Hello,
Please could someone conclude this hidden programming technic!
In robot cell is defined DO from 1 to 512, but in two program
is checked value of non-existent DO[11002] and
on the end of first program set ON DO[11012] and
in second set ON DO[11014] both non-existent.
Any idea?
Should I expand DO to 
Hi
Fmiroslav,
Maybe you don't need it.
it could be an example looks in your I/O mapping if that signal is used.
If this is correct you need to add an extra rack to be able to manipulate that signal. (In your Digital I/O screen)
sometimes some programmers add either signal to be replaced on-site.
Regards!
Hi,
THX WEBER.
Maybe this line is abandoned. I find one more DO check for non-defined segment
comment is XX 
Possible on this Robot all G1_ program are abandoned and obsolete
Thanks!
Hi,
maybe the PMC function is or was used.
Accessing the (internal)PMC-IO's is done via the "10000++ " ID's.
from PMC pdf:
DO[10001-10136] K0-16
DO[10137-10160] K900-902
DO[11001-23000] R0-1499
GO[10001-11500] D0-2999
Memory for K, R, D of PMC is assigned to DO, GO of Robot.
This assignment is for compatibility with conventional models.
The assignment for K, R, D is available only for these assignment patterns. Any
other assignment pattern (Ex. Assign K0 to DO[1-8]) is not available.
best regards
PnsStarter
