Correct the error as indicated and continue operation.MessageMeaning and appropriate responseREPL ROMAn attempt was made to write to write-protected memory. Set bits00 to 03 of DM 6602 to “0.”PROG OVER The instruction at the last address in memory is not NOP(00).
Eraseall unnecessary instructions after END(01).ADDR OVER An address was set that is larger than the highest memory addressin Program Memory. Input a smaller address.SETDATAFALS 00 has been input, and “00” cannot be input. Reinput theERRdata.I/O NO. ERR A data area address has been designated that exceeds the limit ofthe data area, e.g., an address is too large. Confirm therequirements for the instruction and re-enter the address.Note Refer to the relevant Support Software Operation Manual for details on errorsthat may appear when operating the SSS or SYSMAC-CPT Support Software.5-4Programming ErrorsThese errors in program syntax will be detected when the program is checkedusing the Program Check operation.Three levels of program checking are available. The desired level must be designated to indicate the type of errors that are to be detected. The following tableprovides the error types, displays, and explanations of all syntax errors.
Checklevel 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.TypeMessageA?????CIRCUIT ERROPERANDERRA constant entered for the instruction is not within definedvalues. Change the constant so that it lies within theproper range.NO ENDINSTRLOCN ERRThere is no END(01) in the program.
Write END(01) at theend of the program.An instruction is in the wrong place in the program. Checkinstruction requirements and correct the program.A JME(05) instruction is missing for a JMP(04) instruction.Correct the jump number or insert the proper JME(05)instruction.JME UNDEFD136Meaning and appropriate responseThe program has been damaged, creating a non-existentfunction code. Re-enter the program.The number of LD instructions (LD or LD NOT) does notmatch the number of logic block instructions (OR LD orAND LD).Check your program.DUPLThe same jump number or subroutine number has beenused twice. Correct the program so that the same numberis only used once for each.SBN UNDEFDAn SBN(92) has not been programmed with the samesubroutine number as an SBS(91) instruction in theprogram. Correct the program.STEP ERRSTEP(08) with a section number and STEP(08) without asection number have been used incorrectly.
CheckSTEP(08) programming requirements and correct theprogram.SectionTroubleshooting FlowchartsTypeMessageBIL-ILC ERRJMP-JME ERRSBN-RET ERRC5-55-5Meaning and appropriate responseIL(02) and ILC(03) are not used in pairs. Check theprogram before processing.JMP(04) and JME(05) are not used in pairs. Check theprogram before processing.RET(93) has not been used properly or the relationshipbetween SBN(92) and RET(93) is not correct. Correct theprogram.COIL DUPLThe same bit is being controlled (i.e., turned ON and/orOFF) by more than one instruction (e.g., OUT, OUT NOT,DIFU(13), DIFD(14), KEEP(11), SFT(10)). This erroroccurs when the same number is used for the timer andcounter instructions.
Although this is allowed for certaininstructions, check instruction requirements to confirm thatthe program is correct or rewrite the program so that eachbit is controlled by only one instruction.JMP UNDEFDJME(05) has been used with no JMP(04) with the samejump number. Add a JMP(04) with the same number ordelete the JME(05) that is not being used.SBS UNDEFDA subroutine exists that is not called by SBS(91). Programa subroutine call in the proper place, or delete thesubroutine if it is not required.Troubleshooting FlowchartsUse the following flowcharts to troubleshoot errors that occur during operation.Main CheckErrorPWR indicator lit?NoCheck power supply.

Poor environmental conditions,however, can lead to deterioration of the electrical components, making regularmaintenance necessary.The standard period for maintenance checks is 6 months to 1 year, but more frequent checks are required if the PC is operated in more demanding conditions.If the criteria are not met, adjust to within the specified ranges.Inspection itemsDetailsCriteriaRemarksPower supplyDetermine whether the voltage fluctuationat the power supply terminals is withinspecifications.Within the voltage variationrange (see note)TesterEnvironmentalconditionsIs the ambient temperature inside thepanel appropriate?Is the ambient humidity inside the panelappropriate?Has dirt or dust collected?Is the voltage fluctuation measured at theI/O terminals within the standard range?Are all units securely installed?Are all connection cables and connectorsinserted completely and locked?Are any of the external wiring screwsloose?Are any of the external wiring cablesfrayed?Contact output relay0 to 55_CThermometer10% to 85% RH with nocondensationNoneEach I/O terminal mustconform to the specificationsNothing is looseNothing is looseHygrometerNothing is loosePhillips screwdriverNo external abnormalitiesVisual inspectionElectrical:Resistance load:300,000 operationsInductive load:100,000 operations---I/O power supplyInstallation statusProduct service lifeMechanical:10,000,000 operations5 yearsBattery (CPM2A-BAT01)Visual inspectionTesterPhillips screwdriverVisual inspection---Note Power supply voltage variation range.Power supplyRequired ToolsAllowable voltage fluctuation range100 to 240 VAC85 to 264 VAC24 VDC20.4 to 26.4 VDCStandard Tools (Required)• Screwdrivers (Phillips and flat-blade)• Voltage tester or digital voltage meter• Industrial alcohol and a cotton clothMeasurement Devices (May be Needed)• Synchroscope• Cathode-ray oscilloscope• Thermometer, hygrometerNote Do not attempt to disassemble, repair, or modify the PC in any way.145SectionBattery Replacement5-75-7Battery ReplacementIf power has not been supplied to the PC for an extended period of time, turn ONthe power supply for at least 5 minutes before replacing the battery.Turn OFF the power supply to the PC before replacing the battery.Use the procedure below when replacing the battery.
