4.2. Network operation mode

TCP Server is a TCP server. In the TCP Server mode, the device listens to the local port,

accepts the connection request of the client and establishes a connection for data

communication, which is usually used for communication with TCP clients in the LAN.

When the Modbus gateway function is turned off, the device will send the data received

by the serial port to all the client devices that have established a connection with the device.

At most, it can connect 6 clients. After the Modbus gateway function is enabled, the

non-Modbus data will be cleared and will not be forwarded.

TCP Client is the TCP client. When the device works, it will actively send a connection

request to the server and establish a connection to realize the interaction between serial port

data and server data.

To use the client, you need to configure the IP address/domain name and target port of

the target accurately.
