NUMBER
(WARNING)
If some of them are unnec-
essary, remove them. If all
of them are necessary, as-
sign other number to pa-
rameter of them to make
them unique. (If two or more
instructions with same pa-
rameter number will never
be active simultaneously at
one time, the Ladder pro-
gram has a possibility to
work correctly, however, it is
recommended from safety
and maintenance points of
view, that all these instruc-
tions should have different
parameter number with
each other.)
Plural TMRBs have the
same number as their pa-
rameter.
(This is warning.)
