Word values are retainedwhen the power is turned off.Used to store the time of occurrence anderror code of errors that occur. Thesewords can be used as ordinary read/writeDM when the error log function isn’tbeing used.Cannot be overwritten from program.Used to store various parameters thatcontrol PC operation.1. IR and LR bits that area not used for their allocated function can be used as work bits.2.
The contents of the HR area, LR area, Counter area, and read/write DM are backed up by theCPU Unit’s battery. If the battery is removed or fails, the content of these area will be lost andunstable.3. When a TC numbers is used as a word operand, the timer or counter PV is accessed; when usedas bit operand, its Completion Flag is accessed.4.
Data is DM 6144 to DM 6655 cannot be overwrite from the program, but they can be changedfrom a Programming Device.5. The program and data in DM 6144 to DM 6655 are stored in flash memory.4-84.qUNIT SPECIFICATIONS AND COMPONENTSI/O Terminal – IR Bit AllocationCPU UnitCPM2A-30CD -I/O18 inputs12 outputsCPM2A-40CD -24 inputs16 outputsCPM2A-60CD -36 inputs24 outputsqCPU Unit Terminals00000 to 00011 (IR 00000 to IR 00011) and00100 to 00105 (IR 00100 to IR 00105)01000 to 01007 (IR 01000 to IR 01007) and01100 to 01103 (IR 01100 to IR 01103)00000 to 00011 (IR 00000 to IR 00011) and00100 to 00111 (IR 00100 to IR 00111)01000 to 01007 (IR 01000 to IR 01007) and01100 to 01107 (IR 01100 to IR 01107)00000 to 00011 (IR 00000 to IR 00011),00100 to 00111 (IR 00100 to IR 00111) and00200 to 00211 (IR 00200 to IR 00211)01000 to 01007 (IR 01000 to IR 01007),01100 to 01107 (IR 01100 to IR 01207) and01200 to 01207 (IR 01200 to IR 01207).Expansion Unit AllocationUp to 3 Expansion Units can be connected to a CPU Unit.

No changes can be made to the internal data inthe run mode.4-124.•UNIT SPECIFICATIONS AND COMPONENTSA look at the Programming ConsoleIn order for the PLC to operate, you must first put a program into the memory. The program is madeby sequentially inputting commands using the Programming Console.Please note that CQM1−−PRO01E/C200H−−PRO27E can be used with CPM1A, CPM1, CQM1,C200HS AND C200HX.KeyboardSFTNOTANDORCNTTRLRHRLDOUTTIMDMCH*CONT#7NumericalkeysSHIFTFUN89EXTCHGSRCH6PLAYSETDELMONTR3RECRESETINSCLRVERWRITEE4F5B1C2A0DCommandOperation4-134.qUNIT SPECIFICATIONS AND COMPONENTSPassword InputThe PLC has a password control to prevent unauthorized access to its program. The PLC alwaysprompts you for the password when power is first applied or after programming console is installedwhen the PLC is in the operation mode.
