| Wrong Practice | Consequence | Correct Operation |
| No spare I/O reserved | Impossible later expansion | Reserve 20~30% spare points |
| Wrong output selection | Frequently burnt output points | AC load→Relay;High-speed DC→Transistor |
| Underestimate expansion | Unable to add required modules | Prefer AE/AA expandable models |
| Ignore communication | Fail HMI/PC connection | Select Ethernet version for remote monitoring |
| Select obsolete Twido for new project | Hard spare parts sourcing | New projects adopt M221 replacement |
- Selection Example: Small Bottle Filler
I/O Budget:18에서(감지기)+12~하다(valve/motor)=30 → choose 40-point PLC
Power Source: Factory AC →100–240V AC
산출:10 valves(계전기)+2 stepper(트랜지스터)=DR mixed output
확장:Need analog module for liquid level → AE 7-module expandable
의사소통:HMI+PC via Ethernet+RS485
Final Choice:TWDLCAE40DRF, substitute TM221CE40R
