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  H302C  D102
                                                                      MOV  H3030  D103
                                                                      MOV  H330D  D104
                                                                      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
