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.
Program example
• The following program multiplies the BCD data 67347125 and 573682, stores the result from D502 to D505, and at the
same time outputs the upper 8 digits to Y30 to Y4F.
• The following program divides the BCD data from X20 to X3F by the BCD data at D8 and D9 when X0B goes ON, and
stores the result from D765 to D768.
