FP_CLEAR_UNIT_ERROR

Clear error/warning of units

This FP instruction clears an error or warning in the unit attached to the slot number specified by s1_Slot if the trigger EN is TRUE. The instruction can be used for the following types of units: High-speed counter unit, positioning unit, pulse output unit, motion control unit, serial communication unit.

Parameters

Input

s1_Slot (WORD, INT, UINT): Slot number

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if the area specified using the index modifier exceeds the limit.
if the slot number is outside the permissible range

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

if the area specified using the index modifier exceeds the limit.
if the slot number is outside the permissible range

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
		bClearError: BOOL:=FALSE;
		iSlot: INT:=1;
	END_VAR

POU body

When the variable bClearError is set to TRUE, the instruction is carried out.
