7: B A
INARY RITHMETIC
Examples: MUL
• Data Type: Word
MUL(W) S1 –
D10
I1
When input I1 is on, data of D10 is multiplied by data of D20, and the result is set to D30 and D31.
• Data Type: Integer
MUL(I) S1 –
D10
I1
• Data Type: Double Word
MUL(D) S1 –
D10
I1
D10·D11
Note: In multiplication of double word data, the lower 32-bit data of the result is set to destination device D1·D1+1.
• Data Type: Long
MUL(L) S1 –
D10
I1
D10·D11
Note: In multiplication of long data, the lower 32-bit data of the result is set to destination device D1·D1+1.
• Data Type: Float
MUL(F) S1 –
D10
I1
D10·D11
Note: Since the destination uses two word devices in the multiplication operation, data register such as D7999 cannot be used as destination device
D1. When using a bit device such as internal relay for destination, 32 internal relays are required; so internal relay such as M7961 cannot be used as
destination device D1.
