F10_BKMV_OFFSET

Block move to a offset from source

This instruction is a modification of the F10_BKMV generated by the compiler.

The data block specified by the 16-bit starting area specified by s1_Start and 16-bit ending area specified by s2_End are copied to the block starting from the 16-bit area specified by the offset d_Offset from s1_Start if the trigger EN is in the ON-state.

Parameters

Input

s1_Start (WORD, INT, UINT): starting 16-bit area, source
s2_End (WORD, INT, UINT): ending 16-bit area, source
d_Offset (WORD, INT, UINT): offset from s1_Start, destination

Remarks

Whenever s1_Start and s2_End are in the same data area:
- d_Offset = 0: data will be recopied to the same data area.
The variables s1_Start, s2_End and d_Offset have to be of the same data type.

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
		Array1: ARRAY [0..5] OF INT:=[6(0)];
		CopyArrayInArray: BOOL:=FALSE;
	END_VAR

POU body

When the variable CopyArrayInArray changes from FALSE to TRUE, the function is carried out. It copies the data block starting at the 16-bit area specified by s1_Start and 16-bit ending area specified by s2_End to the block starting from the 16-bit area specified by the offset d_Offset from s1_Start.
