Processing details
Conducts the input data (PV) Upper/
lower limit check, input limiter
processing, engineering value
conversion, and digital filter processing.
Calculates the MV (0 to 100%) from the
input data (MV), processes the upper
and lower limit and Change rate limiter
processing, and conducts output on time
conversion.
Performs change rate, upper/lower
limiter processing and output on time
conversion from the input data (MV).
Reads the MV of the loop tag memory
and performs output conversion and
alarm clear processing.
Changes the ON/OFF rate within a
given cycle in proportion to the input
data (0 to 100%) and outputs the result.
