multiplying the actual number of input pulses by the pulse weight
(0.1000 to 3.2000) is used.
Stepdown When the accumulated value is used, this function prevents accumulated value overflow
by reducing the number of input pulses. The actual number of input pulses is multiplied by
one of four factors ( × 1, × 0.1, × 0.01, or × 0.001), and the number of input pulses
accumulated is then based on that value.
Note: This stepdown function operates only for accumulated values, and not for
instantaneous values. When the pulse weight conversion function is used, it uses for the
number of pulses obtained by multiplying the actual number of input pulses by the pulse
weight (0.1000 to 3.2000).
