FP_INTERRUPT_CLEAR_REQUESTS

Clear interrupt programs for one unit

This FP instruction clears interrupt programs for the unit installed in the slot specified by d_Slot according to the data specified by s_Control.

Parameters

Input

d_Slot (WORD, INT, UINT)

Slot number: 1–16

s_Control (WORD)

Control word to clear the interrupt number of the unit installed in the specified slot: 16#0–FF

(1) Higher 8 bits: fixed at 1
(2) 0: Interrupt cleared
(3) 1: Interrupt not cleared

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

Global variables

In the global variable list you define variables that can be accessed by all POUs in the project.

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.
