DUPLICATE TMR NUMBER
(WARNI)
If some of them are unnecessary,
remove them. If all of them are
necessary, assign other number to
parameter of them to make them unique.
(If two or more instructions with same
parameter number will never be active
simultaneously at one time, the Ladder
program has a possibility to work
correctly, however, it is recommended
from safety and maintenance points of
view, that all these instructions should
have different parameter number with
each other.)
