Operands:
S : Source device for BIN value D : Device for storing Gray code
Explanations:
1. If S and D are used in device F, only 16-bit instruction is applicable.
2. See the specifications of each model for their range of use.
3. This instruction converts the BIN value in the device designated in S into Gray code and stores the value in D .
4. See the ranges of S as indicated below. If S exceeds the ranges, the program will regard it as an operation
error and the instruction will not be executed. M1067 and M1068 will be On and D1067 will record the error
code 0E1A (hex).
In 16-bit instruction: 0 ~ 32,767
In 32-bit instruction: 0 ~ 2,147,483,647
Program Example:
When X0 = On, the instruction will convert constant K6,513 into Gray code and store the result in K4Y20.
