16-bit command (5 STEPS)

GRY

GRYP

32-bit command

DGRY

DGRYP

 Flag signal: none

Explanation

 S: Source device D: Destination to store Gray code result

The BIN value in the specified device by S is converted to the GRAY CODE equivalent

and the converted result is stored in the area specified by D.

 The range of S that can be converted to the GRAY CODE is shown as follows:

16-bit command：0~32,767

32-bit command：0~2,147,483,647

If the BIN value is outside the range shown above, it is determined as “Operation

Error”. At this time, the command won’t be executed

Example

 When X0=On, constant K 6513 is converted to the GRAY CODE and stored in

the D0.
