Converts the BCD data (0 to 99999999) in the device specified for to the BIN data, and stores
the result to the device specified for .

In the following case, an operation error occurs, the error flag (SM0) is turned ON, and the
corresponding error code is stored to SD0.
• Values other than 0 to 9 are specified for each digit of . (Error code: 4100)
[When using the QCPU]
When the QCPU is used, the error above can be suppressed by turning ON SM722.
However, the instruction is not executed regardless of whether SM722 is turned ON or OFF
if the specified value is out of the available range.
For the BINP and DBINP instruction, the next operation will not be performed until the
command (executing condition) is turned from OFF to ON regardless of the presence or
absence of an error.
Program E xam pl e
(1) In the following program, the BCD data in X10 to X1B are converted to the BIN data when X8
turns ON, and the result is stored to Var_D8.
