Be sure to read this manual before attempting to use the Unit and keep this manual close at hand for reference during operation /A WARNING It is extremely important that a pC and all PC Units be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PC System to the above-mentioned applications 3 Safety Precautions A Caution Execute online edit only after confirming that no adverse effects will be caused by extending the cycle time. Otherwise, the input signals may not be readable /Caution Confirm safety at the destination node before transferring a program to another node or changing the l o memory area. Doing either of these without confirming safety may result in injury 4 Application Precautions Observe the following precautions when using the Pc system Caution Failure to abide by the following precautions could lead to faulty operation of the PC or the system, or could damage the Pc or Pc Units. always heed these pre cautions Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines momentary power interruptions, or other causes Interlock circuits, limit circuits, and similar safety measures in external circuits (i.e, not in the Programmable Controller) must be provided by the customer. XIV Application Precautions Check the user program for proper execution before actually running it on the Unit Not checking the program may result in an unexpected operation Confirm that no adverse effect will occur in the system before attempting any of the following Not doing so may result in an unexpected operation Changing the operating mode of the Pc Force-setting/force- resetting any bit in memory Changing the present value of any word or any set value in memory Resume operation only after transferring to the new CPU Unit the contents of the DM and HR Areas required for resuming operation Not doing so may result in an unexpected operation Do not place objects on top of the cables. Doing so may break the cables Before touching the Unit, be sure to first touch a grounded metallic object in order to discharge any static built-up. Not doing so may result in malfunction or damage Do not touch the Expansion IyO Unit Connecting Cable while the power is being supplied in order to prevent any malfunction due to static electricity /Caution Always clear memory before beginning to program the CPM1, CPM1Aor SRM1 Although memory is cleared before the CPU Unit is shipped(except for bits with specific functions), AR 1314, which turns on when the internal capacitor cannot back up memory, may have turned on during shipment Caution If the CPM1 or CPM1A will be turned oFF for periods exceeding the data backup period of the internal capacitor, design the system so that it will not be intluenced if data in the dm, hr, and cnt areas is cleared when power is turned oFF /Caution Either switch the CPM1 or CPM1A to RUN or MONITOR mode, orturn OFF and oN power to the cPm1 or CPM1A after changing from a programming Device any data that is backed up in flash memory. This data includes the user program, read-only DM area(DM 6144 to DM 6599), and the PC Setup(DM 6600 to DM 6655). The user program and memory area data in the CPM1 or CPM1A are backed up either by an internal capacitor or in flash memory as shown in the following table Backup method Data Internal capacitor Read /write dm area dm 0000 to dm 0999, dm 1022, and DM1023 Error log area(M 1000 to DM 1021) HR area(HR 00 to HR 19) Counter area(CNT 000 to CNT 127) Flash memory ser program Read-only DM area (DM 6144 to DM 6599) PC Setup( DM 6600 to DM 6655 Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is turned OFF and all contents will be cleared the next time power is turned ON.(The PC Setup setting in DM 6601 can be used to back up this data Refer to details on the Pc Setup later in this manual for details. 2. The bits in the aR and sr areas have special functions and are set accord ing to these functions when power is turned ON Application Precautions The capacitor backup time depends on the ambient temperature, as shown in the following graph. The backup time, however, assumes that the capacitor is fully charged, which requires that power be supplied to the CPU Unit continu- ously for at least 15 minutes 10 mmmmmm 80 Ambient temperature oC) If the power remains OFF for a period exceeding the data backup period, AR 1314 will turn on to indicate that the capacitor can no longer back up data and the data backed up by the capacitor will be cleared. AR 131 4 will remain ON unless it is turned OFF using l/0 monitor operations, using memory clear operations, or from the user program If desired, the PC Setup setting in DM 6604 can be set to create a fatal error and thus stop the system when AR 1314 goes ON The data stored in flash memory will not be lost even if power remains OFF for a period exceeding the data backup period, because the data stored in flash memory will be read to the CPU Unit when the CPMi or CPM1Ais turned ON If the power is turned OFF without changing the mode from PROGRAM mode to run or MoNITOR mode after having made changes in the data that is backed up in flash memory, the changes will not be written to flash memory. If the power is then left OFF for more than 20 days (at 25C), the changes (i.e the contents of the RAM)will be erased and the data values will become unde fined Caution Be sure that the Srm1 system is not influenced by any undefined data if the data in the dm. he. or cnt area is cleared when the srml has been turned off for a period exceeding the data backup period of the internal lithium battery. If the AR 1414 flag is ON, the data will be held unless it is turned oFF using the l o Monitor operation, instructions, etc. The system can be stopped by designating DM 6604 in the Pc Setup so that a memory error occurs when the power inter ruption hold area is not held (with AR 1314 ON) A lithium battery in the CPU Unit is used to back up the counter values and the contents of the dm area. and hr area the deterioration of the lithium batter capacity depends on the ambient temperature. The standard service life is 12 years at an ambient temperature of 40c when operating 8 hours a day If the power remains off for a period exceeding the data backup period, the contents of the Data Memory(DM), Hold Relay(HR), and Counter(CNT) Areas in the CPU Unit may be cleared and the AR 1314 flag(which turns ON When the power interruption hold area is not held)may turn ON If the contents of the CPU Unit's program area are lost, the program stored in flash memory will be read to the CPU Unit's program area when the SRM1 is started up because the contents in the read- only area DM 61 44 through DM 6599)and PC setup(DM 6600 through DM 6655) will be written to flash memory.
