請(qǐng)各位大哥幫下小弟，我現(xiàn)在用三菱FX2N與DL-RS1A通信，在DL-RS1A上RD閃爍，但是SD不閃爍沒(méi)有數(shù)據(jù)反饋回來(lái)，查資料書(shū)是通信設(shè)置問(wèn)題，但是我檢查多篇確定兩邊通信設(shè)置是一樣的，請(qǐng)各位大哥看下是什么問(wèn)題？主模塊是：GT2-71N 用的是FX2N-232BD,
                                  發(fā)送接收程序如下：MOV  H1387  D8120
                                                                      RS D100 K8 D200 K12
                                                                      MOV  H5352  D100
                                                                      MOV  H2C30  D101

                                                                      MOV  H0A00  D105
                                                                     SET  M8122  

    請(qǐng)大哥們幫幫忙，現(xiàn)在就快趕著要出機(jī)啦，謝謝啦！

不看其它，就簡(jiǎn)單的這幾句就有問(wèn)題！
數(shù)據(jù)設(shè)置要放在RS之前
