11 / 29 page 11 CJ2M-CPU3 @/-CPU1@/-MD21@ *14.Supported only by the CJ2M-CPU3@. Function Description Function Blocks Standard programming can be encapsulated as function blocks. Languages in Function Block Definitions Ladder programming or structured text Debugging Online Editing The program can be changed during operation (in MONITOR or PROGRAM mode), except for block programming areas. Force-Set/Reset Specified bits can be set or reset. Force-set/reset to the EM Area is enabled by specifying a start bank in parameter setting. Differentiate Monitoring ON/OFF changes in specified bits can be monitored. Data Tracing The specified I/O memory data can be stored in the trace memory in the CPU Unit. The triggers can be set. Continuous Tracing The trace data can be uploaded during data tracing using CX-Programmer, which enables continuously logging the data by constantly uploading the trace data. Automatically starting tracing when operation starts Data tracing can be automatically started when operation is started (i.e., when the operating mode is changed from PROGRAM mode to MONITOR or RUN mode). Storing Location of Error when an Error Occurs The location and task number where execution stopped for a program error is recorded. Program Check The programs can be checked for items such as no END instruction and FALS/FAL errors at startup. Self- diagnosis and Restoration Error Log A function is provided to store predefined error codes in CPU Unit, error information, and time at which the error occurred. CPU Error Detection CPU Unit WDT errors are detected. User-defined Failure Diagnosis Errors can be generated for user-specified conditions: Non-fatal errors (FAL) and fatal errors (FALS). Program section time diagnosis and program section logic diagnosis are supported (FPD instruction). Load OFF Function This function turns OFF all outputs from Output Units when an error occurs. RUN Output The RUN output from the CJ1W-PA205R turns ON while CPU Unit is in RUN mode or MONITOR mode. Basic I/O Load Short-circuit Detection This function provides alarm information from Basic I/O Units that have load short-circuit protection. Failure Point Detection The time and logic of an instruction block can be analyzes using the FPD instruction. CPU Standby Detection This function indicates when the CPU Unit is on standby because all Special I/O Units and CPU Bus Units have not been recognized at the startup in RUN or MONITOR mode. Non-fatal Error Detection System FAL Error Detection (User-defined non-fatal error) This function generates a non-fatal (FAL) error when the user-defined conditions are met in program. Duplicate Refreshing Error Detection This function detects an error when an immediate refreshing Instruction in an interrupt task is competing with I/O refreshing of a cyclic task. Basic I/O Unit Error Detection This function detects the errors in Basic I/O Units. Backup Memory Error Detection This function detects errors in the memory backup of the user programs and parameter area (backup memory). PLC Setup Error Detection This function detects setting errors in the PLC Setup. CPU Bus Unit Error Detection This function detects an error when there is an error in data exchange between the CPU Unit and a CPU Bus Unit. Special I/O Unit Error Detection This function detects an error when there is an error in data exchange between the CPU Unit and a Special I/O Unit. Tag Memory Error Detection *14 This function detects errors in tag memory. Battery Error Detection This function detects an error when a battery is not connected to the CPU Unit or when the battery voltage drops. CPU Bus Unit Setting Error Detection This function detects an error when the model of a CPU Bus Unit in the registered I/O tables does not agree with the model that is actually mounted in the PLC. Special I/O Unit Setting Error Detection This function detects an error when the model of a Special I/O Unit in the registered I/O tables does not agree with the model of Unit that is actually mounted. Option Board Error Detection *14 This function detects the errors in Serial Option Board mounting status. Fatal Error Detection Memory Error Detection This function detects errors that occur in memory of the CPU Unit. I/O Bus Error Detection This function detects when an error occurs in data transfers between the Units mounted in Rack slots and the CPU Unit and detects when the End Cover is not connected to the CPU Rack or an Expansion Rack. Unit/Rack Number Duplication Error This function detects an error when the same unit number is set for two or more Units, the same word is allocated to two or more Basic I/O Units, or the same rack number is set for two or more Racks. Too Many I/O Points Error Detection This function detects an error when the total number of I/O points set in the I/O tables or the number of Units per Rack exceeds the specified range. I/O Setting Error Detection This function detects an error when the number of Units in the registered I/O tables does not agree with the actual number of Units that is mounted, or an Interrupt Unit has been connected in the wrong position, i.e., not in slot 0 to 4. |
