Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
Error

The data of is other than 0 to 32767 when the GBIN instruction is
S
4100
executed.
The data of is other than 0 to 2147483647 when the DGBIN
S

instruction is executed.
Program Example
(1) The following program converts the Gray code data at D100 when X10 is ON to BIN data, and stores the result at D200.
[Ladder Mode]
(2) The following program converts the Gray code data at D10 and D11 to BIN data when X1C is ON, and stores the result
at D0 and D1.
