之前，分享过一些双手启动的例子，最近看到一种方法，展示出来供参考。

                          X35                                                            X36
---------------------▏      ▏-----------------------------------------------▏       ▏--------------------------------------------------------[PLS    M12   ]
                    双手启动（左）                                            双手启动（右）
                                      M12                                    C6
-------------------------------▏       ▏---------------------------▏  /    ▏-----------------------------------------------------------------------（ Y18    ）  
                                 双手启动         ▏               双手启动计数                                                                                       输出
                                                        ▏
                             Y18                     ▏
-------------------------▏       ▏-------------
                             自锁
                                      M12                                        
-------------------------------▏       ▏--------------------------------------------------------------------------------------------------------------(C6    K2)
                                  双手启动                                                                                                                                双手启动计数

                                      C6
-------------------------------▏       ▏---------------------------------------------------------------------------------------------------------------(T8  K15)
                                   双手启动计数                                                                                                                     双手启动两次开始计时

                                      T8
------------------------------▏        ▏---------------------------------------------------------------------------------------------------------------[RST  C6 ]
                                   时间到闭合                                                                                                                                 C6复位

以上，仅供参考。

这就相当于单按钮启停
