11 2 5-2 The CPM1A Cycle Th e overall flow of CPM1A operation is as shown in the following flowchart. The CPM1A is initialized internally when the power is turned on. If no errors are detected, the overseeing processes, program execution, I/O refreshing, and Peripheral Device servicing are executed consecutively (cyclically).
! 11 3 5-3 Self-diagnosis Functions Th e CPM1A is equipped with a variety of self-diagnosis functions to help identify and correct errors that might occur and reduce down time. PC errors are divided into 2 categories based on the severity of the errors.
11 4 Message F ALS No. Meaning and appropriate response Power interruption (no message) None Power has been interrupted for at least 10 ms (2 ms for DC power types.) Check power supply voltage and power lines. T ry to power-up again. MEMOR Y ERR F1 AR 1308 ON: An unspecified bit area exists in the user program.
11 5 F ALS(07) i s a n instruction that causes a fatal error . The following will occur when an F ALS(07) instruction is executed: 1, 2, 3... 1. Program execution will be stopped and outputs will be turned OFF . 2. The ERR/ALM indicator on the CPU Unit will be lit.
11 6 Three levels of program checking are available. The desired level must be des- ignated to indicate the type of errors that are to be detected. The following table provides the error types, displays, and explanations of all syntax errors.
11 7 5-6 T roubleshooting Flowcharts Use the following flowcharts to troubleshoot errors that occur during operation. Main Check Check for non-fatal errors. (See page 120.) Error Replace the CPU Unit. PWR indicator lit? RUN indicator lit? ERR/ALM indicator flashing? Is I/O sequence normal? Operating environment nor- mal? Operation stopped.
11 8 Power Supply Check PWR indicator not lit. Replace the CPU Unit. Is power being supplied? Is voltage adequate? Are there any loose terminal screws or bro- ken wires? Connect power supply . Is PWR indicator lit? Set supply voltage within acceptable limits.
11 9 Fatal Error Check Identify the error, eliminate its cause, and clear the error . Follow the Memory Error Check flowchart if a memory error has occurred. Is the ERR/ALM indicator lit? Determine the cause of the error with a Peripheral Device. End RUN indicator not lit.
120 Non-fatal Error Check Identify the error, eliminate its cause, and clear the error . ERR/ALM indicator flashing. Is a non-fatal error indicated? Is the ERR/ALM indi- cator flashing? Replace the CPU Unit. End Determine the cause of the error with a Peripheral Device.
121 I/O Check The I/O check flowchart is based on the following ladder diagram section. 01003 00002 (LS1) 00003 (LS2) SOL1 malfunction. SOL1 01003 Ye s Monitor the ON/OFF status of IR 01003 with a Peripheral Device. No Is the IR 01003 out- put indicator operat- ing normally? Check the voltage at the IR 01003 terminals.
122 Ye s No Check the voltage at the IR 00002 and IR 00003 terminals. Check operation by using a dummy input signal to turn the input ON and OFF . No Replace the CPU Unit or Expansion I/O Unit. Are the terminal screws loose? Operation O.K.? Wire correctly .
123 Environmental Conditions Check Consider using a fan or cooler . Is the ambient temperature below 55 ° C? Is the ambient temperature above 0 ° C? Is noise being controlled? Is the installation envi- ronment okay? Consider using a heater . Consider using an air conditioner .
124 Memory Error Check Memory error occurred. AR 1309 ON? AR 1314 ON? AR 1308 ON? Replace the CPU Unit. Check/correct data backed up by capacitor and clear error .
125 5-7 Maintenance Inspections In order that your SYSMAC system operates in optimum condition, be sure to carry out daily or periodical inspections. Inspection Items Th e main system components of a SYSMAC system are semiconductors, and it contains few components with limited lifetimes.
126 5-8 Handling Precautions • T urn the power OFF before replacing the Unit. Note Before restarting operation, transfer the contents of the DM an d H R ar e as t o t h e CPU Unit that was changed and then start operation. • If a Unit is found to be faulty and is replaced, check the Unit again to ensure there is no error .
