HSC Interrupt POU
This is the name of the Program Organizational Unit (POU) which is executed
immediately when this HSC Interrupt occurs. You can choose any
pre-programmed POU from the drop-down list.
Auto Start (HSC0.AS)
The Auto Start is configured with the programming device and stored as part of
the user program. The auto start bit defines if the HSC interrupt function
automatically starts whenever the controller enters any run or test mode.
Mask for IV (HSC0.MV)
The MV (Overflow Mask) control bit is used to enable (allow) or disable (not
allow) an overflow interrupt from occurring. If this bit is clear (0), and an
overflow reached condition is detected by the HSC, the HSC user interrupt is
not executed.
This bit is controlled by the user program and retains its value through a power
cycle. It is up to the user program to set and clear this bit.
Mask for IN (HSC0.MN)
The MN (Underflow Mask) control bit is used to enable (allow) or disable (not
allow) a underflow interrupt from occurring. If this bit is clear (0), and a
Underflow Reached condition is detected by the HSC, the HSC user interrupt is
not executed.
This bit is controlled by the user program and retains its value through a power
cycle. It is up to the user program to set and clear this bit.
