FP_DIRECT_OUTPUT

Direct output refresh

This FP instruction sets the direct output memory specified by Slot and Offset independently from any IO refresh. Additionally, it sets also the corresponding output flag or flags.

Parameters

Input

Slot (WORD, INT, UINT): Slot number
Offset (WORD, INT, UINT): Offset
Value (BOOL, WORD, DWORD): Value of the direct output

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 the area specified using the index modifier exceeds the limit.

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
		bTestBool: BOOL:=FALSE;
		bTestWord: BOOL:=FALSE;
		bTestDWord: BOOL:=FALSE;
		iSlot1: INT:=1;
		iOffset21: INT:=21;
	END_VAR
