2.4.Features
2.4.1.Identity packet function
Figure 15 Identity Packet application diagram
Identity packet is used for identifying the device when module works as TCP client/UDP client. There are two
methods to send identity packet.
Identity packet can be MAC address or user editable identity packet. User editable identity packet should less
than 40 bytes.
2.4.2.Heartbeat packet function
Heartbeat packet: Module will output heartbeat packet to serial side or network side periodic. User can
configure the heartbeat packet data and sending interval. Serial heartbeat packet can be used for polling Modbus
data. Network heartbeat packet can be used for showing connection status and keeping the connection (only
take effect in TCP/UDP Client mode).
2.4.3.Non-persistent connection
410s support non-persistent connection function in TCP Client mode. When 410s adopts this function, 410s will
connect to server and send data after receiving data from serial port side and will disconnect to server after
sending all the data to server and no data from serial port side over 3s.
2.4.4.Modbus gateway
Modbus gateway includes: Modbus RTU transparent transmission, Modbus ASCII transparent transmission,
Modbus RTU<=>Modbus TCP protocol conversion, Modbus polling and serial port query.
Modbus RTU<=>Modbus TCP: Set 410s in TCP Server or TCP Client mode, then user can set 410s with Modbus
