4.8 HeartBeat, Registration packet

The heartbeat packet registration package is a function only available in the TCP client mode. This device supports

custom heartbeat packet data and registration packet data content.

This device supports Modbus protocol and can realize free conversion between RTU and TCP. When in use, you

only need to transfer data from the serial port, and the device will automatically recognize and convert it into

Modbus-compliant data, and upload it to the network. Or convert the received network-side data into data conforming to

the Modbus specification and output it from the serial port.

requires attention:

1. The Modbus supported by this device is only for data conversion and does not support actual function operations.

If you need to use this part of the function, please cooperate with the actual PLC device.

2. If the Modbus function is turned on, the protocol transmission is invalid, that is, the protocol transmission is no

longer data with a fixed format, and it will be converted to data that conforms to the modbus protocol standard.

3. Only TCP server, TCP client, UDP, MQTT, WebSocket and P2P modes support Modbus protocol. HTTP client

does not support it. The reason is because HTTP client is a short-connection communication method, and the server

cannot actively initiate data exchange.

In STA mode, it can support the setting of static IP, which is convenient for realizing fixed IP communication. It

should be noted that the static IP address must be in the same network segment as the target router or target AP, otherwise

it will not be able to assign IP and not work normally. For example, the target AP address is 10.123.45.1, then the static IP

address must be set to 10.123.45.x. Otherwise, the IP address cannot be assigned normally and the device cannot work.
