13.6.1 Program in which comparison result is set to ON when power is turned ON
[ZCP (FNC 11) instruction]
DHSZ instruction outputs the comparison result only when a counting pulse is input. Even if the current value of C235
is "0", Y010 remains OFF at the time of startup.
For initializing Y010, compare the current value of C235 with K1000 and K1200 and drive Y010 by DZCPP instruction
(for general zone comparison) as pulse operation only at the time of startup.
Refer to the program example shown below.
Explanation of operation
The outputs Y010 to Y012 are as shown below:

Y010 = ON Y011 = ON Y012 = ON
