161 +**General**
162 +
163 +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.
164 +
165 +**Protocol settings**
166 +
167 +The communication between two devices requires a protocol. The following contents show the steps of protocol settings.
168 +
169 +Please select the protocol, when creating a new project.
170 +
171 +1. Select the COM port for communication;
172 +1. PLC type: It means PLC brand, like WECON;
173 +1. PLC model: It shows the model of PLC, such as LX3V;
