Purpose
Ladder Symbol
Variations
/UL(433) divides the unsigned binary values in Dd and Dd+1 by those in Dr
and Dr+1 and outputs the quotient to R, R+1 and the remainder to R+2, and
R+3.

Error Flag ER
Equals Flag =
Negative Flag N
When the content of Dr, Dr+1 is 0, the Error Flag will turn ON.
If as a result of the division, the content of R, R+1, is 0000 hex, the Equals
Flag will turn ON.
If as a result of the division, the content of the leftmost bit of R+1 is 1, the Neg-
ative Flag will turn ON.
When CIO 0.01 is ON in the following example, D201 and D200 will be
divided by D211 and D210 as 8-digit unsigned hexadecimal values, the quo-
tient will be output to D221 and D220, and the remainder will be output to
D223 and D222.
