本人菜鸟，弱弱的问大家一个问题，一个仪表的通讯格式为：数据位=7
.                                                                                                           偶校验，
                                                                                                             终止位=1。
                                                                                                            编码标准=ASCII码。
                                                                                                            波特率=19200。
                                                                                                           结束码=CR/LF
如果和三菱的PLC通讯数据应该是多少？

看RS指令，与之对应即可。
发送什么指令还要看通讯协议。
