Operands:

S: Source device D: Operation result (Gray code)

Explanations:

1.GRY instruction converts the BIN value in S to Gray Code and stores the converted result in specified register D.

2.Available range of S:

16-bit instruction: 0~32,767

32-bit instruction: 0~2,147,483,647

3.If operand S exceeds the available range, operation error occurs and M1067 = ON, M1068 = ON. D1067 stores the error code 0E1A (HEX)

4.If operands S and D use device F, only 16-bit instruction is applicable.

Program Example:

When X0 = ON, GRY instruction executes and converts K6513 to Gray Code. The operation result is stored in K4Y20, i.e. Y20 ~ Y37.
