Symbol:
Explanation:
1. The binary value in the device specified by S is converted into the Gray code, and the
conversion result is stored in the device specified by D.
2. Only the instruction DGRY can use the 32-counter.
3. The value in the operand S should be within the available range.
The value in the operand S used in the 16-bit instruction should be within the range between 0
and 32,767.
The value in the operand S used in the 32-bit instruction should be within the range between 0
and 2,147,483,647.
Example:
When X0.0 is ON, the constant 6513 is converted into the Gray code, and the conversion result is
stored in Y1.0~Y1.15.
K6513=H1971
GRAY 6513
Additional remark:
If the value in S is less than 0, the operation error occurs, the instruction is not executed, SM0 is ON,
and the error code in SR0 is 16#2003.
