F14_PGRD

Program read from IC card

When the execution criterion of F14_PGRD is turned ON, the execution proceeds until the END. The program subsequently switches to the program specified by s.

Parameters

Input

s (ARRAY [0..5] OF WORD): starting address of area storing program

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
		start: BOOL:=FALSE;
			(*activates the function*)
		dummy_array: ARRAY [0..5] OF WORD:=[6(0)];
			(*contains the file
name in HEX_ASCII format*)
	END_VAR

POU body

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

The instruction reads the program Prog1 from the IC card and executes it.
