FP_COPY

Copy data to memory block

This FP instruction copies the data or equivalent constant specified by s to the memory block specified by d1_Start and d2_End if the trigger EN is TRUE.

Parameters

Input

s (INT, UINT, WORD, DINT, UDINT, DWORD, REAL, DATE, TOD, DT): Source value to be copied

Output

d1_Start (INT, UINT, WORD, DINT, UDINT, DWORD, REAL, DATE, TOD, DT): Starting address of the destination data area
d2_End (INT, UINT, WORD, DINT, UDINT, DWORD, REAL, DATE, TOD, DT): Ending address of the destination data area

Remarks

The input and output variables have to be of the same data type.
The operands d1_Start and d2_End should be:
- in the same memory area, e.g. DT, WR, FL, LD ...
- d1_Start £ d2_End

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if the area specified using the index modifier exceeds the limit.

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if d1_Start > d2_End

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		bStart: BOOL:=FALSE;
			(*activates the function*)
		aiDataField: ARRAY [0..6] OF INT:=[1,3,5,7,9,11,13];
			(*result after a 0->1 leading
edge from start:
[1,3,5,11,11,11,13]*)
	END_VAR

POU body

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