Operands:
S: Source device D: Operation result (BIN value)
Explanations:
1. GBIN instruction converts the Gray Code in S to BIN value and stores the converted result in
specified register D.
2. This instruction can be used to read the value from an absolute position type encoder
(generally a Gray Code encoder) which is connected to the PLC inputs. The Gray code is
converted to BIN value and stored in the specified register.
3. Available range of S:
16-bit instruction ：0~32,767
32-bit instruction ：0~2,147,483,647
4. If operand S exceeds the available range, operation error occurs and the instruction is
disabled.
5. If operands S and D use device F, only 16-bit instruction is applicable.
Program Example:
When X20 = ON, the Gray Code value in the absolute position type encoder connected to X0~X17
inputs is converted to BIN value and stored in D10.
