Info

• When creating an AUTOEXEC.IOM file from a Programming Device (a Programming Console orthe CX-Programmer) to automatically transfer data at startup, set the first write address toD20000 and be sure that the size of data written does not exceed the size of the DM Area. Whenthe data file is read from the Memory Card at startup, data will be written in the CPU Unit startingat D20000 even if another address was set when the AUTOEXEC.IOM file was created. Also, ifthe DM Area is exceeded (which is possible when the CX-Programmer is used), the remainingdata will be written to the EM Area.• The user program and parameter area data in the CJ2 CPU Units are backed up in the built-inflash memory. The BKUP indicator will light on the front of the CPU Unit when the backup operationis in progress. Do not turn OFF the power supply to the CPU Unit when the BKUP indicator islit. The data will not be backed up if power is turned OFF.• Check the user program and Unit parameter settings for proper execution before actually runningthem on the Unit. Not checking the program and parameter settings may result in an unexpectedoperation.• When setting a Special I/O Unit or CPU Bus Unit in the I/O tables, carefully check the safety of thedevices at the connection target before restarting the Unit.• Do not turn OFF the power supply to the PLC when reading or writing a Memory Card. Also, donot remove the Memory Card when the BUSY indicator is lit. Doing so may make the MemoryCard unusable.To remove a Memory Card, first press the memory card power supply switch and then wait for theBUSY indicator to go out before removing the Memory Card.• When restoring data, carefully check that the selected data is the correct data to be restoredbefore executing the restore operation. Depending on the contents of the selected data, the controlsystem may operate unexpectedly after the data is restored.• Some Special I/O Units and CPU Bus Units operate with parameters stored in the CPU Unit (e.g.,words allocated in DM Area, data link tables, or Ethernet settings). Information on restrictions willbe displayed in the Information Area in the PLC Backup Tool if there are any restrictions for theselected CPU Bus Unit or Special I/O Unit. Check the restrictions, and then be sure to select boththe CPU Unit and the CPU Bus Unit or Special I/O Unit when backing up or restoring data. Thecontrol system may operate unexpectedly if the equipment is started with the data backed up orrestored without selecting both Units.• Information on restrictions will be displayed in the Information Area in the PLC Backup Tool if thedata to be stored includes a Unit that has restrictions on backup. Check the information on restrictionsand take the required countermeasures. The control system may operate unexpectedlywhen the equipment is operated after the data is restored• Before restoring data during PLC operation, be sure that there will be no problem if PLC operationstops. If the PLC stops at an unexpected time, the control system may operate unexpectedly.• Be sure to turn the PLC power supply OFF and then back ON after restoring data. If the power isnot reset, the system may not be updated with the restored data, and the control system mayoperate unexpectedly.• Data on forced status can be backed up but it cannot be restored. Perform the procedure to forcesetor force-reset bits from the CX-Programmer as required before starting operation after restoringdata that includes forced status. Depending on the difference in the forced status, the controlsystem may operate unexpectedly.• If a symbol or memory address (only symbols are allowed for ST programming) is specified for thesuffix of an array variable in ladder or ST programming, be sure that the specified element numberdoes not exceed the maximum memory area range.Specifying an element number that exceeds the maximum range of the memory area specified forthe symbol will result accessing data in a different memory area, and may result in unexpectedoperation.• If a symbol or address is specified for an offset in a ladder diagram, program so that the memoryarea of the start address is not exceeded when the offset is specified indirectly using a wordaddress or symbol.If an indirect specification causes the address to exceed the area of the start address, the systemwill access data in other area, and unexpected operation may occur.28 CJ2 CPU Unit Software User’s Manual
External Circuits• Always turn ON power to the PLC before turning ON power to the control system. If the PLCpower supply is turned ON after the control power supply, temporary errors may result in controlsystem signals because the output terminals on DC Output Units and other Units will momentarilyturn ON when power is turned ON to the PLC.• Install external breakers and take other safety measures against short-circuiting in external wiring.Insufficient safety measures against short-circuiting may result in burning.CJ2 CPU Unit Software User’s Manual29
