请各位大哥帮下小弟，我现在用三菱FX2N与DL-RS1A通信，在DL-RS1A上RD闪烁，但是SD不闪烁没有数据反馈回来，查资料书是通信设置问题，但是我检查多篇确定两边通信设置是一样的，请各位大哥看下是什么问题？主模块是：GT2-71N 用的是FX2N-232BD,
                                  发送接收程序如下：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  

    请大哥们帮帮忙，现在就快赶着要出机啦，谢谢啦！
