Arithmetic instructions

Multiplies the 32-bit data or 32-bit equivalent constant specified by s1 and the one specified by s2 if

the trigger EN is in the ON-state. The result is stored in d[0], d[1] (64-bit area). All 32-bit values are

treated as double integer values.

This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which

is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the

"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears

under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming

area to open the list of recently used elements.

Instead of using this FP instruction, we recommend using the related IEC instruction MUL (see

page 63). Please refer also to Advantages of the IEC instructions in the online help.

ARRAY [0..1] of

The variables s1, s2 and d have to be of the same data type.

In this example, the same POU header is used for all programming languages. For an example

using IL (instruction list), please refer to the online help.

All input and output variables used for programming this function have been declared in the POU

When the variable start is set to TRUE, the function is carried out.

Access to the result is possible with output_value[0] and output_value[1].
