3.2.30 DIV_ - Division
DIV_ function blocks perform simple arithmetic division.
The output will be the quotient of the two configured
inputs N/D. The output will be limited to the maximum
real number and, if the divisor is 0.0, the output will go to
the maximum real number with the sign determined by the
numerator. If the numerator is 0.0, the output will be 0.0.
Any unconfigured inputs will be set equal to 1.0.

3.2.31 DNC_ - Divide by N Counter
DNC_ function blocks provide a single output pulse for a
pre-selected number of input pulses. The output will go
high (1) with a positive transition of the input P, edge
triggered, and will return to a low (0) output on the
succeeding positive transition.

POWER UP - During a hot or a warm start, with PU LAST
set to YES, the block will retain the last count and continue at
the last input/output states. If set to NO, during a warm or a
cold start, the output and count will be initialized to 0.
