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.
