請教過來師傅，想使用FX-2N編程器作簡單的溫度、液位輸入控制，能快速簡單編程應用，先從哪兒入手（思路理論）呢？                        

                                                                                                                                                                                                      謝謝！

技成李金成寫的不錯，贊成1樓。
