Parameters for interrupt
processing
You can use the table below to find the correct parameter for your
interrupt processing and you can program DX 0 with this parameter.
Depending on the parameter you select, some (or all) interrupts will
be effective at block boundaries and other (or all) interrupts will be
effective at operation boundaries, according to the shading in the
symbols.
Note
If you enable interrupt processing at operation boundaries, the
operations "TNB" "TNW" may also be interrupted. This also applies
to a few of the special function organization blocks, standard
function blocks and controller function blocks.
1)
The PG software for generating DX0 uses the "old" parameters. If you generate a DX0 with new parameters using
STEP 5 and want to display it on the PG, an error message is displayed.
