本人菜鳥，弱弱的問大家一個問題，一個儀表的通訊格式為：數(shù)據(jù)位=7
.                                                                                                           偶校驗，
                                                                                                             終止位=1。
                                                                                                            編碼標準=ASCII碼。
                                                                                                            波特率=19200。
                                                                                                           結(jié)束碼=CR/LF
如果和三菱的PLC通訊數(shù)據(jù)應該是多少？

看RS指令，與之對應即可。
發(fā)送什么指令還要看通訊協(xié)議。
