Frequently Asked Questions
What's the difference between CPU13 and CPU33?
CPU13 has USB only (no built-in EtherNet/IP), while CPU33 has both USB and EtherNet/IP. Choose CPU13 for cost savings when Ethernet connectivity isn't needed, or add Ethernet via communication module if needed later.
Can I add Ethernet communication to CPU13?
Yes, add a CJ1W-EIP21 EtherNet/IP unit or CJ1W-ETN21 Ethernet unit to the CPU rack. This provides flexibility to add Ethernet only when needed while keeping initial costs lower.
Is CPU13 suitable for retrofitting older CJ1 systems?
Yes, CPU13 is fully compatible with CJ1 modules and offers a cost-effective upgrade path. The USB port makes programming easier than older CJ1 CPUs that required serial connections.
When should I choose CPU13 over CPU33?
Choose CPU13 when: budget is primary concern, no Ethernet needed, serial communication suffices, or Ethernet will be added via module. Choose CPU33 when built-in Ethernet is needed for HMI, SCADA, or data collection.
