Carries out sequential integration on input data, calculates the average value at each averaging time, and
outputs the result.
Integrates the value obtained by multiplying the input data by a proportional constant, and outputs the result.
Outputs a pulse at the set time interval.
Adds dead band compensation to the input and outputs the result.
Detects rise of pulse and counts the number of pulses.
Integrates the input signal and converts it to number of pulses for output.
Decodes 2-bit pure binary input and outputs it to 4 terminals.
Calculates moving average of input data and outputs the result.
Holds the input value according to sample signal (0/1) and continues the output.
Usable for dead time compensation control etc. Data sampling can be done in 1 sec or 1 min units.
Outputs ON-OFF signal with hysteresis versus the input.
Compares the input and set value and outputs the judgement result.
Performs output processing in time proportional PID control.
Carries out AND, OR, NOT, EOR and a combination of these logical operations.
Carries out a combination of addition, subtraction, multiplication and division.
Carries out temperature and pressure compensation through use of differential pressure, compensated
pressure, proper temperature.
Carries out segmented-line approximation with 15-segmented-line function.
Time schedule control by step or polygonal line approximation with 7 segments.
RS flip-flop.
Adds the change of input at each basic cycle to the previous integrated value.
judgement on large/small.
Selects input or output via a switch function. Analog hold circuit also provided.
Outputs on-delay, off-delay timer signal via start of input signal according to timer setting.
Carries out absolute value processing on input and outputs the result. Also judges the sigh (Positive, negative)
of input value and outputs the result.
Extracts square root of input value and outputs the result. Low input cutoff function equipped.
Carries out lead/lag operation on the input and outputs the results. Used as analog filter function and for various
compensations.
Limits the input within the range of high/low limit settings, and outputs the result. Also outputs high/low limit
alarm signal.
Outputs signal which changes in ramp from toward target value at the set full scale time.
There are two of these wafers…in minute unit and hour unit.
Compares two input values, and provides HIGH output (Large one), LOW output (Smaller one), and result of

Functional outline
(
The wafer is a functional unit software package contain-
ing control and computation functions needed for meas-
urement and control. Combination of these wafers each
having its own particular function enables composing a
flexible system applicable to a wide range of control…
from basic PID control up to complex advanced control.
The PNC2 can accommodate up to 24/48 wafers.
The following kinds of wafers are prepared to allow selec-
tion according to the control purpose.
Various internal terminals are provided for external analog
input/output, digital input/output and wafer connection.
Various parameters used in computation and control can
be freely defined.
32 constants at 24 wafers
48 constants at 48 wafers
For control .......... PID control, ratio control, program
For computation .. Various computations possible by
control, gain scheduler, PID para-
meter setting
