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).
