EnableInterrupt
With this function, the physical interrupt which was deactivated beforehand
can now be re-enabled as an active interrupt.

Parameterization
The parameterization and prioritization of the interrupt occurs in the “PLC
and Task Configuration” of the CODESYS (activate the “Resources” tab and
call up the “Task configuration l system events” folder). Each interrupt can
be assigned with a POU here.
Example of interrupt processing
A “Basic” task contains a POU “PLC_PRG”. A further POU “Fastprog”
should be processed if an L ￫ H rising edge on the input I0.4 generates an
interrupt.
▶ Create the POUs „FAST_PRG“ as shown in Figure 70.
