7.1 Application
You can match some of the activities of the system program to your
own particular requirements by selecting settings in DX 0 that differ
from the defaults (marked in the following table by "D").
The system program defaults (D) are set automatically at each COLD
RESTART. Following this, DX 0 is evaluated. If you do not program
and load a DX 0 block, the defaults remain valid; otherwise, the
settings you have made in DX 0 become valid.
You program DX 0 just as with other data blocks by assigning values
using STEP 5 statements, (see Sections 7.2 to 7.4.1) or (with PG
system software S5-DOS from Version 3.0 onwards) entering the
values as parameters in a special screen form on your PG (see
Section 7.4.2).
Note
Entries or changes to DX 0 only become effective when you perform
a COLD RESTART.
If a
modified DX 0 comes into effect during a COLD RESTART,
any parameters you do
not modify are retained.
