Operands:
S
: Source GRAY CODE
D
: Destination address for the converted BIN result
Description:
1. The GRAY CODE value in
S
is converted to an equivalent BIN value and the result is stored in
the device specified by
D
.
2. This instruction can be used to read the value from an absolute position type encoder (a gray
code encoder) which is connected to the ELC inputs. Convert the value to a BIN value and
store it in the specified register.
3. If the source is inputs X20~X37, it can speed up the input response time by using the REFF
instruction or D1020 (adjust input response time).
4. The range of
S
that can be converted to the GRAY CODE is as follows:
16-bit instruction: 0~32,767
32-bit instruction: 0~2,147,483,647
5. If the GRAY CODE value is outside the range shown above, it is an “Operation Error”.
Program Example:
When X0=ON, the GRAY CODE value in the absolute position type encoder connected to X20~X37
inputs is converted to BIN value and stored in D10.
