欧姆龙PLC通信协议

1、欧姆龙PLC通信协议参考：W342-SYSMACCS/CJSeriesCommunicationsCommands欧姆龙通信命令可分为两类：1：C-modecommands只可通过串口通讯2：FINScommands既可通过串口通讯也可通过各类网络通信（适应性较强）下面只讲FINS命令一、命令发送FINS直连发送命令如下:SendingCommandstoaCPUUnitDirectlyConnectedtotheHostComputerNoteThefollowingformati$alsoapplicableforahostcomputerconnectedto皐SerialCammuni
