FX Series Programmable Controlers Applied Instructions 5
5-38
5.4.7 WSFR (FNC 36)
Operation:
The instruction copies n
2
source devices to a word
stack of len
g
th n
1
. For each addition of n
2
words, the
existin
g
data within the word stack is shifted n
2
words
to the ri
g
ht. An
y
word data movin
g
to a position
exceedin
g
the n
1
limit is diverted to an overflow area.
The word shiftin
g
operation will occur ever
y
time the
instruction is processed unless it is modified with
either the pulse suffix or a controlled interlock.
Note
: when usin
g
bit devices as source (S) and
destination (D) the Kn value must be equal.
