Example:
M3 = ON when K100 > C30's current value
M4 = ON when K100 <= C30's current value <= K200
M5 = ON when C30's current value > K200
M3, M4, or M5 switches to ON when X0 = ON.
The ZCP instruction is not executed when X0 switches from ON to
OFF, and M3 to M5 remain in the state prior to X0 = OFF. Use the
RST or ZRST instruction to clear the comparison result of M3 to M5.

EZCP: Binary oating-point range comparison
◆
Overview
The EZCP instruction compares a binary oating-point variable range with a oating-point variable. The
comparison result is output to three variables from head address D.

Function
A binary oating-point variable range is compared with a oating-point variable. The comparison result is
output to three variables from head address D.
S1 is the lower limit of a binary oating-point variable range.
S2 is the upper limit of a binary oating-point variable range.
S is the binary oating-point variable to be compared.
