Alarm number ContentsFaulty location/corrective action
DUPLICATE TMR NUMBER
(WARNING)
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 instruc-
tions with same parameter number will
never be active simultaneously at one
time, the Ladder program has a possibility
to work correctly, however, it is recom-
mended from safety and maintenance
points of view, that all these instructions
should have different parameter number
with each other.)
Plural TMRs have the same number as
their parameter.
(This is warning.)
ILLEGAL TMR NUMBER If unnecessary, remove it. Assign correct
number not to exceed the maximum num-
ber defined by each PMC model.
TMR has parameter number that is out of
range.
NO SUCH SUBPROGRAM If it calls wrong subprogram, correct it. If the
subprogram is missing, create it.
Subprogram that is called by CALL/CAL-
LU is not found.
UNAVAILABLE INSTRUCTION Confirm that this ladder program is correct
one. If this program is correct one, all these
unsupported instructions have to be re-
moved.
Unsupported instruction for this PMC
model is found.
SP IN BAD LEVEL SP can be used at top of a subprogram.
Correct it so that no SP exists in other
place.
SP is found in wrong place.
LADDER PROGRAM IS BROKEN This ladder program must be all cleared
once, and remake ladder program.
Ladder program may be broken by some
reason.

CALL/CALLU IN BAD LEVEL CALL/CALLU must be used in Level 2 or in
subprograms. Do not use any other
places.
