Alarm number ContentsFaulty location/corrective action
SPE WITHOUT SP If SP is missing, add it in proper posi-
tion. If the SPE is unnecessary, re-
move it.
There is no SP that corresponds to
this SPE.
END IN SP If SPE is missing, add it in proper posi-
tion. If END is in wrong place, move it
to proper position.
END is found between SP and SPE.
DUPLICATE P ADDRESS If some of these SPs are unnecessary,
remove them. If all of these SPs is
necessary, assign other P–addresses
to them to make all SPs unique.
Same P–address is used in plural
SPs.
DUPLICATE TMRB NUMBER
(WARNING)
If some of them are unnecessary, re-
move them. If all of them are neces-
sary, assign other number to parame-
ter 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
program has a possibility to work cor-
rectly, however, it is recommended
from safety and maintenance points of
view, that all these instructions should
have different parameter number with
each other.)
Plural TMRBs have the same number
as their parameter. (This is warning.)
ILLEGAL TMRB NUMBER If unnecessary, remove it. Assign cor-
rect number not to exceed the maxi-
mum number defined by each PMC
model
TMRB has parameter number that is
out of range.
DUPLICATE TMR NUMBER
(WARNING)
If some of them are unnecessary, re-
move them. If all of them are neces-
sary, assign other number to parame-
ter 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
program has a possibility to work cor-
rectly, however, it is recommended
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 cor-
rect number not to exceed the maxi-
mum number 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/
CALLU is not found.
UNAVAILABLE INSTRUCTION Confirm that this ladder program is cor-
rect one. If this program is correct one,
all these unsupported instructions
have to be removed.
Unsupported instruction for this PMC
model is found.
SP IN BAD LEVEL SP can be used at top of a subpro-
gram. Correct it so that no SP exists in
other place.
SP is found in wrong place.
