Type Meaning and appropriate responseMessage
B
IL-ILC ERR IL(02) and ILC(03) are not used in pairs. Check the
program before processing.
JMP-JME ERR JMP(04) and JME(05) are not used in pairs. Check the
program before processing.
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)). This error
occurs when the same number is used for the timer and
counter instructions. Although this is allowed for certain
instructions, check instruction requirements to confirm that
the program is correct or rewrite the program so that each
bit is controlled by only one instruction.
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
subroutine if it is not required.
