Suspend or Resume I/O Interrupt

Suspend or resume an I/O interrupt when using I/O variables.
If not using I/O variables, use SVC_REQ 32.
The function executes successfully and passes power to the right unless:

Parameter Description
SUSP Selects a suspend or resume
operation.
1 (ON)=suspend
0 (OFF)=resume
IN1 The interrupt trigger to be
suspended or resumed.
Example
In the following example, the variable Mod_Int is mapped to an I/O point on a hardware module and
is configured as an I/O interrupt to a program block. When the BOOL variable SuspOn_Off is set to
ON and A1 is set to ON, interrupts from Mod_Int are suspended until SuspOn_Off is reset.
