5.4 Working Mode Instructions
When the device configuration is completed, the device works in the specific mode. The following describes
how to use each work mode based on ZCANPRO software.
5.4.1 TCP Server Mode
In TCP Server mode, the device will not actively connect with other devices. It always waits for the
connection of the client (TCP Client), and can carry out two-way data communication after establishing a TCP
connection with the client.
When the device acts as a TCP server, the PC should act as a TCP client. Open the [Device Management]
interface of ZCANPRO, select CANFDNET-TCP as the device type, and start the device.
On the device startup interface (as shown in Figure 5.8), select [Work Mode] as [Client], and enter [IP
address] and [working port]. If the current device IP address is "192.168.0.178" and the port is 8000, enter this
parameter.
[Protocol] is determined by the [controller type] of CAN configuration. If it is configured as a CAN controller,
select CAN; if it is configured as ISO/Non-ISO CANFD, select CANFD.

[CANFD acceleration] is determined by the user. When [No] is selected, all CANFD messages sent are not
accelerated; otherwise, they are all accelerated.
Click [OK]. ZCANPRO will connect to the device.
Figure 5.8 Starting the CANFDNET-TCP client
After starting the device, you can use ZCANPRO to communicate with the device. To verify whether the
device communication is normal, connect CAN0 and CAN1 of the device (the baud rate must be the same) to
carry out the message sending and receiving test.
Click the [Send Data] icon on the ZCANPRO interface and select [Normal Send]. On the displayed sending
interface, select [Channel] to specify the sending channel, and click [Send Now] to send the message.
As CAN0 is connected to CAN1, the message sent by CAN0 will be received by CAN1. You can see two
messages on the main interface. One is the sending message and the other is the receiving message, from
CAN0 and CAN1 respectively, as shown in Figure 5.9.

User Manual
Figure 5.9 Message sending interface
So far, the basic use of CANFDNET equipment has been realized.
5.4.2 TCP Client Mode
In TCP Client mode, the device will actively connect to the preset TCP server. If the connection is
unsuccessful, the client will continue to try to establish a connection with the TCP server based on the preset
connection conditions. After establishing a TCP connection with the TCP server, two-way data communication
can be carried out.
When the device acts as a TCP Client, the PC should act as a TCP server. Open the [Device Management]
interface of ZCANPRO, select CANFDNET-TCP as the device type, and start the device.
On the pop-up startup device interface (as shown in Figure 5.10), set [Work Mode] to [Server], and enter
[Local Port]. For example, the current device IP address is "192.168.0.178", the target IP address of the client
connection is "192.168.0.55", and the target port is 8000. On the ZCANPRO startup interface, set [local port] to
8000, and change the IP address of the PC to "192.168.0.55".

User Manual
Figure 5.10 Starting the CANFDNET-TCP server
Click [OK]. The device connects to ZCANPRO. The communication with the device is set up. For
communication information, see TCP Server mode.
5.4.3 UDP Mode
In UDP mode, the UDP protocol is used for data communication. UDP is a non-connection-based
communication method. It cannot guarantee that the data packets sent to the target host will be received correctly.
Therefore, in the scenarios with high reliability requirements, the upper-layer communication protocol must be
used to ensure that the data is correct; however, because UDP is a simple communication method, it will not
increase too much additional communication volume, and can provide a higher communication speed than the
TCP method to ensure the real-time transmission of data packets. In fact, when the network environment is
simple and the network communication load is not too large, the UDP working method is not error prone. The
devices working in this mode are equal, and there is no server and client.
When the device is in UDP mode, the PC should also work in UDP mode. On the [Device Management]
interface of ZCANPRO, set the device type to [CANFDNET-UDP], and start the device.
On the displayed startup device interface (as shown in Figure 5.11), set [local port], [IP address], and
[working port]. For example, if the current device IP address is "192.168.0.178", the connection target IP address
is "192.168.0.55", the target port is 8000, and the local port is 4001, set [Local Port] to the device target port 8000,
[IPAddress] to the device IP address "192.168.0.178", and [Working Port] to the device local port 4001.
