FP_DIRECT_OUT

Write direct output flag

This instruction writes the value of an output flag (Y) using a direct execution command. The Output_Y will be written asynchronously within the current PLC cycle.

Input

Value FP0H, FP-XH: (BOOL); FP7: (BOOL, WORD, DWORD): Value written directly to Output_Y

Output

Output_Y FP0H, FP-XH: (BOOL); FP7: (BOOL, WORD, DWORD)

Global variable with FP address or explicit user address to be written directly.

FP0H, FP-XH only: Valid range for FP address is Y0–Y109F to which a real output pin is assigned. Otherwise the PLC goes into operation error.

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.

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
		bWriteOutput: BOOL:=FALSE;
	END_VAR

LD body

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