FX Series Programmable Controlers Applied Instructions 5
5-101
5.9.6 VRRD (FNC 85)
Operation:
The identified volume (S) on the FX-8AV is read as
an analo
input. The analo
data is in an 8 bit
format, i.e. values from 0 to 255 are readable. The
read data is stored at the destination device
identified under operand D.
5.9.7 VRSD (FNC 86)
Operation:
The identified volume (S) on the FX-8AV is read as
a rotar
switch with 11 set positions (0 to 10). The
position data is stored at device D as an inte
er
from the ran
e 0 to 10.

Note:
The FX-8AV volume ‘inputs’ are able to be read in two formats, a) as an analo
value and b)
as an 11 (0 to 10) position rotar
switch. The second use is described in the VRSC instruction
(FNC 86).
