Operation error

• 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 details

When values other than 0 to 9 are specified to any digits of (S).

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 designated value is out of

the available range.

For the BINP/DBINP instruction, the next operation will not be performed until the command (execution condition) is turned

from OFF to ON regardless of the presence/absence of an error.

Program example

• The following program converts the BCD data at X10 to X1B to BIN when X8 is ON, and stores it at D8.

in other purposes.

Programmable Controller input module

[Ladder Mode]

• The following program converts the BCD data at X10 to X37 to BIN when X8 is ON, and stores it at D0 and D1. (Addition of

the BIN data converted from BCD at X20 to X37 and the BIN data converted from BCD at X10 to X1F)

[Ladder Mode]

If the data set at X10 to X37 is a BCD value which exceeds 2147483647, the value at D0 and D1 will be a negative value,

because it exceeds the range of numerical values that can be handled by a 32-bit device.
