Comparison instructions

Compares the 32-bit data or 32-bit equivalent constant specified by s1 with one specified by s2 if

the trigger EN is in the ON-state. The compare operation result is stored in special internal relays

R9009, R900A to R900C.

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

comparison instructions. Please refer also to Advantages of the IEC instructions in the online help.

# turns ON or OFF depending on the conditions

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.

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

In this example the function has been programmed in ladder diagram (LD) and structured text

(ST).The same POU header is used for all programming languages.

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