When designing systems with dense distributed remote I\/O arrays, set the Requested Packet Interval (RPI) values carefully. Assigning RPIs below 10 ms across more than 10 connected devices can lead to communication buffer starvation and cyclic task overruns. Ensure that the 5V DC power budget of the rack's power supply unit (e.g., CJ1W-PA202) is calculated correctly; the CJ2M-CPU33 draws 700 mA, which must be subtracted from the total bus current limit before allocating auxiliary standard I\/O units.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eInitial IP address parameters must be set via the USB port using CX-Programmer before attempting to connect over the TCP\/IP interface.
