9 / 30 page  9 CJ2M-CPU3 @/-CPU1@/-MD21@ Function Specifications Functions Description Cycle Time Management Minimum Cycle Time A minimum cycle time can be set. (0.2 to 32,000 ms; Unit: 0.1 ms) The minimum cycle time setting can be changed in MONITOR mode. Cycle Time Monitoring The cycle time is monitored. (0.01 to 40,000 ms; Unit: 0.01 ms) Background Processing Instructions with long execution times can be executed over multiple cycles to prevent fluctuations in the cycle time. Unit (I/O) Management Basic I/O Units, Special I/O Units, and CPU Bus Units I/O Refreshing Cyclic Refreshing Cyclic refreshing of Basic I/O Units, Special I/O Units, and CPU Bus Units Immediate Refreshing I/O refreshing by immediate refreshing instructions Refreshing by IORF I/O refreshing by IORF instruction Unit Recognition at Startup The number of units recognized when the power is turned ON is displayed. Basic I/O Units Input Response Time Setting The input response times can be set for Basic I/O Units. The response time can be increased to reduce the effects of chattering and noise at input contacts. The response time can be decreased to enable detecting shorter input pulses. Load OFF Function All of the outputs on Basic I/O Units can be turned OFF when an error occurs in RUN or MONITOR mode. Basic I/O Unit Status Monitoring Alarm information can be read from Basic I/O Units and the number of Units recognized can be read. Reading/writing data using instructions for specific Units Special instructions can be used to read/write required data for specific Units at high speed. Special I/O Units and CPU Bus Units Unit Restart Bits to Restart Units A Special I/O Unit or CPU Bus Unit can be restarted. Configuration Management Automatic I/O Allocation at Startup I/O words can be automatically allocated to the Basic I/O Units that are connected in the PLC to start operation automatically without registering Units into I/O tables. I/O Table Creation The current unit configuration can be registered in I/O tables to prevent it from being changed, to reserve words, and to set words. Rack/Slot First Word Settings The first words allocated to a Units on the Racks can be set. Memory Management Holding I/O Memory when Changing Operating Modes The status of I/O memory can be held when the operating mode is changed or power is turned ON. The forced-set/reset status can be held when the operating mode is changed or power is turned ON. File Memory Files (such as program files, data files, and symbol table files) can be stored in Memory Card, EM File Memory, or Comment Memory. Built-in Flash Memory The user program and Parameter Area can be backed up to an internal flash memory when they are transferred to the CPU Unit. EM File Function Parts of the EM Area can be treated as file memory. Storing Comments I/O comments can be stored as symbol table files in a Memory Card, EM file memory, or comment memory. EM Configuration EM Area can be set as trace memory or EM file memory. Memory Cards Automatic File Transfer at Startup A program file and parameter files can be read from a Memory Card when the power is turned ON. Program Replacement during PLC Operation User programs can be transferred from a Memory Card to CPU Unit during operation. Function for Reading and Writing Data from a Memory Card Data in I/O memory in the CPU Unit can be written to a Memory Card in CSV/TXT format. Data in CSV/TXT format in the Memory Card can be read to I/O memory in the CPU Unit. |
