FAQ for CJ2M-CPU34
When should I choose CPU34 over CPU33?
Choose CPU34 (30K steps) over CPU33 (20K steps) when your program exceeds 20K steps or you anticipate significant program growth. The price difference is usually small compared to the benefit of extra capacity.
Can this PLC communicate with multiple HMIs simultaneously?
Yes, the built-in EtherNet/IP port supports multiple simultaneous connections. You can connect HMIs, SCADA systems, and programming devices simultaneously without additional communication modules.
What happens when the battery dies?
The PLC will continue running but RAM data will be lost on power cycle. Replace the battery (CJ1W-BAT01) within 30 days of the low battery warning. Program and parameters stored in flash memory are retained without battery.
Is training available for programming this PLC?
Omron offers official CX-Programmer training courses. Many distributors also provide programming training. Online resources and documentation are available on Omron's industrial website.
