NOTE
The
calculated
CRC
(cyclic

sum)
values
are

If
the
calculated
checksum
is
different
from
the
stored
correct
sum,
the

on
the
quantity
line.
The
CRC
of
the
peripheral
unit
programs
(PDEINP
and
PDEDPS)
is
checked
before
each
delivery
is
enabled.
If
the
calculated
value
of
the
peripheral
unit
checksum
does
not
match
the
correct
