Meaning:
Plural TMRs, CTRs, TMRBs, DIFUs, or DIFDs have
the same number as their parameter.
This is warning.
Solution:
If some of them are unnecessary, remove them. If all
of them are necessary, assign other number to pa-
rameter 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 num-
ber with each other.
