System Integration Notes
The CJ1W-EIP21 module requires installation in a CJ1-series PLC rack with appropriate power supply capacity. For optimal performance in industrial networks, we recommend using shielded Ethernet cables with proper grounding. The module supports both implicit (I/O) and explicit (message) communication modes, providing flexibility for various automation architectures. When planning your system, consider the total network load and connection requirements to ensure optimal performance.
