4.2. Special feature

In network transparent transmission mode, users can choose to let ECAN-E01S send heartbeat packets.

Heartbeat packets can be sent to the network server. The main purpose of sending to the network is to maintain a

connection with the server, and it only takes effect in TCP Client and UDP Client modes. ECAN-E01S module

supports custom heartbeat packet content up to 128 bytes. Support custom heartbeat package.

In the network transparent transmission mode, the user can choose to let the DTU send the registration packet to the

server. The registration package is used to allow the server to identify the data source device, or as a password to

Because the speed of Ethernet is much higher than the

transmission speed of CAN, if the amount of data

received by Ethernet is too large, CAN needs to buffer

transmission, which can ensure that no frames are lost,

but such a large buffer may lead to poor real-time

performance, that is, Ethernet The data currently sent

by the network needs to wait for a certain time to be

sent out from the CAN interface. In this case, the

client needs to control the transmission speed of the

Ethernet to match the transmission speed of the CAN
