CPUOverview CJ1G/CJ1H CPUs Mean Optimized Performance J FeaturesEnhancingFlexibility andFunctionality 0.02 s executiontime per basic instruction. Ultra-compact design. Built-in flash memory for battery-freeoperation. Up to 64 MB of auxiliary flash memory available for many time-saving programming uses. The efficiency of transfers betweenthe CPU and Special I/O Modules has been optimized, further improving overall system performance. Floating-point decimal numbers can be easily convertedto ASCII characterstring data for display on an HMI (in the HMIs characterstring display objects). For process control applications,use the PID WITH AUTOTUNING instruction to calculate PID constants automatically. Using the limit cycle method for tuning, autotuningis completed quickly. This is particularly effectivefor multi-loop PID control. Built-in peripheral and RS-232 ports.

B-11 ProgrammableControllerCJ1CPUOverview CJ1M CPUs Offer Specialized Functionality J SpecialFunctions Smallest CJ1 in physical size CPU11, CPU12 and CPU13 are just 1 1/4 wide. Up to 64 MB auxiliary flash memory available for many time-saving programming uses. Serial PLC Link allows simple communicationamong 9 CJ1 PLCs (1 master, 8 slaves). Same instruction set as the larger CJ1G/H and CJ1H/H the only difference is no EM available in the CJ1M. A Pulse I/O instruction takes advantageof positioning capabilities in CPU21, CPU22 and CPU23. Built-in high-speed counterin CPU21, CPU22 and CPU23. Easy terminal block connectionfor built-in I/O (CPU21, CPU22 and CPU23). CPU21, CPU22 and CPU23 have built-in pulse catch inputs which will detect pulses that are quicker than the CPU cycle time. Built-in peripheral and RS-232 ports.
