4.2. Network operation mode
4.2.1.TCP server 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.
4.2.2.TCP client mode
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.
