5.15.1

GRY (FNC 170)

Operation:

The binary integer value in S is converted to the
GRAY CODE equivalent and stored at D.

Points to Note:

The nature of gray code numbers allows numeric values to be quickly output without the need
for a strobing signal. For example, if the source data is continually incremented, the new output
data can be set each program scan.

5.15.2

GBIN (FNC 171)

Operation:

The GRAY CODE value in S is converted to the
normal binary equivalent and stored at D.

Points to Note:

This instruction can be used to read the value from a gray code encoder.
If the source is set to inputs X0 to X17 it is possible to speed up the reading time by adjusting
the refresh filter with FNC 51 REFF.
