Press the CLR Key to bring up the initial display.CLR000002. Press the SRCH Key. An input prompt will appear requesting the desiredcheck level.SRCH00000PROG CHKCHK LBL(0Ć2)?3. Input the desired check level (0, 1, or 2). The program check will begin whenthe check level is input, and the first error found will be displayed. If no errorsare found, the following display will appear.A000017PROG CHKEND (001)00.1KWNote Refer to 5-4 Programming Errors for details on check levels and theprogramming errors that may be displayed during a program check.4. Press the SRCH Key to continue the search.
The next error will be displayed. Continue pressing the SRCH Key to continue the search.The search will continue until an END(01) instruction or the end of ProgramMemory is reached.If errors are displayed, edit the program to correct the errors and check the program again. Continue checking the program until all errors have been corrected.4-5-5 Test Run in MONITOR ModeSwitch the CPM2A in MONITOR mode and check the operation of the program.1, 2, 3...1. Set the Programming Console’s mode switch to MONITOR mode.MONITORRUNPROGRAM<MONITOR>BZ2. Press the CLR Key to bring up the initial display.CLR000003.
Force-set the start input bit (IR 00000) from the Programming Console tostart the program.LDMONTRSET00000LD0000000000^ OFF00000ONThe cursor in the lower left corner of the display indicates that the force set isin progress. The bit will remain ON as long as the Set Key is held down.4. The output indicator for output IR 01000 will flash ten times if the program isoperating correctly. The indicator should go OFF after ten one-secondflashes.There is a mistake in the program if the output indicator doesn’t flash. In thiscase, check the program and force set/reset bits to check operation.129SECTION 5Test Runs and Error ProcessingThis section describes procedures for test runs of CPM2A operation, self-diagnosis functions, and error processing to identifyand correct the hardware and software errors that can occur during PC operation.5-15-25-35-45-55-65-7Initial System Checks and Test Run Procedure .

Always clear memory before beginning to program the CPM2A. Althoughmemory is cleared before the CPU Unit is shipped, the contents of the DM,HR, AR, and counter areas may change in transit. See 4-4-2 ClearingMemory for details on the All Clear operation.2. See 1-3-3 Operating Mode at Startup to determine what mode the CPM2Awill enter when the power is turned on.5-1-2 Flash Memory PrecautionsObserve the following precautions to protect the flash memory and ensureproper operation.1, 2, 3...1. If changes are made in the read-only DM area (DM 6144 through DM 6599)or PC Setup (DM 6600 through DM 6655), the PC’s operating mode must bechanged to write the new contents to flash memory. If backup battery ischanged before the changes are written to flash memory, the changes willbe lost.The changes can be saved by switching the CPM2A to RUN or MONITORmode or turning the CPM2A off and then on again.2.
When contents of the program, read-only DM (DM 6144 through DM 6599),or PC Setup (DM 6600 through DM 6655) have been changed, startup processing will take up to 1,200 ms longer than usual. Be sure to take this onetime startup delay into account if it may affect operations.3. If one of the following three operations is performed in MONITOR or RUNmode, the CPM2A’s cycle time will be extended by up to 1,200 ms and interrupts will be disabled while the program or PC Setup is being overwritten.• Program changes with the online edit operation• Changes to the read-only DM area (DM 6144 through DM 6599)• Changes to the PC Setup (DM 6600 through DM 6655)A “SCAN TIME OVER” error won’t occur during these operations.
Be sure totake this delay in the CPM2A’s I/O response times into account when performing online editing.5-1-3 CPM2A Test Run Procedure1, 2, 3...1321. Power Supply Applicationa) Check the CPM2A’s power supply voltage and terminal connections.b) Check the I/O devices’ power supply voltage and terminal connections.c) Turn on the power supply and check that the “PWR” indicator lights.d) Use a Programming Device to set the CPM2A to PROGRAM mode.SectionSelf-diagnostic Functions5-22.
I/O Wiring Checksa) With the CPM2A in PROGRAM mode, check the output wiring by turningon the output bits with the force set and force reset operations.Refer to 4-4-24 Force Set, Reset for details.b) Check the input wiring with the CPM2A’s input indicators or a Programming Device’s monitor operations.3.
