Programming Errors Section 5-4
Check level 0 checks for type A, B, and C errors; check level 1, for type A and
B errors; and check level 2, for type A errors only.
Type Message Meaning and appropriate response
A ???? The program has been damaged, creating a non-existent
function code. Re-enter the program.
CIRCUIT ERR The number of LD instructions (LD or LD NOT) does not
match the number of logic block instructions (OR LD or
AND LD).Check your program.
OPERAND ERR A constant entered for the instruction is not within defined
values. Change the constant so that it lies within the proper
range.
NO END INSTR There is no END(01) in the program. Write END(01) at the
end of the program.
LOCN ERR An instruction is in the wrong place in the program. Check
instruction requirements and correct the program.
JME UNDEFD A JME(05) instruction is missing for a JMP(04) instruction.
Correct the jump number or insert the proper JME(05)
instruction.
DUPL The same jump number or subroutine number has been
used twice. Correct the program so that the same number
is only used once for each.
SBN UNDEFD An SBN(92) has not been programmed with the same sub-
routine number as an SBS(91) instruction in the program.
Correct the program.
STEP ERR STEP(08) with a section number and STEP(08) without a
section number have been used incorrectly. Check
STEP(08) programming requirements and correct the pro-
gram.
B IL-ILC ERR IL(02) and ILC(03) are not used in pairs. Correct the pro-
gram so that each IL(02) has a unique ILC(03). Although
this error message will appear if more than one IL(02) is
used with the same ILC(03), the program will executed as
written. Make sure your program is written as desired
before proceeding.
JMP-JME ERR JMP(04) and JME(05) are not used in pairs. Make sure
your program is written as desired before proceeding.
SBN-RET ERR RET(93) has not been used properly or the relationship
between SBN(92) and RET(93) is not correct. Correct the
program.
C COIL DUPL The same bit is being controlled (i.e., turned ON and/or
OFF) by more than one instruction (e.g., OUT, OUT NOT,
DIFU(13), DIFD(14), KEEP(11), SFT(10)). Although this is
allowed for certain instructions, check instruction require-
ments to confirm that the program is correct or rewrite the
program so that each bit is controlled by only one instruc-
tion.
JMP UNDEFD JME(05) has been used with no JMP(04) with the same
jump number. Add a JMP(04) with the same number or
delete the JME(05) that is not being used.
SBS UNDEFD A subroutine exists that is not called by SBS(91). Program
a subroutine call in the proper place, or delete the subrou-
tine if it is not required.
