5.9.6

VRRD (FNC 85)

Operation:

The identified volume (S) on the FX-8AV is read as
an analog input. The analog 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 rotary switch with 11 set positions (0 to 10). The
position data is stored at device D as an integer
from the range 0 to 10.

Note:

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