C ]− Output
Function
When the input is ON, the unsigned data of A and B are multiplied, and the result is stored in
double-length register C+1
⋅
C. The data range of A and B is 0 to 65535 (unsigned 16-bit data)

Example
When R010 is ON, the data of D0050 is multiplied by the data of RW05, and the result is
stored in double-length register D0101⋅D0100 (upper 16-bit in D0101 and lower 16-bit in
D0100).
If the data of D0050 is 52500 and the data of RW05 is 30, the result 1575000 is stored in
D0101⋅D0100.
D0050 52500
×
D0101⋅D0100 1575000
RW05 30
Note
• This instruction handles the register data as unsigned integer.
