Frequently Asked Questions
What are the main differences between CJ2M-CPU31/32/33/34/35?
The main difference is program capacity: CPU31=5K, CPU32=10K, CPU33=20K, CPU34=30K, CPU35=60K steps. All have built-in EtherNet/IP and USB. Choose based on your program size requirements and future expansion needs.
Can I use existing CJ1 modules with this CJ2M CPU?
Yes, the CJ2M is fully compatible with all existing CJ1 I/O units, control units, and communication modules. This makes it ideal for upgrading existing CJ1 systems without replacing all modules.
What software do I need to program this PLC?
CX-Programmer (part of CX-One suite) is required for ladder logic programming. For structured text or function block, use CX-Programmer with appropriate options. Sysmac Studio can also be used for newer projects.
Is this PLC suitable for motion control applications?
Yes, with optional pulse I/O modules, the CJ2M can control up to 4 axes of stepper or servo motors. For more advanced motion control, consider the NJ series machine automation controllers with integrated motion.
How do I connect this PLC to an HMI or SCADA system?
Use the built-in EtherNet/IP port for modern HMI/SCADA connections. For legacy systems, add a serial communication module (RS-232C/RS-422/RS-485) for Modbus RTU or Host Link protocol connections.
