81 +== **LX5V serial communication** ==
82 +
83 +This example introduces the establishment of serial port communication between Wecon V-BOX and LX5V. It is introduced through three parts: PLC software configuration, HMI software configuration, and hardware wiring.
84 +
85 +**Software configuration of PLC**
86 +
87 +**1）PLC programming software**
88 +

114 +
115 +**V-BOX software configuration**
116 +
117 +**1）V-BOX programming software**
118 +
119 + [[image:image-20220824104124-1.png]]
120 +
121 +**2）V-NET add device**
122 +
123 +Open V-NET client software → add device. As shown in the figure below, click "+" in the order of steps, and the Add Device window will pop up, enter the access key, password and remark, to add the device.
124 +
125 +[[image:image-20220824104909-2.png]]
126 +
127 +
128 +**3）Set communication port parameters**
129 +
130 +Click the communication configuration button on the left to find the communication protocol with LX5V. After selecting the protocol, configure the communication parameters of the COM port.
131 +
132 +Baud rate：115200
133 +
134 +Data bit：8
135 +
136 +Stop bit：1
