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

Program Example
(1) In the following program, the BCD value in Var_D7 is multiplied by the BCD value in Var_D8
when X20 turns ON, and the result is stored to Var_D0.
