106 +**General**
107 +
108 +HMI could communicate with PLC and support many PLC protocols.  It is easy to operate and set communication parameters. This demo shows how to make a communication with PLC device, use WECON LX3V Series PLC as an example.
109 +
110 +**Protocol settings**
111 +
112 +The communication between two devices requires a protocol. The following contents show the steps of protocol settings.
113 +
114 +Please select the protocol, when creating a new project.
115 +
116 +1. Select the COM port for communication;
117 +1. PLC type: It means PLC brand, like WECON;
118 +1. PLC model: It shows the model of PLC, such as LX3V;
