M8004 是M8060~M8067任意一個(gè)為ON時(shí)接通（M8062除外），有錯誤報警作用
M8060功能：I/O構成出錯------是程序里的I/O口設置超過(guò)PLC本身的I/O口，如128端口的，但程序里出現了第129個(gè)I/O口，然后報警，是這個(gè)意思嗎？
M8061功能：PLC硬件出錯----是不是擴展模塊接觸不良，然后報警，是這個(gè)意思嗎？
M8063功能：串行通信出錯-----什么意思？通信出錯，程序不是運行不起來(lái)嗎？當初仿真就應該知道了呀，干嘛要設置這個(gè)報警呢？
M8064功能：參數錯誤；M8065:語(yǔ)法出錯；M8066：梯形圖出錯；M8067：運算出錯---------這些都應該在仿真的時(shí)候就知道了，為什么要設置這個(gè)報警呢
求各位大蝦支點(diǎn)下
